I have been seeing some really odd issues lately on a couple of our Hyper-V hosts. I initially had chocked the issues up to slow storage access speeds caused by a possibly defunct storage controller on one particular server. However, recently the issues got worse. I was getting random errors that were preventing me from deleting snapshots. After a quick google search the answer came back as “turn off your server’s anti-virus”. Sure enough, turning the anti-virus software off cleared up the issues I was having.
This is just one more thing that persuades me that Antivirus software tends to cause more problems than it prevents. I get the argument for it. Especially on endpoints where PEBKAC issues run rampant… But it causes a lot of headaches…
