----------------------------------------------
Summary: ceph: Volume operations can fail if libvirt lost the
storage pool
Key: CLOUDSTACK-6783
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-6783
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: KVM
Affects Versions: 4.2.0, Future, 4.3.0, 4.4.0
Reporter: Wido den Hollander
Assignee: Wido den Hollander
Priority: Critical
Fix For: 4.4.0
When libvirt lost the RBD storage pool, could be due to a libvirt restart, the
KVM Agent will re-create the storage pool.
When doing so the createStoragePool() method in LibvirtStoragePoolAdapter
doesn't return a properly filled LibvirtStoragePool object.
This can lead to situations where the agent for example tries to delete a
volume, but that fails:
"Unprotecting and Removing RBD snapshots of image
null/7a3bdc9f-5cd3-4192-a814-18acf561f0d0 prior to removing the image
Failed to delete volume: com.cloud.utils.exception.CloudRuntimeException:
com.ceph.rados.RadosException: Could not set configuration option key (-22)"
Notice the "null" in the first line, it's because this information is not
properly filled in the returned object.
