Thin Provisioning LUNS and virtual disks

• Thin provisioning / "right-size" database disk

  OK, so I have the setting permissions and ready to deploy to the device.  I don't want to have a 200 + GB DB hard.  I know they say there is a special way, using the OVFTool application if you are using vSphere 4.0.  We run vCenter 4.1 and 4.1 ESXi hosts.  To specify the hard size I want, will it still thinly provision the device with the OVFTool?  I'm looking for clarity in this before deploying the machine, because I will be setting LUN space based on drive of 75 GB database (with room for future growth in LUN).  I apologize if this has already been covered, but I didn't see any other posts related to my question.

  virtualhudak,

  Technically, you should be prevented to deploy the virtual appliance CapacityIQ on a LUN with only 125 GB of free space on the disk.

  You need a data store with at least 258 GB free space on the drive in order to deploy the appliance CapacityIQ. That you complete the deployment wizard, two of the questions asked are if you want the first disk to be configured as a disk, thin or thick. and the same question for the second disk (/ data).

  Once you have deployed the virtual appliance successfully, you can follow the steps to reduce the size of the second (/ data) disk.

• Acer Aspire V5 - 572G windows update, net and virtual disk problems.

  So I installed w7 x 64 ultimate on my laptop and notiiced windows update does not work. It shows that he can not connet to the server. After trying to fix it I discovered that I need to install net framework, which I tried, but he also failed because when I download the framework and before I press on install it shows me how much to download and it is 0. After I press on install it loads a little and it is said that he was not successful. Also tried to download some programs, such as driverpack, drivers search for and he found this lack gcdbusdevice and dcbusdevice im. When I tried downlaoding them, they seem not to exist. And when I try to install daemon tools or some simillar programs, it will fail to install, or fails to create a virtual disk, and after that the laptop can not stop lights. I have to use the restore point, and then he turns then on.

  So yes, some advice or help would be nice, thank you.

• Newbie question on merging 3 - Windows 7 (upgrade) and virtual disk

  Hello

  I apologize if these questions were discussed on other threads, but I looked and did not find those specific to what I do. Since I am a new user, my experience with the merger is limited only to the few days of operational use.

  I received my iMac the other day and wanted to install Windows 7 (upgraded version) using Boot Camp and access either by booting natively to Win7 or through merger to access the Boot Camp. My friend, who has more experience than me has suggested, I use VMware Fusion for Win7 do run a vitural drive and not worth using Boot Camp, and a "hard" partition He said it would be faster and easier to manage (not sure now).

  I set up a disc in this drive and external created 4 partitions, which was intended for Win7. Then I installed VMware Fusion on iMac and went on loading windows on the external drive using the easy method. Easy installation application the activation code for Win7 and I provided at the specified location. Everything was humming along nicely until Windows 7 complained that he could not find a version support for Windows earilier. I had a Windows XP genuine disc ready to throw on the iMac, as soon as she needed, but instead he has cancelled installation.

  Then, I went to Google and searched for some answers and discovered that Win7 install in Fusion without an activation code. I uninstalled VMware and reinstalled, restarted the process, do not put in the Win7 activation code and everything was fine... except now, there is no Windows activation request. I've searched and anywhere to click on a link to activate Windows, or indeed could not find a place to write in the activation key.

  What is happening with this?

  Ron

  Windows installation without a product key is convenient to have more options to activate Windows later.  Don't worry, Windows will "ask" you activate in the near future, but if you are willing to 'true' then go to properties of the icon of the computer and at the bottom you will see the activation state and you can change/enter your product key.

• need to know the size of the delta.vmdk a snapshot of a virtual disk 2 TB

  Can anyone help please?

  I need to know the size of a snapshot for a virtual 2 TB drive.

  Unfortunately I can't create one myself as ESX does not create a disc of 2 TB provisioned end if the data store has only 600 GB of free space.

  If you have enough free space on your storage space can you please do me a favor?

  Create a new virtual machine with a 2 TB drive thin provisioned - when the virtual machine has been created please use snapshotmanager and create a snapshot.

  When done it please download the snapshot and zip and attach it here.

  Thank you very much

• Partition 32G BootCamp, Virtual Disk - flat hard 125G file!

  Hello

  I recently installed VMWare Fusion on my laptop OS X I have created a BootCamp partition and installed XP. I created a partition of 32 GB for XP. I noticed my OS X partition to fill quite quickly. I used "from" to find the culprit and it's a 125 G file created by VMWare Fusion! Is this normal? This seems excessive. The file is located:

  / Users/tammy/Library/Application Support/VMware Fusion/Virtual Machines/Boot Camp of Camp/%2Fdev%2Fdisk0/Boot partition.vmwarevm/Virtual disk - flat hard

  Is it possible to get a little less of my OS X Fusion disk space use?

  Thank you.

  Tammy

  Well, I had to do a little research and what I found out, is that you can not directly mount a virtual secondary drive while he lies in the Boot Camp Virtual Machine partition and I've tested this with both one unformatted and formatting virtual hard drive and got the exact error and message in the absence of additional information in the log file then here is what you can do.

  You can modify the Boot Camp partition.vmx change ide0:1.present = "FALSE" ide0:1.present = "TRUE" then boot partition Boot Camp Virtual Machine and see if the disc is visible in Windows Explorer and if it is not then it has not been formatted and contains nothing, in which case you can remove it from the virtual machine and leave within the Boot Camp partition Virtual Machine package or...

  Move the file Disk.vmdk virtual and Virtual Disk - flat hard to the desktop, press ctrl + click on the Virtual Disk.vmdk, and then select open with > VMDKMounter and see what message you get if any.  If it does rise and you get an error message appropriate then it can be deleted safely

  Understand that even if I know it's a pain in the thigh but I need something technically absolute that is within reasonable limits, before I will advise someone to delete a virtual hard disk and I hope you understand the reasoning and wisdom behind this!

  I forgot to mention that if you choose to modify the Boot Camp partition.vmx this must be done with closed merger.

• Reference Dell HDS - recommended VMware virtual disk - drives provided - basic and dynamic thin and thick.

  Can someone point me to the literature on best practices for guest disc formats?

  I know all the Compellent thin-provisions. However, in VMware 5.5, when you set up a virtual disk in the comments you have several choices:

  • Lazy provisioned to zero thickness
  • Eager provisioned to zero thickness
  • Provision of thin

  And then, at the level of the OS, you have the choice of:

  • Base
  • Dynamics

  I would like a pointer to the technical document explaining the advantages/disadvantages of each choice and recommended best practices.

  Kind regards

  Kath

  I would like to either thin or thick lazy to zero.  The two will take the same amount of data on the HDS.  The main decision is where you want to manage your storage space?  If dilute you on thin you need to make sure that you make no provision in both places.  If you have thick lazy to zero, then you can only on commissioning on one side.

  Say that I always thin on thin.  Recovery of the space at the level of the virtual computer is not officially supported immediately, but maybe someday.

  In a virtualized environment, always keep it simple.  There is no dynamic performance with virtualization

• Is it possible to migrate a virtual machine to thin provisioned disk?

  I have about 100 VM in a resource pool dedicated to called "Archive"... Well, archiving.  These virtual machines are currently powered off but every now and then we will get pulled for a developer to work on (they are for the most part, the virtual computer with client customizations if they are changed about once a year).  I'm quickly running out of space on this SAN but all discs are thick provisioned and using the disc is maybe 20-30% on average.  Also, I want to move them to a new large store of data I created for them.

  Of course, I choose Migrate & gt; Change store data & gt; Thin provision in vSphere Format and I'm done.  However, it would be nice to not do this 100 times.

  Move-VM does not seem to be capable of this, and I have not been able to find a workaround.  Is there a way to convert the thin and then perhaps Move-VM? Or I'll just on this all wrong.

  Thank you!

  You can try this script?

  He's moving vms to data store 'EMCSAN:Datastore01' trying to change the format of storage for Thin

  $dsView = Get-Datastore -Name "EMCSAN:Datastore01" | Get-View -Property Name

• Backup errors with backup of thin provisioned disks on ESXi 5.1

  Hello

  I try to set up a backup solution for two servers in ESXi 5.1. (free version).

  I have installed and configured the ghettoVCB successfully and everything seems to be ok.

  However, when I start to create a backup, the process would end with an error :-(

  It didn't matter if the server is enabled or disabled, I get the same result.

  All data warehouses are local, 2 x free WD500GB with plenty of space.

  There is no snapshot, anything that could (in my eyes) prevent a good backup.

  The server works perfectly, when turned on.

  I'd appreciate any useful comment. Thanks in advance! The log is attached.

  > However, when I start to create a backup, the process would end with an error :-(

  This is not correct.  Depending on your position, you've got to 66%, until he ended with an error.

  I have the same problem. In my case, I make a virtual disk full and mount it with Server 2003 for project a NFS volume.  I use GhettoVCB, as you do.  It uses the standard vkmfstools in the script to make the clone/backup.  I have proven that the problem also occurs when you use the command line vkmfstools.  GhettoVCB has the bad habit of you cache the error code.  The error code is he ran out of disk space, which we both did not happen.  Once the problem occurs, the only way I could fix is to delete the virtual disk and start over, however, the problem will come back.  The problem didn't surface until what I moved to ESXi 4.0 5.1 on the servers.  Through this process, the hardware off the VMS version did not change, nor dare, because I may need to take 5.1 and back to 4.x.

• thin virtual disk have full size allocated - seems

  I have created a virtual machine with the thin disc type, give it a capacity of 500 GB, install the operating system and its actuall size is 3.60 GB I can check of Vsphere, the disc name is "vmname.vmdk".

  now I want it moved to another server esxi, but when I started downloding, its size became very larg and reached same 171 GB of the drive was renamed "vmname - flat hard"(sur où j'étais le téléchargement) and ends my disk space on the local computer where I was downloading, how I can upload and download with the same size means 3.60 GB "» ,

  Please guide me

  Welcome to the community,

  provisioning is a feature of VMFS file system, this is why the virtual disk inflates its provisioned size when uploading it. What you could do is to export the virtual machine (file-> export) as an OVF and import it on the destination host.

• New features of Clustering Option VM and Thin Provisioning

  First time post here thank you for patience. I have ESXI 4.1 Essentials Plus, which allows me to have a HA. When I create a new virtual machine he asks me if I want to:

  "Take features of Clustering such as FT.

  This option needs to be checked for HA to work? I want to provision thin, but not at the cost of losing HA.

  No need to enable support for HA FT to work. Also your vSphere edition does not FT.

  Simply select thin provisioned disks and you.

• Cannot increase the size of thin provisioned disk

  Hello

  I am currently using vSphere, and I have a server that I am trying to increase the space allocated 40 GB to 50 GB. The problem is the option to increase the provisioned size is grayed out and I can't seem to understand this.

  I already checked to see if there is a snapshot, there are none.

  I also checked that the drive is a scsi and NOT an IDE drive.

  I'm fresh out of ideas and google searches return only guides on how to do what I've done, so any help is appreciated. Attached are the parameters of the hard disk, and the Snapshot Manager shears.

  Welcome to the community,

  According to the file name of the virtual disk in the first screenshot, the virtual computer runs on an active snapshot. The Snapshot Manager can not always show all snapshots, then take a look at the data store of the virtual machine to see if there are files... - 00000 x hard (snapshot).

  To get rid of the snapshots, create a new snapshot and run "Delete All" since the Snapshot Manager to commit all the snapshots on the basic disk.

• Question about thin provisioned disks

  I did some searching but can't find specific answers, I need and I apologize in advance if these questions are public knowledge. I know also my setup is very small compared to most houses VMWare normally using these forums, but we are moving slowly in the 2nd Decade of the 21st century (or try).

  I have a new install ESXi 5 and move during one ESX3 host that has about a dozen of VMs on it.  I recently built vCenter host servers and my future view connection server.  I'm kind to vCenter again as my previous installation of ESX 3 was a single server and us were not investing in the vCenter at the time option (missed a lot of features and ease of upgrade during this transition, but 20/20 declining).  I'm a little green in using vCenter so take pitty on my ignorance.

  It's more time than I wanted to and I just want to know the best way to change these 2 servers (recently built and configured systems Win 2008 R2) to thin provisioned disks.  I need to keep all the storage space I can and beyond the obvious problem of being able to provide more space than you physically, I have no problem to do so (in addition to get them changed).  If there are negatives I'm missing, please report them to me.  The possiblities that I see are:

  The clone and thin provision then delete the originals.

  Use the stand-alone converter on them (from above).

  Completely rebuild thin provisioned with disks.

  If someone can give me a quick list of possible problems and pitfalls for these opportunities or to get to a better suggestion, please do so and thanks in advance.

  Manual of Clark

  PRIMOS Inc.

  Since you have storage vMotion the clone or standalone VMware converter are both viable options.   Not sure about the disadvantages of these options.

  You didn't say what kind of server it is, but I'm always careful about the cloning of the domain controllers.   Without the option for storage vmotion I rebuild a DC from scratch.

• Thickness as Thin provisioned disks

  I had a strange situation this morning and I hope someone can shed some light for me.

  I have a virtual server with several big (300 GB and 200 GB) HARD drive.  The two HARD drives were created as thick put in service, as I recall they show also thick configured in the properties of the server.  The data is stored on an iSCSI SAN.

  This morning, I came to find one of my virtual servers had been frozen as he had ' not enough space to write.  I looked in the store and found the property that the disks have been configured in thick they are infact behave more like thin disks.  In the store, they show that 110 and 202 instead of 200 GB and 300 GB.

  Any thoughts?

  The screen capture, it seems that your VM has 3 virtual disks (~ 256GB, 60GB, 350 GB). The size of the snapshot files (the screenshot doesn't show timestamps), I guess that there has been a problem some time ago (one of the snapshots already is ~ 67 GB in size) with delete snapshots after a backup operation.

  You must take immediate action to get rid of snapshots! However, to know whether to save just delete catches instant in the Snapshot Manager (it can currently not display any shots even if you have a little) I need to know what version/buils of ESX (i) you are running and the amount of free space on the drive you have on data stores different (the virtual disks are located on different data stores)!

  Currently, the virtual machine works without problems?

  Please join (not paste) the last file vmware.log file for the virtual machine (see the screenshot).
