[linux-lvm] FWD: Re: Linux Alpha port: LVM



Is LVM working on the alpha port 2.6 kernel series ?
works fine for me.

Are you using a redhat based distro (like suse, mandrake, alpha core or indeed redhat )? Are you using stock kernel, libraries and tools or did you haveto build them yourself ? Debian comes with LVM1 tools that do not work with 2.6 kernels so I need to compile them myself or install some ready build binary package for alpha processor and compatible with the libraries that come with debian3. What alpha architecture are you running on ?


If so where do I get libdevmapper so that I can build the userspace LVM utils ?

I tryied downloading ftp://sources.redhat.com/pub/dm/multipath-toolsmultipath-tools-0.4.3.tar.bz2

what do you think the 'dm' in that url stands for, hm?



But I fail to compile it so I'm also unable tu build the userspace lvm utils.


'userspace lvm utils' can be found here:

ftp://sources.redhat.com/pub/lvm2

multipath tools might be something different ... :)

It may also have something more but it has libdevmapper in it ... In any case I also tried downloading and compiling device-mapper.1.00.07.tgz from the link in the LVM2. It builds and installe fine but I still get compilation errore when I build LVM2. Configute is fine, here are a few lines concerning libdevmapper

checking libdevmapper.h usability... yes
checking libdevmapper.h presence... yes
checking for libdevmapper.h... yes

but when I try to compile:

gcc -c -I. -I../include -DLVM1_INTERNAL -DPOOL_INTERNAL
-DCLUSTER_LOCKING_INTERNAL -DSNAPSHOT_INTERNAL -DMIRRORED_INTERNAL

I'm using kernel 2.6.11.7 downloaded from kernel.org.
Here's the relevent section for raid/lvm in config:
# Multi-device support (RAID and LVM)
#
CONFIG_MD=y
CONFIG_BLK_DEV_MD=y
CONFIG_MD_LINEAR=y
CONFIG_MD_RAID0=y
CONFIG_MD_RAID1=y
# CONFIG_MD_RAID10 is not set
CONFIG_MD_RAID5=y
# CONFIG_MD_RAID6 is not set
CONFIG_MD_MULTIPATH=y
CONFIG_MD_FAULTY=y
CONFIG_BLK_DEV_DM=y
# CONFIG_DM_CRYPT is not set
# CONFIG_DM_SNAPSHOT is not set
# CONFIG_DM_MIRROR is not set
# CONFIG_DM_ZERO is not set

Do I need to patch kernel ?
