Excessive High Disk errors in Windows 2008 Small Business Server
Posted on 2012-08-24
I inherited an SBS 2008 server recently. It was running really slow and bogged way down during reboots and running backups - to the point where it was unusable.
The previous manager had installed Symantec Endpoint Protection and the System Manager on this server and not made exceptions for SQL server files and other things. I removed all of this software because the license expired. The server is running a lot better now, but there are regular spikes in disk activity that set off the monitoring software.
The server is being used by one guy with two email addresses. Most of the time, he's not even in the office and using the network. Just accessing his email.
I loaded up Resource Monitor and found that the processes using the most disk activity are:
C:\Windows\SoftwareDistribution\DataStore\DataStore.edb -- Read 140,354,555 B/Min
C:\WSUS\SUSDB\UpdateServicesDBFiles\SUSDB_log.ldf -- Read 54,234,553 B/Min
There are big sustained reads and writes. The server's memory is pegged at 93% usage (8GB RAM) with the two biggest users being SQL Server. 1.5GB each.
I'm not sure what's going on here, but I need to get the usage down. I don't see any disk errors in the Event Log.
Thanks for the help.
