Jordi, We will be trying to reproduce your problem at our setup. To go further, we have few questions for you: 1. Where are glusterfs servers running? On virtual machines or real machines? 2. Where are glusterfs clients running? On virtual machines or real machines? 3. Is the Xen dom-0 also using glusterfs client? If yes, what all processes are accessing the glusterfs mount. 4. If Xen dom-0 hosts the block device images for Xen guest OSes on glusterfs mount, then what is the access method for guest OSes? loopback (disk=['file:']) or blktp (disk=['tap:aio:']) or nfs rexport? Detailed description of your Xen setup in addition to answers to above questions will help us debug the problem. -- Gowda
