Hi David, any storage operation can cause unexpected situations, so always plan your activites for low traffic hours and test them on your test environment in advance. I think it's easier if you (command line): -verify no heals are pending. Not a single one.- set the host to maintenance over ovirt- remove the third node from gluster volumes (remove-brick replica 2)- umount the bricks on the third node- recreate a smaller LV with '-i maxpct=90 size=512' and mount it with the same options like the rest of the nodes. Usually I use 'noatime,inode64,context=system_u:object_r:glusterd_brick_t:s0'- add this new brick (add-brick replica 3 arbiter 1) to the volume- wait for the heals to finish Then repeat again for each volume. Adding the new disks should be done later.

I'm running critically low on disk space, and need to add space. To that end, I've ordered 8x 800GB ssd drives, and plan to put 4 drives in 1 server, and 4 drives in the other. What's my best option for reconfiguring the hyperconverged cluster, to change gluster storage away from Replica 3 to a Replica 2 / Arbiter model? I'd really prefer not to have to reinstall things from scratch, but I'll do that if I have to. My most important requirement is that I cannot have any downtime for my VMs (so I can only reconfigure 1 host at a time).
