<br>
I had a replica 2 cluster to host my VM images from my Proxmox cluster.<br>
I got a bit around split brain scenarios by using "nufa" to make sure<br>
the files are located on the host where the machine also runs normally.<br>
So in fact one replica could fail and I still had the VM working.<br>
<br>
But then I thought about doing better and decided to add a node to<br>
increase replica and I decided against arbiter approach. During this I<br>
also decided to go away from nufa to make it a more normal approach.<br>
<br>
But in fact by adding the third replica and removing nufa I'm not really<br>
better on availability - only split-brain-chance. I'm still at the point<br>
that only one node is allowed to fail because else the now active client<br>
quorum is no longer met and FS goes read only (which in fact is not<br>
really better then failing completely as it was before).<br>
<br>
So I thought about adding arbiter bricks as "kind of 4th replica (but<br>
without space needs) ... but then I read in docs that only "replica 3<br>
arbiter 1" is allowed as combination. Is this still true?<br>
If docs are true: Why arbiter is not allowed for higher replica counts?<br>
It would allow to improve on client quorum in my understanding.<br>
<br>
Thank you for your opinion and/or facts :-)<br>
<br>
Ingo<br>
