I am trying to set up PXE booting for a bunch of diskless clients using SuSE 11.3. The PXE part is fine - DHCP is functioning properly and the client retrieves the kernel and initrd just fine. It starts booting and eventually dies with this error:
VFS: Cannot open root device “/dev/ram0” or unknown block(0,0).
Please append a correct “root=” boot option; here are the available partitions: <none listed>
Here is the relevant supporting info:
initrd: created from a super-basic install of SuSE 11.3 onto an almost identical machine. fstab and some other files were then edited for the image.
hardware: This is a Dell “DCS23” which is basically a stripped down Poweredge 1950 III
cat etc/fstab /proc /proc proc defaults /dev/ram0 / ext2 defaults
ls -al dev/ram* brw-rw---- 1 root disk 1, 0 Jan 26 15:21 dev/ram0 brw-rw---- 1 root disk 1, 1 Jan 26 15:21 dev/ram1
pxelinux.cfg/default prompt 1 default linux timeout 1 label linux kernel vmlinuz append initrd=/rootfs.gz ramdisk_size=1000000 root=/dev/ram0
None of these machines by default come with the /dev/ram* nodes - I had to create them. I am not sure if that’s the problem or not though but it seems weird that they aren’t created by default.
I can’t find anything else on the web and I can’t really think of any other ideas on how to solve this. Can anyone suggest anything for me to try?
