Hi List,
I remember that master node has the full copy for one DLM lock resource and the
other nodes have their own lock status,
then if one node is failed(or fenced), the DLM lock status can be recovered
from the remained node quickly.
My question is,
if there are more than one node which are failed at the same time, the DLM lock
service for the remained nodes in the cluster can still continue to work after
recovery?
Yes. The local DLM keeps a copy of its own locks and the remaining DLM
nodes will collaborate to re-master all of the locks that they know
about. The number of nodes that leave at one time has no impact on this.
