Bug Description

When running drbd on top of a software-raid device (mdadm) you get this message:

drbd0: local disk flush failed with status -5

After doing some research i found that this is caused by the 2.6.24 kernel: http://www.nabble.com/local-disk-flush-failed-with-status--5-td16127326.html

A patch/fix is also available at that URL.

I am running kernel 2.6.24-15-server with Ubuntu Hardy 8.04 beta (32-Bits).

A solution for this bug would be to get the newer code from the upstream from kernel.org or apply the patch as stated above.

Hi Wido,

I'm just including the upstream git commit id and description you've referenced. Unfortunately the kernel is currently frozen for Hardy so this probably won't make it in before Hardy final is released. However, this fix will automatically be available in the Intrepid Ibex 8.10 release and this could possibly be considered for the Hardy 8.04.1 point release. I'll reassign to the kernel team for their consideration. Thanks.

I can confirm this. It *should* be fixed in Hardy too.

Yes. On Monday I'll boot up patched kernel and provide a patch after
it, if it works well.
