Do you mean mount the filesystems read-only? If so, this is the command to run: # mount -o remount,ro <filesystem> You will probably have to use lsof to make sure no processes are running on that filesystem. Another way to do this is if you are backing up a major filesystem (like / or /usr) is just to go down to single-user mode, do the backup, and bring it back up to the default run-level (3 or 5, generally). --=20 -- Skylar Thompson (skylar@attglobal.net) --AGZzQgpsuUlWC1xT Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (GNU/Linux) Comment: For info see http://www.gnupg.org iD8DBQE9Kx8CYyzijMrwBxERAiuLAJoCq7N+Ma3XhmPjj+c6gmQahoTSwwCePWZx bJnb+9JE7sKUfD43cLoZGgw= =WRBc -----END PGP SIGNATURE----- --AGZzQgpsuUlWC1xT--
