Zdravim vas, nevim proc, ale vcera nam spadl ubuntu server a po startu to vypsalo:

hledal jsem navody jak to opravit, ale bohuzel , bez kladneho vysledku.

Stahnul jsem si liveCD ubuntu a nabootoval jsem ho.

opak jsem zjistil, ze mam rozbity raid a tak jsem jej opravil pomoci:

sudo apt-get update
sudo apt-get install mdadm

mdadm --assemble --scan

coz provedlo scan a sloucilo mi to ty raidy.

no ale ted nevim jak dal.

kdyz jsem dal fdisk tak mi to vypslo toto:
