I don't have any extra space to make another LV. I did have another thought that might be somehow causing the problem.
I recently reformatted and rebuilt our three RAID6 arrays into one huge VG. Before, we just had one LV for each RAID. I did this change and the update to 3.11 at the same time, so maybe the problem is the single VG across 3 RAIDs. Any chance that could be the problem? I hope not, because I've got about 4.5TB of data on it with no way of moving it off to another place to rebuild.![]()
