impossible to wipe disk

[yaume]

Hi,

I can't wipe my 3 disks on freenas.
Each time, i obtain this message:
Error: Failed to wipe ada1: dd: /dev/ada1: Operation not permitted
Error: Failed to wipe ada1: dd: /dev/ada1: Operation not permitted

Error: Failed to wipe ada1: dd: /dev/ada1: Operation not permitted

What can i do to solve the problem.
I understand that there is some residu on the disks, but i've not found any solution.

Thanks.

I had the same error when I tried to do a dd random write to some disks. I'm thinking that FreeNAS is protecting the disk because there used to be a zpool on the disk. Somewhere here is a command that "unlocks" FreeNAS and allows you to overwrite the disks, but I can't remember it off the top of my head. I'll post back if I confirm/fix the issue.

 

[cyberjock]

Ok, I couldn't find the command line to allow you to dd overwrite the disk, but here's how I got around the issue. I wiped the disks from the GUI, chosing the "quick" wipe. This wipes out the zpool metadata. Then a reboot and I was able to dd write to the disk.

thanks,

Well, now i can't create a volume.
When i try "quick wipe", i ve the message "wipe successfull"
But if i choose "wipe with all to zero" i've an error.
when i try to create a volume i've an error.

i think freenas don't like that i've already use these disks before, and i've remove it from freenas and recreate.

 

[cyberjock]

Did you reboot? It's important that you reboot so FreeNAS doesn't protect the disks anymore.

 

[yaume]

Ok i've do a lot of things, so i could be clear now.
I've done what you do => quick wipe disk and reboot and it's working full.
What i don't understand is that it's not working if i do a full wipe disk with zero (or random).

Thanks for your solution.

Hi yaume,

How long are you waiting for the full wipe to complete?

Keep in mind a full wipe (especially with random) is going to take a (very) long time depending on how big the drives are!

I've got 3 drives of 1TB.

Yes, i understand that it's too long, but what i can see, the % bar stopped at 14% (or other value ,it's depend of the HDD) and says "error can't wipe disk" (something like that) and in the console i see something like GEOM.... and "operation not permitted"
I'm sorry i've not keep the message and now it's working with cyberjock's solution.

What i can say to you is that i've mounted these disks with freenas in UFS format. and unmounted, reset factory in freenas, and try to mount again the HDD in my new freenas (after the reset factory), that's the beginning of the problem.

I'm sorry, i'm very rooky with freenas.

Honestly, if you are more familiar with Windows, i'd use a windows program to wipe the disks. In FreeNAS, you seem to have a good grasp of it(the errors aren't helping you learn anything though). You can "monitor" the write and reads on the disk devices with the command gstat.

 

[yaume]

well, now with your solution it's working fully.
