229501 2008-06-26 07:05 0000 sys-fs/mdadm init script function does not support partitionable raid arrays. 2008-06-28 16:44:38 0000 1 1 1 Unclassified Gentoo Linux Library unspecified AMD64 Linux RESOLVED FIXED P2 normal --- 1 smallnow@gmail.com base-system@gentoo.org smallnow@gmail.com 2008-06-26 07:05:06 0000 Since 2.6, the partitionable raid array feature changes the raid array naming convention and causes partitionable raid arrays to not get mounted. This is due to bug in init script function file. Specifically, the mknod command does not get handed the right minor device node. I have included a patch that fixes this. I fixed this on my system a few months ago but didn't have time to make a report. Hopefully this patch finds the maintainer of this file. The patch is for the latest unstable version but the changes work for all versions of the file. I noticed that in the most recent version, the mknod command is redirected to /dev/null. If I was using that version when I originally had this bug, I never would have found it. So, with this fix, hopefully there won't be errors from that command, but I removed the redirection because IT IS USEFULL to see the error. See the section titled DEVICE NAMES in man mdadm to verify the correct device naming convention. Its a small section, heres the pertinent info: The standard names for non-partitioned arrays (the only sort of md array available in 2.4 and earlier) are either of /dev/mdNN /dev/md/NN where NN is a number. The standard names for partitionable arrays (as available from 2.6 onwards) are either of /dev/md/dNN /dev/md_dNN Partition numbers should be indicated by added "pMM" to these, thus "/dev/md/d1p2". Reproducible: Always Steps to Reproduce: 1. do something like: echo y\r | mdadm -C /dev/md_d3 -a p -c 128 -v -f -l 0 -n 3 /dev/sd[abc]7 2. make partitions. I have /dev/md_d3p1 /dev/md_d3p2 3. make a file system, reboot. Actual Results: Big error when starting up. I did not save the error. emerge --info for completeness.
