xfs + raid5

[Jan Hradil]

 Zdravim,

obcas se mi stane, ze mi pod rukama zmizi filesystem (ls neukazuje zadne
soubory, adresare). V logu jsou divne veci - nejdriv hlasky od raidu (ty
mi prijdou divne, ale zda se ze relativne neskodne) [vi nekdo, co to
znamena a jestli je to opravdu neskodne?]. 

 A kdyz zmizi fs, tak se objevi hlasky xfs*. Vite nekdo co s tim?

Diky,

Honza
