  Discos sao thick discos totally alocados not store data or seja, to você criar um disco thick com 20 GB, ele will occupy 20 GB go don't do seu datastore, a difference between o e thick lazy Zeroead eager to zero, as e no lazy nao sao written zero em todos os blocos disco, o ele ja eager keys zero em todos os blocos disco.

  Ja disco o think e um tipo disco than aloca only the Espaço e timed pelo sistema invited operational, for example, is você criar um disco 20 GB para uma VM, inicialmente ele go occupy only the few KB/Mo no data store, very no momento as voce ready SMS dados no mesmo don't do sistema operational through o dele pode chegar ate limit o 20 GB size.

  Thick eager willingness to zero: usually used por VM as ARIO use a Fault Tolerance funcionalidade do VMware, or to use a funcionalidade do Microsoft Failover Cluster dentro das Máquinas tolls;

  Thin provision: usually used quando para is provisionar but Espaço than total o Espaço fisico available, very can cause problems is todas as VMs utilizarem todo o Espaço available data store.

• Eager to thick available zero - provisioned size?

  Buongiorno a tutti!

  Premetto che sto con esxi5 e VMFS5 using all the vm hanno I brain configurati in thickness available eager to zero...

  UNA di queste ha 2 hdd configurati (uno Dadaism 40 GB e altro 1.99 CT) the to do e non riesco instant ads in quanto mi viene restituito error "file is larger than the maximum file size supported".

  Controllando he datastore vedo che solo by da disco he 1.99 CT) nella colonna size e is dimensione 0, 00 KB mentre nella colonna provisioned size leggo 2.147.484.000, 00 KB...

  ORA mi chiedo... being both brain in thickness available eager to zero, should esserci comunque colonna provisioned size? E inoltre, e questo he reason per cui non riesco instant of the ad do?

  Grazie in pre-empted a tutti!

• Convert PowerCLI ESXi 5.0 thick eager lazy zero at Z fails

  Greetings...

  PowerCLI version 5.0

  5.0 U2 ESXi hosts

  vCenter 5.5

  
  

  I'm moving virtual machines from a data store and change of type of disc to thick on zero eager lazy to zero. The following script keeps failing.

  
  

  Any ideas? or point me to the discussion that can help here please?

  In PowerCLI 5.0 in thick format zero eager was not a supported option. There is the 5.0 doc)

  ( https://www.vmware.com/support/developer/PowerCLI/PowerCLI50/html/Set-HardDisk.html) display without option of EagerZeroedThick. PowerCLI version 5.5 or later EagerZeroedThick was available)

  ( https://www.vmware.com/support/developer/PowerCLI/PowerCLI55/html/Set-HardDisk.html)

  If you can I suggest that you upgrade to 5.8 PowerCLI (works perfectly with vCenter 5.5 and 5.5 VUM) and then you'll get what you need and can be used with your 5.0 hosts without any problem. 6.0 is the last, but the Crossover components are version specific (i.e. 6.0 Update Manager for PowerCLI can not handle the VUM 5.5).

  Otherwise, you will need to use the underlying API rather than the easier to use cmdlets

• Is it possible to convert thick Lazy set to zero to Eager to zero online

  Hi all

  I tried to clone model 2008 windows with 50 GB drive OS which is resetting eager disc type. The cloning went well and I tried to expand the size of the OS 50 GB to 80 GB disk before first BONES begin after cloning. After the action, I found that the disc type is automatically changed eager reset to Lazy set to zero. I wonder why would change the disc type. And is there a way to re - convert the disc type of lazy to zero in a hurry to zero online? And if online is impossible, is there a way to do same re - format the disk is necessary? pls help.

  Please take a look at http://kb.vmware.com/kb/1035823 which explains this in detail.

• My ipod said zero KB available and used zero KB. It does not synchronize without going into an endless loop.

  IPod Classic 160 GB to 2009.  Will be out of sync without going into an endless loop.  Settings on Ipod suggest zero KB used and zero KB available.  No music is on IPOD even though I had over 5000 songs on it.

  1. is this a hard drive failure?

  2. If I I I fixit?

  3. it cannot be replaced as Mr. Cook wants me to buy more new Apple toys which will be break and not be supported.  Best advice?  (BTW, the sarcasm is due to a Imac turns is not on and engineering said: I had to buy a new computer my Imac was too old and is no longer supported.)  Tired of this song.  ((  )

  1. very likely given the age

  2. not worth your time

  I had an original iPod classic that lasted nine years, but eventually had to replace it. No material lasts forever.

• NFS and allowed FT VM?

  For FT it takes kind of disc VM to be thick Provisioning eager to zero but when choosing the datastore NFS for files of virtual and thin and thick machine Options are grayed out and I know that FT is supported on NFS, but my question is how if she needs to disc thickness and this option is grayed out? Anyone who can help me with that?

  You will need to ESXi 5 (or later version) and your NAS provider must support NFS space reservation, to do this.

• Increase in the size of the number disc scratch thick eager

  As I increased the size of the disk of thickness eager to zero, and after that he changed to lazy thickness to zero. Why is it changed. Anyone who knows this problem.

  This problem occurs if the values are not updated in vCenter Server, this article talks about it: VMware KB: space Provisioned may seem incorrect in vSphere client view of the inventory of Virtual Machines and the solution to this KB, that's what you already have.

  BUT, you can reload the .vmx withou delete the virtual machine inventory, take a look here: VMware KB: reload a vmx file without removing the virtual machine to inventory

• Thin vs. lazy thickness set to zero + SAN thin provisioning

  Is there an advantage to using thick lazy set to zero and then using a provisioning to the FC LUN by opposition level just using Vmware Thin provisioning?  I guess I could use thin for VMS and LUNS, too.

  Updated zero lazy thick result in less lock/delay when filling unused space from end

  I don't think we see any economy using eager Zero thick with San provisioning on our Netapp.

  You should see the original in vsphere, but thin format discs on your San.

  Maybe this will help.  http://theithollow.com/2013/03/are-you-thin-or-thick-where-at/

  • If the virtual disk VMDK is a Thin, convert the eager Zerod drive of the thickness using the vmkfstools --inflatedisk command. For example:

vmkfstools --inflatedisk /vmfs/volumes/DatastoreName/VMName/VMName.vmdk
    
    Note: the command of inflation indicates the percentage of completion.
    
    
  • If the VMDK virtual disk is thick, convert the drive eager to zero thickness using the vmkfstools --eagerzero command. For example:
    
    vmkfstools --eagerzero /vmfs/volumes/DatastoreName/VMName/VMName.vmdk
    
    Note: the avid zero order does not indicate the percentage of completion.

  1. do I need to run the two commands?

  2 will. that affect data on these discs?

  Hello.

  The disc is not thin provisioned (thinProvisioned = false), then the command ' vmkfstools - inflatedisk ' is not necessary.  Running the ' vmkfstools - eagerzero "command should not affect all data on the disk, but it is always a good idea to make sure that you have a backup before you run all disk commands.

  Good luck!

• Is active FT disk = eager disk set to zero?

  Is it true that if activation of FT option when creating a new virtual disk that this record will be a "record of zeroing eager?

  Would there be any problem by ticking the FT, even if I don't hear any real uses the functionality of tolerance to failures, but for some reason any disc is eager to zero?

  Yes. Active disk FT is "desirous of thickness to zero."

  If you enable FT for VM with standard thick or thin discs - all disks will be converted to eager to set thickness to zero automatically.

  > Would there be problems

  N ° but it would take considerable time to create these discs, unlike the standard which are born almost instantly.

• 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

• CBT on zeroing keen records

  Hi all

  If a disk is configured using thick eager to zero, the CBT will review all areas of drive in use and to back up the entire disc rather than only the disk space used? How does it work? Please share your ideas

  
  

  Thank you

  Ali
  

  > If I understand it, then it means that if a drive is configured using thick eager to zero, the CBT would consider all sectors of disk is in use so to backup the whole disc rather than only the disk space used.

  This case is only the theory - in the normal conditions of use, you first create the disk - and then a little later - you create a backup job.

  So, the starting point for the CBT database is generally a disk populated.

  Only this case would be: you start with an empty disk implemented end - and then create the first complete backup before you even installed an operating system - and then you blow up the thin disc put into service for the nominal with a comand as size
  If DD \u003d/dev/zero of = / dev/sda
  Now that can cause the issue you think - although even now CBT guess probably that blocks not allocated in a thin vmdk can be considered to be in the same State as the blocks of same wiped with zeros after inflation or a dd command

• Thin Provisioning vs thick Provisioning

  Some users say they are not too Committee a disc thin provision.

  But I think that if they are not over - commit then how are they case using the benefits of provisioning. Instead why don't they use thick available?

  You guys agree with my opinion?

  I agree, if there is enough disk space, thin provisioning is basically no benefit to this transfer.

• Novell GroupWise 2014

  I'm looking to start a new SLES 11 SP3 / server OES 11 SP3 on my server ESXI 5 works in 2014 of GroupWise.

  I'm sure that the server its self should be thin, but I was wondering what type of supply to drive, the NSS, which will store my GroupWise system that will give you the best performance.

  Also we have only 25 users, so I was wondering what would be a good configured as a virtual server (number of processors / cores / Ram).

  Thank you

  Ken

  Ken,

  Because GroupWise is all I/O I'd be eager to thick available zero readers. This way it will be already be put in service, so no extra fresh General when space is needed. Any loan will be there.
