Hello, i ended up buying some HDD’s from ebay and all the drives are showing up and everything but when i try to build a pool it says Data Integrity Feature (DIF) which is unsupported.
How do i go about getting this disabled and fixed so i can use the drives in TrueNAS
Full Error: sda, sdj, sdl, sdm, sdg, sdh, sdk are formatted with Data Integrity Feature (DIF) which is unsupported.

According to this article on reddit:
-
Run sg_format --format --size=512 /dev/sdx on each drive (you can run them in parallel if you use tmux - and they are long running so you need to use tmux anyway).
-
Power cycle your server.
I have 4 - 4tb SAS drives with this problem. I started a reformat about 4 hours ago and made the mistake of leaving the shell after it showed a couple of progress reports for fractions of a % done. Now there are no more progress reports.
How can I tell if the format is still running, complete or cancelled because I closed the shell. Dare I reboot before the format is complete?
How can I run the formatting of several drives in parallel?
Log into the TrueNAS Scale console. Run something like ‘top’ so you can see some action. Alt+F2 should bring up the second virt console. log in and run your second command. Alt+F1 gets you back to the first console where you should see ‘top’ running.
You should be able to do this with the commands for a disk in the separate console windows
Hello,
i had that same issue with one of them. so what i did is run the same command again to format it should give a error saying its busy if it does then its still going. and in there it should say to see more info put - something and that will show you the % its at

The command option is -v and the response is
admin@truenas[~]$ sudo sg_format --format -v /dev/sdb

It seems that the formatting continues even if I close the shell and reboot. It looks like a 4tb disk takes about 15-16 hours to format.
For info if you add the option --ffmt=1 it’s much faster.
sg_format --format --ffmt=1 --size=4096 /dev/sdx
I would also go 4Kn as most/all HDDs are 4K these days.
yeah so your is almost done give it 2 or 3 hours and it should be done
