[BlueOnyx:09067] Read-only /tmp

[Robert Fitzpatrick]

Found on a BO 5106 server that the /tmp filesystem is read-only, not
sure why. I tried to remount and it say write-protected. I compared /tmp
permissions to another working machine, both the same. I tried to fsck
and it warns of severe damage if mounted, I try to unmount and it is busy...

Is the only option to reboot?
