No, all files are running VMs. No-one alters them manually (which would kill the VM...) So, all was done by the replicate mechanism and the sync. We have to reboot servers from time to time for upgrades, but we do bring the back up with the Gluster running before tackling a second server.

What's more interesting is that pserver3 shows "0" bytes and rest 3 of them show the same "size". While pserver12 & 13 has "trusted.glusterfs.dht.linkto="storage0-replicate-0" set. Was there every any manual operation done with these files? On Thu, May 19, 2011 at 5:16 AM, Pranith Kumar.

It should either be present on pserver12&13 or pserver3 & 5.
