ZFS over iSCSI: VM-creation fails

[shh]

Hello,
I't trying to get ZFS-over-iSCSI running. Proxmox 8.2.4, all (free) updates.
All seems to be setup correctly, however when I start the VM creation it fails:

stopped: unable to create VM 100 - Could not open /dev/data/iscsi/vm-100-disk-0

But, the zvol was created correctly in /dev/zvol/data/iscsi/vm-100-disk-0
and Proxmox is searching at the wrong place: My system doesn't have a /dev/data/ path!

/etc/pve/storage.cfg
...

rpool/var-lib-vz          3.26G   172G  3.26G  /var/lib/vz

Any ideas why Proxmox is using a wrong path for the zvol?
And how I can correct this?

Best regards...

Try symlinking /dev/zvol/data to /dev/data. IIRC, this is a platform specific problem.

EDIT: May be a duplicate of this.

Yes!
Symlink helped, thanks! But this doesn't survive a reboot I guess.

- Proxmox 8.1.10: Same problem, no pool at /dev/
- Std-Debian with ZFS: no pools at /dev/
- Even Solaris/OmniOS doesn't link the pools to /dev/
This should be considered a bug.

This should be considered a bug.

It is and until it is solved, you may apply the udev fix.
