Hi, I'm trying to use glusterfs to mirror the ownCloud "data" area between 2 servers. They are using debian jessie due to some dependancies that I have for other components. This is where my issue rears it's ugly head. This is failing because I can't stat the files and directories on my glusterfs mount. /var/www/owncloud/data is where I am mounting the volume and I can reproduce the error using a simple php test application, so I don't think that it is apache or owncloud related. I'd be grateful for any pointers on how to resolve this problem. Thanks, Bill Attached is "simple.php" test and the results of executing "strace php5 simple.php" twice, once with the glusterfs mounted (simple.php.strace-glusterfs) and once against the file system when unmounted (simple.php.strace-unmounted). Here is what I get in the gluster log when I run the test (as root): /var/log/glusterfs/var-www-owncloud-data.log [2013-12-05 18:33:50.802250] D [client-handshake.c:185:client_start_ping]
