Hi,
What did I miss / do wrong? My config didn't work like on the
below linked video:
http://www.samba.org/~tridge/ctdb_movies/node_disable.html
With my config, the copy process fails/breaks despite that the
tesztxp PC successfully maps the other (samba) PC in case the
first (samba) PC is out. In the samba logs (even at log level = 10)
I didn't see any information that can help me solve this problem.
Please help me to find the error in the above config or suggest
one, that actually works.
