Hello,
I have a cluster of 3 debian ceph machines running version:
ceph version 0.80.1 (a38fe1169b6d2ac98b427334c12d7cf81f809b74)
A new disk was added to one node but it does not want to start it. I
have tried everything like removing and readding the disk any times.
The current ceph osd tree:
# id weight type name up/down reweight
-1 29 root default
-2 9.06 host store1
0 1.81 osd.0 up 1
5 1.81 osd.5 up 1
6 1.81 osd.6 up 1
9 3.63 osd.9 up 1
-3 9.06 host store3
1 1.81 osd.1 up 1
2 1.81 osd.2 up 1
8 1.81 osd.8 up 1
11 3.63 osd.11 up 1
-4 10.88 host store2
3 1.81 osd.3 up 1
7 1.81 osd.7 up 1
10 3.63 osd.10 up 1
4 3.63 osd.4 down 0 < problem is with this disk
All the disks are 4TB.
/etc/init.d/ceph start osd.4
=== osd.4 ===
create-or-move updated item name 'osd.4' weight 3.63 at location
{host=store2,root=default} to crush map
Starting Ceph osd.4 on store2...
starting osd.4 at :/0 osd_data /var/lib/ceph/osd/ceph-4
/var/lib/ceph/osd/ceph-4/journal
If I look into the disk, it did create the basic ceph directory but it
does not use it:
/dev/sdc1 3.7T 5.1G 3.7T 1% /var/lib/ceph/osd/ceph-4
The ceph health status:
cluster <ID>
health HEALTH_WARN 4 pgs degraded; 113 pgs stuck unclean; recovery
45/5084377 objects degraded (0.001%); 1 near full osd(s)

Any idea how to fix this? If it possible without upgrade. I don't want
to upgrade this cluster to other version ever. It does it's job as it
should.
Thank you,
Claude
