    THIS IS COPIED FROM ANOTHER AREA OF THIS SITE

    I am running OS 10.3.5 on a plain G5 with external FW800 LaCie twin 305GB drives as RAID 1. After a freeze I had to shut down the machine and on restart got an unrecognixzable disk in the RAID array, so shut the machine down and went to bed.

    This morning it boots fine and DiskUtility shows the RAID array with both disks degraded.

    But…I checked the Raid status with terminal as suggested in

    http://docs.info.apple.com/article.html?artnum=106987

    and it says both disks have status OK

    Name: Hydra
    Unique ID: Hydrab2e9e566214a11d99823000a95afef40
    Type: Mirror
    Status: Degraded
    Device Node: disk6
    ————————————————————-
    # Device Node Status
    ————————————————————-
    0 disk5 OK
    1 disk2 OK
    ————————————————————-

    I also ran Disk Warrior to rebuild the directory and ran repair in Disk Utilities and they checked out OK

    Is it possible there isn’t a problem? or if not how would I find a problem?

    Apple notes that with the OS X Server it is possible to ignore the degraded status in some cases, implying it might be mistakenly reported

    anyone ever heard of this? any suggestions

    thanks

    ps I also note that the disk is journalled and diskutil implies the journal is overflowed

    disktuil info disk6
