New user of urbackup. Installed on server Ubuntu 18.04, then added the linux client to the same machine and 3 linux (ubuntu 18 and 19) PCs. For all of them, when I installed the linux client, it prompts me for which snapshot system to use. I didn’t see any recommendations for what to pick so I chose LVM for all of them, after it verified that it had detected that I’m using LVM.
I created a new btrfs volume to back up to.
For every client backup, I get the same error:
Creating snapshot of “/” failed
Cannot create snapshot of file system with type ext4
Creating snapshot of “root” failed.
After reading forums etc my best guess is that I don’t have room on my LVM volume.
So on the server, I followed this guide on techmint and expanded the volume from 100GB to 200GB. I still got the same exact error, so I’ve now expanded it again to 300GB, but still get the same error. Here’s my current ‘df -h’ output:

Because every client backup has the same errors, I’m assuming that it’s nothing to do with the machine and something to do with how I’m setting things up.
If the errors I’m getting are because I don’t have enough space, why isn’t expanding it helping? Is there any way to tell whether I’m running out of space during the backup, so that I know how much more I need to expand it? Or am I wasting my time trying that?
