[ PCA ] NFS Issues After ZFS Takeover / Failback Cause OVM Manager to Become Unresponsive / to hang (Doc ID 2386073.1)

Last updated on MAY 26, 2021

Applies to:

Private Cloud Appliance - Version 2.3.1 to 2.3.3 [Release 2.0]
Linux x86-64
High Availability testing

Symptoms

After successful takeover/failback of a head on the ZFS storage system, the primary (active) Management Node was unable to access the nfs mount points on the active storage node.

 

All other computes nodes and the non-primary (passive) management node continued to be able to access the NFS mount points and files without issue.

Normal shutdown-reboot of the primary (active) management node did not complete. A "forced" reboot was required to fail-over the OVM Manager to the non-primary (passive) management node.

Changes

Newly-installed PCA 2.3.1 system undergoing "high availability" acceptance testing

As part of this, the active head of a zfs storage node was disabled to force takeover by the other head.
