1. Verify access to the NFS server

   You can see all exported file systems on the EUMETSAT NFS server without mounting it using the showmount command like in the example below:

   Code Block
   language bash
   karatosun@myfirstvm ~$ showmount --exports 198.18.255.11 Export list for 198.18.255.11: ... (lot of text, but should include) /ifs/data/EUMETSAT_DATA /ifs/data/EUMETCAST ...

   
   

   Info
   If you receive an error (e.g. timeout), please refer to the troubleshooting section below.

   
   

2.  Create the (empty) directory where you'll mount the NFS share

   You can place this anywhere you wish; we have chosen /eumetsatdata in the example here

   Code Block
   language bash
   karatosun@myfirstvm ~$ sudo mkdir /eumetsatdata karatosun@myfirstvm ~$ sudo echo "run sudo mount -a" > /eumetsatdata/NFS_NOT_MOUNTED # put a placeholder file in the directory to make it clear what's (not) happened karatosun@myfirstvm ~$ sudo chmod a+rX,go-w /eumetsatdata # minimise write permissions to prevent mistakes if the mount isn't there

   
   

   Info
   The last two commands add a little extra safety for the case that the directory is unexpectedly not mounted

   
   

3. Mount NFS drive to the mount point

   This command will do a once-off mount.   If it works, you may wish to make it permanent as described in step 54

   Code Block
   language bash
   karatosun@myfirstvm ~$ sudo mount 198.18.255.11:/ifs/data/EUMETSAT_DATA /eumetsatdata

   
   

   Info
   If you receive an error (e.g. timeout), please refer to the troubleshooting section below.

   If step 3 worked, you can now navigate to the /eumetsatdata directory and list all the available data with the ls -lah command

   Code Block
   language bash
   [karatosun@myfirstvm ~]$ cd /eumetsatdata/ [karatosun@myfirstvm eumetsatdata]$ ls -lah total 192K drwxrwxrwx. 7 nobody nobody 124 May 26 13:00 . dr-xr-xr-x. 19 root root 260 Jul 6 13:00 .. drwxrwsr-x. 5 1002 1002 101 Nov 7 2018 eumetcast drwxr-xr-x. 3 nobody nobody 24 Apr 23 2018 mviri drwxr-xr-x. 4 nobody nobody 52 May 28 17:26 seviri

   
   

   Info
   Note that the ownerships and permissions will generally be "nobody"

   
   

4. Making the NFS mount permanent and persistent across reboots (optional)

   Edit /etc/fstab file of the VM with your editor of choice

   Code Block
   language bash
   karatosun@myfirstvm ~$ sudo nano /etc/fstab

   and add the following line

   Code Block
   language bash
   198.18.255.11:/ifs/data/EUMETSAT_DATA /eumetsatdata nfs defaults 0 0

   A complete example of a /etc/fstab can be seen in the block below (do not copy all of this!)

   Code Block
   language bash collapse true
   # /etc/fstab # Created by anaconda on Thu Aug 8 12:37:33 2019 # # Accessible filesystems, by reference, are maintained under '/dev/disk' # See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info # UUID=3ef2b806-efd7-4eef-aaa2 / xfs defaults 0 0 # mount the EUMETSAT NFS server to /eumetsatdata 198.18.255.11:/ifs/data/EUMETSAT_DATA /eumetsatdata nfs defaults 0 0

   To test the persistent configuration, unmount the share, then try to automatically remount it:

   Code Block
   language bash
   karatosun@myfirstvm ~$ sudo umount /eumetsatdata karatosun@myfirstvm ~$ sudo mount -a

   
   

   Info
   If you see an error and the manual mount worked previously, please check for typos!
