I've run into a similar problem when using VDO + LVM + XFS stacks, also with ZFS. If you're trying to use ZFS on 4.4, my recommendation is don't. You have to run the testing branch at minimum, and quiet a few things just don't work. As for VDO, i ran into this issue when using VDO and a NVME for LVM caching of the thin pool, VDO would throw a fit and under high load scenario, VM's would regularly pause. VDO with no cache was fine however, seems to be related to mixing device types / block sizes (even if you override block sizes). Not sure if that helps.

If you enabled sharding, don't disable it any more.My previous comment was just a statement and not a recommendation. Based on the output, the /home2/brick2  is part of the root. Obviosly, gluster thinks that the brick is full and you got very few options:- extend any brick or add more bricks to the volume- shutdown all VMs on that volume, reduce the minimum reserved space in gluster (gluster volume set data1 cluster.min-free-disk 0%) and then storage migrate the disk to a bigger datastore- shitdown all VMs on that volume(datastore),reduce the minimum reserved space in gluster (gluster volume set data1 cluster.min-free-disk 0%) and then delete unnecessary data (like snapshots you don't need any more). The first option is the most reliable. Once gluster has some free space to operate, you will be able to delete (consolidate) VM snapshots or to delete VMs that are less important (for example sandboxes, test VMs, etc). Yet, paused VMs will resume automatically and will continue to fill in Gluster which could lead to the same situation - so just power them off (ugly but most probably necessary).

Most peobably that VM has a very old snapshot. Sadly, 'deletion' ( merging snapahot to base disk) takes extra space. You have to find temporary storage that can be added to the volume , in order to delete that snapahot and free enough space.
