Hi, I was hoping to use gluster to create a single unified storage volume then to be able to assign dynamic storage quotas to users for their home directory within this distributed storage area. I read about creating volume files and spotted the "quota" translator, which looks like it might help to do what I want. But I am using gluster 3.1 and tested out the CLI method to create my distributed replicated volume. I see where it has written the volume files under /etc/glusterd/vols but I suspect it would not be the right way to just start editing the -fuse.vol file there to add a quota volume? And anyway, I'm not sure about the right way to go about defining this...instinctively I would think to add quota volumes "above" the main distributed replicated volume for each user and then mount those quota volumes under /home with autofs (or something like that). Yet I also think that the chain of the volume/subvolume config should have perhaps only one volume that is not a subvolume of something else? In which case I can't have multiple quota volumes on top of the main distributed storage volume? I'm finding it all a bit difficult to understand in terms of where the config comes from to be honest. If I want to mount volume bar defined on server foo, it seems I can just use "foo:bar" as the device name in fstab and it manages to find that OK, but I don't entirely understand the mechanics of that. Is the fuse client talking to glusterd on server foo, or something else? Is it only going to look for a dir "bar" under /etc/glusterd/vols or is it searching all the .vol files for the defined volume names? And can I define a volume in one file that references a volume defined in another? Can I have multiple "top" volumes defined in one file? I have tried to read through the documentation, but my head is spinning a bit and I expect somebody on the list would be able to answer these questions very easily? Any info would be much appreciated, specifically in relation to what I want to do with storage quotas. Is it an appropriate use case for quota? Perhaps there is a better way to arrange this? Cheers! -Will
