unable to auto mount /dev/md0 RAID 1


I'm having trouble getting my RAID array to automount. I know that the array is working OK since I can manually mount and unmount the RAID array.

I manually created the raidtab file, made an entry into the fstab file and still cannot get it to auto mount upon reboots. The following is info someone may need to point me in the right direction.

/etc/fstab
# This file is edited by fstab-sync - see 'man fstab-sync' for details
/dev/VolGroup00/LogVol00 / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
none /dev/pts devpts gid=5,mode=620 0 0
none /dev/shm tmpfs defaults 0 0
none /proc proc defaults 0 0
none /sys sysfs defaults 0 0
/dev/md0 /devhome2 ext3 defaults 1 2
/dev/VolGroup00/LogVol01 swap swap defaults 0 0

/etc/raidtab

raiddev /dev/md0
raid-level 1
nr-raid-disks 2
nr-spare-disks 0
persistent-superblock 1
device /dev/hdb1
raid-disk 0
device /dev/hdd1
raid-disk 1

The RAID1 array is going to be used to store data the /devhome2 directory. I'm sure that I'm missing something. I would appreciate any help or advice.

Code:
/dev/md0 /devhome2 ext3 defaults 1 2
Should it be /dev/home2 ?

Thanks for your reply EW. Nope. I'm using a directory called devhome2. The original sysadmin that setup the server liked this name.

I tried other variations of the last two columns in fstab such as 0 0, and 1 1. No go.

I'm still scratching my head on this one. I can't understand why when the RAID 1 array is setup manually using mdadm, I cannot get the server to auto mount the md0 array to /devhome2. Please note that I can mount the md0 array manually to /devhome2.

more info:
uname -rs
Linux 2.6.9-1.667

Help!

did you set the partition type of the raid-members to FD (raid auto detect) ?

Are you specifying the filetype when you mount it manually? Is it possible that it's not actually ext3? Mount it and then run "mount" to check.
