Hello all, All the previous postings about moving one's root file system has been very useful. I'm trying to set up RAID on my new SMP box. I've solved a number of problems: how to autodetect RAID devices, added the missing raid modules to initrd, etc. My RAID devices are now autodetected and started on boot. So I copied my / partition, ran lilo, etc. as follows: mount /dev/md0 /mnt/raid tar --one-file-system -cf - / | tar -C /mnt/raid -xvf - changed /mnt/raid/etc/lilo.conf -> root=/dev/md0 changed /mnt/raid/etc/fstab -> /dev/md0 / .... mounted my boot partition under /mnt/raid/boot lilo -r /mnt/raid -C /etc/lilo.conf This appears to have worked correctly, as upon reboot /dev/md0 is correctly autodetected and started, I get: fsck: /dev/md0: clean ... rc.sysinit: Checking root filesystem succeeded rc.sysinit: Remounting root file-system in read-write mode succeeded ohter file systems (not yet raid) successfully mounted then: atd[xxx]: Error redirecting I/O: Permission denied atd: atd startup failed Then, if in runlevel 5: X starts to come up, flashes, fails, and then repeats this indefinitely. I can't switch virtual terminals, but I can telnet in. df shows that /dev/md0 is mounted as /, attempting to run atd logs the same error. Upon shutting down, I get: xfs: shutdown failed atd: shutdown failed The permission denied for atd is perplexing. I poked around a little, and tried changing permissions on /dev/md0 to match other filesystem devices (ie group -> disk and permissions to 640), but got the same result. I'm guessing that if I can solve the atd permission denied problem, that the X problem will go away also. Did I screw up the options on the tar copy? Everything appears to be correct, w/correct permissions, etc. Device files must be OK, or I wouldn't have gotten this far... Any ideas? BTW, I am running RH6.0, updated with most of the RedHat updates (except Netscape and Gnome). Thus I am running the RH 2.2.5-22smp kernel, which upgraded fine. I did all the neccessary mkinitrd and lilo stuff, and the system boots fine with a non-RAID / partition.
