Kdyz se pokousim vytvorit filesystem, tak to skonci s podivnou hlaskou o
"bad magic number". Viz. nize.

[root at accontrol /home/accontrol/www]# newfs -U -O2 /dev/da0s1d

cg 0: bad magic number

Na jinem hardwaru mi to funguje, ale jeste to jednou poradne vyzkousim.
Netusite nekdo v cem by mohl byt problem?

Predem diky,
David.
