Hello
Note that Gluster hasn't all the VSAN features yet so you will be able to
replicate data.
Also I personally think replica=3 is overkill and waste of space for mos
scenarios. 2 should be enough and give a raid 1 like.
I'm not sure it's like RAID 1. In RAID 1, when one disk fails, I'm pretty
sure I know where the correct data is.
In Gluster, if you have a split brain, where's the correct data?
I suggest perhaps using an arbiter.
