Hi list,
If somehow, glusterfs client fuse process dies. All subsequent file
operations will be failed with error 'no connection'.
I am curious if the only way to recover is umount and mount again?
Yes, this is pretty much the case with all fuse based file systems. You
can use -o auto_unmount (https://review.gluster.org/#/c/17230/) to
automatically cleanup and not having to manually unmount.
If so, that means all processes working on top of glusterfs have to
close files, which sometimes is hard to be acceptable.
There is
https://research.cs.wisc.edu/wind/Publications/refuse-eurosys11.html,
which claims to provide a framework for transparent failovers. I can't
find any publicly available code though.

Thanks,
