Ahoj Mam problem s instalaci nebo spise s nabehnutim systemu, chyba bude nejspise v tom ze delam neco spatne pri instalaci a konfiguraci RAID5. Server mam nasledujici http://supermicro.com/products/motherboard/P4/E7221/P8SCT.cfm v nem 4 320GB SATA disky. Insatluju gentoo presne takto krok po kroku. Kdyz jsem to ted nahazoval podruhe (neuspesne) psal jsem si seznam. Do cd jsem vlozil minil live CD velikost neco pres 50MB. Nahodil sitovku pres dhcpcd a postupoval takto: echo zapne podporu raidu
modprobe raid0
modprobe raid1
modprobe raid5
modprobe dm-mod




echo rozdeli disky musi se vlozit rucne
fdisk /dev/sda
