[LU-12638] lsnapshot ignores failover host in ldev.conf

• Type: Bug
• Resolution: Fixed
• Priority: Critical
• Fix Version/s: Upstream, Lustre 2.16.0
• Affects Version/s: Lustre 2.13.0

• Severity: 3

Description

ldev.conf lists the failover pair for hosts, but it ignores that failover host.

lsnapshot should check for the zpool being imported on one of the hosts and then try to mount the snapshot on that host.

The current code tries to import the pool and mount the snapshot on the first listed host, which could fail if the pool is failed to the second host.
