Hi all,
I'm upgrading ceph cluster from Hammer 0.94.9 to jewel 10.2.6.
The ceph cluster has 3 servers (one mon and one mds each) and another 6
servers with
12 osds each.
The monitoring and mds have been succesfully upgraded to latest jewel
release, however
after upgrade the first osd server(12 osds), ceph is not aware of them and
are marked as down
ceph -s
cluster 4a158d27-f750-41d5-9e7f-26ce4c9d2d45
health HEALTH_WARN
[...]
12/72 in osds are down
noout flag(s) set
osdmap e14010: 72 osds: 60 up, 72 in; 14641 remapped pgs
flags noout
[...]
ceph osd tree
3 3.64000 osd.3 down 1.00000 1.00000
8 3.64000 osd.8 down 1.00000 1.00000
14 3.64000 osd.14 down 1.00000 1.00000
18 3.64000 osd.18 down 1.00000 1.00000
21 3.64000 osd.21 down 1.00000 1.00000
28 3.64000 osd.28 down 1.00000 1.00000
31 3.64000 osd.31 down 1.00000 1.00000
37 3.64000 osd.37 down 1.00000 1.00000
42 3.64000 osd.42 down 1.00000 1.00000
47 3.64000 osd.47 down 1.00000 1.00000
51 3.64000 osd.51 down 1.00000 1.00000
56 3.64000 osd.56 down 1.00000 1.00000
If I run this command with one of the down osd
ceph osd in 14
osd.14 is already in.
however ceph doesn't mark it as up and the cluster health remains
in degraded state.
Do I have to upgrade all the osds to jewel first?
Any help as I'm running out of ideas?
Thanks
Jaime
