Description Johan Hedin 2006-01-10 07:00:42 UTC
Using EVMS craches my HP xw4300 and our HP nx8300. We have tried

Gentoo sources 2.6.14-gentoo-r5 (and some of the below also with 2005.1r1):
evms + BBR + lvm2 + XFS
evms + MD + XFS
evms + BBR + MD + XFS
evms + BBR + MD + LVM2 + XFS
evms + BBR + MD + LVM2 + XFS (on USB discs)

Vanilla sources + BBR 2.6.14.2:
evms + BBR + MD + LVM2 + XFS

Sometimes a kernel panic. Most often just har lockup with no reactor to keybord. Once a reboot. I have two systems at home, one old IBM running EVSM + BBR + LVM2 + XFS and one ASUS P4P800 running EVMS + XFS working without problem. These machines are installed with 2005.0 and upgraded to latest gentoo kernel.

EVMS + XFS as compability volume works.

We also always gets the minimal md reconstruction speed. I don't know if this is related.

Pure md without evms gives high reconstructions speeds
Comment 5 Johan Hedin 2006-01-13 05:50:48 UTC
Setting kernel stack size 8k did remove the problem.
Comment 6 Daniel Drake (RETIRED) gentoo-dev 2006-01-20 15:52:25 UTC
Do you think you could test the latest development kernel (currently 2.6.16-rc1) and see if 4k stacks work ok there? I know there has been work to reduce stack consumption on storage chains like this, but it would be useful to report the issue if it is not completely fixed.
