I noticed that the D drive on an exchange server was very defragmented (using the inbuilt standard Windows defragmentation tool). When I pressed analyse it showed a big block of red.
I thought I better check before running in case the defrag could cause some damage to exchange and reading around I am not sure I should actually risk running it.
I've determined there are three types of defrag related to Exchange.
Standard normal defrag- the tool we all know and love.
Online defrag - something that exchange does automatically daily I believe.
Offline defrag - run with caution and only when necessary. Requires downtime and risk associated.
I just want to run a simple defrag but even reading about this I'm have read that I should dismount the stores first (Something I'm not 100% sure how to do) and also I should just not bother risk running in on the drive where the exchange data is stored (which is the drive I want to defrag).
Can I get some expert opinions?
