Hi,<br>
<br>
I have one question regarding the gluster failover...let me<br>
explain my current architecture,i am using Ovirt with gluster...<br>
<br>
1. One Ovirt Engine (Ovirt 3.4)<br>
2. 4 * Ovirt Node as well as Gluster storage node...with 12<br>
brick in one node...(Gluster Version 3.5)<br>
3. All 4 node in distributed replicated structure with replica<br>
level =2...<br>
4. I have one spare node with 12 brick for Failover purpose..<br>
<br>
Now there is two questions :-<br>
<br>
1. If any of brick failed...how i can failover this brick...how<br>
to remove the failed brick and replace with another brick....??<br>
Do i need to replace the whole node or i can replace the single<br>
brick ??<br>
<br>
</span></blockquote>
<br>
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.<span class=""><br>

2. If one of the whole node with 12 brick down and can not come<br>
up...how i can replace it with the new one....do i need to add<br>
two node to main the replication level... ??<br>
<br>

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.<span class="HOEnZb"><font color="#888888"><br>
