thank you for the reply.

ovirt2 same. ovirt3:
[root@ovirt3 prod ~]# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 279.4G 0 disk ├─sda1 8:1 0 500M 0 part /boot ├─sda2 8:2 0 4G 0 part [SWAP] └─sda3 8:3 0 274.9G 0 part ├─rootvg01-lv01 253:0 0 50G 0 lvm / └─rootvg01-lv02 253:1 0 224.9G 0 lvm /ovirt-store
See the difference between ovirt3 and other two nodes. LV 'rootvg01-lv02' in ovirt3 has only 224 GB of capacity. In replicated Gluster volume, storage capacity of the volume is limited by the smallest replica brick. If you want to have 1TB gluster volume then please make sure that all the bricks in the replicated volume has minimum 1TB capacity. Regards, Ramesh
Ah ha! I missed that. Thank you!! I can fix that.
Once I detached the storage domain it is no longer listed. Is there some option to make it show detached volumes?

I have a 3 node cluster with replica 3 gluster volume. But for some reason the volume is not using the full size available. I thought maybe it was because I had created a second gluster volume on same partition, so I tried to remove it.
I was able to put it in maintenance mode and detach it, but in no window was I able to get the "remove" option to be enabled. Now if I select "attach data" I see ovirt thinks the volume is still there, although it is not.
2 questions.
1. how do I clear out the old removed volume from ovirt?
To remove the storage domain, you need to detach the domain from the Data Center sub tab of Storage Domain. Once detached, the remove and format domain option should be available to you. Once you detach - what is the status of the storage domain? Does it show as Detached?
2. how do I get gluster to use the full disk space available?
Its a 1T partition but it only created a 225G gluster volume. Why? How do I get the space back?
What's the output of "lsblk"? Is it consistent across all 3 nodes?
All three nodes look the same: /dev/mapper/rootvg01-lv02 1.1T 135G 929G 13% /ovirt-store ovirt1-gl.j2noc.com:/gv1 225G 135G 91G 60% /rhev/data-center/mnt/glusterSD/ ovirt1-gl.j2noc.com :_gv1
