Re: Can't join new mon - lossy channel, failing

I guess:

strace ceph-mon -d --id mon2 --setuser ceph --setgroup ceph

should do.


Try -f instead of -d if you are overwhelmed with output to get mon debug output to log file.

May be it is good idea to run mon under strace and see why your network does not permit the frame read? msgr2 will show the message you have referred to in case if no data is actually received from the network.

Do you know how exactly start strace do determine this?
