NFS export as ro

Bruce Baillie — Tue, 14 Mar 2006 18:07:37 GMT

I have exported a directory to 10 nodes as rw, now I need to export it to one more as ro. How can I do it?

You need to export it as "read-mostly".

/mydir rw=host1,host2,host3

This will allow host1,host2, and host3 read-write access but any other hosts not explicitly listed will be read-only.

Man exports for details.

If you are using with rw then you don't need to specify (can not) ro to one node. Other nodes which are not configured with rw can access the file system with read-only mode.

Try to mount from the node as,

# mkdir /tmp/testfs
# mount fileserver:/filesystem /tmp/testfs

will work.

PS: Both machines are needed to be reachable through network.

Hi Bruce,

use the follwoing enrty in /etc/exports to make a readonly export,

/directory -ro

optionally, you can give a selective read write access by adding

/directory -rw=hosta:hostb

Siva.

Siva,

Are you asking Bruce to add two entry with ro and rw for one file system? If so it is not possible. Read exports man page.

OK, here is how the exports file looks, and it works.

/dir -rw=node1:node2:node3,access=node4
