New subject: [ceph-users] Can't join new mon - lossy channel, failing

16 Aug 2023

Hi,

Let's do some serious necromancy here.

I just had this exact problem. Turns out that after rebooting all nodes 
(one at the time of course), the monitor could join perfectly.

Why? You tell me. We did not see any traces of the ip address in any 
dumps that we could get a hold of. I restarted all ceph-mgr beforehand 
as well.

Med vänliga hälsningar

  As last resort we've change ipaddr of this host,
and mon successfully joined to quorum. When revert ipaddr back - mon can't join, we
think there something on switch side or on old mon's side. From old mon's I was
checked new mon process connectivity via telnet - all works
 It's good to make a some reproducer of this network problem to know what exactly
message of ceph protocol is broken
