Hi all, experimenting with posix-locks, I found that my daemon segfaults with posix-locks loaded. Here's my simple configuration: server: volume data-posix type storage/posix option directory /mnt/export end-volume volume data type features/posix-locks subvolumes data-posix end-volume volume data-server type protocol/server option transport-type tcp/server subvolumes data option auth.ip.data.allow a.b.c.23,a.b.c.11 end-volume client: volume data type protocol/client option transport-type tcp/client option remote-host myserver option remote-subvolume data end-volume Without the posix-locks xlator on the server side, everything works as it should. The segfault occurs when I copy a file into the directory on that GlusterFS is mounted. ls works fine. You can find the backtrace at http://glusterfs.pastebin.com/m7289f4c4 Thanks for your help, -- cc
