I'm trying to setup a diskless configuration. This is what I have done so far:
torsson.dmj.nu (192.168.1.3) is the dhcp/tftp/NFSv4-server
abba.dmj.nu (192.168.1.14) is the diskless client
In /etc/dhcp/dhcpd.conf I have the following for the "client" (among other
things):
# PXE-Boot, abba
option option-150 code 150 = text ;
ddns-update-style none ;
host abba {
hardware ethernet 00:90:dc:07:6e:a7;
fixed-address 192.168.1.14;
filename "/abba/boot/pxelinux.0";
}
And in pxelinux.cfg/default I have the following:
label Diskless Gentoo root in NFS
kernel bzImage
append root=/dev/nfs ip=dhcp init=/bin/sh
nfsroot=192.168.1.3:/diskless/abba
The kernel (bzImage) loads OK but when it tries to mount the NFS-root I get the
following:
"Root-NFS: Server returned error -13 while mounting /diskless/abba"
And on the server I see this in syslog:
"rpc.mountd[6772]: refused mount request from 192.168.1.14 for /diskless/abba
(/): not exported"
This is how my filesystems are mounted ad exported:
torsson# grep diskless /etc/fstab
/dev/vg00/lvol11 /var/diskless reiserfs noatime
0 2
/var/diskless/abba /export/diskless/abba none rw,bind 0 0
torsson# mount | grep diskless
/dev/mapper/vg00-lvol11 on /var/diskless type reiserfs (rw,noatime)
/var/diskless/abba on /export/diskless/abba type none (rw,bind)
And this is a part of the /etc/exports
/export *(ro,fsid=0,insecure,no_subtree_check,sync)
/export/diskless/abba
abba.dmj.nu(rw,nohide,insecure,no_root_squash,no_subtree_check,sync)
I also have other FS exported like this e.g.:
torsson# grep dan /etc/fstab
/dev/vg00/lvol05 /home/dan reiserfs noatime 0 2
/home/dan/tmp /export/Queen/tmp none rw,bind 0 0
torsson# mount | grep dan
/dev/mapper/vg00-lvol05 on /home/dan type reiserfs (rw,noatime)
/home/dan/tmp on /export/Queen/tmp type none (rw,bind)
And in exports:
/export *(ro,fsid=0,insecure,no_subtree_check,sync)
/export/Queen/tmp
queen.dmj.nu(rw,no_root_squash,nohide,no_subtree_check,async)
And this "client" can mount the export:
queen# grep torsson /etc/fstab
torsson.dmj.nu:/Queen/tmp /home/dan/tmp_torsson nfs4
proto=tcp,soft,intr 0 0
queen# mount | grep torsson
torsson.dmj.nu:/Queen/tmp on /home/dan/tmp_torsson type nfs4
(rw,proto=tcp,soft,intr,addr=192.168.1.3,clientaddr=192.168.1.11)
Any idea why the diskless client can not mount it's root-FS?
