Default timeout is 108 seconds. If you are using afr between Server A and B,
Command completes successfully even if ethernet cable is unplugged from
server A.

Just AFR alone can provide high availability here.

Can you send the glusterfs Specification files? Do you need both the
functionalities of AFR and unify or just high availability (AFR by itself
can provide high availability).

A centipede was happy quite, until a toad in fun,
Said, "Prey, which leg comes after which?",
This raised his doubts to such a pitch,
He fell flat into the ditch,
Not knowing how to run.
