nfsd daemons and

threads

• What are they?

• How do they work in the

READ and WRITE cases?

• Why are more nfsds

launched than configured

in NUM_NFSD?

• How many threads service

TCP requests?

• How many nfsds should

you run?

• Troubleshooting

This section discusses the various daemons and threads that handle server-side NFS

requests. It describes how these daemons and threads work in both the read and

write scenarios. It explains how they work differently when servicing NFS/UDP

requests vs. NFS/TCP requests. It also covers the various factors involved in

selecting the appropriate number of nfsd daemons to run on a given server.

Finally, it describes the tools and methods available for troubleshooting nfsd and

nfsktcpd problems.
