I have a 5x3 distributed-replicate gluster v3.3.1 volume on xfs bricks
running rhel6.3/x86_64. I've populated the volume with ~130G of data so
far and noticed that triplicate bricks consume different amounts of disk
space. Some triplicates have 2 of 3 bricks consume similar disk (1,2,3
triplicate below), 4th triplicate all different sizes, while the 5th
triplicate all consume the same amount of disk.
node2 19778644 1
node5 33154232 2
node8 18017708 3
node11 28565416 4
node14 34858100 5
Some more info... I started with just a replicated volume (1x3) then
added each triplicate followed by 'gluster volume rebalance gv0 start'
to end up with a 5x3 distributed-replicated volume. One more thing, I
have 'cluster.quorum-type: auto'. 'gluster volume heal gv0 full' runs
successfully and doesn't change disk usage.
Is brick disk consumption variance normal?
