NullPointerException on agent while remounting primary storage
Hi all.
I'm using CS 4.2.0 / CentOS 6.4/KVM and I faced the following problem:
-no new virtalmachines are created on one of hypervisor servers
-there are NullPointerExceptions in agent log on problem server
-virsh shows no pools
After doing some debugging I was able to repeat this bug manually(see
below), but still have no idea how it occured initially.
I've filed it to https://issues.apache.org/jira/browse/CLOUDSTACK-4867
Here are steps to reproduce this bug:
I have two primary storages mounted via NFS:
10.6.20.1:/GIGO1/p1 7.2T 90G 7.1T 2%
/mnt/c59065c8-4d4c-3276-9d12-f170e4cd445e
10.6.20.2:/GIGO2/p2 7.3T 31G 7.3T 1%
/mnt/bd32f762-a1f0-3a65-b9bc-fdb6d1d681b5
You should have at least one VM running from NFS storage to reproduce this
issue.
[root@ad111 libvirt]# virsh pool-list
Name State Autostart
-----------------------------------------
63cacc3d-185f-45f0-981c-5c4d9d79d665 active no
bd32f762-a1f0-3a65-b9bc-fdb6d1d681b5 active no
c59065c8-4d4c-3276-9d12-f170e4cd445e active no
for now all is ok, I can see localstorage and two NFS shares in pool-list
Let's restart libvirtd:
[root@ad111 ~]# /etc/init.d/libvirtd restart
Stopping libvirtd daemon: [ OK ]
Starting libvirtd daemon: [ OK ]
And pools are gone:
[root@ad111 ~]# virsh pool-list
Name State Autostart
-----------------------------------------
[root@ad111 ~]#
According to agent log it tries to add pool to libvirt but it fails because
libvirt tries to mount share (which is already mounted) upon adding it:
[root@ad111 ~]# cat << _EOF > pool.xml
<pool type='netfs'>
<name>c59065c8-4d4c-3276-9d12-f170e4cd445e</name>

_EOF
[root@ad111 ~]# virsh pool-create pool.xml
error: Failed to create pool from pool.xml
error: Requested operation is not valid: Target
'/mnt/c59065c8-4d4c-3276-9d12-f170e4cd445e' is already mounted
Agent loops in java.lang.NullPointerExceptions, restart does not help. As a
result, no new VMs could be created on this host.
I was able to resolve this issue next way:
-migrated all vms to another node
-switched on maintenance mode on the problem host
-umount all NFS shares
-switched off maintenance mode on the problem host
