    Hello again (after big server crash)

    i have taken a relook to my raid system.

    this is in fstab
    Code:
    proc            /proc           proc    defaults        0       0
    /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
    Code:
    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.
    The /proc/mdstat file currently contains the following
    Code:
    Personalities : [raid1] 
    read_ahead 1024 sectors
    md0 : active raid1 ide/host1/bus0/target0/lun0/part4[0]
          67633536 blocks [2/1] [U_]

    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.
