From the extremely limited information you've given, it's hard to diagnose
the problem.
In future, please include the output of dmesg and the output of relevant
commands in problem reports. This answers questions such as: how many
disks are in this server? Are they part of an array?
...
Definitely see your problem...most of your dmesg is missing!
(when people ask for a dmesg, it's the entire dmesg, not the chunk YOU
think is interesting)
However, seeing that you have a HW RAID card and an array on it, I'm pretty
sure you WILL be seeing disk activity as the HW RAID card does its things on
the disks with nothing going on at the OS or application level.
Is that ALL you are seeing? Can't say. But disk activity on a HW RAID card
is just normal. Disk activity from processes using very little processor is
also not unexpected, but I'd expect the disk lights on the HW RAID attached
drives to periodically flicker even if sitting at the boot> prompt.
And...if you are running firefox or any other browser, you have a LOT of
packages loaded on your system. Good luck trying to quiet all of them.
(better idea: don't fight it).
