Re: [ceph-users] Cannot add OSD node into crushmap or all writes fail

[Henrik Korkuc]

check firewall rules, network connectivity.
Can all nodes and clients reach each other? Can you telnet to OSD ports 
(note that multiple OSDs may listen on differenct ports)?

I've been trying to figure this out for weeks! None of the logs 
contain anything relevant at all.


If I disable the node in the crushmap the rbd clients immediately 
begin writing to the other nodes.


Ideas?

[ceph-users] Cannot add OSD node into crushmap or all writes fail

I have this ceph node that will correctly recover into my ceph pool and 
performance looks to be normal for the rbd clients. However after a few minutes 
once finishing recovery the rbd clients begin to fall over and cannot write 
data to the pool.
