don't mean to barge in, however I have seen similar corruption happen in
the past where the fabric went away momentarily, like unplugging and
replugging a fibre cable on a non-dualpath/failover setup but the host
was not killed/rebooted. From memory the corruption was not immediately
apparent and became so later.
I think the best thing to do in that case scenario is force a reboot of
the host and then force fsck as opposed to continuing on and hope for the
best.
