Hi, I have a weird behaviour concerning my nfsroot configuration.
If I use a kernel 3.X (3.16.0-6-amd64) created with another fai server, my clients boot fine, but if I try to create a kernel 4.9.0-8, my clients are always stuck in a "read only file system" error ( The exact error message is the same than this one: https://lists.uni-koeln.de/pipermail/linux-fai/2008-January/005648.html ), although my nfs configuration and the disks are the same. I had also another boot behaviour on some other clients: it is just loading vmlinuz + initrd and then, nothing, just a black screen with no warn/error message. Though, the creation of the nfsroot seems to be Ok (no error or warning in /var/log/fai/fai-make-nfsroot.log). I double checked my /etc/fai directory and particularly nfsroot.conf and my NFSROOT file, but these files are the same on both fai servers. I am thinking about a nfsroot option in my pxelinux/tftp file, and my nfs version. However, both servers are listening for nfs version 3 and 4. I found this thread, talking about nfsroot and the nfs versions on bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=922031 My tftp files look like this: # generated by fai-chboot for host 10.1.253.21 with IP 10.1.253.21 default fai-generated label fai-generated kernel vmlinuz-3.16.0-6-amd64 append initrd=initrd.img-3.16.0-6-amd64 rw aufs ip=dhcp root=/dev/nfs nfsroot=10.1.254.41:/srv/fai/nfsroot:vers=3 rd.shell FAI_FLAGS=verbose,sshd,createvt,reboot FAI_ACTION=install server=faiserver.local FAI_CONFIG_SRC=nfs://faiserver.local/srv/fai/config rd.md=0 rd.dm=0 rd.lvm=0 rd.luks=0 And, yes, I am using root=/dev/nfs and vers=3. WHen, I am using sed to switch to kernel 4.9.0-8 and the corresponding nfsroot, it does not work anymore as described above. Could it be caused by this configuration ? Kind regards, Rémy
