Dobrý večer přeji Již několik hodin řeším, proč se mi přestaly vytvářen nody pro /dev/sdXY z kterých tvořím přes mdadm sw raid1. Z logů bohužel chytrý nejsem. MD nody jde vytvořit prostřednictvím "mknod /dev/mdXYZ b 9 XYZ" s tím, že posléze vše mountnu pomocí mount -a. Po restartu jsem ovšem zpátky při starém. Přiložené výpisy jsou po aplikaci prozatimní opravy. Kernel 2.6.36-r5 Mdadm 3.1.4 Udev 151-r4 Přikládám pár výpisů:

Jsem si vědom hlášení nesprávného UUID, ale to jsem kontroloval a je v pořádku. Uniká mi detekce počátku jednotlivých particí, ale jsem aktuálně na mrtvém bodu. Děkuji za každý ohlas.
