00:03 ada4u ok, problem is i have two nics per machine , and two nets, replication is ok betwen one subnet, but is not visible from the other nic, is situable export with nfs to the other nic-network?
00:03 ada4u tks
00:14 ada4u ok i've reading thread, guess is the problem with one network for replication and second for clients, replication network is 10.0.0.1 and 10.0.0.2, and client - gluster server is 192.168.1.1 and 192.168.1.2, replication betwen 10.0.0.1 and 10.0.0.2 is ok, but I can't mount 192.168.1.2 to 192.168.1.1 neither with nfs mount, :(

18:18 samppah hmmh.. I'm happy with qemu gluster (libgfapi) performance but I think that it's somewhat limiting at least random io performance with qcow2 images..
18:18 bennyturns joined #gluster
18:18 samppah is there some either intentional or unintentional known limitations on that?
18:35 JoeJulian samppah: The only real limitation that I can think of is that "copy on write" requires a that the sector be read, updated and written again. Perhaps that adds more overhead than a raw image would.
18:36 samppah JoeJulian: that's a good point
18:39 samppah http://supercolony.gluster.org/pipermail/gluster-users/2013-November/037858.html this thread is offtopic but he mentions that "qcow2 operates on 64 KB clusters by default so 4 KB disks

18:39 samppah work."
18:40 samppah just wondering if there is some extra tuning required network wise for best performance
18:40 JoeJulian So unless you have 64k super-jumbo frames.... ;)

18:42 samppah JoeJulian: lol :D
18:44 samppah JoeJulian: well, that's a good reminder.. i guess i haven't even configured jumbo frames yet :S
