Hi, I'm trying to setup a Raid1 mirror between 2 hard drives. I have the following. 1- SDA 36gig System disk 2- SDB 36gig blank 3- SDC 36gig blank I'm trying to Mirror SDB to SDC by doing the following. 1- By using FDisk I created SDB1 and SDC1 on each drive. 2- I then makefs ext3 for each partition. 3- Then I used mkadm --create /dev/md0 --level=1 --raid-devices=2 /dev/sdb1 /dev/sdc1 I ran watch cat /proc/mdstat until the process was completed. 4- when it was complete I tested the mount using mount -t ext3 /dev/md0 /home/apps and it mounted and I was able to open it. 5- I then edited fstab with /dev/md0 /home/apps ext3 defaults 1 2 and rebooted. 6- I now get the following error at boot. FSCK.ext3 /dev/mdo the superblock could not be read or does not describe a correct EXT2 Filesystem.......bla bla and asks to run E2FSCK -B 8193 7- I used Vi and comented out the mount in fstab and re-booted. I tried to manually mount the drive the same way as (Item #4) and it now fails Mount: Wrong FS Type. Any ideas as to what I need to do. Sould I use ext3 ? thanks Marc -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
