NFS serer weirdness

[Matt Douhan]

Hello

I am running a STABLE NFS server as follows

9:28am mdouhan @ [rabarber] ~ > uname -a
FreeBSD rabarber.internal.hasta.se 4.9-STABLE FreeBSD 4.9-STABLE #3: Sat Dec 
20 17:25:35 CET 2003     root at rabarber.internal.hasta.se:/usr/obj/usr/src/
sys/RABARBER  i386
9:28am mdouhan @ [rabarber] ~ >

From this server I mount  NFS filesystems from a STABLE machine as follows

9:29am mdouhan @ [mandarin] ~ > uname -a
FreeBSD mandarin.internal.hasta.se 4.8-STABLE FreeBSD 4.8-STABLE #0: Sat Apr  
5 17:07:20 GMT 2003     root at mandarin.internal.hasta.se:/usr/obj/usr/src/sys/
MANDARIN  i386
9:29am mdouhan @ [mandarin] ~ >

using the following line in /etc/fstab

9:29am mdouhan @ [mandarin] ~ > cat /etc/fstab | grep rabarber
rabarber:/net/rabarber  /net/rabarber   nfs     tcp,rw,nfsv3    0       0
9:29am mdouhan @ [mandarin] ~ >

I also mount this NFS filesystems on a CURRENT machines as follows

9:30am mdouhan @ [ananas] ~ > uname -a
FreeBSD ananas.internal.hasta.se 5.1-CURRENT FreeBSD 5.1-CURRENT #0: Wed Nov 
19 19:55:50 CET 2003     root at ananas.internal.hasta.se:/usr/obj/usr/current/
sys/ANANAS  i386
9:30am mdouhan @ [ananas] ~ >

using the following line in /etc/fstab

9:30am mdouhan @ [ananas] ~ > cat /etc/fstab | grep rabarber
rabarber:/net/rabarber  /net/rabarber   nfs     tcp,rw,nfsv3            0       
0
9:31am mdouhan @ [ananas] ~ >

all machines are using the fxp NIC at 100Mbps fdx operations, none of the 
machines show any input or outpput errors if I check with netstat -i, they 
are all connected to a single Switch and the switch does not report any 
errors on the ports and also shows that correct speed/duplex has been 
negotiated, I have also tried hardcoding the speed/duplex settings but the 
result is the same

The problem is as follows
9:34am mdouhan @ [mandarin] ~ > tail /var/log/messages
Dec 19 11:53:37 mandarin /kernel: nfs server rabarber:/net/rabarber: not 
responding
Dec 19 11:53:37 mandarin /kernel: nfs server rabarber:/net/rabarber: is alive 
again
Dec 20 21:54:35 mandarin /kernel: nfs server rabarber:/net/rabarber: not 
responding
Dec 20 21:55:49 mandarin /kernel: nfs server rabarber:/net/rabarber: is alive 
again
Dec 20 22:04:24 mandarin /kernel: nfs server rabarber:/net/rabarber: not 
responding
Dec 20 22:04:38 mandarin /kernel: nfs server rabarber:/net/rabarber: not 
responding
Dec 20 22:05:48 mandarin last message repeated 2 times
Dec 20 22:06:04 mandarin /kernel: nfs server rabarber:/net/rabarber: is alive 
again
Dec 20 22:06:04 mandarin last message repeated 3 times
9:34am mdouhan @ [mandarin] ~ >

All machines mounting NFS systems are seing these errors in the log, and it is 
very annoying, anyone have any idea why this is?

Regards

Matt
