CentOS - Apr 2021 - Problem with RequiresMountsFor defined in a systemd service

Hi all,

 I have setup a systemd service that needs to mount a NFS share before starts.
To accomplish this I have defined:

RequiresMountsFor=/data/sysos

As a dependency in [Unit] section but it doesn?t work. NFS share is defined in
fstab with ?defaults,noauto? options also ..

What am I doing wrong? How can I debug this?

Best regards,
C. L. Martinez

Maybe set up the NFS mount with autofs instead?

Having 'noauto' in the fstab options means that it can only be mounted
explicitly, and not through automatic mounting (which is what systemd
would do if you set it up as an automount).

You need to either fix it so it gets mounted on demand, or use some
other method to start it.
