I’ve recently noticed it on some machines that are serving a web server and a MySQL database.
This happens after veeam is done backing up and has to merge the snapshot file. During that time, that could go from 30 seconds to 10 minutes, some of my machines stop responding to ping, giving service and even responding on direct console connection.
My datastores are nfs3, could this have anything to do?
I also got the impression that machines with greater count of disks seem more impacted or maybe it’s just machines with higher IO.
Any clue on what could be happening? Any ideas on how to mitigate this effect?
***EDIT: Initially stated VMFS3 instead of NFS3
