Apache CloudStack Advisory on KVM Shared Mount Point issues on version 4.17.0.0
66-
===============================================================================
67-
68-
On 14th June 2022, a new issue affecting only KVM users using Shared
69-
Mount Point storage was reported [1]. This issue affects the creation
70-
and the usage of existing Shared Mount Point storage pools on Apache
71-
CloudStack 4.17.0.0.
72-
73-
Apache CloudStack 4.17.0.0 added support for the StorPool storage
74-
based on Shared Mount Point. However, the current version of
75-
CloudStack doesn't allow multiple implementations of Shared Mount
76-
Point storage pool providers, causing the StorPool provider to
77-
override the default implementation. This affected the other storage
78-
pool providers for Shared Mount Point since CloudStack tries to add
79-
them as a StorPool storage pool.
80-
81-
To mitigate the issue, a CloudStack administrator needs to do the
82-
following on version 4.17.0.0:
83-
84-
• 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
85-
• 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
86-
87-
Note: This workaround removes the StorPool plugin support. StorPool
88-
users should not apply the workaround to continue using their Storpool
89-
storage.
90-
91-
This issue will be fixed in the upcoming CloudStack version 4.17.1.0.

97-
========================
98-
99-

100-
with 4.16 release the legacy UI has been removed. Users are encouraged to
101-
implement a migration path in their production environments.
