As a test on 14.04 I created 2 test loop device files and used pvcreate on them (loop0 has zero metadata copies). ## In 14.04: $ sudo losetup -vf /var/lib/schroot/metadata-test.bin Loop device is /dev/loop0 $ sudo losetup -vf /var/lib/schroot/metadata-test-2.bin Loop device is /dev/loop1 $ sudo losetup -a /dev/loop0: [fc17]:2612 (/var/lib/schroot/metadata-test.bin) /dev/loop1: [fc17]:2613 (/var/lib/schroot/metadata-test-2.bin) $ file -s /dev/loop[0-1] /dev/loop0: LVM2 PV (Linux Logical Volume Manager), UUID: t304eP-t7dr-z52W-7Agt-nEdB-Kv7G-3dNObh, size: 1073741824 /dev/loop1: LVM2 PV (Linux Logical Volume Manager), UUID: 6194QF-wn0J-69C4-WCVc-rFxw-XwXJ-3fMXXb, size: 524288000 $ blkid /dev/loop[0-1] /dev/loop0: UUID="t304eP-t7dr-z52W-7Agt-nEdB-Kv7G-3dNObh" TYPE="LVM2_member" /dev/loop1: UUID="6194QF-wn0J-69C4-WCVc-rFxw-XwXJ-3fMXXb" TYPE="LVM2_member" $ sudo pvck /dev/loop[0-1] Found label on /dev/loop0, sector 0, type=LVM2 001 Found label on /dev/loop1, sector 1, type=LVM2 001 Found text metadata area: offset=4096, size=1044480 $ sudo pvs /dev/loop[0-1] PV VG Fmt Attr PSize PFree /dev/loop0 Test lvm2 a-- 1020.00m 1020.00m /dev/loop1 Test lvm2 a-- 496.00m 496.00m ## In 15.10 # file -s /dev/loop[0-1] /dev/loop0: LVM2 PV (Linux Logical Volume Manager), UUID: t304eP-t7dr-z52W-7Agt-nEdB-Kv7G-3dNObh, size: 1073741824 /dev/loop1: LVM2 PV (Linux Logical Volume Manager), UUID: 6194QF-wn0J-69C4-WCVc-rFxw-XwXJ-3fMXXb, size: 524288000 # blkid /dev/loop[0-1] /dev/loop0: UUID="t304eP-t7dr-z52W-7Agt-nEdB-Kv7G-3dNObh" TYPE="LVM2_member" /dev/loop1: UUID="6194QF-wn0J-69C4-WCVc-rFxw-XwXJ-3fMXXb" TYPE="LVM2_member" # pvck /dev/loop[0-1] Found label on /dev/loop0, sector 0, type=LVM2 001 Found label on /dev/loop1, sector 1, type=LVM2 001 Found text metadata area: offset=4096, size=1044480 # pvs /dev/loop[0-1] Failed to find physical volume "/dev/loop0".
