Re: Kanotix crashed my raid...

[PFC <lists@peufeu.com>]

	I forgot :

	I tried these :

  	mdadm --assemble /dev/md2 /dev/hdb1 /dev/sd{a,b,c,d}1

	with --run, --force, and both, --stop'ping the array before each try, and  
everytime is the same error, and the same line in dmesg : "cannot start  
dirty degraded array for md2"


apollo13 ~ # mdadm --stop /dev/md2
apollo13 ~ # mdadm --assemble --verbose /dev/md2 /dev/hdb1
