[Gluster-users] Geo-replication: Entry not present on master. Fixing gfid mismatch in slave

Hi Strahil,

Is there a trick to getting the .gfid directory to appear besides adding
"-o aux-gfid-mount" to the mount? I mounted it using "mount -t glusterfs -o
aux-gfid-mount cafs30:/gvol0 /mnt/glusterfs" and there's no .gfid directory
under /mnt/glusterfs.

I haven't tried joining a gluster meeting. Are bugs/problems usually
discussed on such things? I usually find that people need to look into
things and respond in their own time so email can be better.

Thanks for your help.
