Hi,
my "/dev/sdc" is LVM PV and "bkid says so - sometimes:
---8<---
root@ai:~# blkid /dev/sdc
root@ai:~# blkid /dev/sdc
/dev/sdc: UUID=",,," TYPE="LVM2_member"
root@ai:~# blkid /dev/sdc
/dev/sdc: UUID="..." TYPE="LVM2_member"
root@ai:~# blkid /dev/sdc
root@ai:~# blkid /dev/sdc
/dev/sdc: UUID="..." TYPE="LVM2_member"
,,,
--->8---
When looking at "blkid.tab" after each blkid invocation, it seems a
record for "/dev/sdc" is added and then is removed again.
"blkid" from 2.21 did not have that problem, and a git bisect revealed
commit 2b29c1bfca6e52c9c1ce2e41fde7967c150c5877 as the culprit.
Reverting that commit made "blkid.tab" and "blkid" output stable.
Ciao
Andi
