Hey Guys,

My raid does not seem to mount while booting up.

I`m running redhat 4 and I have created a raid5 device /dev/md0 using mdadm tool

I can see the raid details when I type:
mdadm –detail /dev/md0 and everything looks perfect

I can even mount it :
mount /dev/md0 /mnt/raid5

And it mounts just fine
I can go into the /mnt/raid5 and see the lost+found directory and create files there

And I have added this line to the fstab file:
/dev/md0 /mnt/raid5 auto default 0 0

But it doesn’t see to be mounted when the system reboots, I get an error in the boot.log

Nov 17 16:49:53 gdongg rc.sysinit: Checking filesystems succeeded
Nov 17 16:49:54 gdongg mount: /dev/md0: Invalid argument
Nov 17 16:49:54 gdongg mount: mount: /dev/md0: can't read superblock


Can anyone help please!!!!!!

Thanks in advance!
