[Gluster-users] Client and server file "view", different results?! Client can't see the right file.

Fri May 20 18:06:25 UTC 2011

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.

Best, Martin

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?

should be present on only 2 bricks. Why is the file present in 4 bricks?. It
should either be present on pserver12&13 or pserver3 & 5. I am not sure why
you are expecting it to be there on 4 bricks.
