• Change the block size? vSphere ESXi 4.1.0.

  Hello world

  I wanted to create a third virtual machine, but the existing computer hard drive was large (GB 266), because I had created a VMFS with 1 M block :-(

  I searched a lot of log and manuals, but I couldn t find an answer, how to change the block size of the data to 2 M store.

  I m using vSphere ESXi 4.1.0.

  Then I tried to export the VM´s to set up the new host of VM with another block. But I m not able to find a filebrowser in the vSphere Client.

  How to export or save a virtual machine or a snapshot.

  In the FAQ, it is described to "Open the filebrowser", but where it is hidden?

  Thank you very much for your help.

• Changing the block size of 8 MB on local hard disk in esx 3.5 u4

  Hai

  I want to adjust the size of the blocks of the local disk block size is 1 MB, I want it 8 MB so as to p2v a 600 GB machine in to the esx host has 800 GB hard drive. I know the following command

  To change the size of the block of the vmfs file system, you must use vmkfstools to reformat the partition. The command is:

  vmkfstools - vmfs3 - blocksize 8 M vmhba0:0:0:5 createfs

  but this command returns an error to handle attention I think that this command does that for logical unit number not local hard drive of the esx hosts tell me how to change the size of the block of your local hard disk in esx not lun

  VAMSi

  Under ESX / Setup / storage, you need to remove the data with the wrong block size store (don't forget that you have a backup of your virtual machine).

  So simple, you can choose to add a new data store (link on top-right), you will see free space (the old leaves) and you can choose the size of the block.

• How to shrink thin comments on VMFS5? or change the block size?

  Hi all, I'll try to find a way to reduce invited bloating thin-set in service in an environment VMFS5 all.

  We went from 4.1 to 5.1 and then also vmotioned storage all our newly created vm VMFS5 volumes before you delete the old VMFS3 volumes.  During this operation, everyone has forgotten that one of our volumes has been intentionally assigned to a block size of differnet than all the others for the purpose of narrowing of the guests who had swelled upward for some reason any.  Now, we have no way to create something other than a volume of 1 MB block size which prevents us from doing the cleaning routine.  Is there an alternative way to shrink a guest who does not put offline?

  For those who do not know the procedure that I describe, here's how it works:

  You have a 100 GB comments that has only 10 GB of actual data in it, but because of something after bad temporary files, cleaning up old data, etc., that 100 GB had been used at a point of real files but is now only 10 GB in use. You want to recover which is now 90 concerts waste of space because your thin provisioned VMDK is sitting there at 100 GB in size.  With VMFS3, you could create a volume with a block size that was different from that of the volume on which the guest is currently living.   In our environment were all our 1 MB LUN but one that we kept to 2 MB just for that purpose.   When we were getting a little low on space and found guests such as the one in question, we would run a simple command to write zeros to the entire free space:

  Cat/dev/zero > bigfile; RM f bigfile

  Then all you have to do is storage vMotion the guest at the volume of 2 MB and return to its normal domestic and suddenly the VMDK's 100 GB up to 10 GB, all with no impact on the guest.  Without support for the creation of a file system with a different block size in VMFS5, now I'm not aware of a way to reclaim this space in a way that does not require an interruption of the guest.

  You can select the VMFS version when you create a new data store. With selected VMFS3, you will be able to specify the desired size of the block.

• Change the block size of 1 MB (4 MB or 8 MB)

  Hi all

  I'm in a delemia.  I have an ESXi installed 4.1 vSphere but I used the block of 1 MB by default when the size isstalling ESXi.  I have turned Virtual Machines for some time on this topic and may not all simply re - install the ESXi again.  I am currently in need greater than 256 GB drives in my virtual machines.

  What I read for possible patches to change the 1 MB to 4 MB or 8 MB data store to support more than 256 GB drives is to add to the new temporary HDD on the server and create a new store of data on it with the block size of 4 or 8 MB and then migrate the virtual machines to the new larger block size datastore.  Then re - initialize the original 1 MB data store such as a 4 or 8 MB and migrate to the original data store.

  Two questions about this:

  (1) is my eventual detailed correction?  In other words, I add another, say, 8 MB block size datastore, although I have implemented the ESXi server as a 1 MB? Or will it just automatically initiaize the new temporary data store like 1 MB anything?

  (2) If this correction is possible, the passage of the VMS in a data store from 1 MB to 8 MB data store will have reprecussions?  In other words, move a Virtual Machine with the 1 MB block size to a data store with 8 MB is a problem with this virtual machine?

  Any suggestion would be great.

  Thanks in advance.

  Welcome to the community,

  You can format each data store (which is just a partition with a type of VMFS partition) with a different block size and move the VM back if you wish. However, if your hardware supports ESXi 5.x, this can be an easier way to solve the dilemma, because after the upgrade to ESXi 5.x, you can also upgrade the VMFS3 data store to VMFS5 which supports the file (virtual disk) sizes of up to ~ 2 TB with a unified 1 MB block size.

• Change the block/file Max size

  When I formatted my storage I accepted the default size of the mã¡XIMUM file and the size of the block. I didn't know this would limit the size of my data stores (I thought it was just the maximum size of a file). Is there anyway to change on the fly, or do I have to all off svmotion and then remove and re-add the storage?

  Thank you.

  Data store/logic unit number would be limited to 2 TB - 512 k in size (through ESX/ESXi 4.1 u1/VMFS 3.x). Depending on the block size, you went with, VMDK files will be limited to a maximum size. As 256Go with a block size of 1 MB. If you need larger files VMDK, then you will need for storage vMotion VM off the LUN/store data, reformat/recreate the LUN/store data, then they go back on it.

  This is part of a proper planning in the way that you set the LUN... If you need to have 500 GB VMDK files, then do not use the block size of 1 MB. Similarly, do not use the size of block 8MB if you have<256GB vmdk="">

• change the block size to SAN LUNS?

  is it possible that I can change the size of the block on a SAN LUN (whether SATA, iSCSI or fiber) with the help of a vCenter?  If not, what is the way to do it?  Or, our administrator SAN should do?

  It is easier in vcenter - once the vmfs data store has been deleted data from the data store vmfs to remove and re-create it with the correct size of the block.

• How can I change the default setting of font size and type when using e-mail?

  When sending an email, I have a default setting of the Arial font to 10 points. If I change what it comes down to Arial next time I use it. I don't know how to change the default setting.

  Hi Robin,

  What e-mail program you are using (name and version)? Windows Mail, Windows Live Mail, Outlook, a program that you access through your browser (and if yes, what name and version of the browser?) something else (and what version and/or year of this product)?

  What Version of Vista you are using (for example, 32-bit Vista Home Premium SP2 or other)?

  Thank you!

  P.S. I am pretty sure that the procedure is simple and can be done-, but it varies depending on whether you use, so I want to provide the information that is applicable to you.

• How to change the name of a volume iSCSI target?

  How the name of a volume iSCSI target can be changed?  I created a volume with a typo in a letter.   The volume production data on it now so I can not just it delete and recreate the problem.   It's not a big deal, but it doesn't look good either.

  It's on a PS6100.   When I go into the properties of the Volume in the advance tab I can see the iSCSI name, but cannot change it.  All I change is the public alias.  But it does no good that the name appears in the vCenter with the misspelled name.

  So how can I change the iSCSI name?

  Or am I stuck creating a new volume and telling them to migrate their data for spelling can be fixed?

  See you soon

  Part of the iSCSI specification is that target names must be unique.  Therefore, once created, you cannot change the name of the volume.

  Kind regards

• To access the servers non - VMFS volumes ESX (i)

  Suppose I have a FC LUN with a VMFS volume.  It is not accessed by a host ESX (i).  However, there are old VMDK on the logic unit number I want to recover.  If the LUN is delivered to a physical Linux server, and this physical server is zoned / correctly mapped to the FC LUNS, can I access the VMFS LUNS for the vmdk off of it?

  Thank you

  Yes.

• Reading has changed the blocks?

  I'm stuck on how to read the actual changed blocks of a host/vC.

  I called QueryChangedDiskAreas and return a list of (start, length)-this seems to be the current byte offsets.

  In looking at VixDiskLib_Read() it seems entered sector.

  /**
  * Reads a string of sector.
  @param diskHandle [in] handle to an open virtual disk.
  @param startSector [en] absolute offset.
  @param numSectors [in] number of sectors to read.
  @param readBuffer [out] buffer to read into.
  * @return VIX_OK if successful, suitable VIX otherwise error code.
  */
  VixError
  VixDiskLib_Read (VixDiskLibHandle, diskHandle,
  VixDiskLibSectorType startSector,
  VixDiskLibSectorType numSectors,
  UInt8 * readBuffer);

  How to merge these two concepts in the possibility of obtaining the actual modified bytes of virtual machine?

  Is it only bad design/documentation of the API and the 'sector' is really a byte (VixDiskLibSectorType is after all a uint64)?

  
  

  Thank you

  Richard.

  Hi Richard,

  I just don't have access to the VDDK header files, but if I remember correctly it VIXDISKLIB_SECTOR_SIZE is defined in vixDiskLib.h. Currently, sector size is 512 bytes. So to convert the lengths and the sectors byte offsets, you need to calculate as follows:

  bytes/VIXDISKLIB_SECTOR_SIZE

  and you should be fine :-)

  Hope this helps
