rpcbind disappeared

[Leon A. Howorth]

Had a recent problem with an NFS server (running HP-UX 11.11) and found that the rpcbind process was not running. All the other processes normally associated with NFS server were up, but the rpcbind had somehow disappeared. I cannot find any indications for its disappearance in /var/adm/syslog/syslog.log. Can anyone suggest where else I can look for clues as to why it stopped running?

Leon,

Check /etc/rpc file if you have the rpcbind line in it:

more /etc/rpc
##
# pragma VERSIONID "@(#)rpc: 11R2-4"
# file of rpc program name to number mappings
##
rpcbind 100000 portmap sunrpc rpcbind
rstatd 100001 rstat rup perfmeter
rusersd 100002 rusers
..............

It's possible that rpcbind may have crashed. If that's the case you may want to check if you got the latest NFS General Release/Performance Patch. Take a look at ..
Patch Name: PHNE_28568
One of the symptom .. "rpcbind crashes with signal 10, Bus error (SIGBUS)".

Could you attach the following from the server:

nfsstat -s
nfsstat -rc
netstat -m
netstat -s -p udp
sar -u 5 5
vmstat -n 5 5

[Leon A. Howorth]

I should have mentioned that I was able to start
rpcbind manually. The /etc/rpc file is fine. I do have patch PHNE_28568 as well. I'm attaching the output that Mike Steele requested.

What is in the /etc/rc.log ?
Start NFS core subsystem
Output from "/sbin/rc2.d/S400nfs.core start":
----------------------------
starting NFS CORE networking

starting up the rpcbind
/usr/sbin/rpcbind
starting up the nfskd daemon
/usr/sbin/nfskd

Do you have that?

[Kevin Wright]

Did you do a warm start of rpcbind? Was there an rpcbind.file file in /tmp? Otherwise, you will be forced to restart all of your rpc services after starting rpcbind again.

[Michael Steele_2]

You're going to have to test this under load. So create a large file with 'prealloc' and then copy it back and forth into out of the NFS mounted file system from the client, while reading stats from the server.

prealloc /tmp/500meg 500000000 = 500 mb
prealloc /tmp/5gig 5000000000 = 5 gb
