[jira] [Commented] (CASSANDRA-8327) snapshots taken before repair
are not cleared if snapshot fails
[ https://issues.apache.org/jira/browse/CASSANDRA-8327?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14214947#comment-14214947 ]
Nick Bailey commented on CASSANDRA-8327:
----------------------------------------
I think that ideally, c* would be using a specific directory for snapshots created by repair. In addition to cleaning up after the snapshot fails for some reason, c* can be restarted while a repair is ongoing and leave these directories behind. By using a specific directory, the c* process can also simply clean up this directory when the process starts.

> Key: CASSANDRA-8327
> URL: https://issues.apache.org/jira/browse/CASSANDRA-8327
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Environment: cassandra 2.0.10.71
> Reporter: MASSIMO CELLI
> Priority: Minor
>
> running repair service the following directory was created for the snapshots:
> drwxr-xr-x 2 cassandra cassandra 36864 Nov 5 07:47 073d16e0-64c0-11e4-8e9a-7b3d4674c508
> but the system.log reports the following error which suggests the snapshot failed:
> ERROR [RMI TCP Connection(3251)-10.150.27.78] 2014-11-05 07:47:55,734 StorageService.java (line 2599) Repair session 073d16e0-64c0-11e4-8e9a-7b3d4674c508 for range (7530018576963469312,7566047373982433280] failed with error java.io.IOException: Failed during snapshot creation. java.util.concurrent.ExecutionException: java.lang.RuntimeException: java.io.IOException: Failed during snapshot creation. .... ERROR [AntiEntropySessions:3312] 2014-11-05 07:47:55,731 RepairSession.java (line 288) [repair #073d16e0-64c0-11e4-8e9a-7b3d4674c508] session completed with the following error java.io.IOException: Failed during snapshot creation.
> the problem is that the directory for the snapshots that fail are just left on the disk and don't get cleaned up. They must be removed manually, which is not ideal.
