Hi,
I’ve tried to save some pg from a dead osd, I made this:
Picked on the same server an osd which is not really used and stopped that osd and import the exported one from the dead one.
root@server:~# ceph-objectstore-tool --data-path /var/lib/ceph/osd/ceph-33 --no-mon-config --pgid 44.c0s0 --op export --file ./pg44c0s0
Exporting 44.c0s0 info 44.c0s0( empty local-lis/les=0/0 n=0 ec=192123/175799 lis/c=4865474/4851556 les/c/f=4865475/4851557/0 sis=4865493)
Export successful
root@server:~# ceph-objectstore-tool --data-path /var/lib/ceph/osd/ceph-34 --no-mon-config --op import --file ./pg44c0s0
get_pg_num_history pg_num_history pg_num_history(e5583546 pg_nums {20={173213=256},21={219434=64},22={220991=64},24={219240=32},25={1446965=128},42={175793=32},43={197388=64},44={192123=512}} deleted_pools )
Importing pgid 44.c0s0
write_pg epoch 4865498 info 44.c0s0( empty local-lis/les=0/0 n=0 ec=192123/175799 lis/c=4865474/4851556 les/c/f=4865475/4851557/0 sis=4865493)
Import successful
Started back 34 and it says the osd is running but in the cluster map it is down :/
