Description
Hi，everyone;
I use luminous v12.2.5，and i try to recovery monitor database from osds,
I perform step by step according to the official website's documentation
http://docs.ceph.com/docs/master/rados/troubleshooting/troubleshooting-mon/#recovery-using-osds,
i have 2 hosts A and B, 3 osds per host.
but after i collected map from osds of A and rsync mon store to B, and try to collect map from B,
it print a errer "unable to open mon store /tmp/mon-store"，here were what i did.
step1: collect from host A
[root@gz-open-dw-c204 recover]# MS=/tmp/mon-store/; mkdir $MS; host=gz-open-dw-c204; ssh -t root@$host "for osd in /var/lib/ceph/osd/ceph-*; do ceph-objectstore-tool --type bluestore --data-path \$osd --op update-mon-db --mon-store-path $MS; done"
root@gz-open-dw-c204's password:
osd.0 : 0 osdmaps trimmed, 52 osdmaps added.
267 pgs added.
osd.1 : 0 osdmaps trimmed, 0 osdmaps added.
259 pgs added.
osd.2 : 0 osdmaps trimmed, 0 osdmaps added.
242 pgs added.
Connection to gz-open-dw-c204 closed.
step2: rsync to host B
[root@gz-open-dw-c204 recover]# MS=/tmp/mon-store; host=gz-open-dw-c205; rsync -avz $MS/ root@$host:$MS/ root@gz-open-dw-c205's password: sending incremental file list created directory /tmp/mon-store ./ kv_backend store.db.wal/ store.db.wal/000009.log store.db/ store.db/CURRENT store.db/IDENTITY store.db/LOCK store.db/MANIFEST-000008 store.db/OPTIONS-000008 store.db/OPTIONS-000011 sent 16457 bytes received 175 bytes 3696.00 bytes/sec total size is 148691 speedup is 8.94
step3: collect from B
[root@gz-open-dw-c204 recover]# MS=/tmp/mon-store/; host=gz-open-dw-c205; ssh -t root@$host "for osd in /var/lib/ceph/osd/ceph-*; do ceph-objectstore-tool --type bluestore --data-path \$osd --op update-mon-db --mon-store-path $MS; done" root@gz-open-dw-c205's password: unable to open mon store: /tmp/mon-store/ unable to open mon store: /tmp/mon-store/ unable to open mon store: /tmp/mon-store/ Connection to gz-open-dw-c205 closed.
