Try it with =E2=80=94force, if the disks have any kind of partition =
table on them, zfs will not allow you to over-write them by default.
If it=E2=80=99s still complaining about the disks being in use, it=E2=80=99=
s probably mutlipathd grabbing them. multipath -l or multipath -ll will =
show the to you. You may be able to get the pool creation done by doing =
=E2=80=98multipath -f=E2=80=99 to clear the ables and creating the pool =
before multipathd grabs the disks again, or you may want to read up on =
mutlipathd and edit your configs to prevent it from grabbing the disks =
you=E2=80=99re trying to use (or configure it for mutipath access to =
said disk, if you have the hardware for it).

Hello All,
I know this question is might be out of Ovirt scope, but I don't have =
anywhere else to ask for this issue (ZFS users mailing doesn't work), so =
I am trying my luck here anyway
so the issues go as follows :
=20
Installed ZFS on top of CentOs 7.4 with Ovirt 4.2 , on physical Dell =
R720 with 15
sas 10 k 1.2TB each attached to PERC H310 adapter, disks =
are configured to non-raid, all went OK, but when I am trying to create =
new zfs pool using the following command:
=20
zpool create -m none -o ashift=3D12 zvol raidz2 sda sdb sdc sdd sde =
sdf sdg sdh
sdi sdj sdk sdl sdm
I get the following error below:
/dev/sda is in use and contains a unknown filesystem.
/dev/sdb is in use and contains a unknown filesystem.
/dev/sdc is in use and contains a unknown filesystem.
/dev/sdd is in use and contains a unknown filesystem.
/dev/sde is in use and contains a unknown filesystem.
/dev/sdf is in use and contains a unknown filesystem.
/dev/sdg is in use and contains a unknown filesystem.
/dev/sdh is in use and contains a unknown filesystem.
/dev/sdi is in use and contains a unknown filesystem.
/dev/sdj is in use and contains a unknown filesystem.
/dev/sdk is in use and contains a unknown filesystem.
/dev/sdl is in use and contains a unknown filesystem.
/dev/sdm is in use and contains a unknown filesystem.

When typing command lsblk I get the following output below, all seems =
ok, any
idea what could be wrong?
Please advice
Thanks
