In fstab I´m mounting the devices called ad0s1a, ad0s1f etc.. But when I am compiling the kernel with the old wd drivers there is only wd0a wd0b wd0c etc... There is no wd0s1a-h devices. So...the question is...can I mount wd0a, wd0f etc. instead of ad0s1a, ad0s1f etc. when I´m using the wd driver? /Pär To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
