Hi,
At the moment my HP ProLiant is running OMV 3.0.89.
Three HDDs are bundled to a RAID5.
Now I wanted to add the 4th HDD with the same size of 2TB.
I formatted the new HDD with ext4 - like the RAID5 HDDs.
Afterwards I mounted the new HDD.
But, there is a problem with expanding the RAID5. The RAID control panel does not show any new HDD after pressing the button "expanding".
What am I doing wrong ?
