[linux-lvm] lvcreate_initrd & redhat 6.1

[Jonathan S. Polacheck]

Got lvm running on at RH 6.1 after patching a 2.2.10 kernal.  All looking
very good. However, when I ran lvcreate_initrd, it errored out;

[root@l61 tools]# ./lvmcreate_initrd

Logical Volume Manager 0.7 by Heinz Mauelshagen  01/07/1999

lvmcreate_initrd -- this script creates a LVM initial ram disk in
/boot/initrd.z

lvmcreate_initrd -- making ram filesystem
lvmcreate_initrd -- ERROR making ram disk filesystem

Also, any suggestions as to where to put the "vgscan" and "vgchange -a y"
on this system.  It uses the "Sys V" rc.d setup (no /sbin/init.d/boot
file).

Thanks,

Jon Polacheck

Looks like you didn't configure your kernel to support ramdisks.
If you do configure it, don't forget to add initial ramdisk support too.

I'm not used to RedHat but have a look at your /etc/inittab and figure out
what is started at boottime by looking for entries with field 3 containing
"boot" or "bootwait".
Put in vgscan and vgchange into the script started by these
(after root has been mounted rw).

Another solution is (if you want to set up an initrd system with root contained
in an LV anyway) to avoid vgscan and vgchange in the boot script by just
copying the /dev/VolumeGroup/* special files from your initial ramdisk
to your LV based root filesystem.

Hi,

    the script lvcreate_initrd has a typo (-N 4096) in the line :

    mke2fs -m0 -N 4096 $DEVRAM $INITRDSIZE >/dev/null 2>&1

Edit and change to -B 4096 :
    mke2fs -m0 -B 4096 $DEVRAM $INITRDSIZE >/dev/null 2>&1
[]s

No (init) ramdisk support in your kernel.

Into /sbin on the initrd. The script does it for you nicely.
