Trondh's questions

I have this weird error on my Kubernetes test cluster. I'm running Kubernetes 1.7.0 and docker Docker version 1.12.6, build 78d1802

I have a separate volume mounted as /dockerdata and symlinked /var/lib/docker into this volume. I have ample space available on both my system volume and the dockerdata volume (more than 50% free). I still get ImagePullBackOff errors from kubernetes, the detailed error is:

Failed to pull image "<redacted>": rpc error: code = 2 desc = failed to register layer: ApplyLayer exit status 1 stdout: stderr: open /usr/share/man/es/man1/fakeroot-sysv.1.gz: no space left on device.

If I manually clean up by removing stale images I can get around this, but as far as I can see I shouldn't have to - since none of my volumes are nearing full capacity (which I guess is also why the Kubernetes GC doesn't kick in).

I'm guessing there's something I don't understand about how Docker works in relation to local disks but I'm stumped. Any pointers appreciated.

Here's some more info: symlink info:

I have a vm running apache2, and setup a simple public load balancer to hit it. This works fine.

However, I'm trying to use this in conjunction with user-defined routes. The reason for this is that I need to know which public ip address my VM uses for accessing the internet, as this vm needs to access another system on another network (this is a very simplified version of our real-life thing, so bear with me).

I have set up an "nva vm" running ubuntu which performs nat translation, and using UDRs I have set my "apache vms" subnet to route thru the nat vm (using destination 0.0.0.0/0 as the destination). When I activate this setup, my apache vm can no longer be accessed using the load balancer.

I can't find any information regarding "special considerations" for using LBs and custom routes, is this not a supported setup?

I tried deleting a subnet from my Azure Vnet, but that failed. THen I figured out how to just change the mask length of the subnet, so I don't need to delete it anymore. Problem is, the entire network is now marked as "failed" and I can't do anything to it because of that state.

So, how can I "reset" it to a successful state without deleting it?

On the current version of WMF5, I try and invoke a DSC resource using Invoke-DSCResource like so:

$destinationPath="$env:SystemDrive\DirectAccess.txt"
$fileContents="This file is create by Invoke-DscResource"
$result = Invoke-DscResource -Name File -Method Test -Property @{
DestinationPath=$destinationPath
Contents=$fileContents } -Verbose
$result | fl * 

However, I'm asked for a module name for the "File" resource.

Doing Get-DscResource File lists the dsc resource, but the "module" property is empty. How can I figure out which module to pass Invoke-DscResource? Where (in what module) does the "File" resource really live?

We have some mail-enabled public folders which are members of a distribution list so that they receive mail from external senders. From time to time (not every time) I'm seeing this error for mail that should land in the PF:

Anyone seen anything similar before? I'm at a loss here. Considering moving to a new PF database. Any pointers appreciated!

I have VM's running in Azure, and I see this error quite frequently: The VMs can be reached using either fqdn or public ip. When ssh-ing to the fqdn I'm able to log in (part of the fqdn obfuscated deliberately): However, using the same VM's public ip I'm getting access denied:

I guess it's related to the suffix added after the user account, but how can I make sure this doesn't happen? I've also seen the same error when the VM has gotten a new ip address after having been shutdown for a period of time (basically locking me out of the vm). I'm generally running Ubuntu 14.04 vms if that's relevant.

When I look at the host keys, they are the same for the two connections, although I have to "approve" them separately to add both instances to known_hosts. I'm using putty on windows as my ssh client.

as part of a migration scenario we need to be able to receive mails on our local Exchange 2010 SP1 server as well as forward all incoming mail to an external host (even if mail is succesfully delivered on local server). Is there a way to do this in Exchange 2010 or do I need to set up another SMTP server in front which can send incoming emails to two different hosts?

I've been trying to get my mind around this one for the last hour, if anyone has a pointer to who it's done I would appreciate it:

Background: Our VMWare ESXi guests use scsi-based virtual disks all over. This lets us expand our virtual disks in real-time, a feature we use a LET, both on the OS drive (requires windows 2008 and later) and any data drives.

Now, evaluating Hyper-V I need to emulate this. The doc states that a hyper-v guest can only use IDE as boot device, and only SCSI-disk have the option to expand on the fly. So, I want to install Windows 2008R2 with two drives: Disk 0: IDE: boot files only Disk 1: SCSi: Windows (regular C drive)

If possible, I want to avoid giving the IDE-disk any drive letter at all, so that for a regular server admin it will look just like a regular (vmware) guest, with the windows folder on C: and all that.

Have anyone done this? Before I started researching it I thought this would be the way everyone did it, but I can't find much good info out there...

I've just been tasket with recovering a failed Exchange 2007 CCR install for a customer.

It seems here that the operator has deleted the Cluster name and then added it again (effectively deleting the original cluster config from AD. So, my question is: Does anybody know how I can update ad with a "working" config to get this running again?

A customer of mine is migrating some serveres to a provider, which will cause (temporarily) clients and servers to be in separate, untrusted AD domains. The application in question is a SQL Backend / Access Client application which uses trusted connections between the Access app on the client and the sql server.

My question is: Is there any way to get some kind of single-sign on to work here, so that users avoid having to enter usernames/passwords when using the app?

This might be basic, but hopefully someone can help me:

We have a well-working SCOM 2007 R2 implementation monitoring our Microsoft infrastructure. Now, on one of these servers there's an event (logged to the eventlog) that I need to be alerted on.

I have created a group and put this one windows server in it. Then, I created a monitor with simple event detection, entered the event id and used the group name as "monitor target". This doesnt work - the monitor doesn't show up in health explorer at all.

However, If I create the monitor with "Windows computers" as target it works, but that means I'll have to disable the monitor, and then enable it for the group, which is cumbersome and slightly illogical to me.

Is this by design, or am I doing something wrong?

We are hosting several mail solution, among them a Hosted Exchange 2007 platform. Some of our customers would like to migrate from one of our other platforms (which stores emails in eml files), and we'd like to be able to migrate mail (which means tons of eml files) for a given user into an exchange mailbox. Since this is large-volume it would be incredible cumbersome to do this via Outlook per user.

Does anyone know anything about any software or api that would allow us to (bulk) import emls into an exchange mailbox?

We have some old sharepoint data (from a WSS 3.0 SP1 or SP2 install), that I need to restore. Problem is: This is a time management site, and one of the fields automatically pics up the user name of the user that enters data, and this is used to keep track of who worked when.

Now, when I import this into my temporary sharepoint 3.0 server, these fields are blanked, and the creator of the element is replaced by my admin user (the account that ran the import job).

So, to the question: Is there any way at all to grab hold of these data before the sharepoint import job "destroys" them? I'm using stsadm -o import.

I don't care if I have to pick the database itself apart manually, I just need to know if it's possible to get hold of these fields with data intact from my export files...

(Backup you say? It was deleted loong ago. This sharepoint export is all we have...)

Im trying to construct a powershell script that uses some XML. I have a XML document where I try to add some values with email addresses. The finished xml document should have this format: (I'm only showing the relevant part of the xml here)

<emailAddresses> 
    <value>[email protected]</value> 
    <value>[email protected]</value> 
    <value>[email protected]</value> 
</emailAddresses>

SO, in powershell I try to do this as a test, which fails:

$newNumber = [xml] '<value>555-1215</value>'
$newNode = $Request2.ImportNode($newNumber.value, $true)
$emailnode.AppendChild($newNode)

After some reading, I have figured out that if I do this, it suceeds:

$newNumber = [xml] '<value name="flubber">555-1215</value>'
$newNode = $Request2.ImportNode($newNumber.value, $true)
$emailnode.AppendChild($newNode)

So, I am stuck. I'm starting to wonder if I should use another function instead of importnode when I have several keys with the same name but different values.

As you guys probably have figured out by now, i'm not an expert in xml. ANy help appreciated!

We had a severe crash on one node of our 2-node Windows 2008 / Exchange 2007 CCR Cluster the other day, and i tried to rebuild the node from scratch.

I'm using this as a rough outline:

http://edmckinzie.spaces.live.com/Blog/cns!687C72A5909E4230!508.entry?sa=641979772

The problem: Our cluster was originally setup with only one NIC per host, as this is supposedly supported in Win2008 (no dedicated heartbeat NIC). When I add my freshly installed node to the cluster, it shows up with two cluster networks, "Cluster Network 1" & 2. The existing node's NIC has been placed in one cluster network and my fresh installed has ended up in the other.

I can't find anywhere in the GUI to choose which cluster network each physical NIC should be part of, but i KNOW I have done this before. Time is of the essence on this one, so I was hoping someone in here had the answer on the top of their head...

Thanks for any pointers.
