[LU-2605] reduce the failover time when the MDS and OSS are on the same machine in High Availability

• Type: Improvement
• Resolution: Duplicate
• Priority: Trivial
• Affects Version/s: Lustre 2.1.0
• Labels: server
• Environment: Linux, 2 physical servers,; the 1st holds the active MDS and an active OSS and the 2nd holds the passive MDS and an active OSS
• Assignee: WC Triage
• Reporter: gmsw

Description

In case of failure of the 1st server, the MDS1 and the OSS1 will fail in the same time.

Then the failover on the 2nd node will wait 5 more minutes because the moved OST will wait the timeout for the failed client MDS1.

This case of 2 servers with failover and 2 active OSS is important for little configurations.
