How to export a NFS share with these options - *(rw,sync,anonuid=1111,anongid=1111,all_squash)

please see the VNX file reference manual or the NFS pdf manual available from support.emc.com

or "man server_export"

Thanks for your reply.

I did look at "Configuring NFS on VNX" & "VNX® Command Line Interface Reference for File" which has man of server_export before posting this query.

In the manpage of server_export, I see the following in "option" section -

     anon=

     If a request comes from an unknown user, the UID should be used

     as the effective user ID. Root users (UID =0) are considered

     "unknown" by the NFS server unless they are included in the

     root option. The default value for anon= is the user

     "nobody". If the user "nobody" does not exist, then the value

     65534 is used.

     Caution: Using anon=0 is not recommended for security concerns.

But I do not see any reference of group-id.

Also, I could figure anything for "sync" and "all_squash" NFS options.

It will be very helpful if you give me some guidance on this matter.

there is no anongid option or all_squash available on VNX

we dont have an async option - so its always sync

Thanks for your reply.

When I use "server_export server_2 -Protocol nfs -option anon=1111,rw=10.10.10.10/21:10.10.10.11/21 /NFS_for_my_App", my application is complaining that NFS server exposed uid:1111 and gid:0.

Is there a workaround by which I can export the NFS shared with gid=1111. My app is expecting a NFS share exported with that gid?

not on our (NFS server side)

you could try:

- remapping gid on the NFS client

- use the setgid bit on the directory - that will make a files created there owned by the same group as the dir

- change VNX to Unity - next Unity OE version will have a anongid option available

- change your app
