Hello,
I'm prototyping the ZFS-over-iSCSI functionality on PVE 9.2.20 and running into trouble. Specifically, I followed these two blogposts to get it set up (I added auth on tpg1 instead of the ACLs).
PVE package list:
targetcli setup:
storage.cfg:
Added to /etc/iscsi/iscsid.conf:
iscsiadm discovery shows one entry. Login is successful.
Proxmox is able to SSH in and I see the ZVOL being created in the pool, but VM creation fails with
What am I doing wrong?
Thanks in advance!
