[lustre-discuss] ldlm_expired_completion_wait - lock timed out

Hi all,

is there a way to find out who/which client is behind frequent 'lock timed out' on the MDS?

These keep bringing down our Lustre (2.12.5)

And in contrast to e.g. 'lock callback timer expired', the NID mentioned is always 'local'.
Does this mean the error is actually on the MDS?
