hi Tonci
in case you do not have time and small disks
you may create 3 ZFS mirrors
so there will be for example
rpool for PVE
ctpool for CT/QM
datapool for backups
e.g. in your case
rpool and ctpool may be on 2disks (sda and sdb)
datapool will be on 2 disks (sdc and sdd)
during PVE installation you may select ZFS
allocate 2 disks in mirror and limit volume space to 300G
after installation you may see status
zpool list -v
fdisk -l /dev/sda
fdisk -l /dev/sdb
...
PVE will be probably installed at sda1,sda2,sda3 and sdb1,sdb2,sdb3
respectively
and rpool will be probably ZFS mirror over the partitions sda3 and sdb3
after that you may create partitions sda4 and sdb4 (type Solaris /usr &
Apple ZFS)
with zpool mirror over it
zpool create -f -o ashift=12 ctpool mirror /dev/sda4 /dev/sdb4
after installation you may dedicate the rest 2 disks for datastore
e.g.
zpool create -f -o ashift=12 datapool mirror /dev/sdc /dev/sdd
finally you will declare your PVE storage and you may start to play ;-)
hope it helps

I'm planning to use SUPERMICRO 721 box (4 x 2T sata) as PBS
So, if I create zfs10 raid as boot drive , I have no more disks left
for datastore, right ?
BUT, is it possible to make directory on this / boot drive i.e.
/mnt/datastore and attach it as datastore ? Is that a way-to-go
and is there any disadvantages against separate 2 x 240g ssd as boot
and 4 x 2T sata (zfs raid 10 ) for datastore?
Actually I'ma having hard time finding 2 x 2,5" small sata drives for
boot ....
Thank you very much in advance
