switch to initramfs (11.07 KB, patch)

Description Bernie Innocenti 2006-09-01 00:28:54 UTC
I'm not sure if this is a bug in the kernel, pxeboot, tftp or
system-config-netboot.

The symptom is that diskless clients panic during boot
with this error message:

 RAMDISK: Compressed image found at block 0
 EXT2-fs: blocksize too small for device.

The initrd image on the server looks good: it's a valid gzip file containing a
valid ext2 image that mounts with loopback.  The ramdisk_size kernel parameter
matches the uncompressed image size.

The client kernel is 2.6.17-1.2600.fc6 (x86_64)

The pxeboot command line is:

label 2
    kernel fedora-x86_64/vmlinuz
    append  initrd=fedora-x86_64/initrd.img root=/dev/ram0 init=disklessrc
NFSROOT=10.3.3.1:/diskless/x86_64/fedora ramdisk_size=28086 ETHERNET=eth0

append ramdisk_blocksize=1024 in your pxe cfg

I've updated the system-config-netboot scripts to use initramfs and cpio.

Anyone wants the patches?

switch to initramfs

This patch changes updateDiskless to build a
new style cpio archive for initramfs instead
of the old initrd filesystem image.

Lots of changes (actually simplifications) are needed in
the init script to use switch_root instead of pivot_root.

Thanks for patch, it's was applied in version 0.1.42.
