Hello Strahil, I just set cluster.min-free-disk to 1%: # gluster volume info data
Volume Name: data Type: Distribute Volume ID: 2d3ea533-aca3-41c4-8cb6-239fe4f82bc3 Status: Started Snapshot Count: 0 Number of Bricks: 1 Transport-type: tcp Bricks: Brick1: node2.domain.com:/home/brick1 Options Reconfigured: cluster.min-free-disk: 1% cluster.data-self-heal-algorithm: full performance.low-prio-threads: 32 features.shard-block-size: 512MB features.shard: on storage.owner-gid: 36 storage.owner-uid: 36 transport.address-family: inet nfs.disable: on But still get the same error: Error while executing action: Cannot move Virtual Disk. Low disk space on Storage Domain I restarted the glusterfs volume. But I can not do anything with the VM disk. I know that filling the bricks is very bad, we lost access to the VM. I think there should be a mechanism to prevent stopping the VM. we should continue to have access to the VM to free some space. If you have a VM with a Thin Provision disk, if the VM fills the entire disk, we got the same problem. Any idea?

You can power off the VM , then set cluster.min-free-disk to 1% and immediately move any of the VM's disks to another storage domain. Keep in mind that filling your bricks is bad and if you eat that reserve , the only option would be to try to export the VM as OVA and then wipe from current storage and import in a bigger storage domain. Of course it would be more sensible to just expand the gluster volume (either scale-up the bricks -> add more disks, or scale-out -> adding more servers with disks on them), but I guess that is not an option - right ?

I have a small GlusterFS Domain storage brick on a dedicated filesystem serving only one VM. The VM filled all the Domain storage. The Linux filesystem has 4.1G available and 100% used, the mounted brick has 0GB available and 100% used I can not do anything with this disk, for example, if I try to move it to another Gluster Domain Storage get the message: Error while executing action: Cannot move Virtual Disk.
