Hi,
I'm hoping this is a known issue. I'm trying to use thin provisioning with
openstack cinder.
If I run "vgchange -ay cinder-volumes" manually, it complains:
controller-0:/home/wrsroot# vgchange -ay cinder-volumes
Check of thin pool cinder-volumes/cinder-volumes-pool failed (status:1).
Manual repair required (thin_dump --repair
/dev/mapper/cinder-volumes-cinder-volumes-pool_tmeta)!
If I run thin_check on /dev/mapper/cinder-volumes-cinder-volumes-pool_tmeta it
complains that the file doesn't exist:
controller-0:/home/wrsroot# thin_check
/dev/mapper/cinder-volumes-cinder-volumes-pool_tmeta
Couldn't stat dev path
The actual file name is /dev/mapper/cinder--volumes-cinder--volumes--pool_tmeta
(note the double-hyphens) and if I run thin_check on that then it seems happy:
controller-0:/home/wrsroot# thin_check
/dev/mapper/cinder--volumes-cinder--volumes--pool_tmeta
examining superblock
examining devices tree
examining mapping tree
checking space map counts
Does anyone know why thin_check is being called with the wrong filename?
For what it's worth, here's my lvm version:
controller-0:/home/wrsroot# lvm version
LVM version: 2.02.95(2) (2012-03-06)
Library version: 1.02.74 (2012-03-06)
Driver version: 4.24.0
Thanks,
Chris
