HDD Read LED always on

[LNBewildered]

Hi - new to all this but not to IT....
Built a FreeNAS box (v9.3) on an old Asus M2A-VM mb with 2 new WD RED 3Gb drives.
Install went (relatively) OK but the HD activity light is always on - activates as soon as the drives mount.
Setup works great but I have been reading the various posts around this and moved the logging files to a USB etc but nothing seems to make a difference.

Are the drives truly active or is this common in this sort of NAS config?

Apologies for such a basic question...

Does it flash or just always on. Usually a red light means something is broken. Activity lights are usually blue or white. What version of freenas and what hardware do you have.

Always on - its the system HDD read indicator. Its wired correctly as works fine on Windows and other Linux OS (eg flash on read/write).
Running on Asus M2A-VM mother board, AMD Athlon X2 6000+, 4Gb RAM. Not the ideal config but an older test rig.

cheers

Ehh you have half the required amount of ram. This isn't causing your silly red light issue but your system isn't even supported so you should fix that first.

Many thanks - RAM isn't high enough I agree. Built as a test and all seems ok except the activity lights. If I get that resolved then upgrade on the cards - just worried it is going to damage the drives.

One thing to note is that you will almost always have disk access occurring. Either by logs getting written to disk, scrubs or reporting data getting written to disk. It's not something to worry about unless it is extreme and affects performance. If this happens there is something wrong with your pool and you should figure out that problem first.

Many thanks. Appreciate the feedback - FreeNAS impressive product with many moving parts so worth the time to get to know it.
