[SOLVED] Can't mount nfs share

I'm trying to mount an nfs share using this mount command and keep getting the following error:

sudo mount -v -t nfs4 wind_server:/srv/nfs4 /nfs/wind   

                         

mount.nfs4: timeout set for Thu Jul 23 21:00:46 2015

Output of showmount -e for the server is:

showmount -e wind_server 

Export list for wind_server:

/srv/nfs4/mnt/Cavalry/Backup 192.168.1.0/24
/srv/nfs4/mnt                192.168.1.0/24
/srv/nfs4/home               192.168.1.0/24
/srv/nfs4                    192.168.1.0/24 

Would appreciate any thoughts on what I'm doing wrong or how to troubleshoot.

Re: [SOLVED] Can't mount nfs share

Hi,

Please show the output (on your NFS server) of the following command:

rpcinfo | egrep "service|nfs"

Re: [SOLVED] Can't mount nfs share

With NFS4 you probably need to work off the export root:

$ showmount -e 199.200.1.110
/srv/nfs4/pub 199.200.1.0/24
/srv/nfs4/bin 199.200.1.0/24
/srv/nfs4     199.200.1.0/24
$ sudo mount -vt nfs4 199.200.1.110:bin /mnt/test
mount.nfs4: timeout set for Tue Aug  4 14:26:18 2015
mount.nfs4: trying text-based options 'vers=4.2,addr=199.200.1.110,clientaddr=199.200.1.140'
$ ls /mnt/test
<stuff in the bin export>

Edit: Also, how have you been around since '07 but not use code tags!?!

Re: [SOLVED] Can't mount nfs share

If you're trying to mount the root NFS dir, try:

sudo mount -v -t nfs4 wind_server:/ /nfs/wind

Re: [SOLVED] Can't mount nfs share

That statement

 sudo mount -vt nfs4 wind_server:/ /nfs/wind 

works!

The problem was how I defined the nfs root. In previous attempts to mount, I was using

 sudo mount -vt nfs4 wind_server:/srv/nfs4/ /nfs/wind 

based on the showmount results, but that was clearly wrong.

Will mark this one solved. Thanks, Painless and alphaniner.
