Apache CloudStack Advisory on KVM Shared Mount Point issues on version 4.17.0.0
On 14th June 2022, a new issue affecting only KVM users using Shared
Mount Point storage was reported [1]. This issue affects the creation
and the usage of existing Shared Mount Point storage pools on Apache
CloudStack 4.17.0.0.
Apache CloudStack 4.17.0.0 added support for the StorPool storage
based on Shared Mount Point. However, the current version of
CloudStack doesn’t allow multiple implementations of Shared Mount
Point storage pool providers, causing the StorPool provider to
override the default implementation. This affected the other storage
pool providers for Shared Mount Point since CloudStack tries to add
them as a StorPool storage pool.
To mitigate the issue, a CloudStack administrator needs to do the
following on version 4.17.0.0:
- On each management server: stop the CloudStack management service, remove the Storpool plugin jar on /usr/share/cloudstack-management/lib/cloud-plugin-storage-volume-storpool-4.17.0.0.jar and restart the Cloudstack management service
- On each KVM host: stop the CloudStack agent service, remove the StorPool plugin jar on /usr/share/cloudstack-agent/lib/cloud-plugin-storage-volume-storpool-4.17.0.0.jar and restart the CloudStack agent service
Note: This workaround removes the StorPool plugin support. StorPool
users should not apply the workaround to continue using their Storpool
storage.
This issue will be fixed in the upcoming CloudStack version 4.17.1.0.
