• 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

• cannot expand the c partition in unallocated space

  I have a HP Pavilion dv5224nr laptop running Windows XP.  I've been low on disk space, so I came on this forum to find out how to remove the recovery partition, since I have the recovery CD from HP.  Now that I deleted the partition through disk management, it only allows me to expand the C partition in unallocated space left by removing the partition D.  "Extend partition" is not an option in the menu when I right click.  I also tried going through the "diskpart" command prompt, select the volume and him asking to "extend".  I received a message that it was unable to extend the volume.  How can I recover the 12 GB of space on my C drive?  Thank you.

  I downloaded a free utility called Easeus Partition Master and it worked very well for resizing my partition C.  I also used explores the function to watch the 1 gig unknown partition and it wasn't empty, so I left it alone.  Thanks for your help!

• All gone VMFS Partition tables! on LUN

  Today, we had a 20 TB of data problems and all partition tables VMFS got blownen now. All ESX servers were not able to see the data stores. Everything is back to normal now, but I have a question, not even a VM has stopped working? How is that possible? VMware said eventually they would have all the blue screen, but the LUN was down to 2-4 hours and not even a VM is down, we have more than 300 + VM can someone explain how it worked?   I guess they were running in the memory cache and depending on the amount of data is being written depends on when they started bluescreen? How does it work?  I am pleased, that was the case...

  Hello

  Discover the recovery VMFS partitions for assistance. SMV will stay running because they know where they write on the disc through a caching mechanism. The disk data were not deleted, only the partition table.

• 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.

• Impossible to expand the C partition after the reduction of the DATA Partition

  I dropped my DATA partition to increase the size of my partition Vista (c), but I can't extend C: (as far I understand it) because it is more than a single partition to the right.

  I can reformat the free space and I have another partition, but I would rather extend C:
  Is there a way to do this?

  Also, I wrote my recovery disks, but the DATA partition again should he be there? Also if you do not delete the DATA partition and that do it again you?

  Thanks in advance.

  Hello

  The problem is that your data partition was created after the C partition.

  If you reduce a partition, the free space appears after the shrivelled partition and so you can not add this free space to the other partition of C that is placed behind the partition Data (D).

  The only way to expand the C partition is to delete the partition D and then to add this free space to the C partition, but I wouldn't delete the DATA partition because it has a record of recovery that is necessary to create the Toshiba Recovery DVD

  But if you have already created a Toshiba Recovery DVD then the deletion of the DATA partition is not a serious problem because the Toshiba Recovery disk would format the whole HARD drive and would create 3 new partitions (hidden WinRE partition, partition C system, DATA partition).

• Hard drive to expand the C partition

  Hello

  How to expand the C partition on the hard drive. For the C partition option is grayed out in Disk Management extend it.

  Dell Inspiron 1564, Windows 7.

  Photo of attached disk management.

  For some reason I didn't your answers on your other thread.

  You can only expand in the unpartitioned space on the right of the partition that you extend. You deleted the D: drive, but the space is not the unpartitioned space. Because you can have a maximum of 4 partitions on an MBR disk, the last of them is typically created as an extended Partition, that allows you to create additional logical drives inside. It is a goofy configuration if this is how he got from Dell. You must also delete F:, then delete the Extended Partition. Then you can extend C: you have unpartitioned space where was the Extended Partition.

• The VMFS partitions and ESX in MUV upgrades

  Back in the day when you installed ESX it deems any VMFS partition is priese formatting for you even if you had all your machines on them

  I intend to upgrade ESX 4.0 to 4.1 using AUVS that resembles a simple process.  Anyone know if:

  1. it clears the local VMFS partition?

  2. He wipes SAN VMFS partitions that it finds?

• Convert VMFS partitions/data?

  Hi again!

  IV been playing with Esxi, Hyper-V and Xenserver for some time now. Finally, I decided to go with esxi for my virtualization project but there are 2 questions, I need to get an answer first.

  1. None of my raid cards that I have at the moment are detected by esxi. I read that theres a lack in the nucleus of esxi so that you can't do software raid; is that correct?

  2. I 3xTB drivers where partitions are encrypted with truecrypt, what is the easiest way to convert these VMFS partitions so I can use them in esxi?

  Thanks for your help!

  Hello

  As far as I know, you have two main options:

  (1) create a virtual machine with a normal vdisk (hard) to place the data of truecrypt. Then make a transfer to network on the virtual machine to a system that has access to the unencrypted data. Finally the date of stay to the virtual machine without encryption vdisk

  (2) create a virtual machine and install the truecrypt sotfware. After that add truecrypt disks (perhaps is better to merge all data from a larger drive?) to the esxi machine. The esxi should see the disk (s) connected (s) as LUN SCSI/SATA. Then, create the physical (s) or the discs as raw device mapping (RDM). In my humble VIEW in your scenario is preferable to create RDM in physical mode. Finally using the truecrypt software you should be able to access the encrypted data.

  Here, you can check a few RDM tutorials:

• 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.

• ESXi 3.5 - clean installation, it will wipe existing vmfs partition?

  So let's say I have a U3 3.5i ESXi server is installed on a single table of RAID 5.  I want to do a clean reinstall using U4.  When I installed U3 it parititoned discs automatically, so when I go to install U4 will be it preserve the current vmfs partition or is it delete and then recreate a new?

  The reason I ask this is just in the preparation of a time where a firmware update could possibly fail (do not assume that it will be, just want to have a plan in case something goes wrong).  Just want to be sure I can do a reinstall with/without losing existing virtual machines.  I'm not worried about having to reconfigure everything - not a big deal.

  Thank you!

  You have the ability to clean any vmfs partition, or leave them alone.  It is up to you to destroy the existing, which you do not want if there's vm is here, or leave them alone.

• Problem of recreate VMFS partitions

  Hello.

  I have a SAN disk on which all partitions are defective.

  I need to mount them and copy the data somewhere else.

  I used: KB VMware: Re-create a missing partition of VMFS datastore in VMware vSphere 5.0/5.1/5.5

  It works on one of the score, but all the others, it gives the error:

  So I do the following:

  It gives me the information for all my partitions.

  I take one:

  This seems really odd. Do you have all the partitions on these 4 discs when you first installed ESXi?

  What version of ESXi you originally installed (3.5 or 4.0) in the case where that this system has been upgraded?

  Please after the release of fdisk-lu for all 4 disks in the system.

• Expand the C partition in Windows Server (not not using diskpart)

  Hi Experts,

  I have an of Windows 2003 virtual machine that has a 12 GB C drive only. I need to decompress. I know that we can use diskpart to extend the drive, but the problem is here that the hard disk is divided into two partitions (C and D), because of which even if I increase the size under the ESX, I don't then expand in Windows using diskpart as it is said there are two partitions on the same disk. Someone help me!

  Hello!

  Normally, you will only be able to extend the partition that has free space immediately after it on the drive (and this is where the free space is added when you expand the virtual disk). So, if your disk layout is like this:

  DISC

  (block0 |) Partition1... | Partition2... | Free space.........................................| last block)

  you will only be able to extend Partition2

  This is why it is recommended to create a partition per virtual disk.

  In your case, I'd watch if it is possible to:

  (1) add another virtual disk to the virtual computer and create a partition (say f :)

  (2) move the data from the disk D: (Partition2) the newly created disk (if the existing D: holds a swap file, you need to create a swap file on the new drive, and then delete D: pagefile in computer properties > Advanced tab > performance settings > Advanced tab)

  (3) change the drive letters in the Disk Manager (change the drive letter to D: in a free r: one, for example, then change to your new drive d :) drive letter)

  (4) possibly restart the virtual machine to see if all the services are running as expected

  (5) use of the Disk Manager to delete the Partition2 (after this your vdisk that holds Partition1 should have lots of free space immediately after Partition1 and it is expandable)

  (6) use diskpart, extpart or any other utility to develop the Partition1

  (7) avoid creating multiple partitions on virtual disks in the future

  I hope this helps.

• What expand a VMFS lun beyond 2 TB?

  Hello

  I need some opinions on what happens if you:

  • creates a LUN smaller than 2 TB (say, 1 TB)

  • built a VMFS on him and he put many VM

  • with the virtual machines running, go to the storage array and resizes the logical unit number, making it LARGER than 2 TB

  I know that this is not a smart thing to do and there is no reason to do it, but I want to understand what happens then a strictly tech point of view.

  For what I know about scsi, I guess that the vmfs will continue to work because there is no way to expand it to fill the new size, so he's going to stay within the limit of 2 TB and conntinue to work.

  But is it possible that growth triggers a few changes in the logical unit number so that esx will not longer be able to access the same first to 2, make the unreadable data and cause errors such as corruptions of metadata in the vmfs?

  I need a scsi on this expert opinion!

  Thank you very much for any info and opinions.

  Massi

  And no growth it will not damage your logic unit number. Personally, I don't see why you would want to passing. Creating a secondary LUN and loading with VMFS are much easier.
