That's why I'm using gluster too. I'm running web servers that allow uploads, and if you're going to maintain a no-stickiness policy for balancing and failover performance, a write followed immediately by a read needs to work across any mixture of servers. That's what's stopping me using other solutions instead of gluster. If only I could get it to work reliably! Marcus
