For simplicity of setup, we recommend you deploy our designated EWC Community Hub Item onto an existing VM where you wish to access data from. Please refer to the EUMETSAT S3 Mount Flavour for details.
Access to the archive is read-only.
Only a limited subset of EUMETSAT data is available. Please contact the EWC support if the dataset you require is not listed here.
Following describes how to mount EUMETSAT data buckets as FUSE mounts. The possibility to mount the buckets into as filesystem is provided to as convenience. Readers are advised to note that mounting buckets via FUSE will provide significantly worse performance than accessing the data directly from workloads, for example using python. Whenever possible, users are advised to use the buckets directly from the workloads.
Manual mount
Following steps are using ASCAT data as an example. Please modify the commands to mount any other bucket.
Make sure you have latest rclone installed
curl https://rclone.org/install.sh | sudo bash
Create mount directory, i.e. for ascat:
sudo mkdir -p /eumetsatdata/ascat && sudo chown -R $USER:$USER /eumetsatdata/ascat && chmod 755 /eumetsatdata/ascat
Put rclone like listed below config into a config file. For example, into
/etc/eum_bucket_creds (keys without brackets)sudo sh -c "cat >>/etc/eum_bucket_creds <<-EOF [eumetsat-ascat] type = s3 provider = Ceph endpoint = https://s3.waw3-1.cloudferro.com EOF
Now you can already mount the data with command:
sudo rclone --config /etc/eum_bucket_creds mount --allow-other --daemon eumetsat-ascat:ascat.metop-abc.level-1b.native /eumetsatdata/ascat
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.
Link rclone
sudo ln -s /usr/bin/rclone /sbin/mount.rclone
Create systemd service:, for example for ascat:
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: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
Add corresponding line into /etc/fstab:
echo "eumetsat-ascat: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
Mount the folder:
sudo mount /eumetsatdata/ascat
