update-initramfs error

[decibel83]

Hi.

When I run "update-initramfs -u" to update the initramfs image I get this error:

proxmox:~# update-initramfs -u
/boot/initrd.img-proxmox_initrd.img does not exist. Cannot update.

How I can solve this problem?

Thank you very much!
Bye!

we do not support the initramfs tools.

Btw, what do you want to do?

Btw, what do you want to do?

I have to move an existing installation of PVE to a software RAID1 array, so I think I have to rebuild the initrd image with the RAID software support.

Could you help me, please?

 

[dietmar]

Again, we do not support software RAID. We think that LVM2 ontop of MDRAID is to complex to handle.

Ok, don't worry.
Can I only know with what modules did you build the provided initrd.img image (/boot/proxmox_initrd.img), please?

 

[dietmar]

Basically we build/include most modules, but we use hardware autodetection to load modules. If you want to play around you can download:

ftp://pve.proxmox.com/sources/pve-kernel-2.6.24-3.tar.gz

and take a look at the 'init' script - should be easy to modify.

I looked at that script but I didn't found anything interesting for me.
Could you help me to understand what features I have to specify in the /etc/mkinitrd directory to remake the initrd.img to support RAID, please?

 

[dietmar]

Take a look at the initramfs documentation - we don't use initramfs, so i do not know whats needed.

Ok, thank you very much.
What you used to build initrd.img?
Could you help me to rebuild it to support RAID software for the root partition (which is in /dev/md1 in my configuration), please?

 

[dietmar]

There is a perl script called 'create-initrd-dir' shipped with our kernel.

I don't know what needed for MDRAID - i guess you need to include and start mdadm somehow.
