I am new to gluster and I am evaluating using it for a project. One of the things I am looking at is various failure scenarios and how gluster deals with them.
As far as I can tell, gluster is supposed to recover from a hung filesystem brick. I see that storage.health-check-interval is set to 30 sec by default and that this is supposed to detect a hung filesystem and recover.
My attempt to test this was to create a 1x2 replicated volume with XFS bricks, and then "hang" one of the bricks by executing xfs_freeze on it.
But, if I attempt to modify the volume, the client hangs forever.
Would this method be appropriate to simulate a hung filesystem?
Or is there something else I need to enable in gluster-3.7.4
