One Ovirt Engine (Ovirt 3.4) 2. 4 * Ovirt Node as well as Gluster storage node...with 12 brick in one node...(Gluster Version 3.5) 3. All 4 node in distributed replicated structure with replica level =2... 4. I have one spare node with 12 brick for Failover purpose.. Now there is two questions :- 1. If any of brick failed...how i can failover this brick...how to remove the failed brick and replace with another brick....?? Do i need to replace the whole node or i can replace the single brick ??
Failure of a single brick can be addressed by performing "replace-brick commit force" to replace the failed brick with a new brick and then trigger self-heal to rebuild data on the replace brick.
2. If one of the whole node with 12 brick down and can not come up...how i can replace it with the new one....do i need to add two node to main the replication level... ??
You can add a replacement node to the cluster and use "replace-brick commit force" to adjust the volume topology. Self-healing will rebuild data on the new node. You might want to replace one/few bricks at a time to ensure that your servers do not get bogged down by self-healing.
