Hi Ceph-List,
i have set up a Ceph-Cluster with 3 OSDs, 3 Mons, 2 MDS over three server.
Server 1 has 2 ODSs (osd0,osd2) and one MON/MDS and Server 2 has only
osd2 and one MON + MDS.
Server 3 has only the third MON-Service.
All Servers are running Ceph 0.55 and Kernel 3.6.9 with Centos 6 64bit.
ceph osd shows me in first state
ceph osd tree
# id weight type name up/down reweight
-1 3 pool default
-3 3 rack unknownrack
-4 1 host unknownhost
1 1 osd.1 up 1
2 1 osd.2 up 1
0 1 osd.0 up 1
ceph health is ok !
now i have edit the crush map to the following
# id weight type name up/down reweight
-1 3 pool default
-3 3 rack unknownrack
-4 1 host testblade01
1 1 osd.1 up 1
-2 1 host unknownhost
2 1 osd.2 up 1
0 1 osd.0 up 1
now ceph is remaping some existing PGs and there are my problems began...
ceph is stopping remapping some PGs and the status is "current state
active+remapped" but nothing happens... after about 14h the PGs are in
the same state and ceph health is in status HEALTH_WARN. there are no
lost or unfound object, i can read all files in ceph without problems
and i can write into ceph storage.
how can i find the problem or force remapping of the PGs ? i have looked
into the source code, but i dont find a comman like "ceph pg force_remap
1.a4". "ceph pg PGNUMBER" shows me that there are no unfound objects.
any help ?
