Solve WSUS error: Unable to open the physical file “C:\Windows\WID\Data\SUSDB.mdf”

If for some reason during the first initialization of the WSUS you get this error because the SUSDB database is missing you can fix it by removing the WSUS Role from the Server Manager Dashboard, and also remove the internal Windows database using this command in Powershell:

uninstall-windowsfeature -name windows-internal-database

After a reboot install the WSUS Role again and you’re done.

Suse Enterprise upgrade from 11 SP4 to 12 SP3 – Error with LVM partitions

If you’re upgrading from Suse Enterprise Server 11 SP4 to 12 SP3 and you get this error:

Some partitions in the system on /dev/XdYZ are mounted by kernel-device name. This is not reliable for the update since kernel-device names are unfortunately not persistent. It is strongly recommended to start the old system and change the mount-by method to any other method for all partitions.
