Something is keeping the volumes "open". (disks with mounted volumes have their partition maps write protected)

Connect to a different computer, or create a second startup volume on the Mac. (add a new volume to your internal with Disk Utility, start in recovery mode, reinstall MacOS and point the installer to the new volume. Do not migrate data, just use the same admin name)

Yes. All you need to do is slide the disks out an inch, so they lose electrical contact.

Since no volumes on these disks can mount, this will work.

Thank you, I was able to delete the volume.

However, when I try to create a new volume with the remaining space (2tb, Raid5, server, 16kb stripe, hfs+) it fails with the same message of disks being inaccessible, despite no apps running - nor SMB clients mounted.

Any suggestions?

Here is a brute force way, as someothing is hanging onto your volume or volumes.
shut down, disconnect your drives, and startup.

Pull our half the disks, then connect the drives. Delete the volume on those disks.

remove those disks, then connect the rest. Delete the volume.

(you only need to pull them out an inch)

Just making sure I follow:

1. Shutdown

2. Disconnect Thunderbay

3. Power back up.

4. Open enclosure - remove 3 disks ( d-f) so they are not seated in sata ports

5. connect enclosure

6. Delete the volume on disks a-c

7. Shutdown

8. Disconnect Thunderbay

9. power back up.

10. Open enclosure and remove disks a-c (physically?)

11. Re-seat disks D-F

12. Connect enclousure.

13. Delete volume on D-F

14. Shutdown, re-seat a-c, connect enclosure and power back on.

Sound right?

I have been unable to remove a softraid volume. I have tried stopping all applications, unmounting any volumes sharing disks, made sure time machine is not referencing the volume.

I can not pull a disk identifier / mount point via diskutil either. The volume is RAID5 using six disks for a 2 TB HFS+ data volume. It is empty. The disks are also used in an 18tb media storage volume - it is using 33% of its capacity.

It errors out with disk being accessed (no applications running) or FDA in privacy/secuity (un-enabled and re-enabled). The volume is unmountable.

I just want to mount the volume (and use) or delete and recreate.

Thank you.
