The Ceph File System, or CephFS, is a POSIX-compliant file system built on top of Ceph’s distributed object store, RADOS.

CephFS for repository

3 Folders were created for each environment:

  1. Production environment - Quota 10TB

    /invenio/invenioprod: client 'fsinvenioprod', Secret in Sesam

  2. Test environment - Quota 1TB

    /invenio/inveniotest: client 'fsinveniotest', Secret in Sesam

  3. Dev environment - Quota 1TB

    /invenio/inveniodev: client 'fsinveniodev', Secret in Sesam

In this guideline we will take a look on how the CEPH FS is configired for the production environment. Which is also the same for Dev and Test environments.


install ceph-common

apt install ceph-common

Create a file

Create a file, and add the secret from sesam.tugraz

nano /etc/ceph/ceph.client.fsinvenioprod

Create a mount path

Create a directory which will be mounted to the CEPH FS.

mkdir /storage

Test mount

This will temporarily mount the directory `/storage to the /invenio/invenioprod

mount -t ceph <ip:port>:/invenio/invenioprod /storage -o name=fsinvenioprod,secretfile=/etc/ceph/ceph.client.fsinvenioprod
Check mounted file systems:
df -h
Filesystem                                                                        Size  Used Avail Use% Mounted on
<ip:port>:/invenio/invenioprod   size     0   size   0% /storage


After this temporarily mounting works, we will unmount it so later we can configure it properly.

umount /storage/

Add Mount configuration

open the /etc/fstab file and edit it as below:

# <file system> <mount point>   <type>  <options>       <dump>  <pass>
<ip:port>:/invenio/invenioprod /storage  ceph _netdev,name=fsinvenioprod,secretfile=/etc/ceph/ceph.client.fsinvenioprod 0 0


mount /storage
