Thanks, Gang
It is a very large file system - around 600TB.
Could this be why it takes around 5 - 10mins to do journal recovery?
What we do as a workaround is -
- Disable the filesystem resource on startup
- Manually mount it (wait for as long as it takes)
- Then umount it
- Enable filesystem resource
But this doesn't seem like the right approach.
We have tried repairing the Filesystem when a failover happens, but it
has never shown any major corruption.

Indivar Nair

Usually, file system must do the log recovery during the file system is mounted.

File system introduces a journal to avoiding take too long time for file system recovery.
If the time is too long, maybe this is a file system problem, e.g. file system is damaged.
Secondly, you can set the timeout value longer.
