Symptoms

Node may unexpectedly reboot upon creating snapshots or using Data Protection functionalities using snapshots on a non-affined node.

Cause

Snapshot creation is done in a round robin manner (Node-a and then Node-b and so on). If the snapshot is being created on a node that does not own the volume, in extreme cases, it may lead to a cache locking fairness issue and a node reboot. 

This issue only occurs during the snapshot creation.

Resolution

This issue is fixed in PowerStoreOS 3.5.0 and above.
Upgrade to the latest PowerStoreOS 3.5.0 or above release.


If upgrade to PowerStoreOS 3.5 is not possible, escalate to Global Services for assistance and workaround.
