• 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

  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.

• Help move my datastore on external USB drive to reformat with correct block size

  Hello

  I use a Dell PowerEdge 2650 with a 550 GB disks configured in RAID 5 with ESX 3.5i

  When I installed ESX I didn't pay attention to the size of the block. This is the default 1 MB and so I reached the maximum extends. Which means that I can receive only 260 GB on my 550 GB.

  I need to change the parameter to a block size of 4 MB in order to access the entire table.

  But for this I need to move my existing data store that contains a lot of important files for me.

  I have not any currenty server with 260/300 GB of free space.

  I'll try the following:

  1. connect an external USB drive. I have ssh running, but I'm having difficulties to climb. I looked for info, but I am always sick.

  2. If possible, I would like to compress using gzip great records in my data store before moving. Can advise you on the location of the files in the system and if it is possible to do?

  Thank you

  It is clear now,

  in this case if your VM's you buy a big enough hard drive 250 GB single VMDK file to copy all virtual machine configuration, not he zip or compress, you can screw all of the data on disk

  I have an idea, depends on the amount of data you have on your virtual hard disk, you can use VMware converter 4.0.1 and clone your VM with discs thin provision, Vmware converter will be "zipp" your VMDK file to the exact size of your data without any risk that would have lost you all your data.

  1 use vmware converter to clone your VM with discs thin provisioned

  2. low source VM

  3. start the VM 'new' and check if it works well

  4. If 4 is OK, stop VM 'nine '.

  5. copy the new virtual machine on your USB key (set the USB you your workstation and you winscp to copy the virtual machine)

  6 remove VMFS datastore

  7. create the new VMFS datastore

  8 download VM to the new data store

  9. creating the new virtual machine based on a VMDK file

  10. start the virtual machine

• The guest operating system block size

  Hello

  Although guset OS block size is determined by the ESX Server, is it possible to change the size of the blocks by each guest operating system?

  I installed ESX4.0 and 3 both guest OS.

  but I would like to change the size of the block!

  My shared storage is NetApp.

  I also have a vCenter as a virtual machine.

  Thank you!

  You can change the size of the block of the partitions for your computer virtual guests. When you format a partition in your guest virtual computer, you have the choice to be formatted for example 4K, 32K or 64K. You will want to choose a number so that the partitions are lined up along 128 K. I think that you can choose the 32, 64, or 128 K. This applies to your data since the boot partition partitions have to be aligned.

• data from the buffer before graph it and block size

  I hope you can help me with this situation because I was collapsed in this situation for two days and I think I see the light in the short time and time is a scarce resource.

  I want to use a NI DaqCard-HAVE-16XE-50 (20KS/sec accordig to the specifications). For data acquired by DasyLab, I use OPC DA system but when I try to get a graphic from the signal I get ugly results.

  I guess the problem is that the PC is not powerful to generate a graph in real time, is if there is a block to save the data, then graph the data without using "write data" block to avoid to write data on the disk?

  Another cause of the problem, it might be an incorrect value for adjusting the size of block, but in my piont of view with the 10 kHz and 4096 block size is more than necessary to acquire a signal of 26 [Hz] (showing the photo). If I reduce the size of the block to 1 signal showing in the graph is a constant in the first acquisition value. Why might this situation?

  Thanks in advance for your answers,

  You don't want to use OPC DA for a device installed with the material. OPC DA is designed for industrial devices low speed, not for cards installed 20 kHz!

  Rerun setup of DASYLab and select the OR-DAQ driver, deselect the NOR-DAQmx driver.

  You must use the analog input OR-DAQ module for talking directly to the camera. You will get the full speed of the device, and the buffering is managed properly.

  I have this card somewhere in a box, and when I used it, it worked perfectly with the NOR-DAQ driver.

• 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.

• Block size of a VMFS data store limitations

  I installed my ESXi 5 server with the default block size

  For the moment, I'm trying to convert the Windows Server 2008 and I have the alert message is: "*.vmdk file is larger than the maximum size.
  supported by the data store.

  It is possible to change the size of the block after the installation of ESXI5?

  Please can you help me because I have converter many server and it is not possible to re install my ESXi server.

  Help, please.

  The screenshot I understand you try to make a volume based cloning and you have deselected (i) and selected a share resource (FAT).

  It is possible to deselect the share (in BOLD) resource and give it a try

  Is - this possibe on a disk based cloning an audit?

  Just to be safe, you have enough space on your data store to perform this conversion, and what version of Converter do you use?

• Pointer of RDM / vmfs block size?

  We run ESX 4.0 on Dell R710s connect to a network SAN IBM N-Series on CF.

  This week we had a major outage due to a server RedHat MySQL fall.

  Off firstly the server wouldn't boot past virtual POST-sachant a RDM disk I have it deleted from the configuration. The server would then boot to OS, but every time that the ROW was reconnected it would either fall or unbootable.

  I remembered we had farily recently expanded space on this server and the RDM was now 300 GB in size. However the space used was only 85% on the lun (255GB). Then I remembered the limits of block size. The server was sitting on a partition vmfs with a block size of 1 MB (256GB max). So I removed the RDM and svMotion had the server in a data store that have a block size of 2MB, reconnected the RDM and the server starts very well. After a consistency check DB we were back running.

  This survey of fault, I went to read the document of maximum rates of the white paper

  http://www.VMware.com/PDF/vSphere4/R40/vsp_40_config_max.PDF

  to be honest - had some vague information on RDM

  and then I found VMware KB

  http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1029697

  surprising to me, which clearly states the pointer RDM files are affected by the block vmfs sizes.

  However, there is a difference of opinion in this thread

  http://communities.VMware.com/message/1507498

  And look further in my own environment, we have several production server running with connected RDM which are excessive in size until the limits of said block size.

  I need clarity defined on it because as he sits down we could have several production machines in an unstable state, or I'm just left with no explanation for the disc lock, we witnessed and a power outage that caused a substantial loss of business.

  My understanding is that the LUN cannot be greater than the maximum size supported by the data store on that of RDM file pointer is created.  Pointer RDM file does not need to be stored on the same data store, Setup or other files vmdk files, for example you could have moved the file pointer RDM from a store of data with a larger block and left the vmx file and the data store other files vmdk with a block of 1 MB.

  Are you sure that files of pointer RDM for running virtual machines, you have on data with blocksizes warehouses NOT supporting the LUN size they point?

• Block size and cannot run the snapshot-

  Hello

  I have the following LUNS carved to my windows 2008 r2 SQL box.

  ESX 4.0

  LUN2 - DataUn 4 MB block size - 950 GB

  LUN2 - size - 500 GB of block DataB 4 MB

  LUn3 - records the block size of 1 MB - 200 GB

  When I try to run a backup, veeam, got the following error

  < Unspecified file name > file is larger than the maximum size supported by the data store ' < indeterminate datastore >

  What could be the cause and how to fix it so I can run a backup on this virtual machine. How big a LUN should I create?

• How to increase the block size?

  Community VMWare greetings,

  Recently, I installed ESXi 4.0 on Dell PowerEdge T300 server - within this server, I have two raid arrays - one for the operating system (which is an array of 2 GB) and one for the data (which are a picture of 741 GB).  ESXi installed without problem - when I have connected to the server using vSphere machine already had two warehouses of data (datastore1 and datastore2).

  Unfortunately, datastore1 (741GB Bay) has a block size of 1 MB.  I did some research and found that a block size of 1 MB only supports a 256 GB drive size.  I have a server of 300 GB I need to virtualize, so I would like to increase the size of this block to 2 MB or 4 MB.  How can I do this?

  I'm sorry to say, but you need to remove the data store VMFS move all the data off of him and then recreate the VMFS data with the correct block size store.

• Information about the file journal &amp; block size

  Hello

  I would like to know the log files used to store the performance of ESX host that can be accessed. Also can we have 2 TB of storage with 1 MB block size?

  @Arun

  block size is to see how large the file size, you have .jpg .doc .xls etc and its size is 2 TB, then you have to select the block of 8 MB for the vmfs data store.

  I believe you can create 2 TB datastore with block 1 MB

  If I am mistaken please go back

• SVMotion migration between the block sizes

  Suppose I have a virtual machine with a 300 GB hard drive on a data store with a block size of 2MB. Then, suppose I want to svmotion migrate this VM to the data store with a block size of 1 MB. What will happen? It will produce just a mistake, or he'll screw up the VM?

  I'm under vCenter4 and ESX 3.5 hosts.

  Just because I wanted to see what the error said I did a migration cold of a 300 GB vmdk to a blocksize data store 1 MB.   Strange, quite all the validation came during that successful and then after clicking next (when it starts the copy of the file) it gave me the error concerning the size of the block.   The error went something like this test/test.vmdk file is larger than the maximum size supported by the data store 'data store name ".

• in regards to oracle block size os and monobloc io call!

  Hi all
  
  My db(10gr2) block size is 8 k, and
  the BP is on the file system raw device on an aix machine.
  
  OS block size is 512 KB.
  
  How block is read from disk when a call to io unique oracle occurs?
  Which is current, 8K, or 512K?
  
  If the block size for a single e/s call depends on the size of the bone (512 k) block,
  I think that the os block size need to be tuned for oracle block size (8 k).
  
  If we use the raw device file system, operating system level block size has no meaning?
  
  
  Thanks in advance.
  Best regards.

  Hello
  Please refer to the following oracle doc:

  http://docs.Oracle.com/CD/B28359_01/server.111/b32009/appa_aix.htm

  excerpt from it:

  Setting the database block size

  You can configure the Oracle database block size for a higher flow of input-output. On AIX, you can set the value of the initialization parameter DB_BLOCK_SIZE for between 2 KB and 32 KB, with a default value of 4 KB. If the Oracle database is installed on a journaled file system, then the block size must be a multiple of the block size in file system (4 KB on JFS, 16 K to 1 MB on GPFS). For databases on raw partitions, the Oracle database block size is a multiple of the physical block (512 bytes on AIX) operating system size.

  Thank you and best regards,

• Dealing with the Local Storage block size (vSphere 4)

  I have a pretty basic question / easy I think I know the answer want to but to double check.  I spaced that vSphere 4.0 uses a default size of 1 MB, which began to cause problems with our backup software try to attach block vmdk is greater than 256 GB in size.  I want to continue to use local storage for our assistants of esXpress but to do this I need to have a larger block size to the local vmfs volume...  Question is can I safely delete the local storage (if nothing is done off of it) and add it and increase the block size or is there a way of installing to set greater than 1 MB block size?

  Easy points.  Thank you guys.

  • Kyle

  Remember, by default your COS is installed on local storage, so do not remove.

  I think this article gives you the best solution
