You have replica2 so you can't really take 50% of your cluster down without turning off quorum (and risking split brain). So detaching the rebuilding peer is really not an option. If you had replica3 or an arbiter, you CAN detach or isolate the problem peer.  I've done things like change the

I only got this issue with this one template (CentOS7), i checked other templates and it worked fine. I didn't quite understand what you need, i have one UUID and three files, one for the img and .meta and the other one is .lease. I got the output of all three files which represent the VM i

That make sense ^_^ Unfortunately I haven't kept the interresting data you need. Basically I had some write errors on my gluster clients when my monitoring tool tested mkdir & create files. The server's load was huge during the healing (cpu at 100%), and the disk latency increased a lot.

OK. Is this problem unique to templates for a particular guest OS type? Or is this something you see for all guest OS? Also, can you get the output of `getfattr -d -m . -e hex ` for the following two "paths" from all of the bricks: path to the file representing the vm created off this template

Hi, There is no way to isolate the healing peer. Healing happens from the good brick to the bad brick. I guess your replica bricks are on a different peers. If you try to isolate the healing peer, it will stop the healing process itself. What is the error you are getting while writing? It would

Hi everyone, I've been using gluster for a few month now, on a simple 2 peers replicated infrastructure, 22Tb each. One of the peers has been offline last week during 10 hours (raid resync after a disk crash), and while my gluster server was healing bricks, I could see some write errors on
