How to avoid fscks caused by "device busy" at reboot time.

[Aby]

If you often get device busy errors on shutdown that leave the filesystem in need of an fsck upon reboot, here is a simple fix:

Code: [Select]

To /etc/rc.d/init.d/halt or /etc/rc.d/rc.0, add the line
mount -o remount,ro /mount.dir
for all your mounted filesystems except /, before the call to umount -a. This means if, for some reason, shutdown fails to kill all processes and umount the disks they will still be clean on reboot. Saves a lot of time at reboot.
