unable to commit changes

I"m not sure if this is a zneoss problem, a docker problem or a control center problem. for the past week i've been getting traceback errors when modeling windows servers of OS versions. i thought perhaps this would resolve itself if i update the windows zenpack to current version isntead of the preinstalled version that core5 comes with.

following the core5 administration guide i'm having trouble making changes. specifically i access the shell, run a command, then exit and attempt to commit and get the following....

unable to run cmd:[btrfs subvolume snapshot -r /opt/serviced/var/volumes/1yjozxwei100w07h6btyful3n /opt/serviced/var/volumes/1yjozxwei100w07h6btyful3n_20150623-144438] output:ERROR: '/opt/serviced/var/volumes/1yjozxwei100w07h6btyful3n' is not a subvolume
error:exit status 1
[root@zenoss ~]#

I've done some searching on google and this forum but have not been able to figure out why i get this. any help would be greatly appreciated. my understanding however is that this means any change i've made will not be live until i am able to successfully comit

Version info: Zenoss Core5 on Centos 7 via ESXi vmware 5.5 Current zenpack version is 2.3.1, attempting upgrade to 2.4.4

Side note: got the same subvolumes message when attempting to install esx zenpack.
