[LU-4582] After failing over Lustre MGS node to the secondary, client mount fails with -5

• Type: Bug
• Resolution: Fixed
• Priority: Major
• Affects Version/s: Lustre 2.1.0, Lustre 2.2.0, Lustre 2.3.0, Lustre 2.4.0
• Labels: patch
• Severity: 3
• Assignee: Cliff White (Inactive)
• Reporter: Cheng Shao (Inactive)

Description

Following are steps to reproduce the issue reliably:

1. adjust obd_timeout from default 100 to 300
    lctl conf_param <fsname>.sys.timeout=300
2. mount and umount the client
    mount - lustre <primary MGS ip>:<secondary MGS ip>:/<fsname> /mnt/lustre
3. failover the MGS node to the secondary
4. mount the client again using the same command as in step 2

Then step 4 will fail with EIO.
