No, it is not. Cache is about 1-2 GB in size.

Ok, til yet fs storebehind was not known for me.
And the description is kinda ...
It tells me:
fs storebehind
Default store asynchrony is 0 kbytes.

Does this mean, storebehind is off?
If yes, OK, I see I need a 16 GB cache for OpenAFS on that machine or
copy that file via scp to local home on debian server and afterwards
moving into afs space.
