[linux-lvm] Testing LVM2

[Nils Juergens]

Hi,

i'm currently in the process of starting to test the 2.5 linux kernel
series, now that the 2.6-pre are around the corner. While i'm at it and
having set up a box completely for testing (and trying to break) stuff 
i thought i might give lvm2 a try (not that i expect it to break :) ).

Thus, i got LVM2.2.00.03-rc4.tgz and device-mapper.1.00.02-rc3.tgz of the
ftp server.

My question is: Is this stuff supposed to work with the 2.5 kernel series or
do i have to switch to 2.4 to test lvm2? I know that the device-mapper is
included in the 2.5 series, but is it recent enough? Also, are there
different (and thus incompatible) versions of either the device mapper
and/or the device-mapper-libs around?

Trying to compile the above device-mapper after doing

configure --with-kernel-dir=/usr/src/linux-2.5.75

i get (using gcc-3.3 from Debian unstable):

[snipped other make output]
