[dm-devel] newbie: Target Length not divisble error

[Heinz Mauelshagen]

Hrm, dmraid-1.0.0.rc11 has the stride size fix in,
which *should* prevent that kernel message to occur.

Can you send me your metadata created with "dmraid -rD" 
for analysis, please ?

Pack the *.{dat,size,offset} files into isw-Hadders-raid0.tar.bz2
before sending.

Regards,
