Kernel fails to start due to error size reporting in device-mapper.

[Jacobo S. Arvelo Estévez]

Binary package hint: linux-image-2.6.31-3-generic

When kernel is loading, its fails to mount the root filesystem, its loops reporting that the size of drive is wrong, sda and sdb, this drives are part of a RAID0 device with nForce 630a.

Its works ok with Jaunty 9.04 kernel, but when I upgrade to karmic, it fails with 2.6.31 kernel and I need to load ubuntu with Jaunty kernel.

I attached uname information, karmic with all updates at 17 july 01:42 UTC but with Jaunty kernel.

Here, I attach a photo of the booting process and the loop with same error forever.

[Andreas Simon (andreas-w-simon)]

The same happens here with an Intel ICH8 Raid. Ubuntu itself is not installed on any of the raid drivers (sda and sdb), but raid partitions get mounted later.

This problem is not present in the kernel of Karmic alpha2 (2.6.30), but appeared after the update of the current Karmic kernel 2.6.31-3.

[Andreas Simon (andreas-w-simon)]

For me the issue vanished with linux-image-2.6.31-4-generic (2.6.31-4.22).

During boot there are still these warnings:
Jul 25 12:29:16 vrock kernel: [ 9.259545] device-mapper: table: 252:6: sda too small for target
Jul 25 12:29:16 vrock kernel: [ 9.259547] device-mapper: table: 252:6: sdb too small for target
Jul 25 12:29:16 vrock kernel: [ 9.278195] device-mapper: table: 252:6: sda too small for target
Jul 25 12:29:16 vrock kernel: [ 9.278197] device-mapper: table: 252:6: sdb too small for target

but the boot process doesn't halt anymore after printing these warnings and the system boots up fine.

Me too Andreas, with 2.6.31-4-generic my ubuntu boots up.

Hi Guys,

This actually looks to be a duplicate of bug 398059 so I am marking it as such. If you examine the other bug reporter you'll notice there should have been patches applied to resolve this. Thanks.
