+          <p>When a <span class="pop" id="bookie-popover">bookie</span> crashes, all <span class="pop" id="ledger-popover">ledgers</span> on that bookie become under-replicated. In order to bring all ledgers in your BookKeeper cluster back to full replication, you’ll need to <em>recover</em> the data from any offline bookies. There are two ways to recover bookies’ data:</p>
+
+<ol>
+  <li>Using <a href="#manual-recovery">manual recovery</a></li>
+  <li>Automatically, using <a href="#autorecovery"><em>AutoRecovery</em></a></li>
+</ol>
+
+<h2 id="manual-recovery">Manual recovery</h2>
+
+<p>You can manually recover failed bookies using the <a href="../../reference/cli"><code class="highlighter-rouge">bookkeeper</code></a> command-line tool. You need to specify:</p>
+
+<ul>
+  <li>the <code class="highlighter-rouge">shell recover</code> option</li>
+  <li>an IP and port for your BookKeeper cluster’s ZooKeeper ensemble</li>
+  <li>the IP and port for the failed bookie</li>
+</ul>
+
+<p>Here’s an example:</p>
+
+<div class="language-bash highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>bookkeeper-server/bin/bookkeeper shell recover <span class="se">\</span>
+  zk1.example.com:2181 <span class="se">\ </span><span class="c"># IP and port for ZooKeeper</span>
+  192.168.1.10:3181      <span class="c"># IP and port for the failed bookie</span>
+</code></pre></div></div>
+
+<p>If you wish, you can also specify which bookie you’d like to rereplicate to. Here’s an example:</p>
+
+<div class="language-bash highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>bookkeeper-server/bin/bookkeeper shell recover <span class="se">\</span>
+  zk1.example.com:2181 <span class="se">\ </span><span class="c"># IP and port for ZooKeeper</span>
+  192.168.1.10:3181 <span class="se">\ </span>   <span class="c"># IP and port for the failed bookie</span>
+  192.168.1.11:3181      <span class="c"># IP and port for the bookie to rereplicate to</span>
+</code></pre></div></div>
+
+<h3 id="the-manual-recovery-process">The manual recovery process</h3>
+
+<p>When you initiate a manual recovery process, the following happens:</p>
+
+<ol>
+  <li>The client (the process running ) reads the metadata of active ledgers from ZooKeeper.</li>
+  <li>The ledgers that contain fragments from the failed bookie in their ensemble are selected.</li>
+  <li>A recovery process is initiated for each ledger in this list and the rereplication process is run for each ledger.</li>
+  <li>Once all the ledgers are marked as fully replicated, bookie recovery is finished.</li>
+</ol>
+
+<h2 id="autorecovery">AutoRecovery</h2>
+
+<p>AutoRecovery is a process that:</p>
+
+<ul>
+  <li>automatically detects when a <span class="pop" id="bookie-popover">bookie</span> in your BookKeeper cluster has become unavailable and then</li>
+  <li>rereplicates all the <span class="pop" id="ledger-popover">ledgers</span> that were stored on that bookie.</li>
+</ul>
+
+<p>AutoRecovery can be run in two ways:</p>
+
+<ol>
+  <li>On dedicated nodes in your BookKeeper cluster</li>
+  <li>On the same machines on which your bookies are running</li>
+</ol>
+
+<h2 id="running-autorecovery">Running AutoRecovery</h2>
+
+<p>You can start up AutoRecovery using the <a href="../../reference/cli#bookkeeper-autorecovery"><code class="highlighter-rouge">autorecovery</code></a> command of the <a href="../../reference/cli"><code class="highlighter-rouge">bookkeeper</code></a> CLI tool.</p>
+
+<div class="language-bash highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>bookkeeper-server/bin/bookkeeper autorecovery
+</code></pre></div></div>
+
+<blockquote>
+  <p>The most important thing to ensure when starting up AutoRecovery is that the ZooKeeper connection string specified by the <a href="../../reference/config#zkServers"><code class="highlighter-rouge">zkServers</code></a> parameter points to the right ZooKeeper cluster.</p>
+</blockquote>
+
+<p>If you start up AutoRecovery on a machine that is already running a bookie, then the AutoRecovery process will run alongside the bookie on a separate thread.</p>
+
+<p>You can also start up AutoRecovery on a fresh machine if you’d like to create a dedicated cluster of AutoRecovery nodes.</p>
+
+<h2 id="configuration">Configuration</h2>
+
+<p>There are a handful of AutoRecovery-related configs in the <a href="../../reference/config"><code class="highlighter-rouge">bk_server.conf</code></a> configuration file. For a listing of those configs, see <a href="../../reference/config#autorecovery-settings">AutoRecovery settings</a>.</p>
+
+<h2 id="disable-autorecovery">Disable AutoRecovery</h2>
+
+<p>You can disable AutoRecovery at any time, for example during maintenance. Disabling AutoRecovery ensures that bookies’ data isn’t unnecessarily rereplicated when the bookie is only taken down for a short period of time, for example when the bookie is being updated or the configuration if being changed.</p>
+
+<p>You can disable AutoRecover using the <a href="../../reference/cli#bookkeeper-shell-autorecovery"><code class="highlighter-rouge">bookkeeper</code></a> CLI tool:</p>
+
+<div class="language-bash highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>bookkeeper-server/bin/bookkeeper shell autorecovery <span class="nt">-disable</span>
+</code></pre></div></div>
+
+<p>Once disabled, you can reenable AutoRecovery using the <a href="../../reference/cli#bookkeeper-shell-autorecovery"><code class="highlighter-rouge">enable</code></a> shell command:</p>
+
+<div class="language-bash highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>bookkeeper-server/bin/bookkeeper shell autorecovery <span class="nt">-enable</span>
+</code></pre></div></div>
+
+<h2 id="autorecovery-architecture">AutoRecovery architecture</h2>
+
+<p>AutoRecovery has two components:</p>
+
+<ol>
+  <li>The <a href="#auditor"><strong>auditor</strong></a> (see the <a href="../../api/javadoc/org/apache/bookkeeper/replication/Auditor.html"><code class="highlighter-rouge">Auditor</code></a> class) is a singleton node that watches bookies to see if they fail and creates rereplication tasks for the ledgers on failed bookies.</li>
+  <li>The <a href="#replication-worker"><strong>replication worker</strong></a> (see the <a href="../../api/javadoc/org/apache/bookkeeper/replication/ReplicationWorker.html"><code class="highlighter-rouge">ReplicationWorker</code></a> class) runs on each bookie and executes rereplication tasks provided by the auditor.</li>
+</ol>
+
+<p>Both of these components run as threads in the <a href="../../api/javadoc/org/apache/bookkeeper/replication/AutoRecoveryMain"><code class="highlighter-rouge">AutoRecoveryMain</code></a> process, which runs on each bookie in the cluster. All recovery nodes participate in leader election—using ZooKeeper—to decide which node becomes the auditor. Nodes that fail to become the auditor watch the elected auditor and run an election process again if they see that the auditor node has failed.</p>
+
+<h3 id="auditor">Auditor</h3>
+
+<p>The auditor watches all bookies in the cluster that are registered with ZooKeeper. Bookies register with ZooKeeper at startup. If the bookie crashes or is killed, the bookie’s registration in ZooKeeper disappears and the auditor is notified of the change in the list of registered bookies.</p>
+
+<p>When the auditor sees that a bookie has disappeared, it immediately scans the complete <span class="pop" id="ledger-popover">ledger</span> list to find ledgers that have data stored on the failed bookie. Once it has a list of ledgers for that bookie, the auditor will publish a rereplication task for each ledger under the <code class="highlighter-rouge">/underreplicated/</code> <a href="https://zookeeper.apache.org/doc/current/zookeeperOver.html">znode</a> in ZooKeeper.</p>
+
+<h3 id="replication-worker">Replication Worker</h3>
+
+<p>Each replication worker watches for tasks being published by the auditor on the <code class="highlighter-rouge">/underreplicated/</code> znode in ZooKeeper. When a new task appears, the replication worker will try to get a lock on it. If it cannot acquire the lock, it will try the next entry. The locks are implemented using ZooKeeper ephemeral znodes.</p>
+
+<p>The replication worker will scan through the rereplication task’s ledger for fragments of which its local bookie is not a member. When it finds fragments matching this criterion, it will replicate the entries of that fragment to the local bookie. If, after this process, the ledger is fully replicated, the ledgers entry under /underreplicated/ is deleted, and the lock is released. If there is a problem replicating, or there are still fragments in the ledger which are still underreplica [...]
+
+<p>If the replication worker finds a fragment which needs rereplication, but does not have a defined endpoint (i.e. the final fragment of a ledger currently being written to), it will wait for a grace period before attempting rereplication. If the fragment needing rereplication still does not have a defined endpoint, the ledger is fenced and rereplication then takes place.</p>
+
+<p>This avoids the situation in which a client is writing to a ledger and one of the bookies goes down, but the client has not written an entry to that bookie before rereplication takes place. The client could continue writing to the old fragment, even though the ensemble for the fragment had changed. This could lead to data loss. Fencing prevents this scenario from happening. In the normal case, the client will try to write to the failed bookie within the grace period, and will have sta [...]
+
+<p>You can configure this grace period using the <a href="../../reference/config#openLedgerRereplicationGracePeriod"><code class="highlighter-rouge">openLedgerRereplicationGracePeriod</code></a> parameter.</p>
+
+<h3 id="the-rereplication-process">The rereplication process</h3>
+
+<p>The ledger rereplication process happens in these steps:</p>
+
+<ol>
+  <li>The client goes through all ledger fragments in the ledger, selecting those that contain the failed bookie.</li>
+  <li>A recovery process is initiated for each ledger fragment in this list.
+    <ol>
+      <li>The client selects a bookie to which all entries in the ledger fragment will be replicated; In the case of autorecovery, this will always be the local bookie.</li>
+      <li>The client reads entries that belong to the ledger fragment from other bookies in the ensemble and writes them to the selected bookie.</li>
+      <li>Once all entries have been replicated, the zookeeper metadata for the fragment is updated to reflect the new ensemble.</li>
+      <li>The fragment is marked as fully replicated in the recovery tool.</li>
+    </ol>
+  </li>
+  <li>Once all ledger fragments are marked as fully replicated, the ledger is marked as fully replicated.</li>
+</ol>

+          <p>This document is a guide to deploying, administering, and maintaining BookKeeper. It also discusses <a href="#best-practices">best practices</a> and <a href="#common-problems">common problems</a>.</p>
+
+<h2 id="requirements">Requirements</h2>
+
+<p>A typical BookKeeper installation consists of an ensemble of <span class="pop" id="bookie-popover">bookies</span> and a ZooKeeper quorum. The exact number of bookies depends on the quorum mode that you choose, desired throughput, and the number of clients using the installation simultaneously.</p>
+
+<p>The minimum number of bookies depends on the type of installation:</p>
+
+<ul>
+  <li>For <em>self-verifying</em> entries you should run at least three bookies. In this mode, clients store a message authentication code along with each <span class="pop" id="entry-popover">entry</span>.</li>
+  <li>For <em>generic</em> entries you should run at least four</li>
+</ul>
+
+<p>There is no upper limit on the number of bookies that you can run in a single ensemble.</p>
+
+<h3 id="performance">Performance</h3>
+
+<p>To achieve optimal performance, BookKeeper requires each server to have at least two disks. It’s possible to run a bookie with a single disk but performance will be significantly degraded.</p>
+
+<h3 id="zookeeper">ZooKeeper</h3>
+
+<p>There is no constraint on the number of ZooKeeper nodes you can run with BookKeeper. A single machine running ZooKeeper in <a href="https://zookeeper.apache.org/doc/current/zookeeperStarted.html#sc_InstallingSingleMode">standalone mode</a> is sufficient for BookKeeper, although for the sake of higher resilience we recommend running ZooKeeper in <a href="https://zookeeper.apache.org/doc/current/zookeeperStarted.html#sc_RunningReplicatedZooKeeper">quorum mode</a> with multiple servers.</p>
+
+<h2 id="starting-and-stopping-bookies">Starting and stopping bookies</h2>
+
+<p>You can run bookies either in the foreground or in the background, using <a href="https://en.wikipedia.org/wiki/Nohup">nohup</a>. You can also run <a href="#local-bookie">local bookies</a> for development purposes.</p>
+
+<p>To start a bookie in the foreground, use the <a href="../../reference/cli#bookkeeper-bookie"><code class="highlighter-rouge">bookie</code></a> command of the <a href="../../reference/cli#bookkeeper"><code class="highlighter-rouge">bookkeeper</code></a> CLI tool:</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>bookkeeper-server/bin/bookkeeper bookie
+</code></pre></div></div>
+
+<p>To start a bookie in the background, use the <a href="../../reference/cli#bookkeeper-daemon.sh"><code class="highlighter-rouge">bookkeeper-daemon.sh</code></a> script and run <code class="highlighter-rouge">start bookie</code>:</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>bookkeeper-server/bin/bookkeeper-daemon.sh start bookie
+</code></pre></div></div>
+
+<h3 id="local-bookies">Local bookies</h3>
+
+<p>The instructions above showed you how to run bookies intended for production use. If you’d like to experiment with ensembles of bookies locally, you can use the <a href="../../reference/cli#bookkeeper-localbookie"><code class="highlighter-rouge">localbookie</code></a> command of the <code class="highlighter-rouge">bookkeeper</code> CLI tool and specify the number of bookies you’d like to run.</p>
+
+<p>This would spin up a local ensemble of 6 bookies:</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>bookkeeper-server/bin/bookkeeper localbookie 6
+</code></pre></div></div>
+
+<blockquote>
+  <p>When you run a local bookie ensemble, all bookies run in a single JVM process.</p>
+</blockquote>
+
+<h2 id="configuring-bookies">Configuring bookies</h2>
+
+<p>There’s a wide variety of parameters that you can set in the bookie configuration file in <code class="highlighter-rouge">bookkeeper-server/conf/bk_server.conf</code> of your <a href="../../reference/config">BookKeeper installation</a>. A full listing can be found in <a href="../../reference/config">Bookie configuration</a>.</p>
+
+<p>Some of the more important parameters to be aware of:</p>

+
+<blockquote>
+  <p>Ideally, the directories specified <code class="highlighter-rouge">journalDirectory</code> and <code class="highlighter-rouge">ledgerDirectories</code> should be on difference devices.</p>
+</blockquote>
+
+<h2 id="logging">Logging</h2>
+
+<p>BookKeeper uses <a href="http://www.slf4j.org/">slf4j</a> for logging, with <a href="https://logging.apache.org/log4j/2.x/">log4j</a> bindings enabled by default.</p>
+
+<p>To enable logging for a bookie, create a <code class="highlighter-rouge">log4j.properties</code> file and point the <code class="highlighter-rouge">BOOKIE_LOG_CONF</code> environment variable to the configuration file. Here’s an example:</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span><span class="nb">export </span><span class="nv">BOOKIE_LOG_CONF</span><span class="o">=</span>/some/path/log4j.properties
+<span class="nv">$ </span>bookkeeper-server/bin/bookkeeper bookie
+</code></pre></div></div>
+
+<h2 id="upgrading">Upgrading</h2>
+
+<p>From time to time you may need to make changes to the filesystem layout of bookies—changes that are incompatible with previous versions of BookKeeper and require that directories used with previous versions are upgraded. If a filesystem upgrade is required when updating BookKeeper, the bookie will fail to start and return an error like this:</p>

+<div class="highlighter-rouge"><div class="highlight"><pre class="highlight"><code>2017-05-25 10:41:50,494 - ERROR - [main:Bookie@246] - Directory layout version is less than 3, upgrade needed
+</code></pre></div></div>
+
+<p>BookKeeper provides a utility for upgrading the filesystem. You can perform an upgrade using the <a href="../../reference/cli#bookkeeper-upgrade"><code class="highlighter-rouge">upgrade</code></a> command of the <code class="highlighter-rouge">bookkeeper</code> CLI tool. When running <code class="highlighter-rouge">bookkeeper upgrade</code> you need to specify one of three flags:</p>
+
+<table>
+  <thead>
+    <tr>
+      <th style="text-align: left">Flag</th>
+      <th style="text-align: left">Action</th>
+    </tr>
+  </thead>
+  <tbody>
+    <tr>
+      <td style="text-align: left"><code class="highlighter-rouge">--upgrade</code></td>
+      <td style="text-align: left">Performs an upgrade</td>
+    </tr>
+    <tr>
+      <td style="text-align: left"><code class="highlighter-rouge">--rollback</code></td>
+      <td style="text-align: left">Performs a rollback to the initial filesystem version</td>
+    </tr>
+    <tr>
+      <td style="text-align: left"><code class="highlighter-rouge">--finalize</code></td>
+      <td style="text-align: left">Marks the upgrade as complete</td>
+    </tr>
+  </tbody>
+</table>
+
+<h3 id="upgrade-pattern">Upgrade pattern</h3>
+
+<p>A standard upgrade pattern is to run an upgrade…</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>bookkeeper-server/bin/bookkeeper upgrade <span class="nt">--upgrade</span>
+</code></pre></div></div>
+
+<p>…then check that everything is working normally, then kill the bookie. If everything is okay, finalize the upgrade…</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>bookkeeper-server/bin/bookkeeper upgrade <span class="nt">--finalize</span>
+</code></pre></div></div>
+
+<p>…and then restart the server:</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>bookkeeper-server/bin/bookkeeper bookie
+</code></pre></div></div>
+
+<p>If something has gone wrong, you can always perform a rollback:</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>bookkeeper-server/bin/bookkeeper upgrade <span class="nt">--rollback</span>
+</code></pre></div></div>
+
+<h2 id="formatting">Formatting</h2>
+
+<p>You can format bookie metadata in ZooKeeper using the <a href="../../reference/cli#bookkeeper-shell-metaformat"><code class="highlighter-rouge">metaformat</code></a> command of the <a href="../../reference/cli#the-bookkeeper-shell">BookKeeper shell</a>.</p>
+
+<p>By default, formatting is done in interactive mode, which prompts you to confirm the format operation if old data exists. You can disable confirmation using the <code class="highlighter-rouge">-nonInteractive</code> flag. If old data does exist, the format operation will abort <em>unless</em> you set the <code class="highlighter-rouge">-force</code> flag. Here’s an example:</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>bookkeeper-server/bin/bookkeeper shell metaformat
+</code></pre></div></div>
+
+<p>You can format the local filesystem data on a bookie using the <a href="../../reference/cli#bookkeeper-shell-bookieformat"><code class="highlighter-rouge">bookieformat</code></a> command on each bookie. Here’s an example:</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>bookkeeper-server/bin/bookkeeper shell bookieformat
+</code></pre></div></div>
+
+<blockquote>
+  <p>The <code class="highlighter-rouge">-force</code> and <code class="highlighter-rouge">-nonInteractive</code> flags are also available for the <code class="highlighter-rouge">bookieformat</code> command.</p>
+</blockquote>
+
+<h2 id="autorecovery">AutoRecovery</h2>
+
+<p>For a guide to AutoRecovery in BookKeeper, see <a href="../autorecovery">this doc</a>.</p>
+
+<h2 id="missing-disks-or-directories">Missing disks or directories</h2>
+
+<p>Accidentally replacing disks or removing directories can cause a bookie to fail while trying to read a ledger fragment that, according to the ledger metadata, exists on the bookie. For this reason, when a bookie is started for the first time, its disk configuration is fixed for the lifetime of that bookie. Any change to its disk configuration, such as a crashed disk or an accidental configuration change, will result in the bookie being unable to start. That will throw an error like this:</p>
+
+<div class="highlighter-rouge"><div class="highlight"><pre class="highlight"><code>2017-05-29 18:19:13,790 - ERROR - [main:BookieServer314] – Exception running bookie server : @
+org.apache.bookkeeper.bookie.BookieException$InvalidCookieException
+.......at org.apache.bookkeeper.bookie.Cookie.verify(Cookie.java:82)
+.......at org.apache.bookkeeper.bookie.Bookie.checkEnvironment(Bookie.java:275)
+.......at org.apache.bookkeeper.bookie.Bookie.&lt;init&gt;(Bookie.java:351)
+</code></pre></div></div>
+
+<p>If the change was the result of an accidental configuration change, the change can be reverted and the bookie can be restarted. However, if the change <em>cannot</em> be reverted, such as is the case when you want to add a new disk or replace a disk, the bookie must be wiped and then all its data re-replicated onto it.</p>
+
+<ol>
+  <li>Increment the <a href="../../reference/config#bookiePort"><code class="highlighter-rouge">bookiePort</code></a> parameter in the <a href="../../reference/config"><code class="highlighter-rouge">bk_server.conf</code></a></li>
+  <li>Ensure that all directories specified by <a href="../../reference/config#journalDirectory"><code class="highlighter-rouge">journalDirectory</code></a> and <a href="../../reference/config#ledgerDirectories"><code class="highlighter-rouge">ledgerDirectories</code></a> are empty.</li>
+  <li><a href="#starting-and-stopping-bookies">Start the bookie</a>.</li>
+  <li>
+    <p>Run the following command to re-replicate the data:</p>
+
+    <div class="language-bash highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>bookkeeper-server/bin/bookkeeper shell recover <span class="se">\</span>
+  &lt;zkserver&gt; <span class="se">\</span>
+  &lt;oldbookie&gt; <span class="se">\</span>
+  &lt;newbookie&gt;
+</code></pre></div>    </div>
+
+    <p>The ZooKeeper server, old bookie, and new bookie, are all identified by their external IP and <code class="highlighter-rouge">bookiePort</code> (3181 by default). Here’s an example:</p>
+
+    <div class="language-bash highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$ </span>bookkeeper-server/bin/bookkeeper shell recover <span class="se">\</span>
