Travis CI Build Status

systray-mdstat is a system tray icon indicating the state of local Linux Software (MD) RAID by checking /proc/mdstat periodically:

It works at least on Linux and should work with any status area (aka system tray).

Use Case

The use cases for this utility are probably rather restricted:

  • Desktop or laptop with Linux Software RAID (i.e. at least two permanent disks)

  • Not wanting to have any remote monitoring (e.g. for privacy reasons or due to lacking a permanent internet connection or an appropriate monitoring server).



From a Distribution Package

systray-mdstat is available in most Debian-based distribution releases since about mid-2017:

Of course it's also available in rolling release distributions based on Debian Testing or Unstable:

  • Kali Linux
  • ParrotOS
  • PureOS

It's also available in these non-Debian based distributions:

Packaging status

Building from a Release Tar Ball

Works like most Perl modules or perl-based applications:

$ tar xzf systray-mdstat systray-mdstat-<version>.tar.gz
$ cd systray-mdstat-<version>
$ perl Makefile.PL
$ make
$ make test
$ make install

Building from a Git Checkout

  • Requires Dist::Zilla. Once Dist::Zilla is installed, running dzil authordeps will list the additionally needed Dist::Zilla plugins. After installing them, use dzil build to get a tar ball usable with any CPAN-compatible toolset.

    Afterwards continue as above.

  • Building the Debian package from Git source requires the above plus dh-dist-zilla (which is also available as binary package in more recent releases of Debian and Ubuntu). Running dpkg-checkbuilddeps in the cloned git repository will list all missing build dependencies.
