Hello, I've got a new gentoo box with two drives that i'm using raid1 on. On boot the md raid autodetection is failing. Here's the error i'm getting:
md: Waiting for all devices to be available before autodetect md: If you don't use raid, use raid=noautodetect md: Autodetecting RAID arrays. md: Scanned 4 and added 4 devices. md: autorun ... md: considering sda3 ... md: adding sda3 ... md: sda1 has different UUID to sda3 md: adding sdb3 ... md: sdb1 has different UUID to sda3 md: created md3 md: bind<sdb3> md: bind<sda3> md: running: <sda3><sdb3> md: personality for level 1 is not loaded! md: do_md_run() returned -22 md: md3 stopped. md: unbind<sda3> md: export_rdev(sda3) md: unbind<sdb3> md: export_rdev(sdb3) md: considering sda1 ... md: adding sda1 ... md: adding sdb1 ... md: created md1 md: bind<sdb1> md: bind<sda1> md: running: <sda1><sdb1> md: personality for level 1 is not loaded! md: do_md_run() returned -22 md: md1 stopped. md: unbind<sda1> md: export_rdev(sda1) md: unbind<sdb1> md: export_rdev(sdb1) md: ... autorun DONE.

Thanks. Dave.
