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

Ceph version -
