add fourth full gluster node and remove arbiter: ovirt 4.1 with hosted engine
Hi at all, we have a 3 node cluster with this configuration: ovirtzz 4.1 with 3 node hyperconverged with gluster. 2 node are "full replicated" and 1 node is the arbiter. Now we have a new server to add to cluster then we want to add this new server and remove the arbiter (or, make this new server a "full replicated" gluster with arbiter role? I don't know) Can you please help me to know what is the right way to do this? Or, Can you give me any doc or link that explain the steps to do this? Thank you in advance!

Since you have a new you can add this as fourth node and create another gluster volume (replica 3) out of this node plus the other two nodes and run vm images there as well.

Hi, And thanks for the answer. The actual arbiter must be removed because is too obsolete. So, I needs to add the new "full replicated" node but I want to know what are the steps for add a new "full replicated" node and remove the arbiter node (Also a way to move the arbiter role to the new node, If needed) . Extra info: I want to know if I can do this on an existing ovirt gluster Data Domain (called Data01) because we have many vm runnig on it. thank you

Hi, I have found this doc from RH about replacing host in a gluster env: https://access.redhat.com/documentation/en-US/Red_Hat_Storage/3/html/Adminis... I can use the command described at point 7 ? # *gluster volume replace-brick vol sys0.example.com:/rhs/brick1/b1 sys5.example.com:/rhs/brick1/b1 commit force* *volume replace-brick: success: replace-brick commit successful* The question is: The replaced node will be a data node (a "full replicated" node) or will be again an arbiter? Thank you

Hi, And sorry for delay 2017-06-30 14:09 GMT+02:00 knarra <knarra@redhat.com>:
We have a new server with the same hard disk size of other two node, so, why not? Why join the cluster as an arbiter when we can have the same disk capacity to add extra replication?
I need this (reads: I need the arbiter role) if I reduce replica count then I add the new node as full replica and increasing replica count again to 3? (As you expained above) Thank you
