Hi All,
I have four node ceph cluster. I have another three node setup for
openstack. I have integrated Ceph with openstack.
Whenever I try to create storage with ceph as storage backend for the
openstack vm, the creation process goes on forever in the horizon
dashboard.
It never completes. Also when attaching the ceph volume to the VM in
openstack, it freezes and goes on forever without completion.
To investigate this issue, I typed the ‘ceph –s’ command on the ceph
nodes. The health of ceph cluster is in warning state. It says it
detected clock skew
on two of the nodes. Is this time synchronization the reason beyond
the VM freezing while attaching volumes to VMs ?
Not sure, but you should make sure the time is synced. It CAN cause
issues inside the Ceph cluster.
Make sure it's HEALTH_OK before trying to do anything inside OpenStack.
Thanks
Kumar
