Indeed - my problem was that I didn't include the -V size definition. By
default ZFS accepted the pool at the maximum size, but wouldn't populate
the devices. Interesting.

I did

#zfs create tank0/xcp

Seems that indeed when I specified a -V with a volume size it worked
correctly.

Let me check my lun export with the newly populating /dev/zd0 device now
that I've created it with a -V flag.

I've been runing ZFS on Debian for a couple months, and never had either of
those either, until I created a fix size volume with "zfs create -V 100G
backups/vbox/zvol".

----- Begin before -----
0 > ls -lF /dev/zd* /dev/zvol/
ls: cannot access /dev/zd*: No such file or directory
ls: cannot access /dev/zvol/: No such file or directory
----- End before -----

0 > sudo zfs create -V 100G backups/vbox/zvol

----- Begin after -----
0 > ls -lF /dev/zd* /dev/zvol/
brw-rw---T 1 root disk 230, 0 Jun 22 16:28 /dev/zd0

/dev/zvol/:
total 0
drwxr-xr-x 3 root root 60 Jun 22 16:28 backups/
----- End after -----

Have you created the zvol's yet?
