hmm, the man page seems to be out of date. On my diskless client
swapinfo works flawlessly:
broccoli:~$ swapinfo
Device 1K-blocks Used Avail Capacity Type
[NFS swap] 130944 0 130944 0% Interleaved
broccoli:~$ uname -r
4.8-STABLE-20030510-JPSNAP
Also, I don't get that error or warning message at boot time:
subnet mask 255.255.255.0 router 192.168.43.1 rootfs \
192.168.43.1:/exports/root/broccoli rootopts nfsv3,udp,hard \
swapfs 192.168.43.1:/exports/swap swapopts nfsv3,udp,hard \
hostname broccoli
Adjusted interface xl0
md_lookup_swap: Swap size is 131072 KB
Mounting root from nfs:
NFS ROOT: 192.168.43.1:/exports/root/broccoli
NFS SWAP: 192.168.43.1:/exports/swap
For DHCP I use these vendor options:
option freebsd-swap-path code 128 = text;
option freebsd-swap-opts code 130 = text;
option freebsd-root-opts code 131 = text;
All diskless clients share these DHCP config:
use-host-decl-names on;
filename "pxeboot";
option freebsd-swap-path "192.168.43.1:/exports/swap";
option freebsd-swap-opts "nfsv3,udp,hard";
option freebsd-root-opts "nfsv3,udp,hard";
The root path is set per individual client of course.
Maybe this helps.
