Hi, I only heard about GlusterFS last week, so am still a newbie. I have a question regarding using performance translators, in particular in a NUFA setup. A quick summary of my setup. I have two machines (a third is to be added): k9 has two bricks (16T and 2T), orac has one brick of 5T. I have used AFR for the namespace. My config is below. Everything seems to be working OK, but I would like to add in some performance translators and I'm not exactly sure where. There are five: read ahead, write behind, threaded IO, IO-cache, and booster. Which go where? On server or client? On each individual brick, or after the unify or afr? I have read the doco, that is why I've managed to get this far, I can see how I can stick in one or two translators, but not if I should have all of them and where they should all go. For instance I see IO-cache should go on the client side, but should it be on each brick, or on the unify or what? I know this is quite a big ask, but if someone could have a read through my config and perhaps show where I should stick in all the translators that would be great. Thank you muchly! Matt This is the config on k9 (the one on orac is very similar, I won't bother showing it here): volume brick0 type storage/posix option directory /export/brick0 end-volume volume brick1 type storage/posix option directory /export/brick1 end-volume volume brick-ns type storage/posix option directory /export/brick-ns end-volume volume server type protocol/server subvolumes brick0 brick1 brick-ns option transport-type tcp/server #option auth.ip.brick0.allow 127.0.0.1,130.123.129.121,130.123.128.35,130.123.128.28 # this is what i want, but it doesn't seem to work option auth.ip.brick0.allow * option auth.ip.brick1.allow * option auth.ip.brick-ns.allow * end-volume volume client-orac-0 type protocol/client option transport-type tcp/client option remote-host orac option remote-subvolume brick0 end-volume volume client-orac-ns type protocol/client option transport-type tcp/client option remote-host orac option remote-subvolume brick-ns end-volume volume afr-ns type cluster/afr subvolumes brick-ns client-orac-ns end-volume volume unify type cluster/unify option namespace afr-ns option scheduler nufa option nufa.local-volume-name brick0,brick1 option nufa.limits.min-free-disk 5% subvolumes brick0 brick1 client-orac-0 end-volume
