Subject: What does "mapping=identity" mean in /etc/exports?
Hello -
I'm migrating an old NFS server to newer hardware. /etc/exports in the old environment looks like this:
/shares/IMSHCS01 *(rw,insecure,sync,no_root_squash,all_squash,mapping=identity,anonuid=0,anongid=0
So the old system is exporting the directory, /shares/IMSHCS01 to anyone and everyone who wants to connect, with a bunch of switches essentially making it wide open.
Wonderful.
But on the new system, when I set up /etc/exports the same way, I get this error:
[root at nfs2013 etc]# exportfs -av
exportfs: /etc/exports:1: unknown keyword "mapping=identity"
[root at nfs2013 etc]#
Getting rid of "mapping=identity", my shared directory exports just fine.
I can find no mention of "mapping=identity" in any man pages, but several google references show this option in pasted-in copies of /etc/exports files. My hunch is, this is an obsolete option and no longer supported - but what did it do in case my new server needs to behave the same way the old server behaved?
Thanks
