    Hi Alex,

    Im not sure if I understand right: You take a zfv-Volume to create a lvm
    volume inside? Make it sense to mix two similar concepts in this way? Imho
    zfs and lvm are focussed to different goals, so if you combine it, you get
    the worse of both.

    What is your goal mixing these concepts? If you have created a zfs-volume,
    you can mount it directly without detouring over lvm and vice versa.

    I think it is much better to decide for one of these (zfs-volumes XOR
    lvm-Volumes) depending on your needs.

    Just my 2ct

    Regards
    Oliver


Hi Oliver,

I see and back your point since the flexibility given by LVM can be obtained
with ZFS as well.
In this case I'm not trying to achieve anything but rather dealing with
something already existing and without making too many changes I'd like to
access that volume. I think my reasoning is correct but somehow I see
something non-expected. I thought I could use pvs, and lvs later on, on any
block device as for any physical disks.

Maybe pvs is coded to work only with some devices on purpose, I haven't looked
at the source. I don't think what I'm doing is wrong in theory and I would
like to know if instead, from the theoretically point of view, it is.

Thanks, Alex

Support for  ZFS partitions has been embedded into 2.02.106 lvm2 version.
You may as well add it to older version of lvm2 by updating your lvm.conf

https://bugzilla.redhat.com/show_bug.cgi?id=913597


You can add the following to your /etc/lvm.conf devices section to solve the issue:

types = [ "zvol", 16 ]
