Thanks for suggestion.
I've tried this but the server is back up in a few seconds, so I am  
fairly certain it isn't running a fsck at boot time after issuing  
"reboot".

And the only half helpful suggestion from the hosting was running in  
single mode from grub, but the disk is mounted at that time. Else to  
rollback a snapshot of the server which would mean hours of  
reconfiguration which I am hoping to avoid.
