    re-raid linux server

    We have replaced sda H.D.D for bad sectors.
    Now we have a free (non-partition) hda and sdb with software raid1.
    How can load all data located on mirro disk (sdb)?

    If sda was removed you should have an sda still instead of sdb as there is only one SCSI HDD attached.

    You just need to copy the partition layouts then you can rebuild like this

    mdadm --manage /dev/md0 --add /dev/hda1 (Example)

    Probably best an admin rebuilds it for you quickly if you are not sure.

    Thank you.
    I need to mount software raid1 partition in rescue mode

    I have:
    [[email protected] /]# mount /dev/sdb3 /root/old-disk -t ext3
    mount: /dev/sdb3 already mounted or /root/old-disk busy

    And is not mounted!
    Where is problem now?

    If you are running linux software RAID you shouldnt try to mount partitions like that.

    You need to mount raid devices.

    To view them run:

    cat /proc/mdstat

    + You do not need to use rescue mode to rebuild software RAID. Its a 5 minute job.
