You can mount an ext3 FS as ext2; no problem. The kernel will simply ignore the journal, and the FS will behave exactly as it was before under ext2. That's the beauty of the system. You can go back and forth between the two systems. If you want to permanently go back from ext3 to ext2, then you have to use tune2fs to remove the journal (although it is safe to leave it there even if using the system as ext2). -- Anand Buddhdev Personal site: http://anand.org _______________________________________________ Redhat-list mailing list [EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/redhat-list
