NFS problem

[Minoia]

Hi.
Some servers don't see the export directory by NFS.
showmount doesn't show it.
rpcinfo it's ok.
Thanks,

Hi,
Server A has exported a mount point, which server B can see, but server C can not see ?

Has Server A exported the mountpoint available to all, is the automounter/nfs client running on server C? Has server C imported the mountpoint from Server A?

Check /etc/rmtab on the NFS server (where you ran showmount) and make sure the client server is there.

After showmount produce correct information, you still need to mount the BFS filesystem on you client server

Yes right.
The problem is that server C does not import the mountpoint exported correctly by server A.

File /etc/rmtab is right but when importing the file system appears "Permission denied"

Hi,
1. Are you using root to mount on your nfs client (Server C)?
2. Are you mounting the nfs filesystem to an empty directory with correct permissions ?
3. Are you mounting the nfs filesystem with the correct options - is it exported as read-only or read-write, if read-write the permissions on the filesystem on the nfs server need to be 777 before you can mount on the client.

1) Yes I'm mounting it as root
2) PErmissions are right.

This mountpoint have been mounted correctly since 6 month ago.

I have detected that on server C we have 2 lan (100 Mb eth and 1Gb eth). On one of them there is no problem to mount it but on the other appears the problem.
The problem appear after a networking problem on 1Gb eth network. I tried to restart nfs client, server and core with no results.

Hi,

Please post the contents of '/etc/exports' as well as Server C's IP address by interface.
