[MooseFS-Users] How do I verify that the MooseFS cluster is online and working inside a systemd.service

[Markus K. <mar...@tu...>]

Hi!

In the FAQ section there are 3 methods mentioned how to verify the connection to the mfsmaster.
I wonder whats the best best way to test (inside a systemd.service) if I can read and write files also in case my dedicated network for communication with chunkservers is not working?

My goal would be preventing a srvice (slurmd) from starting in that case.

For preventing slurmd.service from starting in case the MooseFS file system is not mounted I have something like that in mind:
# /etc/systemd/system/slurmd.service.d/override.conf
[Unit]
After=remote-fs.target
AssertPathIsMountPoint=/mnt/mfs


The question is how can I make sure that the communication is working and I can read and write files?



Thank you,
Markus Köberl
