I'm having trouble getting stripe to perform as well as I'd expect. I've managed to get it to work pretty well with 2 machines in a stripe set with these files: server.vol: volume posix type storage/posix option directory /tmp/gluster end-volume volume locks type features/locks subvolumes posix end-volume volume io-threads type performance/io-threads option thread-count 16 subvolumes locks end-volume volume read-ahead type performance/read-ahead option page-count 16 subvolumes io-threads end-volume volume write-behind type performance/write-behind option cache-size 1MB subvolumes read-ahead end-volume volume server type protocol/server option transport-type tcp option auth.addr.write-behind.allow * subvolumes write-behind end-volume client.vol: volume machine01 type protocol/client option transport-type tcp option remote-host machine01 option remote-subvolume write-behind end-volume volume machine02 type protocol/client option transport-type tcp option remote-host machine02 option remote-subvolume write-behind end-volume volume stripe type cluster/stripe option block-size 1MB subvolumes machine01 machine02 end-volume volume read-ahead type performance/read-ahead option page-count 16 subvolumes stripe end-volume volume write-behind type performance/write-behind option cache-size 1MB subvolumes read-ahead end-volume I can saturate my link when catting a 4gb file to /dev/null at around 112MB/s. I'm having trouble, however, getting this to happen when I've got 4 machines in the stripe. I can only sustain about a 60-80MB/s read, though I manage to do a 112MB/s write. Anyone see anything obvious? Here's my client.vol file, and the server.vol is the same as above: volume machine01 type protocol/client option transport-type tcp option remote-host machine01 option remote-subvolume write-behind end-volume volume machine02 type protocol/client option transport-type tcp option remote-host machine02 option remote-subvolume write-behind end-volume volume machine03 type protocol/client option transport-type tcp option remote-host machine03 option remote-subvolume write-behind end-volume volume machine04 type protocol/client option transport-type tcp option remote-host machine04 option remote-subvolume write-behind end-volume volume stripe type cluster/stripe option block-size 1MB subvolumes machine01 machine02 machine03 machine04 end-volume volume read-ahead type performance/read-ahead option page-count 16 subvolumes stripe end-volume volume write-behind type performance/write-behind option cache-size 1MB subvolumes read-ahead end-volume
