Ah yes. Never having used the recovery cd I would first look to see if the filesystem that /dev is on can even be written to. what does mount show? If you think that the original / file system is in place then you could probably chroot to the original fs and then be jammin chroot /mnt/sysimage/whatever should do it or use the device that is at /mnt/sysimage/whateveristheroot/dev/st0 as the device try mt -f /mnt/sysimage/whateverisrootfs/dev/st0 status Bret -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://www.redhat.com/mailman/listinfo/redhat-list
