Hello eveybody.
I'm experimenting glusterfs which seems very promising.
BUT i'm facing some problems.
I'm trying to setup some X11/nomchaine/nx servers, all accesing a large
and global filesystem.
The system itself is on a local filesystem, but /home is a glusterfs.
Connection whith nx client hangs, and here are the errors on the client
2008-04-15 17:30:08 W [fuse-bridge.c:402:fuse_entry_cbk] glusterfs-fuse:
27570: (34) /comptes/dupont-y/.Xauthority => 8432041 Rehashing because
st_nlink less than dentry maps
2008-04-15 17:30:09 W [fuse-bridge.c:681:fuse_fd_cbk] glusterfs-fuse:
open() got EINTR
On server I got nothing special.
I'vre tried very recent version of glusterfs :
pulteney:~# glusterfs --version
glusterfs 1.3.8 built on Apr 11 2008 17:05:00
Repository revision: glusterfs--mainline--2.5--patch-739
and I simplified at maximum the config (without any performance enhancement)
