SOLVED removed geli encryption on my pools, but see swap0.eli and swap1.eli

[Guri89]

Hi everyone,

like the title said, I removed geli encryption from my 2 pools.
I did that following the guide found on the forums (https://www.truenas.com/community/t...om-a-zfs-volume-while-keeping-the-data.16467/)

worked great, and I do not have any .eli partitions in my pools anymore.

I was on the point to delete the geli keys, that I still have on disk in /data/geli
For good measures I did a geli status before, expecting an empty output, but to my surprise it's not

Code:

# geli status
            Name  Status  Components
mirror/swap0.eli  ACTIVE  mirror/swap0
mirror/swap1.eli  ACTIVE  mirror/swap1

Code:

# geli list

# swapinfo

/dev/mirror/swap0.eli   2097152        0  2097152     0%
/dev/mirror/swap1.eli   2097152        0  2097152     0%
Total             4194304        0  4194304     0%

I do not want anything geli-related on that box anymore
Any idea how I can get rid of those too?

Thanks

FreeNAS/TrueNAS automatically uses encryption on swap disks, and this is unrelated to any user-configured encryption you may have set up on your pools.

I never ever used encryption on my pools and look at the outpout that command gives me:

Code:

# geli status
            Name  Status  Components
mirror/swap0.eli  ACTIVE  mirror/swap0

ah ok, I had no idea
looks like I'm all set then

thanks a lot for the feedback!
