Hi all,
I'm affected by a stuck MDS warning for 2 clients: "failing to respond to cache
pressure". This is a false alarm as no MDS is under any cache pressure. The warning
is stuck already for a couple of days. I found some old threads about cases where the MDS
does not update flags/triggers for this warning in certain situations. Dating back to
luminous and I'm probably hitting one of these.
In these threads I could find a lot except for instructions for how to clear
this out in a nice way. Is there something I can do on the clients to clear
this warning? I don't want to evict/reboot just because of that.
echo 2 > /proc/sys/vm/drop_caches on the clients .... does that help?
