Hmm. I just had to jump through lots of issues with a gluster 3.12.9 setup under Ovirt. The mounts are stock fuse.glusterfs. The RAM usage had been climbing and I had to move VMs around, put hosts in maintenance mode, do updates, restart. When the VMs were moved back the memory usage dropped back to normal. The new gluster is 3.12.11 and still using fuse in a replica 3 config. I'm blaming the fuse mount process for the leak (with no data to back it up yet). A different gluster install also using fuse mounts does not show the memory consumption. It does not use virtualization at all so it really is likely an issue with the kvm/qemu. On those system, the fuse mounts get dropped by oomkiller when computation use of memory overload things. Different issue totally.

I have 8 Gb machines occupying 40 Gb or ram, which theyweren't doing on the old cluster.It could be a proxmox problem, maybe a leak in their qemu, but sinceno one seems to be reporting that problem I wonder if maybe the newergluster might have a leak, I believe libgfapi isn't used much.I tried looking at the bug tracker but I don't see anything obvious, theonly leak I found seems to be for distributed volumes, but we only usereplica mode.Is anyone aware of a way to know if libgfapi is responsible or not ?Does it have any kind of reporting I could enable ? Worse case I couldalways boot a VM through the fuse mount instead of libgfapi, but that'snot ideal, it'd take a while to confirm._______________________________________________Gluster-users mailing listGluster-users@xxxxxxxxxxxhttps://lists.gluster.org/mailman/listinfo/gluster-users --James P.
