Hi all, I have a problem here. I am using a gluster file system as a simple distributed storage (one storage server and multiple clients). I want to put php sessions inside this partition. In GlusterFS 2.0.9, it worked very well. PHP could write and read as quickly as possible. But in 3.0.0, PHP successfully writes files but can not read anything and freezes (juste after the writing). However, the gluster partition remains available et readable. Juste the quick write/read seems not to work. As anyone already encountered this problem ? Thanks for your help ! glusterfsd.vol : volume posix1 type storage/posix option directory /data end-volume volume locks1 type features/locks subvolumes posix1 end-volume volume brick1 type performance/io-threads option thread-count 8 subvolumes locks1 end-volume volume server-tcp type protocol/server option transport-type tcp option auth.addr.brick1.allow * option transport.socket.listen-port 6996 option transport.socket.nodelay on subvolumes brick1 end-volume glusterfs.vol : volume sys-zen-1 type protocol/client option transport-type tcp option remote-host sys-zen option transport.socket.nodelay on option transport.remote-port 6996 option remote-subvolume brick1 end-volume volume writebehind type performance/write-behind option cache-size 4MB subvolumes sys-zen-1 end-volume volume readahead type performance/read-ahead option page-count 4 subvolumes writebehind end-volume volume iocache type performance/io-cache option cache-size 1GB option cache-timeout 1 subvolumes readahead end-volume volume quickread type performance/quick-read option cache-timeout 1 option max-file-size 64kB subvolumes iocache end-volume volume statprefetch type performance/stat-prefetch subvolumes quickread end-volume Best regards.
