I followed your advice and was able to make a file system on /dev/mdo. I enter this entry in fstab /dev/md0 /home/apps ext3 defaults 1 2 I tried ext2 and ext3 and got the same error after re-booting.this happens when Checking file system runs " The superblock could not be read or does not describe a valid ext2 file system/. the odd thing is that as soon as I create the file system on /dev/md0, I can mount it using mount -t ext3 /dev/md0 /home/apps. I can go in and see the lost and found folder. it only fails after a re-boot. Also if I remove the mdo entry in fstab, reboot and try mounting it manually, it now fails (invalid file system) thanks Marc On Fri, 2006-01-27 at 13:30 -0500, Frank DiPrete wrote: > Check the order here: > > 1) create physical partitions on sdb and sdc of type linux raid > 2) create the (soft) raid array > 3) mkfs on the raid device created in step 2 > 4) mount the file system created in step 3 > > -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
