Hi,
We are running tversion 2.13.0.0 in our Production Lustre Environment and ran into the soft lock LDLM DOM issue.
We have however implemented the work around to clear the soft locks on the clients in order to keep the environment up and running.
Can you recommend any patches we can apply on version 2.13.0.0 and can they be applied while the system is running as i did read on a wiki that making changes to the file-system parameter will require the file-system to not be active?

Note
If the number of service threads is changed while the file system is running, the change may not take effect until the file system is stopped and rest.

Is version 2.12.8.0 also impacted by this bug and should we apply any patches?
