Hi,
I have a HA NFS server setup, but I am having some problems with
mounting the NFS shares. I have had to patch mountd to allow it to be
configured with an IP to bind to, its a bit of quick hack (no docs,
ipv6 etc...) but solves the problem for us where mountd sends the
packets from the wrong ip. (See patch bellow).
The NFS server IP is 172.31.0.200 and we have the following flags set in
rc.conf:
nfs_server_flags=-u -t -n 4 -h 172.31.0.200
rpcbind_flags=-h 172.31.0.200
mountd_flags=-r -p 832 -h 172.31.0.200
When I try and mount the share I get the following error the command:
maverick# mount nfs-server:/usr/home /usr/home
[udp] nfs-server:/usr/home: RPCPROG_MNT: RPC: Timed out
[udp] nfs-server:/usr/home: RPCPROG_MNT: RPC: Timed out
And the following data from tcpdump on the server:
[EMAIL PROTECTED] /usr/home/mintel]# tcpdump -n 'ip host 172.31.0.2 and ip
host 172.31.0.200'
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

I can reproduce the problem on a number 6.2 Release systems (i386/amd64).
Has anyone seen this before, or know of a fix?
Thanks
Tom
