Searching for issues with my drives I found many people are complaining about the same problems as I have - drives failing randomly - [1-4]. I just ordered WD drives to replace the Seagate ones one by one in the array. I will return the Seagate HDs to the shop. Right now my main concern is to get the data back from the LVM partitions and back it up... The worst thing is the 3 drives failed so unexpectedly and fast I didn't even have a chance to set up a backup solution. Any help would be greatly appreciated.
