How to Delete Drive That is Missing From a RAID I had a RAID drive fail. I replaced the bad drive with a new one and, after some work, got it up and running. I want to delete the bad drive from the config. This is the latest listing:

I just noticed when pasting this, the status is still degraded. When I tried to remove it I got this error:

@ Yamadoshi (curt)| =&gt; sudo diskutil appleraid remove 1BAC60DD-CA77-444D-B4C4-BDAB73248240
Password:
Usage:  diskutil appleRAID remove MemberDeviceName|MemberUUID
    RAIDSetVolumePath|RAIDSetDeviceName|RAIDSetUUID
Remove a member or spare from an existing RAID set.
Ownership of the affected disks is required.
Example: diskutil AppleRAID remove disk2s4 /Volumes/RAID
     diskutil AppleRAID remove 11111111-2222-3333-4444-555555555555 disk5


How do I get rid of the missing drive? Do I have some other problem given the Degraded status?
The answer is, that you have to add the path to the Mounted volume at the end instead of the disk number. For example:

diskutil AppleRAID remove 11111111-2222-3333-4444-555555555555 /Volumes/MYMOUNTEDDISK/
