Extend VMFS to 4, 1 TB

• Extend VMFS partition alignment vs. partition

  I have a (openfiler) iSCSI storage and a host ESXi (running on its local disk) for testing.

  I tried to create VM customers and together start iSCSI. The problem I have is the alignment of partition and extend VMFS partition.

  What happens:

  If I want to align parititon, I need to go up and format the LUN with the VMFS. Therefore, the VMFS partition size is fixed. I'm able to increase the size of the LUN, but I can't do anything with regard to the size of the partition resizing VMFS.

  Another way is to report the storage for the VM client on raw storage. But this way, I can't align the partition because I can't use fdisk on raw storage on CLI.

  My question is: if I want to run SQL server, for example, and want to align the disk for the storage of data and able to rescale the size, how can I do?

  Thank you.

  I don't know exactly what you're asking, but "growing" a VMFS volume does not resize the partition, it is done by adding one "scope" (another partition) and then ESX (i) of the volume manager puts the two partitions together to make a large volume.

• Cannot extend VMFS datastore

  Mary!

  I have a virtual machine with two partitions. Partition for the system (IDE) and (SCSI) partition for data. The partition of SCSI has there own underlying the LUN on a storage. LUN capacity was 50 GB where the VMFS data store uses almost the full ability of LUN (49, 75GB). So I developed the LUN on the storage of 60 GB and now I want to extend the data on this LUN VMFS store and add a few more GB. But although I can see the raw capacity (60 GB) of the LUN in storage/properties for this VMFS datastore I can't expad the datastore to VMFS himself. When I click on expand I get no device/LUN to use.

  Any suggestions?

  And my main goal is to expand the data store VMFS.

  It's exactly what I got. When you log on to an ESXi host (using the vSphere Client and the root user), you will have the same storage Wizard dialog box as in the screen shot you posted before. After logging in, go to 'Configuration'-> 'Storage', select the datatstore VMFS, you want to develop and run the wizard.

• Impossible to extend VMFS datastore (after extending the LUN)

  Hello people,

  I have a big problem. I extended my unit number logic of my table from 300 to 500 GB. Then my ESX saw it perfectly, 500 GB (vmhba1:2:8).

  I tried to extend the vmfs data store, but this is post the follow-up of errors:

  Configuring the host error: unable to update the disk partition information

  All suggest?...

  Reading Bogacki article posted, it might be a locking issue, which could probably be bypassed with closing down all the VM in this data store. However - as I have said - is not a supported configuration, and I wouldn't use it in a production environment in waat. I know there is a lot of work and downtime in ESX 3.5, but my recommendation is to create a new LUN and migrate the virtual machine.

• Extend VMFS on HP EVA 3000

  Hello!

  I'm under VMware ESXi 3.5 Update 3 on a HP BL20p G4 with an EVA 3000 disk array connected via fibre channel. The current VMFS is 120 GB in size I want to expand to 140 GB.

  I have already extended the virtual disk in the HP StorageWorks Command View and newly available disk space is displayed in the properties of storage VMFS in VMware Infrastructure Client. (See screenshot 1_vmfs_storage_props.jpg)

  The 'Add to extend' Wizard says that 20 GB are available but I am a little nervous right knowledge because the wizard also contains the warning message: "WARNING: the current structure of the disk will be destroyed." All file systems and data will be permanently los"(see screenshot 2_vmfs_add_extend.jpg)

  I thought that it is possible to extend to VMFS without losing any existing data.

  So what it will really do... to extend the VMFS and keep all data or lose whatever it is, that would be really bad.

  Any help will be greatly appreciated!

  Hello

  Lets start with some best parctices, VMware does not recommend have basically two partitions VMFS LUNs even, but in your case after the measure, it will be a Big VMFS lying on two partitions of the same Lun. What you should ideally make is to create a new Lun of desired size on your EVA instead to increase the size of the Lun even and then extend to the newly created Lun VMfs volume.

  In this case also the message says that the new 20 GB of disk space will be formatted in not the original disk, but however I would advice to follow best practices.

  Thank you

• Extend an existing VMFS partition

  Is it possible to increase the size of a VMFS partition without using extensions in ESX 3 U4?  Everything I see in the manual server configuration is to use extensions.

  Adam

  No, 3.5 cannot extend VMFS partition. The only way - create new old size desired, migrate all virtual machines and delete data store.

• vmfs volume online

  Thank you for all your help.

  I have a volume VMFS with 200G and 1 virtual machine running on it, I want to develop by:

  -increase the size of the lun to storage san to 500G

  -extend this VMFS to 300G of vcentre.

  Is it safe to do online extend VMFS when the virtual machine is running?

  The comments on this VMFS VM config:

  -Windows 2008

  - c:\ 30 GB

  - d:\ 160 GB

  After developing the VMFS, I will be the drive D:\ this 160 GB to 300 GB virtual machine, which means that the vmdk file will be 300G.

  My question is that vmdk will growth to 300 GB across the old size vmfs and the new vmfs size 300 GB, questions about this scenario?

  That is, can the vmdk expand the size and use on a VMFS keys expanded?

  Thank you

  Patrick

  Hi Patrick,

  Is it safe to do online extend VMFS when the virtual machine is running?

  No Yes No worries on that.

  After developing the VMFS, I will be the drive D:\ this 160 GB to 300 GB virtual machine, which means that the vmdk file will be 300G.

  My question is that vmdk will growth to 300 GB across the old size vmfs and the new vmfs size 300 GB, questions about this scenario?

  That is, can the vmdk expand the size and use on a VMFS keys expanded?

  After you develop the VMFS, your host will see a single 500 GB data store. If you can develop your vmdk to 300 GB without problem.

  To expand your vmdk, just right click on your vm--> 'Change the setting'--> select your hard drive--> and type the new size. Then, in your guest OS expand your partition.

  Kind regards

• Spans of data warehouses VMFS are "safe" to use in a production environment?

  I asked this question before, but I don't have a clear answer.

  I have a need to present a 8TB LUN to the virtual machine running Win 2008 R2. The LUN this big is necessary to host medical images for archiving of the software publisher. Storage is that Fiber Channel connected Net App FAS2040A. Currently, my options are to use extends or buy a CIFS license.

  So the questions that I have, is there any questions/problems/concerns with multi - extend VMFS volumes?

  Scopes will not help in this case because the 2 TB limitation also applies to virtual disks. Even if you create an extended data store, you must create several virtual disks and concatenate them RAID 0 software in Windows. I don't know the cost of the licenses CIFS and the impact on disk space you need on the Netapp side, but for me, this seems to be the safest way to reach your goal.

• It is possible to expand a vmfs partition?

  Well, here's my problem, I have 2 esx servers, connected to DS3400, people who originally this set up only bought 4 disks and created a raid 5 1.6 to VMFS partition. The guy he filled and I was running out of space.

  So I bought 2 more disks. I added the readers to the controller and added to the raid, creating a bigger raid.

  I returned in vsphere and saw that there was free space and I tried to extend VMFS partition but I couldn't? I thought that I was not supposed to create a new measure.

  In my frustration, I said F and I just created a second logical drive, formatted as VMFS and added and moved some of the VMm on the new 800 GB partition.

  Now, I bought 4 records more than daughter upward the ds3400. I'm trying to add them to the table.

  I need to make the a VM on the origial 1.6 TB of greater. So I don't want to add a third partition, instead of this I would really be able to extend the partition of 1.6 to 3.2 to with new readers, I add.

  Does anyone know how or if I can do this? Its going to take some time to add the new disks and I need the extra space pronto.

  When I'm in the IBM Storage Manager I see

  Unconfigured space 1.2 to (always adding these readers)

  RAID 5 2.8 TB

  -Original DS (1.6 TB)

  -1 (837 GB) second one I did

  -Release the 418GB capacity (one of the 3 new discs add)

  Once I get the other 3 dirves, I'll have another 1.6 to release capacity on the raid. This is where I'm stuck, how to use that to extend the original 1.6 to vmfs.

  Thank you people a bunch.

  It is possible to expand a VMFs partition - but the problem is that you can not access a logical unit number is greater than 2 TB - 512 B and the largest virtual disk is the same 2 TB - 512 according to http://www.vmware.com/pdf/vsphere4/r40/vsp_40_config_max.pdf - using extensions you can create a volume of 64 KB-16 TB per individual LUN stacking

• Expansion vDisks in HP CommandView & ESX you see does not change

  Hi all

  Recently added records and developed a vDisk Optional HP (HP P6300 EVA), but the other storage does not appear in the client vSphere for use.
  Am I missing something here?
  Any input would be greatly appreciated.
  Kind regards
  Nash

  Welcome to the community,

  after resizing the vDisk in CommandView (and in the meantime for him at the end of the expansion), rescan the vmhba in "Configuration"-> "Storage adapters" on your ESXi hosts and then open the properties of the data (on the ESXi server) store and increase/develop its site (i.e. extend VMFS partition).

• 5 - USB or HDD ESXi installation location?

  I intend on creating a stand-alone ESXi server to run several virtual machines.  HP is envisaged for the seller.  There will be no external storage, all storage will be aboard running, probably in raid 10 or maybe 1.

  My quesiton is this: what would be the ideal installation location for ESXi?  Can I install using an internal USB or flash?  Or would it be better to simply install on the internal HDD RAID non-commercialise all storage is in local?  I am currious what those of you would recommend?

  Thank you

  There is a problem with the ESXi on local RAID which has already been mentioned here and in referenced posts:

  If you have the need to increase available disk space by putting more physical disks in the box and expanding your RAID volume then it will become very difficult to the data on the RAID volume if extended VMFS volume you have ESXi installed on it. It is always possible, but requires hacks of ugly command line (see http://kb.vmware.com/kb/2002461).

  On the other side if you have ESXi installed on a device separate (such as a USB key) you can easily develop the VMFS volume in vSphere client GUI.

• I have can´t several extensions to my data store

  Hello

  I extend my logic unit number and I have a new analysis on my ESX´s and I can see the new space, but when I try to add a measure (now I have still 4 degrees), West nothing available for the scope. How can it be posible?

  Thank you

  Hello

  Before going further, please do a good backup...

  Yes, I extend my LUN, then I rescan and can see the new size, but I can´t extend my data store to this space...

  That is right. You can't do that if you add a new partition to the first LUN. You can add a partition with fdisk. Once you add the partition, you can then see that partition and add it as a point and formatting in a VMFS.

  Just extending the LUN does not have as much as you cannot extend VMFS without using extensions with VI3. So using "fdisk" in the CLI to create a new partition using the free space. Once you have the partition of type "fb" you can then use vmkfstools to formatting in a VMFS, and then add it as a measure to the existing VMFS.

  If you are not comfortable with vmkfstools or fdisk. Then I would decline the logic unit number once more to its original size if you can remember it EXACTLY, then create a NEW LUN, and adds the new LUN as a measure. If you do not remember the old EXACT size then look at the ALTERNATE.

  ALTERNATIVELY, you can create a new unit number logic of appropriate size and SVMotion/migrate all content for the new LUN of the former then destroy the old ONE. It really is a much less intrusive method.

• How to extend a drive with createType = "vmfs" and ddb.adapterType = "buslogic".

  Hi VMware experts.

  You need help to solve a problem.

  I sda.vmdk the file next to the vmdk descriptor and the sda flat, the hard file

  Disk DescriptorFile

  version = 1

  Encoding = 'UTF-8 '.

  CID = 1eed866e

  Partition table entries are not in the order of disc

  Can you please how can I resize this disc. Also, I'm confused about the disparity between the hard disk geometry information in the descriptor vmdk file and the output of the fdisk.

  Concerns

  Ivan

  I always used to gparted to expand the vdisk, I don't think that you can recreate the partition as it already of the filesystems on it.  You will have to destroy the current partition and recreate if necessary.  Be very careful because this could result in loss of data.

  Is there a reason you want to recreate rather than simply extend your existing partition?

• Extend 3.46 VMFS greater than 2 TB

  Hello

  We have an environment virtualized with two ESX 4.1.0 (988178) hosts and a (based on the IBM DS3512 SAS) external storage.

  On the external storage, we have a VMFS (version 3.46, block size of 4 MB) of tuberculosis 1.95.

  We have added a 600 GB disk to the DS3512 to extend the LUN to 2.79 to about... LUN expansion, at the storage level, went ok. If we check the properties of the storage card to the adapter connecting to the LUN SAS, we see that it detects the new size (2.79 TB LUN).

  Since the vCenter, we went to one of the ESX 4.0 host, see storage, right clicked on the storage and choose Properties. Is there an active button to "increase...". ». If we click on that we get an error saying message.

  Call 'HostDatastoreSystem.QueryAvailableDisksForVmfs' to object "datasotreSystem-28"in vCenter Server 'SRVVC' failed." --.

  After that, we get an empty window extension so we can continue...

  I guess're missing us something and I ask some advice. We have expanded VMFS before but they were below the limit of 2 TB, and it was pretty easy.

  How to make we can broaden the VMFS to the maximum size of the LUN (2.79 TB).

  Any suggestions?

  Ciao and thanks in advance

  The upgrade of VMFS3 VMFS5 is a matter of seconds and can be done online.

  Before you begin the upgrade, please make sure that all the components (host, storage) are supported (see VMware Compatibility Guide) by the new version, do not run a question in another!

  Basically, the first step is to upgrade the server vCenter Server (ensure interoperability with the hosts to the VMware product interoperability matrix), followed by the ESXi hosts. Once all hosts running ESXi5 you can update the data store (Configuration-> storage) by clicking on the link "upgrade to VMFS5... ». Once improved, you should be able to increase the data store (maximum is of ~ 64TB). In your case, increase the datastore rearrange the LUN of the GPT MBR partition type. I didn't have the chance to try myself yet, so check again all the documents if there is something you need to take care of in this case. I suggest that - although I think it should work perfectly - make sure you have a current backup!

• Cannot extend a VMFS volume

  I have an installation of VMWare Essentials 5 I've updated since version 4.

  Initially, I had 4 300 GB drives in a hardware raid. After the upgrade to version 5, I added 4 additional disks and used the HP software to extend the logical volume to 1.9 TB.

  I am trying to add this new space to my store of VMFS data but am unable to.

  When I select my host in VCenter and go to storage in the Setup tab and then go to devices so I can see my disk is recognized as 1.91 TB.

  It also shows the primary and logical partitions current:

  Primary:

  1 BACK 16-bit < M 4.00 32 MB

  2 BACK 16-bit > = 32 M 4.00 GB

  3 VMFS 833,22 GB

  4 scope 896,00 MB

  Logic:

  1 BACK 16-bit > = 32 M 250.00 MB

  When I go to the store database properties dialog box and click the button increase then I should see the list of available free space.

  This list remains empty and so I can't extend the volume.

  The file system is 5.54 VMFS with a block size of 1 MB.

  Any help would be much appreciated!

  Regarding kind.

  Sorry for the delay, I did a rebuild of my test system these days.

  I have reproduced what you have and was able to successfully complete such VMFS volume that documented in the link I provided (except VMFS partition 3)

  I did install ESXi 4.1 U2 on a 900 GB drive, then upgrade to ESXi 5.0 and increase the size of the disc to 1.9 TB. Then I opened a session SSH, fdisk used to resize/increase the VMFS partition (which btw. is a primary partition with the new additional disk space adjacent to it) and expanded the cultivated partition using vmkfstools.

  If do not already rebuild you the host, please after af fdisk-lu as well as ls/vmfs/devices/disks
