I've been trying to set up a raid0 and raid1 array on a sparc linux
box. I was able to build raidtools 0.41 and can initialize the array for
raid1. Every time I go to mdadd the devices I get the /dev/md0: Invalid
argument for the madd , or mdrun command. I rebuild the raidtools and
did the make install_dev at least twice. No change. I retryed on a SS5
running kernel rls 2.1.127 and 2.0.35 , a little bit better. the error
messages is /dev/sdb1 /dev/sdc1 busy. Do you have any clues to what is
going on?
Also is their some detailed information to all of the options
available with the raidtools-0.50 raidstart? The man pages on gives
syntax but no good options.
