what is (jail-name)-7tcfz ?

[picarica]

soo i recently noticed i have some vdev called Jellyfin-7tcfz its volume it has 10GB of space allocated and i have not idea how it was created, i have jail called Jellyfin, but why did it create this vdev? when i find in bash it only finds that vdev in /dev/zvol/NAS/Jellyfin-7tcfz and nothing else, i cant look what 10gb is it using?

can i safely delete it ? or how can i find out why its there and whats in it

Vdev? Or Zvol?

A pool is comprised of vdevs, so I don't understand how a vdev can materialize out of nowhere.


Do you see anything listed in your pool's dataset/zvol hiearchy?

Code:

zfs list -t filesystem,volume -r -o space,type poolname

hello as i said its a vdev, and yes i am confused as you are, here is the output of the command you askes for, i have no idea how it was created, the 4 random letter tells me iot was randomly generated but what generated it ? the jellyfin jail is manually made i made it ,but no 10GB vdev for it

I have two like that. Each one is the zvol associated with the virtual disk for a VM

 

[winnielinnie]

hello as i said its a vdev

That’s not a vdev; it’s a zvol. Your output shows this.

Like @NugentS said, did you use or play with a VM at any point?

i am posisitve i neved had any VM running or setup, if thats just debris from VM it should be safe to delete right ?

 

[winnielinnie]

If you're certain you don't need it and that it contains no important data within, then it's safe to assume you can delete it.

That's up to you.
