should map old LVM syntax (/dev/vgname/lvname) syntax to devmapper

[Eduard Bloch]

Hello,

after making few modifications on an Ubuntu systems and installing a new kernel,
the thing failed to boot. I realized that the problem was caused by the new kind
of initrd images created by mkinitramfs. I took me some time to understand what
is going on because the error messages are not helpful at all. The reason was
that I have beeing using the old syntax for the root fs, /dev/vgname/lvname, but
this breaks with the script used in the initramfs. Please make it get the root
name also from the /dev/vgname/... strings and not expect
/dev/mapper/vgname-lvname only.

Hi Eduard,

Do you still have this issue when installing a new kernel on Dapper Beta?

Thank you for reporting this bug.

I am not sure, I don't usualy reboot that machine. In theory, it is quite easy to fix. The maintainer of initramfs-tools should know when he/she has dealt with the problem.

Hi,

i still had that issue with a brandnew 6.06 LTS X86_64 installation. The script
lvm starting at line 18:
---
vg=${ROOT#/dev/mapper/}

case ${vg} in
        /dev/root)
                unset vg
                ;;
        /*)
                exit 0
                ;;
esac
---

leads to the issue. if i comment that out and create a new initrd it works flawlessly. I dont know if you want to call vgchange -a y only if rootdev is on lvm? Is it for performance issue?

Setting new style syntax solves the problem, but i did not find a documentation that new style syntax is needed.

Regards, Joerg

Thank you for reporting this bug.

Does this occur in Lucid?

It seems likley that this is now resolved following the change to lvm2. Please reopen if it persists in wily.
