Oky, on the other hand,,;
this only get stranger... i can access the raid with dd.. but watch this:


vserv:~ # cat /etc/raidtab

i can do a dd to /dev/fr10 here but anything else reports that the device i 0-blocks...

btw: i know i load the same code that i compile, else i would not different major's when i recompile with different major in the .h file..
