Error 144 create CT

[lilphoenix]

Hello
After a clean reinstall of Debian on ZFS root and reinstall Proxmox, when I created a CT, I've : Formatting '/var/lib/vz/images/100/vm-100-disk-3.raw', fmt=raw size=8589934592 mke2fs 1.43.4 (31-Jan-2017) Discarding device blocks: 4096/2097152 done Creating filesystem with 2097152 4k blocks and 524288 inodes Filesystem UUID: c9c9004a-f099-4304-b7a5-771cabb25dfb Superblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632 Allocating group tables: 0/64 done Writing inode tables: 0/64 done Creating journal (16384 blocks): done Multiple mount protection is enabled with update interval 5 seconds.

I just use right now my SSD as a zfs pool. Following the tuto on Debian Stretch on Zfs root https://github.com/zfsonlinux/zfs/wiki/Debian-Stretch-Root-on-ZFS. And after tuto Proxmox on Debian Stretch https://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_Stretch. At the end, I
zfs create rpool/VMDATA

You need to create a ZFS storage entry for your rpool/VMDATA (Datacenter/Storage).

Ok, thanks, I create my ZFS storage, and after need to create CT by cmd not by GUI (I've error).
But how snapshot my new CT? snapshot button is not available.

What error do you talk about?

 

[lilphoenix]

TASK ERROR: cannot open directory //rpool: No such file or directory
So I can't create CT by GUI and can't make snapshot by GUI also.

I don't know how create it

You should add a 'ZFS' type storage (not a directory storage).

 

[lilphoenix]

It's what I done : DataCenter => Storage => Add => ZFS

 

[dietmar]

Please can you post your storage configuration (/etc/pve/storage.cfg)?

"You should add a 'ZFS' type storage (not a directory storage)."

This Fixed the issue for me.

My ZFS dataset had no mountpoint when I configured the proxmox storage. After setting the mount point I had to re-create the proxmox storage to get it to work.
