Scott, Not sure if it works with GFS (I would assume so, but I don't have it installed to test) But normally you would run the following to remount an already mounted filesystem in read only mode: mount -o remount,ro <mountpoint> And conversely to remount read-write: mount -o remount,rw <mountpoint> Thanks, Eric On Mon, 2007-11-26 at 14:05 -0800, Scott Becker wrote: > I had a failure once where the kernel detected an inconsistency in the > file system and mounted it read only.
