Hello Strahil, Thanks for your answer. I don't find the word "sharding" in the configfiles. There is not much shared data (24GB), and only 1 brick: --- root@xxx:/etc/glusterfs# gluster volume info DATA Volume Name: DATA Type: Distribute Volume ID: db53ece1-5def-4f7c-b59d-3a230824032a Status: Started Snapshot Count: 0 Number of Bricks: 1 Transport-type: tcp Bricks: Brick1: xxx-vpn:/DATA Options Reconfigured: transport.address-family: inet nfs.disable: on ---- (I have edited this a bit for privacy of my customer). I think they have used glusterfs because it can do ACLs.
