Disks in RAID "Offline" - won't mount
I can't get my mirrored RAID 1 array to mount. This comes after a forced shutdown. These are external firewire disks, daisy-chained, and hooked up to a G4's firewire port.
The drives power up fine, show up in Disk Utility, and even spin up when I click the "Mount" button, but they never show up on the desktop.
I tried to verify the array, and I got this error message:
Verifying volume “Acomdata RAID”
Checking HFS Plus volume.
Invalid key length
Invalid key length
Catalog file entry not found for extent
The volume needs to be repaired.
Error: The underlying task reported failure on exit
I click the "Mount" button, and the log says: "Mount of “Acomdata RAID” succeeded", but the Disk Utility window still shows the disk as Unmounted, and it never shows up on my desktop.
I've tried starting up the computer with disks already turned on, and also turning them on after the computer fully boots.
I tried booting from a Panther disk, and from a Tiger disk, and running Disk Utility from there. Panther doesn't even see it, and Tiger gives me the same error message. DiskWarrior sees the disk as "Unknown Disk".
The one clue I can find is in the RAID pane:
It shows the 2 RAID slices as "Offline", but I can't find anyway to put them online. Anyone have some ideas? Is this offline thing even matter?
