|0006112||CentOS-6||dracut||public||2012-12-03 18:20||2012-12-03 18:20|
|Target Version||Fixed in Version|
|Summary||0006112: NFS or LiveNet Functionality Not Working Correctly with Dracut|
|Description||I am trying to create a new initrd to support booting diskless machines over the network. The DHCP/TFTP configuration is working as intended. The client gets and IP address and is able to download the initrd file and vmlinuz.|
The problem appears when attempting to mount the root filesystem on the client. I have tried to use both the livenet module and nfs, but an error appears saying:
"don't know how to handle root=nfs (or root=live)"
I even tried downloading the newest version of dracut (024) and still experience this issue.
|Steps To Reproduce||1. Setup DHCP/TFTP server to lease addresses. |
2. Installed appropriate dracut RPMs (dracut, dracut-network) using Yum.
3. Ran the following command to make the initrd
dracut -v --force -a "livenet nfs" initrd.img
4. Configured /var/lib/tftpboot/linux-install/pxelinux.cfg/default to contain the following
append initrd=initrd.img root=nfs:<serverip>:/exports/root rw
I also tried the folowing for the livenet module
append initrd=initrd.img console=tty0 rd.shell rd.debug root=live:http://<serverip>/squashfs.img [^] rw
5. Created the /exports/root filesystem to include the base packages for CentOS
yum --releasever=6 groupinstall Base --installroot=/exports/root
6. Exported this via /exports/root via NFS
7. Squashed it to try with the livenet module
mksquashfs /exports/root /var/www/html/squashfs.img -e /var/www/html
|Additional Information||I even tried uninstalling the version of dracut that is installed with CentOS and installing dracut 024 (including the network modules), but this did not make a difference.|
At this point, I'm trying anyway to create a diskless system to boot over the network. If there is another way (besides dracut), let me know.
