Yes, I can take the downtime. Actually, I don't have any choice at the moment because it is a single node setup. :) I think this is a distributed volume from the research I have performed. I posted the lvchange command in my last post, this was the result- I ran the command lvchange -an /dev/gluster_vg1/lv_datadisks When I do this I get the message "Volume group "gluster_vg1" not found. Cannot process volume group gluster_vg1". I also tried the command the way you specified with just the LV and get the same results. I had placed the system in Global maintenance mode prior to the reboot. Upon reboot I got the messages about the various gluster volumes not being able to be mounted because of timeout issues. That is what started my OP. I think we are both thinking along the same lines regarding the issue. I think the question is how do you fix a volume that the system won't mount? It does seem likely that the thinpool needs to be repaired but what do you do if you can't even perform the first step in the procedure?
