Have been testing Rancher Kubernetes with Ceph last few days and kept hitting this :

_MountVolume.SetUp failed for volume “log-pv” : rbd: failed to lock image log (maybe locked by other nodes), error fork/exec /usr/bin/rbd: invalid argument_

My pv and pvc:

NAME CAPACITY ACCESS MODES RECLAIM POLICY STATUS CLAIM STORAGECLASS REASON AGE  
pv/ceph-pv 1Gi RWX Retain Bound default/ceph-claim 11h  
pv/log-pv 1Gi RWX Retain Bound default/log-claim 3m

NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE  
pvc/ceph-claim Bound ceph-pv 1Gi RWX 11h  
pvc/log-claim Bound log-pv 1Gi RWX 2m

Ceph version -  
ceph version 11.2.0 (f223e27eeb35991352ebc1f67423d4ebc252adb7)

rancher@node-03:~$ sudo rbd info test/log  
rbd image ‘log’:

Anyone got this?
