Hi,
I switch some disks from manual format to ceph-deploy (because slightly
different xfs-parameters) - all disks are on a single node of an 4-node
cluster.
After rebuilding the osd-disk one PG are incomplete:
ceph -s
cluster 591db070-15c1-4c7a-b107-67717bdb87d9
health HEALTH_WARN 1 pgs incomplete; 1 pgs stuck inactive; 1 pgs
stuck unclean
monmap e7: 3 mons at
{a=172.20.2.11:6789/0,b=172.20.2.64:6789/0,c=172.20.2.65:6789/0},
election epoch 1178, quorum 0,1,2 a,b,c
mdsmap e409: 1/1/1 up {0=b=up:active}, 2 up:standby
osdmap e22002: 52 osds: 52 up, 52 in
pgmap v10177038: 7408 pgs, 5 pools, 58618 GB data, 14662 kobjects
114 TB used, 76319 GB / 189 TB avail
7405 active+clean
1 incomplete
2 active+clean+scrubbing+deep
The pg are on one of the "rebuilded" disk (osd.42):
ceph pg map 6.289
osdmap e22002 pg 6.289 (6.289) -> up [42,31] acting [42,31]

How to say ceph, that the content on osd.31 is the right one?
I have tried an "ceph osd repair osd.42" without luck.
In the manual I saw only "ceph osd lost NN" but then all other data will
also rebuild to other disks I guess.
If "osd lost" the only option, how reuse osd-42? Waiting for an healthy
cluster and then recreate the disk?
Hope for an hint.
Best regards
Udo
