The following error occurred when I created the VM:
VDSM H5 command HSMGetAllTasksStatusesVDS failed: Error creating a new volume:
(u"Volume creation 62220be2-2781-4771-9373-84af5cc18f01 failed: (28, 'Sanlock
resource write failure', 'No space left on device')",)
This error is not about storage space, but sanlock lockspace, the area
where every
host updates its liveliness.
When activating a host, it takes 20-50 seconds until the hots joins the sanlock
lockspace. During this time there is no lockspace so sanlock operations may
fail with this error.
After an unclean shutdown (e.g power loss) sanlock needs to wait more time to
make sure no host is using the lockspace, so this state can last
several minutes.
oVirt engine monitors host lockspace status, and tries to avoid some operations
in this state. We also try to wait few minutes until a lockspace is
ready in other
cases, so this error should not happen.
If you are still experiencing this issue please file a bug and attach complete
engine and vdsm logs from the time this issue started.
