I'm playing around with glusterfs 3.0.0 on a server acting as both the glusterfs server and client. I've got a local directory (/mnt/gluster/gfs2) configured in /etc/glusterfs/glusterfsd.vol: volume posix1 type storage/posix option directory /mnt/gluster/gfs2 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 127.0.0.1 option transport.socket.listen-port 6996 option transport.socket.nodelay on subvolumes brick1 end-volume Glusterfsd starts without problems. The client config is as follows (gfs2-tcp.vol): volume localhost-1 type protocol/client option transport-type tcp option remote-host localhost 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 localhost-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 The /etc/booster.fstab: /etc/glusterfs/gfs2-tcp.vol /var/boot glusterfs subvolume=brick1,logfile=/var/log/glusterfs/gfs2.log,loglevel=DEBUG,attr_timeout=0 I start apache as follows: $ export GLUSTERFS_BOOSTER_FSTAB=/etc/booster.fstab $ LD_PRELOAD=/usr/lib/glusterfs/glusterfs-booster.so /usr/sbin/httpd I connect using cadaver and try to upload a file (install.log) and here's what I
