Hi, We found something strange with new glusterfs-2.0.0rc1. Previously, we worked on 1.3.12, and some time ago upgraded to 2.0.0. So our configuration is 2 web servers web1 and web2. On gluster we store only webscripts, for High Availability, in case one server down. Glusterfs configured in simple single process AFR. All changes we made on first server (web1). After some time we found that some script files on _second_ server have content of other files. Making diff of all files md5sum show some files have different checksum on different servers. But this checksums have other files on glusterfs tree. For examples file Web1: /gluster/joinus.php 954fdb7686c1a8836b863fa8a09deeb8 Web1: /gluster/lib.php 9cd1fb4db6021d37f3098d361b089f65 Web2: /gluster/joinus.php 9cd1fb4db6021d37f3098d361b089f65 Web2: /gluster/lib.php 9cd1fb4db6021d37f3098d361b089f65 If we open joinus.php and lib.php they are the same on web2, but on web1 this file is different. The way that this conflict can be solved is: web1# mv joinus.php joinus.php1 web2# mv joinus.php1 joinus.php after this we have: Web1: /gluster/joinus.php 954fdb7686c1a8836b863fa8a09deeb8 Web2: /gluster/joinus.php 954fdb7686c1a8836b863fa8a09deeb8 In logs i found nothing.
