Fragmented Files on Windows 2003 SBS
Posted on 2013-06-13
I have one client with a Dell PowerEdge 840 (~5 years old) with a Dell SAS 5/iR Controller and 2 SAS Drives in RAID 1 mode. The drive has been partitioned into a 25GB System and the remaining 206GB for Data.
About a year ago, the users noticed things we "running slow", and lately they notice it more and more. What seems to be happening is the files on both the System and Data drives become fragmented -- but only about 15% of them. The LED for drive activity is usually on solid.
The built-in Disk Defragmenter won't defrag most of the files so I'm usinig the free Auslogics tool. Once it defrags, the server runs fine. So, I created a Scheduled Task to run it on Saturdays -- which it did this previous weekend. But the client called me this morning to say it was slow again, and the LED lights on solid and files are fragmented again. BTW, Exchange in this SBS edition is only used for downloading e-mail into the Mailboxes from the user's Desktops via POP. It's not being used as a full SMTP server.
I booted into the RAID configuration and both drives are reporting healthy. The Write Cache settings for the Disks are grayed out but "Optimized for performance" is selected. I don't have the Dell Windows utility installed to check the settings (can't figure out which one to download and install). There are no Errors or Warnings logged in System Events.
Any ideas as to what might be causing this? I've worked on many servers before and have never seen this kind of activity before without some type of failure.
