Re: NTP issues on 5.5


Re: Yosemite Guest OS on Sierra Host OS - possible?

0

Hi,

 

It is more likely something to do with the CPU and while it is not completely irrelevant, but this is something that a VM can shield off.

 

If your host has a newer CPU as the guest OS supports then you can actually show the guest OS an older model of the processor.

This is called CPU masking, by masking off the newer features that your guest OS doesn't support, it does not end up getting confused.

 

Not too long ago there was an issue like that where Oracle refused to run on newer macbooks and it was fixed by CPU masking.

Eg, Re: Fusion and Oracle 12c issue

 

I would expect that Fusion does the CPU masking on your behalf, not that you would have to edit it by hand and if not you can always report it here and we try to help out.

VM Workstation 12.5.2 issues (vmware-vmx - high cpu utilization & excessive vmdk fragmentation)

0
0

Recently upgraded to 12.5.2, I have several older (11.x) VMs that I've migrated over from the older version of VMware WS. Newly created VMs are running into the issue described in the title of this thread (I have some newly created VMs that the vmware-vmx.exe runs at 50% of cpu).

 

Anyone have any suggestions?

Re: Repair / Recover VMFS Volume

sshfs -o ro root@esxi1:/ /esxi

sshfs root@esxi2:/vmfs/volumes/datastoreRecoveryOUT /vmfs-out

 

I presume that this above is when you want to 'chroot' to enviroment?

 

I was trying to ddrescue file from datastore to another datastore and it failed. By the way when I used vmfs-fuse to mount datastore which was the outfile (destination path) it was mountend only RO and I i couldn't save the file into it.

 

I made
1.  vmfs-fuse /dev/sda1 (broken driver with important vmdk file) /mnt/in

2. vmfs-fuse /dev/sdb1 (destination datastore) /mnt/out

 

after that ddrescue /mnt/in/file.vmdk /mnt/out/file.vmdk


And received error I/O


So now trying to recover but with -d and -r1 as raw file if it works I will be able to mount the raw file in loop to pull the vmdk file.

So Basically  pulling file to file doesn't work all the time.


Update:


After the ddrescue finished It just cloned the disk to file with the same error. So when I tried to fsck.vmfs datastore.raw file I get lots

Orphaned VMDK Script is Reporting Inappropriate Data

0
0

Hi,

 

Can you please help with the below:

1. This script is reporting the VMDKs of Powered Off VMs too as Orphaned.

2. We have a mix of Thick and Thin provisioned disks in our environment, so can we report only used size of the VMDK instead of Provisioned space. Currently it is fetching Provisioned size (wherever there are thick disks), which doesn't give real number for the total orphaned space that can be reclaimed, if we can fetch used size then the real orphaned space would make more sense.

3. It's reporting the disks of VM templates as Orphaned, how do we filter this out completely.

4. Also, what changes to the code can we make to filter out datastores with local (case insensitive) in name, these are very rare in our environment but still want to filter out before hand).

 

Appreciate your inputs. Thanks. 

 

Current Version of the Script (main code):

 

report = @()

 

Get-View -ViewType Datastore -Property Name,Browser,Host | %{

    $ds = $_

    $dsBrowser = Get-View $ds.browser

    $rootPath = "[" + $ds.Name + "]"

    $searchSpec = New-Object VMware.Vim.HostDatastoreBrowserSearchSpec -property @{

        matchPattern="*.vmdk"

        details= New-Object VMware.Vim.FileQueryFlags -property @{

            filesize=$true

            modification=$true

        }

    }

 

    $searchResult = try {

                          $dsBrowser.SearchDatastoreSubFolders($rootPath, $searchSpec)

                        }

                    Catch {

                      $Error1 = $Error[0].Exception.Message

                      LogWrite "On $vCenter - Error: $Error1

                      }

     

    foreach ($folder in $searchResult) {

          if ($fileResult.Path -match "-flat.vmdk"-and ($fileResult.Modification -lt $DaysOld)) {

        if (-not ($arrUsedDisks -contains ($folder.FolderPath + $fileResult.Path))){

        $row = "" | Select DataStore, Path, ProbablyOrphanedFile, SizeGB, LastModifiedOn, Host, SizeBytes

This really is an amazing story! I have been having catastrophic problems with my MBP since Fusion 7 and noone could cure it. Sluggishness, constant spinning balls, constant crashes, i had completely given up on ever getting windows 7 to work in anything above Fusion 4.

 

8-10 hours with Fusion's tech support revealed nothing whatsoever, however many times they pretended to turn off hardware acceleration.

 

Then this coolscan problem.

 

Then I concluded over 4-5 hours on the phone with applecare that it was a hardware problem, probably motherboard related, and put in an insurance claim.

 

But the bloke at applecare did try to say that with this sort of conclusion, there is a one in 1000 chance of a Genius Bar diagnosis off 'something else'

 

Blow me down! The nice girl at thhe apple store almost immediately diagnosed a DU problem and did a COMMAND-R start to the recoveery partition. There, DU ran, finding all sorts of lost-cluster-like problems.

 

HEY PRESTO, suddenly the MBP runs like brand new, XP and 7 run perfectly, the scanner is immediately identified as an LS40 (or an IOUSB device, there is no difference), XP immediately sees its new USB connected device and installs drivers.


What is even more baffling is that throughout this process I have upgraded OSX numerous times and run DISK WARRIOR numerous times with out these cataclysmic file system problems either manifesting themselves or even being found!

the esxi hosts ARE syncing to a time server located on an ESXI host. 

 

The NTP server is reachable and all ports open.

 

the time sync does work but it seems like the time falls behind by a minute or 2.

Re: Completing vSphere 6 foundation exam(2V0-620) will provide any VCA certification?

There is no connection whatsoever between the vSphere Foundations exam and any of the VCA certifications.

 

Foundations is a core exam for all the VCP6/VCP7 certifications.

 

I don't personally think VCA certifications have value, so would suggest you proceed with the Foundations exam followed by 2V0-731 - once you've passed both you'll be VCP7-CMA certified, so long as you've also met any training requirement for VCP7-CMA.

Not the driver issue but an issue in the virtual device layer. The device does not work with WS as well. I'm still looking.

Need PowerCLI script to pull actual size of thick provisioned (lazy/eager zeroed) disks

Hi,

 

Can you please let me know if there is a PowerCLI script to report on actual space (not the provisioned space) of any thick provisioned disks across a vCenter.

Uman

Re: Error : No valid host was found. There are not enough hosts available. Code 500

Hi,

The plot thickens as I dig deeper with your tasks send me on.

So what I found is this: I searched this and it relates to failed deployments, patches or upgrades. But remember its up and running we just cannot provision or restart an Instance.

 

Also does this screen mean it still thinks it's in deployment limbo? What would happen if I click "Stop Openstack Deployment" here?

 

 

Here is the status: I think a better question is what command line utilities can I check to validate this environment? Or as you stated "should check the status of your deployment," Like (openstack-status)_ on Redhat?

 

Thanks

Jeff

You will be able to physically apply the license on the new VC. The licenses must be removed ASAP from the old VC instance otherwise you will be breaching your VMware agreement. It will work though and you will be able to "roll-back"

Thank you, it worked for me.

Snapshots of Writable Volumes

0
0

We are looking in to creating a solution for users who want to be able to "roll back" their writable volumes to a certain point in time. One example of a scenario is the user wants to upgrade an application installed in their writable volume and want to be able to roll back to the previous version in case of failure. Storage xnapshots of the LUN the Writables are stored on is a solution but restoring via that method is cumbersome. Can anyone suggest any other solution? Can a snapshot of the VM in which the writable is attached to be taken and then reverted if need be?

Thanks for your reply Scott.

I have be learning VCA-CMA followed by fundamental course in VM ware leaning zone. As you said VCA alone will not have any value so I am planning to take a course for vSphere 6 fundamentals first and later I will go for VCP7. But will I be certified by VM ware for passing a vSphere 6 fundamentals exam alone ?? I know it is a silly question but I want to clarify myself...
