Can't format disks

Featured Replies

I have 5 x Samsung 990 PROs in a Terramaster F8 SSD Plus, but I can't seem to format the disks. I can add to a pool, start an array (empty), and select format, but then nothing happens (it's says "Started formatting" but doesn't do anything).

 

A couple of commands I entered, and diagnostics attached:

 

fdisk -l /dev/nvme0n1
The backup GPT table is corrupt, but the primary appears OK, so that will be used.
Disk /dev/nvme0n1: 3.64 TiB, 4000787030016 bytes, 7814037168 sectors
Disk model: Samsung SSD 990 PRO with Heatsink 4TB   
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: gpt
Disk identifier: 9CB959A0-26DB-4609-B75D-5D8A469614C4

Device         Start        End    Sectors  Size Type
/dev/nvme0n1p1  2048 7814037134 7814035087  3.6T Linux filesystem

 

and

 

blkdiscard -f /dev/nvme0n1

blkdiscard: Operation forced, data will be lost!
blkdiscard: BLKDISCARD: /dev/nvme0n1 ioctl failed: No data available

 

I took the drives from a QNAP, in case they are locked somehow?

 

My plan is to put these all into a single raidz1 or z2 pool, and maybe expand later.

 

Any help much appreciated!

Do you have a different NVMe device you could test with?

No, but I think I may have resolved it. I'll confirm once everything is up and running. Success!

 

In short, I had to erase/unlock the disks using their PSIDs.

 

I used sedutil-cli. I couldn't get it working on unraid so put the RESCUE64.img.gz image on a USB stick (using balena etcher) and booted that, then used the following command for each disk:

 

sedutil-cli --yesIreallywanttoERASEALLmydatausingthePSID <PSIDALLCAPSNODASHES> /dev/<disk>
