Subject[biocenter.helsinki.fi #2456] LVM2 problems with device mapper
Date
Hello,

I'm trying to upgrade a machine to the 2.6.4 kernel. I have a problem
with LVM, though, and it's preventing me from getting anywhere with this.

I've installed the LVM2 kit v2.00.08.

I've built the device mapper as a module. The module loads without any
problems. I am not using devfs, so I ran the devmap_mknod.sh script to
create the /dev/mapper/control device, which became c 10 63.

After this, running vgscan --mknodes finds the existing volume groups
with LVM1 metadata, but complains about not being able to access the
mapper control device.

Running vgchange -a y complains about not being able to access the
mapper control device and fails altogether.

I also tried rebuilding the kernel with the patches from
http://people.sistina.com/~thornber/patches/. The device mapper module
version changed from 4.0.0 to 4.1.0. No new error messages, but still
no functionality either.

If it's of any consequence, the machine is a Fujitsu-Siemens RX800 8-
way with the IBM Summit x440 chipset. Support for the Summit x440 has
naturally been enabled in the kernel.
