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 freedesktop.org-compliant status area (aka system tray).

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).

• Perl ≥ 5.10
• a bunch of Perl modules:
  • Gtk3
  • Glib::Object::Introspection
  • List::Util (part of Perl's core)
  • Pod::Usage (part of Perl's core)
  • Try::Tiny
  • File::ShareDir to run and File::ShareDir::Install to build and install.

• 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.

• 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.

• smart-notifier (website gone, available in Debian, historic sources also available via snapshot.debian.org: Notifies about S.M.A.R.T. changes your hard disks.

• diskmonitor for KDE: Monitors both, SMART and MD RAID health status.

systray-mdstat adheres to Semantic Versioning, hence all version numbers have the scheme Break.Feature.Bugfix.

• The initial code is very loosely based on the outer framework of the far more complex fdpowermon by Wouter Verhelst under Poul-Henning Kamp's "Beer-ware" license and the tiny mdstat check from Debian's hobbit-plugins package written by Christoph Berg under the MIT license. (Both, Christoph and Wouter stated that the amount of code I copied is too small to make their copyright apply, hence I'm not bound to the licenses they used for their code.)
