There's no indication this is a(n upstream) kernel bug, marking that task invalid. |

I have just installed jaunty with a separate boot partition and / on a raid10 array (/dev/md1).
However when I boot, I'm dropped in a initramfs shell and I have to manually assemble the array as all disks are marked as spare. There are also segfaults in dmesg. mdadm[1370]: segfault at 0 ip 000000000040839b sp 00007fffb2af2620 error 4 in mdadm[400000+2a000] |
I have just installed jaunty with a separate boot partition and / on a raid10 array (/dev/md1).
However when I boot, I'm dropped in a initramfs shell and I have to manually assemble the array as all disks are marked as spare. There are also segfaults in dmesg. mdadm[1370]: segfault at 0 ip 000000000040839b sp 00007fffb2af2620 error 4 in mdadm[400000+2a000]
The segfault is easily reproducable; steps to do so:
1) create 4 empty loopback disks:
for i in $(seq 1 4) ; do
dd if=/dev/zero of=disk${i} bs=1024 count=512000
sudo losetup /dev/loop${i} disk${i}
done
2) create raid10 array
sudo mdadm -C /dev/md0 -l raid10 -n 4 /dev/loop{1,2,3,4}
3) stop the array:
sudo mdadm --stop /dev/md0
4) incrementally assemble the first loop device; this is how udev invokes mdadm in /lib/udev/rules.d/85-mdadm.rules.
sudo mdadm --incremental /dev/loop1
et voila, segv. |

The segfault is easily reproducible on jaunty without needing to do a full install on a raid10 setup; steps to do so:
1) create 4 empty loopback disks:
for i in $(seq 1 4) ; do
dd if=/dev/zero of=disk${i} bs=1024 count=512000
sudo losetup /dev/loop${i} disk${i}

Documented in the Beta technical overview:
The mdadm package in Ubuntu 9.04 Beta will fail to assemble RAID10 arrays on boot. Other types of RAID are not affected; investigation of this issue is ongoing.
This is a high-priority issue which should be fixed for release, so I don't expect we'll need to document anything in the release notes. |
