Unable to wipe disk

[Octopuss]

I have a weird problem.
I tried creating new pool with a bunch of new disks (will migrate data from the original pool later), but I keep getting this after clicking create pool:

Error: Traceback (most recent call last):

Any idea what's going on?
I'm on TrueNAS 12.0-U7.

P.S. Manually trying to wipe a disk give me "Error: [Errno 22] Invalid argument".

I thought it could be some garbage in the browser cache or something, but nothing. Restarting the server made no difference either.

Linux live CD or Windows diskpart/clean?

Are you certain they are 512b drives rather than 520, etc?

 

[Octopuss]

Live CD what?
These are SAS disks (4kn) I recently installed in the server and ran badblocks on. I aim to move the pool (not sure how yet) from the current WD Reds to these.
I wanted to create a new pool on them just to test things out, but came to this dead end.

Oh I forgot to mention. TruNAS is running under ESXi.

Can anyone tell me how to wipe/format/anything a disk from the shell? Maybe that would work since the interface code is bugged (that's the only conclusion I can come to when I see references to the source and errors).

Even more weird - I am no able to wipe disks from the storage part of the GUI... except for one. Well, to be specific, two of the four disks could be quick wiped without problems. The last one is doing a full wipe (according to the slow progress in the task manager) despite selecting quick, and the first one flat out refuses to work with Error: [Errno 1] Operation not permitted: '/dev/da4' error.
What's going on here?!!!!
Are there really no detailed logs anywhere? This tells me absolutely nothing :(

When I try to do gpart destroy -F da4, it returns "device not configured"

 

[Octopuss]

I formatted the disk from command line using
sudo sg_format --format -v /dev/da4
It went without problems, but trying to wipe it from the GUI gives me the "operation not permitted" error again.

No idea how to interpret this and why the other three unused disks aren't shown, and if this is even of any relevance.
Something seems to be selectively preventing me from performing certain actions on the disk. I don't get it.

Hm, I googled up this weird sysctl kern.geom.debugflags=16 command and that unblocked whatever it was and now it finally all works. Rebooted afterwards just in case.
Jesus.
I hate working with stuff I have absolutely zero knowledge about.
