dracut not assembling raid 10 sets
Last modified: 2010-08-05 10:07:10 EDT
Description of problem: dracut not assembling raid 10 sets Version-Release number of selected component (if applicable): dracut-006-2.fc14.noarch or kernels after 2.6.35-0.49.rc5.git2.fc14.x86_64 How reproducible: Every time with each kernel update after 2.6.35-0.49.rc5.git2.fc14.x86_64 Steps to Reproduce: 1. boot system 2. 3. Actual results: Boot starts, dracut cuts in but drops to shell with Root partition not found Expected results: Normal boot Additional info: Root partition is on an LV on a raid10 PV. With kernels 2.6.35-0.49.rc5.git2.fc14.x86_64 and earlier, can see the creation of the pv during boot, but do not see the creation after 2.6.35-0.49.rc5.git2.fc14.x86_64. When dropped into a shell, no arrays in dev, so PVSCAN can't find it tho it does find other non-raid PVs. In the shell, I can mdadm --assemble /dev/md127 --uuid=.... and trick a boot, but this is really awkward and I do not consider it a valid workaround when a normal boot should occur. Currently booted into rawhide with 2.6.35-0.49.rc5.git2.fc14.x86_64.

Does this fix your issue? http://harald.fedorapeople.org/downloads/dracut/dracut-007-0.4.gite0c1d4e/ # rpm -Fvh dracut-007-0.4.gite0c1d4e*.rpm # dracut -f # reboot
Created attachment 436551 [details] screenshot of segfault in initramfs segfaults, tho I did see that the md array was assembled just before the segfault. Thanks
ah.. nice.. looks like a solid kernel issue
Fixed with one of the following: kernel-2.6.36-0.0.rc0.git1.fc15 and/or mdadm-3.1.3-0.git20100804.2.fc15 -------------------------------- * Wed Aug 04 2010 Doug Ledford <dledford@redhat.com> - 3.1.3-0.git20100804.2 - Add udev patch to not have incremental assembly in two rules files * Wed Aug 04 2010 Doug Ledford <dledford@redhat.com> - 3.1.3-0.git20100804.1 - Update to latest upstream release (resolves an issue with stale lock files on the md device map file) Closing....
