-# BeeGFS Filesystem on Demand (Outdated)
-
-!!! warning
-
-    This documentation page is outdated.
-    Please see the [new BeeGFS page](../data_lifecycle/beegfs.md).
-
-**Prerequisites:** To work with TensorFlow you obviously need a [login](../application/overview.md)
-to the ZIH systems and basic knowledge about Linux, mounting, and batch system Slurm.
-
-**Aim** of this page is to introduce
-users how to start working with the BeeGFS filesystem - a high-performance parallel filesystem.
-
-## Mount Point
-
-Understanding of mounting and the concept of the mount point is important for using filesystems and
-object storage. A mount point is a directory (typically an empty one) in the currently accessible
-filesystem on which an additional filesystem is mounted (i.e., logically attached).  The default
-mount points for a system are the directories in which filesystems will be automatically mounted
-unless told by the user to do otherwise.  All partitions are attached to the system via a mount
-point. The mount point defines the place of a particular data set in the filesystem. Usually, all
-partitions are connected through the root partition. On this partition, which is indicated with the
-slash (/), directories are created.
-
-## BeeGFS Introduction
-
-[BeeGFS](https://www.beegfs.io/content/) is the parallel cluster filesystem.  BeeGFS spreads data
-across multiple servers to aggregate capacity and performance of all servers to provide a highly
-scalable shared network filesystem with striped file contents. This is made possible by the
-separation of metadata and file contents.
-
-BeeGFS is fast, flexible, and easy to manage storage if for your issue
-filesystem plays an important role use BeeGFS. It addresses everyone,
-who needs large and/or fast file storage.
-
-## Create BeeGFS Filesystem
-
-To reserve nodes for creating BeeGFS filesystem you need to create a
-[batch](../jobs_and_resources/slurm.md) job
-
-```Bash
-#!/bin/bash
-#SBATCH -p nvme
-#SBATCH -N 4
-#SBATCH --exclusive
-#SBATCH --time=1-00:00:00
-#SBATCH --beegfs-create=yes
-
-srun sleep 1d  # sleep for one day
-
-## when finished writing, submit with:  sbatch <script_name>
-```
-
-Example output with job id:
-
-```Bash
-Submitted batch job 11047414   #Job id n.1
-```
-
-Check the status of the job with `squeue -u \<username>`.
-
-## Mount BeeGFS Filesystem
-
-You can mount BeeGFS filesystem on the partition power9 (PowerPC architecture) or on the
-partition haswell (x86_64 architecture).
-
-### Mount BeeGFS Filesystem on the Partition `power9`
-
-Job submission can be done with the command (use job id (n.1) from batch job used for creating
-BeeGFS system):
-
-```console
-srun -p power9 --beegfs-mount=yes --beegfs-jobid=11047414 --pty bash                #Job submission on power9 nodes
-```console
-
-Example output:
-
-```console
-srun: job 11054579 queued and waiting for resources         #Job id n.2
-srun: job 11054579 has been allocated resources
-```
-
-### Mount BeeGFS Filesystem on the Haswell Nodes (x86_64)
-
-Job submission can be done with the command (use job id (n.1) from batch
-job used for creating BeeGFS system):
-
-```console
-srun --constrain=DA --beegfs-mount=yes --beegfs-jobid=11047414 --pty bash       #Job submission on the Haswell nodes
-```
-
-Example output:
-
-```console
-srun: job 11054580 queued and waiting for resources          #Job id n.2
-srun: job 11054580 has been allocated resources
-```
-
-## Working with BeeGFS files for both types of nodes
-
-Show contents of the previously created file, for example,
-`beegfs_11054579` (where 11054579 - job id **n.2** of srun job):
-
-```console
-cat .beegfs_11054579
-```
-
-Note: don't forget to go over to your home directory where the file located
-
-Example output:
-
-```Bash
-#!/bin/bash
-
-export BEEGFS_USER_DIR="/mnt/beegfs/<your_id>_<name_of_your_job>/<your_id>"
-export BEEGFS_PROJECT_DIR="/mnt/beegfs/<your_id>_<name_of_your_job>/<name of your project>"
-```
-
-Execute the content of the file:
-
-```console
-source .beegfs_11054579
-```
-
-Show content of user's BeeGFS directory with the command:
-
-```console
-ls -la ${BEEGFS_USER_DIR}
-```
-
-Example output:
-
-```console
-total 0
-drwx--S--- 2 <username> swtest  6 21. Jun 10:54 .
-drwxr-xr-x 4 root        root  36 21. Jun 10:54 ..
-```
-
-Show content of the user's project BeeGFS directory with the command:
-
-```console
-ls -la ${BEEGFS_PROJECT_DIR}
-```
-
-Example output:
-
-```console
-total 0
-drwxrws--T 2 root swtest  6 21. Jun 10:54 .
-drwxr-xr-x 4 root root   36 21. Jun 10:54 ..
-```
-
-!!! note
-
-    If you want to mount the BeeGFS filesystem on an x86 instead of an ML (power) node, you can
-    either choose the partition "interactive" or the partition `haswell64`, but for the partition
-    `haswell64` you have to add the parameter `--exclude=taurusi[4001-4104,5001-5612]` to your job.
-    This is necessary because the BeeGFS client is only installed on the 6000 island.
