mkdir build && cd build
cmake .. -DCMAKE_INSTALL_PREFIX=$(kf5-config --prefix) \
       -DCMAKE_BUILD_TYPE=Release \
       -DKDE_INSTALL_USE_QT_SYS_PATHS=ON

make

• Display S.M.A.R.T. attributes for harddrives supporting it
• Start and monitor progress of S.M.A.R.T. Short and Extended self test

• Display properties for MDRaid arrays
• Start and monitor progress of data scrubbing on MDRaid arrays

• Display basic health status for storage units
• Can be used on the desktop, on a panel or as a systray icon (see systray settings to activate)

The easiest way to test the monitoring is by using a "fake" raid array. The idea is to create a small array using loop devices :

# you may need to load the 'loop' module
modprobe loop

# then create two files for use as block devices
dd if=/dev/zero of=/root/raid/r0 bs=1M count=20
dd if=/dev/zero of=/root/raid/r1 bs=1M count=20

# attach the files to loop devices
losetup /dev/loop0 /root/raid/r0
losetup /dev/loop1 /root/raid/r1

# to check everything went ok
losetup -a

# now create a new raid array
mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/loop0 /dev/loop1

# check the raid status
cat /proc/mdstat

Then you can fail and restore raid devices at will :

# fail the loop0 device
mdadm --manage /dev/md0 -f /dev/loop0

# restore the raid by removing and readding the device
mdadm --manage /dev/md0 -r /dev/loop0
mdadm --manage /dev/md0 -a /dev/loop0
