comment replacing 3 drives out of 8 in a server
@Pico the document I linked to provides the relevant information on the various RAID levels an their strengths/weaknesses. Which you choose to use is a business decision. I don't know what a blinking light on a Dell R510 (drive) means but I do know that now you have replaced 3 drives your RAID 5 is dead and will need to be recreated and the data recovered from a backup.

I don't see a system administration problem here. Check the php exec() manual. there are parameters that you're not using that look useful.
