ZFS partition empty on Linux pve

[fulco]

Hello

I'm with Proxmox VE 8.3.4
My ZFS storage was working fine, but I'd liked to reduce it because it took all the disks space, and I wanted a new partition
I copied files/vms, destroyed it, then created a new one with the same name
Now the new ZFS storage works fine (VMs run), but in cli on the server, the mounted partition is empty
I tried to destroy it again and create it with a different name, but there's the same issue
On this forum, I read that it's working for someone who had desactivated the automount at boot, and then mount it "manually" (by cron). But it doesn't work for me

Thank you in advance.

Hi
As I didn't found any solution, I've reintalled my server pve
But I get the same issue
I'm quite sure that ls+df was working before on the zfs partition on my server pve

Same problem here. All ZFS datastores work properly but all!!! their mounting points are empty and also show incorrect sizes and free bytes
Have also no idea why. I think this is a BUG in Proxmox VE ?

A `zfs list` would be interesting to know more. Please paste it in a code block (tools of the editor) to be readable.

All those sub-datasets are disk images for VMs right? Those are volume datasets (aka zvol). They are block devices and show up in /dev/zvol/{pool}/... as they are not regular files.

So from what I can tell, the output of zfs list looks as expected.
