Hello, I have technical systems knowledge but I am very new to TrueNAS.
tl;dr Ran "sg_format -v -F /dev/sdX" on two HGST 8TB drives, neither drive is usable. Did I brick them?
Sequence of events are as follows
tl;dr Ran "sg_format -v -F /dev/sdX" on two HGST 8TB drives, neither drive is usable. Did I brick them?
Sequence of events are as follows
- I purchased some stupid cheap SAS HGST 8TB drives from ebay and loaded 10 into my R730xd
- Installed TrueNAS Core, and created a 2x5 mirrored vdev pool. Storage looks great so far.
- Discovered I really wanted TrueNAS scale and migrated to TrueNAS-SCALE-23.10.0.1
- Pool was still there but saw alerts like "Disk(s): sdc are formatted with Data Integrity Feature (DIF) which is unsupported." To whit

To format use '--format'. To resize use '--resize'
- Didn't have any data in the pool yet so I deleted it and tried to re-created it... which didn't work. Menu refused to add any DIF enabled drives into a pool.
- Following a thread on this forum, I tried "sg_format -v -F /dev/sdX". The command is increadibly slow and probably got 0.5% in before the shell closed from auto-logout after 5min (that's on me)
- Now the disk is not reachable
- Tried the command again on a second disk, this time in tmux. Ran for several hours until crashing out at 17%. This drive is no longer reachable either.

^ interesting that the kernel logs mention disabling DIF before attaching SCSI... - Hot either of the "bricked" drives
