Severity: normal
Hi all,
Desperating that lvm will ever offer the 'encapsulation' of /boot in lvm like
hpux does), i am trying to install a more common lvm+raid1 boot disk with
following scheme:
boot disk will be build on raid1 + lv, i.e:
o the / (aka root), /boot, swap will be purely raid1
(as recommended)
o the rest /home, /var, /tmp will be in LVs over raid1
(to get benefit of resizing LVM facilities)
ps: raid1 base is still necessary because against announces
LVM is not yet able to manage its own raid1 stuff ;-(
Additional data (/Develop, /Sources, /DebApt, /MultiCd, ...) will stand
on LVs over a software raid5 array of 6*4Gb disk (i.e. 5 + 1 spare)
New Boot disk slicing:

LVM2 filter configuration
-------------------------
in /etc/lvm/lvm.conf
comment all filter and add a custom one to accept only /dev/md/*:
# Custom: only /dev/md/* ;-)
filter = [ "a|/dev/md/*|", "r/.*/" ]
# pvcreate /dev/md/more_root
Physical volume "/dev/md/more_root" successfully created
# vgcreate vg00 /dev/md/more_root

# lvcreate -L 128M -n /dev/vg00/lv_tmp

Creating FS (swap + ext3)
=========================
# mkswap /dev/md/swap
(why not activate it and check)
# swapon /dev/md/swap
# swapon -s
# mke2fs -j /dev/md/boot
# mke2fs -j /dev/md/root
# mke2fs -j /dev/vg00/lv_var
# mke2fs -j /dev/vg00/lv_tmp
# mke2fs -j /dev/vg00/lv_home
# mke2fs -j /dev/vg00/lv_src
Everything was mounted successfully and a copy of my running system is now
finished.
No familiar with initramfs, I prefer to try first without this.
I temporaly use some work-around to reboot the stuff:
adding following line to links.conf:
M md0 b 9 0
M md1 b 9 1
M md2 b 9 2
M md3 b 9 3
M md4 b 9 4
D md
M md/0 b 9 0
M md/1 b 9 1
M md/2 b 9 2
M md/3 b 9 3
M md/4 b 9 4
M md/boot b 9 0
M md/swap b 9 1
M md/root b 9 2
M md/more_root b 9 3
M md/raid5 b 9 4
:-)
All seems ok after that but now encountered some anoying trouble at shutdown:
