Hi There Experts,

I have a server dell power edge 2800 configured with 6 hard drives, 2 in span 0, 2  in span 1 and two in span 3.

in each span one hard disk fails , do you have any idea how to fix it. i am trying to unplug and plug again but that does not work, the rebuilding process fails,

I have no experience with raid 0 while have worked with Raid 5.

    RAID 0 has no redundancy:
    Reconstruction is not possible, you must to recreate volume and restore from backup.

    Assisted Solution

    As mentioned above, RAID 0 isn't redundant and if a disk fails you have lost ALL your data. You can't rebuild RAID 0 arrays. There is a tool (the RAID reconstructor) you can use that might be able to recover your data, but only if you are very lucky and if you haven't tried to do anything up to then that writes anything to the disks:

    So what I suggest you do now is to setup RAID 10 rather than RAID 0 (RAID 10 is redundant and as fast as RAID 0, but you loose half your capacity), then reinstall your OS and restore the data from your backups.

    There is no way to create good data out of thin air.  Your only hope is to use software such as the, or create a full bootable backup, and migrate the data to something with redundancy.

    The answers from the experts are all correct.  Bottom line, you can't fix this. Data has been lost forever.

    All experts basically said, "you can't do that". I was just more blunt and didn't sugar coat it.  Points should be spilt equally among the experts.
