Hi Lala,
Photoshop will throw errors in its GUI along the lines of "this file
is already open". Microsoft Excel does similar things. I'm sorry for
the terse details at this point.
At one point I investigated this a lot more thoroughly with
tcpdump/wireshark in the middle and more verbose/debug level errors
from Samba's side, but I've since deleted all of those outputs.
Hopefully things will quieten down for me in late March. If it does,
I'll get recent versions of GlusterFS, Samba and vfs_glusterfs all up
and running and re-test the whole lot again in a more thorough and
reproducible manner with better notes attached. Anything I find I'll
submit to the list and to the Gluster bug tracker. I'm just in the
middle of preparing for a few large projects at the moment, so my time
is short, sadly.
