the goal is to mount a LVM volume that is contained in a 8e partition of a zvol device.
Since we speak about a production system I stated from the basic and I wanted to see if pvs would recognize the partition. No luck.
root server02:/mnt# pvs -a /dev/zd1168p2
Failed to read physical volume "/dev/zd1168p2"
but on the other way on the same system I get
root server02:/mnt# pvs -a /dev/sdb2
PV VG Fmt Attr PSize PFree
/dev/sdb2 vgserver01 lvm2 a- 464.83g 432.82g
The only difference I can see between the 2 is the major number
root server02:/mnt# ls -la /dev/zd1168p2
brw-rw---- 1 root disk 230, 1170 Jun 10 19:56 /dev/zd1168p2
root server02:/mnt# ls -la /dev/sdb2
brw-rw---- 1 root disk 8, 18 Feb 11 10:43 /dev/sdb2
Is it an expected behaviour that I pvs doesn't recognize "physical device" within ZFS block devices?
