On our virtualisation infrastructure we have a 4To GFS2 over a SAN.

Since one or two weeks we are facing read I/O issues, 5k or 6k IOPS with
an average block size of 5kB.

I'm looking for the possibilities and didn't find anything yet, so my

    Is it possible that reaching over 80% use of the GFS2 can produce
    such workload?
