Hello,
I have a cluster of 3 nodes, 3 OSD per nodes (so 9 OSD in total), replication set to 3 (os each node has a copy).
For some reason, I would like to recreate the node 1. What I have done :
1. out the 3 OSDs of node 1, stop then, then destroy them (almost in the same time)
2. recreate the new node 1 and add the 3 new OSDs
My problem is that after step 1, I had to wait for backfilling to complete (to get only active+clean+remapped and active+undersized+degraded PGs). Then, wait again in step 2 to get the cluster healthy.
Could I avoid the wait of step 1 ? What should I do then ? I was thinking :
- set the OSDs to noout
- out/stop/destroy the 3 OSDs of node 1 (in the same time)
- reinstall node 1 (I have a copy of all the configuration files) and add the 3 nodes
Would that work ?
Thanks and regards,
Mosi
