Issues with ZFS volume creation
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 : 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:
zpool create -m none -o ashift=12 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 # lsblk

Hello Tal,
ZFS is probably detecting a partition table on the disks, you could delete the partition tables on /dev/sda,/dev/sdb ... etc, or you could use the force option of ZFS create making sure they aren't mounted somewhere.

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 :
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:
zpool create -m none -o ashift=12 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

Or try to create the vdev on the multipath devices, what does lsblk -s says ? It will show you the top level device to be used.
