Hi Marcel,
If this issue related to only one monitor?
If yes, check the overall node status: average load, disk I/O, RAM
consumption, swap size, etc. Could be not a ceph-related issue.
Regards,
Vladimir.

Hi
One of my clusters running nautilus 14.2.8 is very slow (13 seconds or so
where my other clusters are returning almost instantanious) when doing a
'rados --pool rc3-se.rgw.buckets.index ls' from one of the monitors.
I checked
- ceph status => OK
- routing to/from osds ok (I see a lot of established connections to osds
due to the command, nothing in syn_sent indicating incomplete handshake)
- ping times are OK
- no interface errors
- no packet drops
- no increasing send queus
- and as far as I can see nothing out of the ordinary in mon and osd logs
I have no clue how to debug the issue. If someone has pointers it would be
much appreciated
Kind Regards
Marcel
