Hello,

since a few weeks a get the following log entry once or twice a week:

kernel: libceph: osd9 10.10.23.12:6824 socket error on write

Of the 40 OSD#s its only osd9 which is having problems. I cannot find any other relevant ceph logs. The ceph dashboard says everything is ok.

I'm running Virtual Environment 5.4-13 with Kernel 4.15.18-21-pve

Thanks a lot!
 
Hi,

are there actual negative symptoms in the cluster or is it "just" this error message?

If ceph health does not show any issues you should be good. That messages are from when the OSD <-> monitor connection fails to work (network load, ..?) temporarily. This can happen during backups, other high traffic situations, restarts of monitors, ..
Normally nothing to worry, as long as it is only temporarily.
