Help: About NFS

Hello,

O'm a Linux user, and I built a small LAN in my home. I use one machine to
be a NFS server, but I'd like to know what's the meaning of "nfs-lock"
service?

My Linux system is Redhat 9.

Thanks in advance~

Hi

It provides file-locking services over NFS, so that one client requesting a
lock is coordinated with other clients trying to lock the same file.

Why it is a separate daemon on NFSv2/3 involves history.

It can be ignored in special cases, by mounting the nfs export with

-onolock

which usually only makes sense if mounting the filesytem read-only as well.
