• ESXi 5.5, 5 VMFS datastore / vmdk size question

  Trying to check that I understand the vmdk for esxi 5.5 size limitation.

  If I have a VMFS 5 existing on my 5.0 esxi hosts, data store once I update my hosts to esxi 5.5 that I would then be able to have vm with vmdk is greater than 2 TB?

  I don't have to create new warehouses of data VMFS 5 after the upgrade to esxi5.5 take advanrage of the change in file size limit?

  Thanks for any help.

  That's right, at least in part. In addition to the upgrade of the host, you must also upgrade the hardware version of the virtual machine (Compatibility Mode) to take advantage of larger virtual disks (up to ~ to 62). However, always keep in mind the time needed to restore the virtual disk together where this is necessary. With 1 Gbps - assuming that you have the full available bandwidth - 2 TB will require more than 5 hours already! Then maybe organize the data in several virtual disks may be a better solution.

• 1.8 to VMFS watch block size of 1 MB - WTF?

  We have a box 4.0 on which we have created multiple VMFS, each about 1.8 TB volumes.

  All three volumes appear and we have been using them, but today we came to increase the size of a VMDK and found that he maxed out at 256 GB.

  By looking at the properties of VMFS volume, all three show that 1.8 to, or one of them (one is this VMDK) shows a block size of 1 MB.

  By definition, if I understand correctly, you cannot have a 1.8 to VMFS with block size of 1 MB, so what is the best way to combat this?

  The server is a stand-alone, so it is not shared storage, nor is the server connected to a vCenter server.

  Thanks in advance.

  Block size does not affect the size of VMFS, it only affects the maximum size of the single VMDK file. So, it is perfectly valid to have datastore VMFS 1.8 to with 1 MB block.

  You must evacuate all virtual machines that store of data and reformat the drive with the largest block, I'm sorry, but it's your only option.

• NFS VMDK size limitation?

  What is the limitation of the size of a single VMDK carved into a NAS data store? I realize that the default out of the box VMFS data store is created with 1 MB blocks so a limit of 256 GB. But what about a NFS datastore? The default seems to be 256 GB, but I wonder if there is no setting on the side of NFS as there are on the side VMFS with changing the block size.

  I was digging around and I can't find anything. I see the size limit of 16 TB, but no sizes vmdk documented data store.

  VMDK size is limited to 2 TB less where it is.

• VMFS and VMDK compatibility

  Hello

  I have a number of ESX 3.0.2 - Update1 host I do fresh installs of ESXi 4.1 on. The 3.0.2 hosts are connected to the external storage where is stored the VM and data warehouses. ESXi 4.1 is compatible with the version in the format/VMFS and VMDK/version of the format of the existing data? Guests of ESXi 4.1 will be able to set up warehouses of data and power ok the virtual machine?

  George.

  There are two things to look at. The first is the version of the VMFS file system, which is - as you say - 3.21 VMFS, so it's ok. The second is version of virtual equipment of the virtual machine, which must be at least 4. (see http://kb.vmware.com/kb/1003746) With ESX 3.02, this should be the case.

• VMFS 3.46 size

  Hi all

  I have v-sphere 4.1 and one of my virtual machines a hard disk 450 GB question is it possible to increase it to be 1 TB

  When the file system is 3.64 VMFS

  Thank you for your support.

  Your vmfs must have at least 4 MB block size to have 1 TB vmdk, and of course you need free space in the data store.

  Choice of block VMFS3 size & Volume limits:

  Block Size Largest virtual disk on VMFS-3
  1MB 256GB
  2MB 512GB
  4MB 1TB
  8MB 2TB
  

• Complete zero to VMFS and vmdk using vmkfstool w

  Hello community,

  We are studying now "Zero detect' function on IBM SVC Thin provisioning.

  SVC Thin provisioning Volume is unable to note removal of file on VMFS, so we need a way to fill blocks, we don't use on VMFS with zero.

  Can we apply "vmkfstools w" command to VMFS?

  We know that this command is vmdk, so that we can create or translate vmdk format to another.

  but we do not know that this order may apply to VMFS or not.

  We managed to run this command for vmdk(/vmfs/volumes/xxx/xxx.vmdk) and cannot run a VMFS (/ vmfs/volumes/xxx) on our environment.

  Anyone know this specification?

  afalk, vmkfstools you can only ask vmdk only.

  For writing on a lun, can use DD.

• VMDK size is not equal to the size of the comments

  I'm using vmware workstation 7.13 and build a virtual machine with win xp as a guest operating system.

  I put the vmdk as thin provision with size max 15 GB

  inside the guest os he say she used 2 GB (I check the size of the vmdk file in the host and the same 2 GB so)

  then I test the guest operating system by placing a large file (about 3 GB) and to increase the size of altogether 5GB vmdk

  but when I remove the 3 GB file which resident in the guest operating system, the size of vmdk are 5 GB

  so the question, not the size vmdk is not resize depending on the size of the guest?

  I tried to compact and defragment the vmware workstation tools vmdk file, but it does not change the size of the vmdk file

  I put the vmdk as thin provision with size max 15 GB

  Thin configured virtual disks are for ESX 3.x and higher and cannot be created by the user of VMware Workstation interface.  The user of VMware Workstation interface creates Sparse or Growable type virtual hard drives.

  I tried to compact and defragment the vmware workstation tools vmdk file, but it does not change the size of the vmdk file

  Free space must be cancelled before the shrinkage and compaction to a virtual hard drive and this is accomplished by using the function of narrowing of the VMware Tools in supported operating systems and file systems or other methods of zeroing free space should be used first, and then compact.

• Is reset or restart the virtual machine should all expanding vmdk size?

  Hi all

  While extending the size of 20 to 28 GB GB vmdk I can extend when the VM is in poweron State, but he didn't think inside the virtual machine. The disc is resized when the virtual machine won reset or reboot.  I would like to know if the reset or restart that virtual computer is must have for resizing vmdk. If it is then what is the use of expansion of disk while the VM is in poweron State?

  Thank you

  Vijaya

  Yes with windows 2008, you can extend the OS disk to create a new drive letter instead.

  Here is a tutorial: http://www.petri.co.il/extend-disk-partition-vista-windows-server-2008.htm

• Local storage VMDK size recommended

  At the time we were in VMware server, we were in charge of keeping virtual disks on our hosts relatively small (about 20 GB or less) and just add more disks to the virtual computer when necessary. The reason being because more large VMDK was unweildy and often caused performance problems. I wonder if there is a guideline like this for ESXi.

  I think that with a SAN disk size becomes irrelevant because they are never actually moved or anything, but with local storage, consider backups and disk performance. All recommended for disc sizes?

  Not exactly order this blog post, I've written should give you some additional information.

• Reduction of machine convert vmdk size?

  Recently, I've converted a physical machine into a virtual machine.  The hard drive on the machine was 150 GB, but only 40 GB is actually used.  How can I remove the space that is wasted?

  I tried to use the adjustment in vmware tools tool, but who don't seem to do anything.

  You must use VMware Converter to do that. Do a V2V and the wizard will ask you to 'change the layout' for your drive

  Type the size you want and let's go

• VMDK size differs from that indicated by the guest operating system

  Hi, my said guest operating system disk hard is full to 30 GB, but the parameters of the virtual machine, it is said the vmdk is currently only 2.4 GB.  Anyone know what could be going on here?

  Configure you the VM to expand on the use and create NOT entirely the disk, it saves space.

  The VM disk is being created in 2 GB increments up to full capacity. And the OS disk is not full, it's (potential) CAPACITY of the disc, the drive was full the VMDK more would certainly be 31.5 GB as well.

• Virtual RDM: mapping in the vm, VMFS folder file size

  Hello

  I just migrated an iscsi LUN previously managed the MS iscsi initiator (running inside a machine virtual w2k03) to ESX iscsi sw, preserving the data.

  I used RDM (raw device mapping) and I had to use 'virtual' because 'physical' hanged the VM at startup of the operating system.

  The iscsi LUN is 1 TB, with about 60GB used.

  I noticed that on the volume VMFS file mapping for the virtual machine is about 2 GB: happen when on the iscsi LUN more space will be used? And if it goes, is there a rule to calculate how much?

  I'm worried I might risk running out of space on the VMFS volume because of the mapping of RDM file...

  Thank you

  Guido

  It's just a pointer to the original disc of RDM.   I have a few MS Cluster in my setup. For 18 GB RDM Lun he creates about 100 MB.

  Thank you

• VMDK size

  Hi all, I use linux opensuse 11.1 with vmware player to start a windows XP... I would like to know which is better for performance... have a single vmdk filed with 20 GB or have a lot of files vmdk with 2 GB each.

  Best regards...

  The performance difference is minimal.

  I prefer to use other things, like an easier handling and less space required on the host computer to delete snapshots, to decide which drive to use.

  See http://sanbarrow.com/vmdk/monlithicversussplit.html and http://sanbarrow.com/vmdk/disktypes.html for a good comparison.

• 2 TB + VMDK? How...?

  OK, maybe I'm stupid. But for the life of me, I do not understand this.

  VMware said THAT VMFS 5 supports up to 62 to VMDK.

  Yet, when I build the new data store of 14 to SAN LUN with 5.60 VMFS, max VMDK size is 2 TB due to the block size of 1 MB.

  I'm converting a file from a server 10TB server share nu metal to a virtual machine and I really don't want to use Windows dynamic disk to span multiple volumes.

  Help me understand this contradiction?

  You try this VI-client or Web client. What I remember is that only Webclient allows you to create 2 TB + VMDK. Can you check and update
