Comment 1 Eric Harney 2013-11-18 15:29:44 UTC

I logged into the Cinder node, it was set to lvm_type=default and had no thin pool in the VG.  I set the lvm_type to thin and restarted the volume service and seems to have created the pool successfully.

The log message from before indicates that it thought there was no pool, so tried to create one, but then LVM errored saying it already existed.

After that, cinder create seems to be working as expected.

Comment 2 Eric Harney 2013-11-18 15:51:57 UTC

The problem here was pool creation -- the secondary issue about failing to create a volume is bug 1022714.

Comment 6 Haim 2013-12-03 14:32:19 UTC

works for me on latest cinder versions:
