Windows Server 2008 Hibernation

Unfortunately it seems that W2K8 Server enables hibernation by default, this is very funny because i don’t know how man administrators hibernate a server. But we should think about it and deal with it.

Windows creates a file named hiberfil.sys in the root of the system drive for systems where hibernation is enabled.
The hiberfil.sys file is always the same size as physical RAM.

But you can’t disable hibernation anywhere in the GUI. It must be disabled from the command line using the command:

powercfg.exe /hibernate off

Quote: “….By default, in Windows Server 2008, the Hibernation feature is disabled (power options), yet the hiberfil.sys file is created. The hyberfil.sys file has the size of the servers’ physical memory, which can be many gigabytes. This is pointless because hibernation is not supposed to be used on production servers at all. A complete waste of resources. It may even be included in backups … (haven’t verified this)

At best, the hibernation feature may be used in Windows Server 2008 test/demo environments. Even there it shouldn’t be enabled by default and there shouldn’t be a hyberfil.sys file.”

Installing Windows 2008 from mounted CD/DVD Iso File vers. Rilo

Today i had a problem when i tried to install W2k8, It always got stuck at the phase where it asks for the Win2008 DVD media “Please specify the Operating System Flat File Directory”. It shows me a browse button for the DVD, but whatever directory I select, nothing worked.

The special tip is to enter:

/mount/dvd/
