    Ok, so there’s a strange issue here… On our XServe we’ve got a storage volume aptly called “storage” It’s a RAID partition made up from disk1 and disk2. The raid volume shows as virtual drive disk3. Now, after looking at the server monitor program I noticed that the RAID status is shown as “degraded.” I’m guessing this has something to do with the volume filling up due to a slightly embarrassing oversight. Anyway, the problem is, neither of the slices are seen to be damaged in any way when I do a “sudo diskutil checkRAID.” They both come up as “OK.” So, I’m not sure which is out of sync or whether either are out of sync. Therefore I’m not sure what to do to rebuild the mirror. Any suggestions?

    Thanks,
    Brian

    I’m running panther on the server. I found out something interesting, though. When I looked at both of the drives via server monitor, it noted that the amount of data transferred to and from one of the drives was lower than the other, so I’m guessing that the one that has a higher amount of data transferred back and forth is the drive that’s currently functioning, therefore the drive that I want to repair from.

    Currently,

    disk3 == virtual drive
    slice 0 == disk2
    slice 1 == disk1 – the current funtional drive

    So, I’m thinking that the correct command to repair the mirror would be:

    diskutil repairmirror disk3 0 disk1 disk2

    Do I get a cookie?
