Hi all,
I have on my 2 Centos5 machines fuse2.7.2gls8 and glusterfs tla .
Everything works fine, as long as I don't sync the machines.
One of the things I see al the time is that most files are not
synced on
both servers. When I try to force a sync using find /mail -type f
-exec
head -c 1 {} \; >/dev/null
I get the following crash after a few minutes:
2008-01-31 10:08:00 E [server-protocol.c:178:generic_reply] server:
transport_writev failed
2008-01-31 10:08:00 D [inode.c:308:__destroy_inode] mail/inode:

The pot's at the other end.
