I'm running gentoo, udev 124-r1 I cleared all superblocks on all devices I raided, and undid all the partition tables, and started from scratch, putting the filesystem on the raid devices themselves instead of partitioning the raid devices. Everything is working now, I think it's probably best to keep it simple, or use LVM MD is referenced in the udev config files, but everything is working now. Sorry, I think it was user error. :) Thanks Dylan On Thu, Dec 18, 2008 at 3:06 PM, NeilBrown <neilb@xxxxxxx> wrote: > On Fri, December 19, 2008 12:08 am, Dylan Taft wrote: >> I may give that a shot. >> >> But it also looks like my major numbers are wrong on the actual device >> nodes? >> brw-r----- 1 root disk 9, 0 Dec 17 19:13 0 >> brw-r----- 1 root disk 259, 0 Dec 17 19:13 1 >> brw-r----- 1 root disk 259, 1 Dec 17 19:13 2 >> brw-r----- 1 root disk 259, 2 Dec 17 19:13 3 >> >> Shouldn't this be 9,something, not 259? >> >> If I change the partition type from fd to something else, and don't >> allow the kernel to auto assemble, then assemble manually via mdadm, >> things work right. >> Any idea what could cause thee major numbers to be wrong? > > Almost certainly some udev configuration going wrong. > What distro are you running? > Is there are file in /lib/udev/rules.d or /etc/udev/rules.d with 'md' > in the name?
