Hi,

There have been a few suggestions around "touch /forcefsck" and passing flags to shutdown. But these don't work after the SAN horse has bolted and the file system is read-only. Since a system with a read-only disk is generally unusable, as part of our build procedures we change the fstab mount option from onerror=readonly to onerror=panic. In the event of a SAN error, affected VMs reboot and because the file system wasn't cleanly unmounted, it gets checked on the way back up. This is all just sticking plaster, of course, but at least it's automatic.

Jonathan.
