That's a good question and I don't have an answer for you, unfortunately. I just tried to reproduce it by disabling ms_bind_msgr2 for one OSD, but didn't find such log entries. Hopefully someone else has some more insights. Zitat von Frank Schilder <frans@dtu.dk>:

Hi Eugen,

I have found these threads and am not entirely convinced that they apply to our situation. Most importantly, the IP addresses cannot be clients, because they are in the replication network, which clients don't have access to. The formulation of the message sounds a lot like a PG peer is using v1 instead of v2. Both peers in the log message have v1 and v2 addresses though.

The log messages with v1 clients looked different. Apart from that, if this is normal, why the continuous log entries - why not just one on connect? I can't get the old kernel clients to talk v2, so its basically log spam. Let's say its the clients, I didn't see a resolution. How can I shut off these messages?

Thanks a lot! ================= Frank Schilder AIT Risø Campus Bygning 109, rum S14

Hi,

this sounds familiar, I believe this means that (some) of your clients are using msgr_v1. I assume that your MONs are configured to use both v1 and v2? I read somewhere that kernel clients might not support v2, but I'm not really sure. But there are a couple of threads discussing this.

Hi all,

on an octopus latest cluster I see a lot of these log messages:

Jan 13 20:00:25 ceph-21 journal: 2023-01-13T20:00:25.366+0100 7f47702b8700 -1 --2- [v2:192.168.16.96:6826/5724,v1:192.168.16.96:6827/5724] >> [v2:192.168.16.93:6928/3503064,v1:192.168.16.93:6929/3503064] conn(0x55c867624400 0x55c7e9dfa800 unknown :-1 s=BANNER_CONNECTING pgs=22826 cs=73364 l=0 rev1=1 rx=0 tx=0)._handle_peer_banner peer [v2:192.168.16.93:6928/3503064,v1:192.168.16.93:6929/3503064] is using msgr V1 protocol

These addresses are on the replication network and both hosts are OSD hosts.

What is the reason for these messages and how can I fix it?

Thanks a lot! ================= Frank Schilder AIT Risø Campus Bygning 109, rum S14 _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-leave@ceph.io
