Description hp4everything 2014-03-03 11:22:09 UTC

I'm running minidlna and httpd on a RaspPI with archlinuxarm. Disk space for both services is located on a NAS drive and automounted. Both service files therefore contain the following dependencies:

---------------------------------------------
Requires=network.target autofs.service remote-fs.target nss-lookup.target
After=network.target autofs.service remote-fs.target nss-lookup.target
---------------------------------------------

Both services fail to start (see syslog messages below, which indicate that the NAS-directories are not yet mounted or mountable)

- httpd exits because its root-directory is not yet available
- minidlna keeps running in an invalid state, because it didn't find its directories during startup

After that both services can be started manually without problems with systemctl start ...

Comment 1 Zbigniew Jedrzejewski-Szmek 2014-03-03 13:18:26 UTC

Can you show the output of 'systemctl cat minidlna', 'systemctl cat httpd' (or whatever the units are called)? And the output of systemctl list-dependencies --all for them?

Comment 2 hp4everything 2014-03-03 14:13:34 UTC

Created attachment 95026 [details]
requested information, unpack with tar -xvzf data.tgz

information as you requested in 4 file

minidlna.dependencies
httpd.dependencies
minidlna.cat
httpd.cat

the .cat files are generated by the cat-command, my systemctl doesn't know any cat-option for the systemctl-command.

The service files for httpd and minidlna are the files from the original archlinux-distribution with the exception, that I've added the Requires- and After-Options.

Can you please attach the files as-is without making it so complicated to view them?

Closing due to lack of response.
