we had an issue with one of our harddrives. It was dead. All other drives where working properly and are organized in a raid5.
To get access to the dead drive we removed two of them to test if they would work if we changed the slots. Unfortunately we did this while the unit was running, which resulted in two dead drives. After that we wanted to format the first drive that was not running in the first place, removed all other drives but instead of formatting it, we could force enable it over the terminal. After that we could manage to get running the second drive as well.
The raid5 configuration still exists but there is no data available anymore. We have no idea how to recover our files and we would apreciate some help. Thank you very much
