 EUMETSAT data archive rests on the public NFS share and in order to access it, you need to mount the NFS drive to the Virtual Machine(s) that you want to access the data from.

Setting up your instance

For fast data access, you will need to provision your instance on the EUMETSAT cloud.

In order to mount the NFS drive, first, you need to create the Virtual Machine instances in the Morpheus UI. Currently, data access works both operating systems provided by European Weather Cloud (CentOS and Ubuntu) and requires no additional configuration. You can follow the Provision a new instance - web Knowledge Base Article to get started with the provisioning.

Mounting NFS Share

After logging in to the virtual machine that you want to access the EUMETAT data, all you need is to mount the NFS drive rests on 198.18.255.11 to the directory that you want it mounted. In order to do that, please follow the below steps;

1. Display all exported file systems from an NFS server (Optional)

You can see all exported file systems from the EUMETSAT NFS server without mounting it to the directory. In order to do that, just run showmount command like in the example below;

karatosun@myfirstvm ~$ showmount -e 198.18.255.11
Export list for 198.18.255.11:
/ifs/data/Isilon_Support 
/ifs/data/PROD-MORPHEUS-BACKUP-SHARE 
/ifs/data/EUMETCAST 
/ifs/data/EUMETSAT_DATA 
.
.
.

this command will return all the possible mount points.

2. Create the directory

Now, we need to create a new directory. This directory will be the mount point of the NFS drive. This step requires sudo permissions.

karatosun@myfirstvm ~$ sudo mkdir /eumetsatdata

 3. Mount NFS drive to the mount point

Now all we need to do is to mount the NFS share to the directory that we created in the previous step. This step also requires sudo permissions.

karatosun@myfirstvm ~$ sudo mount 198.18.255.11:/ifs/data/EUMETSAT_DATA /eumetsatdata

after this step, you can navigate the /eumetsatdata directory and list all the available data with the ls -lah command



4. Permanent NFS mounting (optional)
We have to re-mount the NFS share after every reboot. In order to make it permanent, we need to edit /etc/fstab file of the instance with nano (with sudo permissions)


karatosun@myfirstvm ~$ sudo nano /etc/fstab


and add the following line;


198.18.255.11:/ifs/data/EUMETSAT_DATA /eumetsatdata nfs defaults 0 0


An example configuration file can be seen below;


#
# /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

198.18.255.11:/ifs/data/EUMETSAT_DATA /eumetsatdata nfs defaults 0 0


Limitations
1) Access to the archive is read-only.
2) Not all EUMETSAT data available.
