Yesterday I got a problem while migrating a fileserver cluster from Windows 2003 to Windows 2008 R2.

We wanted to migrate a big fileserver cluster with several volumes by mirroring the SAN LUNs, break the mirrors and mount them to the new Windows 2008 R2 fileserver.

After mounting the partitions to the new cluster we set up a new virtual fileserver and created some shares. With one partition/share we run in the following error:

The shared ressource is not available.

After some investigation we figured out that the SYSTEM group doesn’t had permissions on the partition at root level so the cluster service running with local system account can’t initialize the share.

After adding SYSTEM at root level with full access sharing of this partition was possible:

A couple of days ago I had a problem with an Exchange Server running out of space. I controlled database and logfile partitions and could not detect anything suspicious.

After some researches I figured out Volume Shadow Copies require much space because a backup job didn’t finish succesful and leave the VSS data on disk.

In my case vssadmin deleteshadows didn’t work, too. After some investigation I found a way to delete the Shadow Copies with the command line for WMI – WMIC

In summary you have to do the following

  • Start an elevated commandline window
  • Type in wmic and press enter
  • wmic:root\cli is shown
  • Type in shadowcopy which will list the current shadow copies
  • Type in shadowcopy delete and confirm to delete the copies one after the other
  • To leave the WMI commandline type exit

Cheers,
