Accidentally interrupted sg_format any way to fix the drive? (520 to 512)

[Laguz]

Edit: Update i ended up finding another tool to use and that worked just fine

Code:

# camcontrol cmd da11 -v -c "15 10 0 0 v:i1 0" 12 -o 12 "0 0 0 8 0 0:i3 0 v:i3" 512
# camcontrol format da11 -q -y
# camcontrl format da11 -r to check the progress on web shell          

I purchased four SAS drives after receiving them i discovered they where 520 sector size and attempted to format the first drive to 512.

The command I used that got interrupted was

Code:

sg_format --verbose --format --size=512 --six /dev/da8

After which da8 shows 1KiB of space and fails smart scans and diskinfo checks "medium format corrupted"

Is there any way to recover from this or did i brick the drive? I have 3 more drives of the exact same size and model if that is relevant at all.

Any help would be greatly appreciated

I had the same issue, interrupted three formats. Ouch. I got back from it by:
- Halting the system
- Powering it off and allowing the drives to spin down
- Powering it back on
- Here I was stuck - an sg_format told me I couldn't format the drive
- Be depressed and do something else
- Come back hours later and try again - format started and completed

I don't know whether I needed a few hours pause for the drive firmware to get out of its funk, and whether I even needed to power down. What I can say is that this worked and I have two drives formatted and the third formatting right now.

The key is to physically remove power to the drive - completely unplug it and let it sit there for a few seconds. If your system supports hotplug you can do it live; otherwise, power down, unplug the drive, let it sit, and then plug it back in.

Then just restart the command.

After power cycling the drive i did manage to get the diskinfo to work on the drive, and did the format command again it's still reporting 1KiB in size even after power cycling again.

steps i tried
1. power cycle drive
2. diskinfo -c reported 1Kib
3. attempted the format command again letting it fully complete, web gui showed 1KiB size
4. power cycle drive
5. diskinfo -c reported 1Kib size again

Code:

root@freenas[~]# diskinfo -c /dev/da8
/dev/da8
        512             # sectorsize
        1024            # mediasize in bytes (1.0K)
        2               # mediasize in sectors
        0               # stripesize
        0               # stripeoffset
        0               # Cylinders according to firmware.
        64              # Heads according to firmware.
        32              # Sectors according to firmware.
        SEAGATE DKS2C-H2R0SS    # Disk descr.
        9WM7YBCF000092112YAZ    # Disk ident.
        id1,enc@n50050cc1020161c5/ty

from that it looks like the firmware got corrupted when the format first failed?

one of the drives i haven't tried to format yet out of fear of repeating the issue report

Code:

root@freenas[~]# diskinfo -c /dev/da9
/dev/da9
        520             # sectorsize
        1988629626880   # mediasize in bytes (1.8T)
        3824287744      # mediasize in sectors
        0               # stripesize
        0               # stripeoffset
        238050          # Cylinders according to firmware.
        255             # Heads according to firmware.
        63              # Sectors according to firmware.

Hi,

I have a similar issue I am currently using truenas scale on a Dell 730XD and I accidentally started to format one of drives in my zpool, I halted it tried rebooting, That didn't work I tried just unplugging the drives still doesn't work. when I check IPMI the drives are showing up as blocked on the HBA but they did showed up a ready before. If I try lsblk I do not see the drives. currently I do not have the server setup on a network with internet access, so I can't use anything that doesn't come with Scale. I am racking my brain trying to figure out how to go about fixing it. Can any one help?
