skolima's questions

I'm following the most basic example on MSDN and I'm failing to get it to work. I've got my configuration defined as follows:

Configuration MyWebConfig
{
   Param($ComputerName)

   Node $ComputerName {
      WindowsFeature MyRoleExample
      {
          Ensure = "Present"
          Name = "Web-Server"  
      }
    }
}

I'm trying to generate MOF with C:\Scripts> .\IisWithCompressionConfig.ps1 -ComputerName "localhost" -Outputpath C:\Scripts\localhost (and couple other command line variants). I'm not getting any file output and no errors are reported (exit status code is also 0). I've tried a version without the $ComputerName variable (and instead "localhost" hardcoded), still nothing. Yes, I'm running this in an elevated prompt.

I've made sure that I'm running PowerShell 4.0:

C:\Scripts> $PSVersionTable

Any ideas what am I missing?

Windows Resource Monitor is a nice (and built-in) tool providing a fast overview of resource utilization. On a server with Hyper-V installed, it correctly shows the CPU and disk activity generated by the virtual machines, but somehow they are excluded from the memory load statistics. Is there a way to include them?

I have assembled a new raid array to replace an old one. However, this new array got assigned an automatic name of /dev/md127 and I want to rename it to /dev/md3, so that I don't have to change various other settings. How do I rename an mdadm raid array?

When my Windows Server 2008 R2 machine is performing any large disk operations (copying 10GB files from one drive to another, copying similar file over network, merging HyperV snapshots, compressing large files), performance of the whole machine slows down terribly, everything becomes unresponsive. This is noticeable in any situation when the disk access is large enough not to fit in the cache.

Are there any settings available for tuning this behaviour? I can accept slower file transfer if this would give me more responsiveness.

System details: Dell Optiflex 960, Core 2 Quad Q9650, 8GB RAM, 2 SATA drives - 320GB (ST3320418AS) and 1TB (ST31000528AS), NCQ active on both, Intel 82564LM-3 Gigabit Ethernet, ATI HD 3450 graphics, Intel ICH10 bridge. We have multiple machines like this, every one is exhibiting the same behaviour. I though this was overkill for a workstation, apparently I was mistaken.

Update: I guess I shouldn't have mentioned the HyperV at all. The above configuration is a standard workstation setup at the company I work for, this is not a server of any kind. I have at most 3 virtual machines working, and usually I'm the only person accessing them. Never the less, the slowdown occurs even when no VMs are running. On a Linux machine I'd simply ionice the copy process and I could forget about it, is there any way to manage IO priorities on Windows?

(This is a follow-up to "What is the partition id / filesystem type for UDF?")

I know two ways to format a hard drive as UDF:

• Windows Vista or later: "format x: /fs:UDF" (don't use /q ! )
• Linux: "mkudffs --media-type=hd --blocksize=512 /dev/sdx"

The problem is that the 'other' OS does not recognize the disk as formatted at all: it simply refuses to mount it, no matter what commands I try.

How can I format a hard drive as UDF so that both Windows and Linux will be able to use it?

EDIT: updated the commands, now the result should work in either OS.

This is probably trivial to check using cfdisk on a UDF-formatted CD/DVD/Blu-Ray, but I have neither of them at hand.

I have created an UDF formatted partition on a USB hard drive to share data between Linux and Windows computers (FAT doesn't handle 4GB files, NTFS access rights support is not stable under Linux). I have only one problem now - Windows refuses to mount the partition as the file system type id is set to '83' ('Linux'). I have looked quite extensively and can not find what number should I put there?
