/dev/hde1 / ext3 defaults,errors=remount-ro,usrquota,grpquota 0 1
/dev/hdc2 /boot ext3 defaults 0 2
/dev/md0 /var ext3 defaults 0 2
/dev/hdc3 none swap sw 0 0
/dev/hda /media/cdrom0 iso9660 ro,user,noauto 0 0
this is when i run mdam
server:~# mdadm /dev/md1
/dev/md1: 72.64GiB raid1 2 devices, 1 spare. Use mdadm --detail for more detail.
server:~# mdadm /dev/md0
/dev/md0: 64.50GiB raid1 2 devices, 0 spares. Use mdadm --detail for more detail.

WoW my server is more f*cked up then i tought :s

[ghys]

thanks for the great links. Very good info in them.
I am still looking for the best all around solution for the system i have to setup.

Either Raid 1 with a spare drive to backup or Raid 5.
I will not duplicate posts since i already asked something in here(another thread).
I will continue looking for the right answer.

thanks again.
