Re: how to fsck

["Brad Brad" <braddeicide@xxxxxxxxxxx>]

Hi, thanks for the reply.  Actually my loops are set on startup with an init 
script, so my fstab is plain except it uses /dev/loop2 instead of /dev/md0.  
I can happly mount and unmount it like an unencrypted drive.

If i start the system and log in as root, mount the partition, sync, is it 
ok to do a fsck on a mounted fs as no files are open?

This problem is most probably caused because the drives are never unmounted 
when the system shuts down, their always "busy" at the time.  I can prob fix 
that by looking into the shutdown script.s
