Help getting UFS pool back in freenas 11

[coneill]

So I recently upgraded from 9.3 to 11 and my old pool with a single UFS drive isn't loading. I saw UFS is pretty much gone now in freenas 11. Ok no problem, Its just a single backup disk anyway. However I've spent the last 5 hours trying to import the single disk back as a single drive ZFS but I keep getting these errors every time I try to create a new pool with it.

Code:

Ive tried getting rid of the first and last sectors

Code:

dd of=/dev/zero if=/dev/ada1 count=100
dd of=/dev/zero if=/dev/ada1 count=100 seek=39007029067
 

because I read of the drive hanging onto the GPT partitions but that doesn't seem to work. I've tried doing

Code:

gpart destroy -F /dev/ada1

but then I get an error that the device is busy. I've also tried

Code:

swapoff -a

and then all of the above but that also doesn't let me create a new pool with this disk.

UFS is not supported in modern versions of FreeNAS. It has not been supported for several years. I don't know what you are trying to accomplish with all those commands. Are you trying to destroy your data?
If you want to wipe the disk and create a ZFS pool on it, you do that from the GUI.

understood that UFS is no longer supported. I used this UFS disk in Freenas9 to do local backups so I wanted to turn it into a ZFS pool in FreeNAS 11 to keep doing local backups to it. When I wasn't able to create the pool at first in the GUI I saw some posts on here with something about old drives from another FreeNAS install keeping information on some sectors of the disk so I figured I'd just wipe the disk so it was clean and then like you said use the GUI to create a new pool and then just rsync all my data back to it. But every step of the way the using GUI generates an error. Last night I let the Wipe -> Full with Zeros command run from the GUI on the disk and still this morning I can't create a pool with it. I keep getting the same error messages every time that I posted above no matter what I try to do to make the disk look "clean" to FreeNAS

If there is any additional information I can provide Id be happy to.
