Hi Team,
We have ceph setup with 2 OSD and replica 2 and it is mounted with ocfs2 clients and its working. When we added new osd all the clients rbd mapped device disconnected and got hanged by running rbd ls or rbd map command. We waited for long hours to scale the new osd size but peering not completed event data sync finished, but client side issue was persist and thought to try old osd service stop/start, after some time rbd mapped automatically using existing map script.
After service stop/start in old osd again 3rd OSD rebuild and back filling started and after some time clients rbd mapped device disconnected and got hanged by running rbd ls or rbd map command. We thought to wait till to finished data sync in 3'rd OSD and its completed, even though client side rbd not mapped. After we restarted all mon and osd service and client side issue got fixed and mounted rbd. We suspected some issue in our setup. also attached logs for your reference.
Something we are missing in our setup i don't know, highly appreciated if anybody help us to solve this issue.
Before new osd.2 addition :
osd.0 - size : 13T and used 2.7 T
osd.1 - size : 13T and used 2.7 T
After new osd addition :
osd.0 size : 13T and used 1.8T
osd.1 size : 13T and used 2.1T
osd.2 size : 15T and used 2.5T
rbd ls
repo / integrepository (pg_num: 126)
rbd / integdownloads (pg_num: 64)
Also we would like to know few clarifications .
If any new osd will be added whether all client will be unmounted automatically .
While add new osd can we access ( read / write ) from client machines ?
How much data will be added in new osd - without change any repilca / pg_num ?
How long to take finish this process ?
If we missed any common configuration - please share the same .
