Recently I had to upgrade the integration components on a lot of CentOS virtual systems running on a Hyper-V failover cluster. During the upgrade procedure I faced a couple of things, which I'd like you to be aware of. The version on the guest VM is CentOS 6.3, the Hyper-V failover cluster is running under Windows Server 2008 R2 SP1 and consists of 6 nodes.
Below is the output of LVM related commands before starting the upgrade of Linux IC:
Find differences in Public Folder replicas
This is a small piece of code to run it in EMS and to help you finding differences in item number in a public folder structure. The powershell script shows the number of elements in each sub folder for the both of Exchange 2010 servers, which public folder replicas are located on. Below is an example output of the script.
