1. Make sure you have latest rclone installed

   Code Block
   curl https://rclone.org/install.sh | sudo bash

   
   

2. Create mount directory, i.e. for ascat:

   Code Block
   sudo mkdir -p /eumetsatdata/ascat && sudo chown -R $USER:$USER /eumetsatdata/ascat && chmod 755 /eumetsatdata/ascat

   
   

3. Put rclone like listed below config into a config file. For example, into /etc/eum_bucket_creds 

   Code Block
   sudo sh -c "cat >>/etc/eum_bucket_creds <<-EOF [eumetsat-ascat] type = s3 provider = Ceph env_auth = false access_key_id={{ aws_access_key_id }} secret_access_key={{ aws_secret_access_key }} endpoint = https://s3.waw3-1.cloudferro.com EOF

   
   

4. Now you can already mount the data with command:

   Code Block
   sudo rclone --config /etc/eum_bucket_creds mount --allow_other eumetsat-ascat:847632567fbf45408555318627075a26:ascat.metop-abc.level-1b.native /eumetsatdata/ascat

   Please note the special naming convention rclone_config_name:ceph_tenancy_id:bucket_name. This is due to the CEPH multi-tenancy setup. If you are mounting your own bucket, you can drop the tenancy id and use the standard bucket naming style: rclone_config_name:bucket_name.

   
   

Setting up a service

To have mount points available all the time and after reboots, one need to set up the service and add mount points into fstab.

1. Link rclone

   Code Block
   sudo ln -s /usr/bin/rclone /sbin/mount.rclone

   
   

2. Create systemd service:, for example for ascat:

   Code Block

   sudo sh -c "cat >>/etc/systemd/system/eum-data-ascat.service" <<-EOF [Unit] Description=Mount EUMETSAT data bucket ascat After=network-online.target [Mount] Type=rclone What=eumetsat-ascat:847632567fbf45408555318627075a26:ascat.metop-abc.level-1b.native Where=/eumetsatdata/ascat Options=ro,allow_other,args2env,vfs-cache-mode=writes,config=/etc/eum_bucket_creds,cache-dir=/var/rclone,vfs-cache-max-size=512Mi,vfs-cache-poll-interval=30m' EOF

   
   

3. Add corresponding line into /etc/fstab:

   Code Block
   echo "eumetsat-ascat:847632567fbf45408555318627075a26:ascat.metop-abc.level-1b.native /eumetsatdata/ascat rclone ro,noauto,nofail,x-systemd.automount,args2env,allow_other,vfs_cache_mode=writes,config=/etc/eum_bucket_creds,cache_dir=/var/cache/rclone,vfs-cache-max-size=512Mi,vfs-cache-poll-interval=30m 0 0" | sudo tee -a /etc/fstab

   
   

4. Mount the folder:

   Code Block
   sudo mount /eumetsatdata/ascat
