Disk Utilization

[EndianX]

I finally got my new Debian server up and running. However, I have one last problem. Once the system is finished booting, the hard drive activity light on the case is on solid. I can not figure out why. This is only my second experience using a software raid though. It may have something to do with that.

The ps command shows that the md1_raid5 process is using 10-15% of the processor. But that is probably normal if something is reading/writing to disk.

Does anybody know of a way for me to figure out what is going on? My main concern here is that I am going to quickly burn out my hard drives. This is for a web server that I am using to host for someone else, so it needs to be stable.

Thanks,

Dave

you may have connected the hd light of the case backwards on the motherboard, which would cause it to work opposite how it should

If you just installed, the md driver is building your RAID5 set.

Look at the status of the RAID set:

cat /proc/mdstat

You will likely see something like syncing/building/whatever and a progress meter.

Thank you both very much for the replies. I think you are right. It was building the RAID set. I left it alone for a night and by morning it was working as expected.

I have much to learn about RAID management.
