I'm running linux on a Compaq ProLiant DL360 G2 with two 72 Gb hard disks in RAID-1 configuration. When I shut down the system, after linux is completely halted, both hard disks show intense activity indefinitely (for more than 24 hours). I have to switch off and on the server if I want to start it up again. The server and the hard disks seem to work fine.
Why do the hard drives show this behaviour? Is there any failure in my disks? How can I diagnose it?
Thank you very much in advance for your help.
