Dotaz: Rozbitie softveroveho RAIDu

[dusan]

Ako najjednoduchsie a narychlejsie (co najmenej restartov) prejst od softveroveho RAIDu k normalnym particiam?

$ cat /proc/mdstat

• boot z livecd
• z poli udelat degradovana (vyhodit po jednom zarizeni z mirroru - idealne vynulovat MD superblok)
• na zarizenich vyhozenych z pole vytvorit FS - idealne mezi partitions a FS dat jeste LVM - bude se hodit v mnoha situacich (napr. az budete priste zase presouvat na RAID )
• presunout data z MD na nova FS (se zachovanim vlastnika, prav, apod. - napr. pomoci rsync)
• poresit bootloader
• upravit fstab
• pripadne pregenerovat initramfs
• reboot

VMware vCenter Converter (na prevod fyzickeho stroja na virtualny) nezvlada na zdrojovom systeme softverovy RAID.

Converter Standalone 4.0 does not recognize source volumes that reside on Linux Software RAID configurations
During cloning of powered-on Linux machines, Converter Standalone does not recognize source volumes that are part of a Software RAID configuration (also referred to as multiple disk, or md, configurations).
