Hi,
Sorry to bother, but I have urgent situation: upgraded CEPH from 0.72 to
0.80 (centos 6.5), and now all my CloudStack HOSTS can not connect.
I did basic "yum update ceph" on the first MON leader, and all CEPH
services on that HOST, have been restarted - done same on other CEPH
nodes (I have 1MON + 2 OSD per physical host), then I have set variables
to optimal with "ceph osd crush tunables optimal" and after some
rebalancing, ceph shows HEALTH_OK.
Also, I can create new images with qemu-img -f rbd rbd:/cloudstack
Libvirt 1.2.3 was compiled while ceph was 0.72, but I got instructions
from Wido that I don't need to REcompile now with ceph 0.80...
Libvirt logs:
libvirt: Storage Driver error : Storage pool not found: no storage pool
with matching uuid Îhy<J~`a*×
Note there are some strange "uuid" - not sure what is happening ?
Did I forget to do something after CEPH upgrade ?
Have you got any ceph logs to examine on the host running libvirt? When
I try to connect a v0.72 client to v0.81 cluster I get:
2014-07-13 18:21:23.860898 7fc3bd2ca700 0 -- 192.168.122.41:0/1002012
