• VMWare snapshot problem

  I recently upgraded a server, but before that, I took a snapshot of vmware. I waited a few days to make sure that the server has been run correctly after the upgrade. Appearantly, the snapshot has filled the VM disk. I was unable to start. I deleted the snapshot, but who did not free disk space (at least not yet and it has been more than an hour). I could so he can start by reducing the amount of RAM by using the virtual machine was, but I REALLY need the free disk space. How can I get this free disk space faster. Is there something I can manually remove? Thanks for any advice.

  The speed depends on the workload disks and the speed of storage itself. If there is for example a local RAID running on a memory controller cache write-back, this may take a few hours. Anything that helps is to be patient.

  ... and I tried 2 times today

  Once started the process on the ESXi host races and you shouldn't try to start a second time. This could cause problems!

• VMware ESXi 4.1.0 and snapshot problem - no disk space

  Hi all

  We now have a big problem with our free space on the disk. We are using VMware vSphere (vSphere Client ver 4.1.0 and VMware ESXi ver 4.1.0):

  Our vm has 2 HDD (500 GB, 1 TB). Now we have only 20 GB of free disk 1 and several snapshot files. To remove the snapshot, we need more than 20 GB of free space (corect?). What we need to do more free space? We can move snapshot files from the first disk to the second disk?

  

  

  Thanks for any help

  First of all, you can redirect your new snapshot on another store/disk as explained in this article "http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1002929".

  Secondo, you can delete snapshot older and smaller but not all together as explained in this article by Duncan Epping "http://www.yellow-bricks.com/2008/01/07/delete-all-snapshots/."

• Result of Get-Snapshot problem

  Hi all

  I have a problem with a script. I use Get-Snapshot on vCenter, but the result seems wrong.

  The result of the return 20501,03 Mo command but on the LUN, the size is 3671040 + 17408

  My second problem with the command is the location of the snapshot. If the snapshot is not located in the directory of the virtual machine (workingdir is used on the vmx file), the command returns-1.

  The command works well?

  Thank you

  Olivier

  I can confirm that there are indeed some problems with the cmdlet Get-Snapshot.

  Note that the data store Navigator doesn't tell you the full story either.

  It does not show - flat files and - delta you see when the console files or an SSH session.

• Very new to Vmaware take snapshot problems and a break

  Installed windox xp fine takes a snapshot very well now, I installed some printer drivers and when I try to take a picture or take a break I get the below error.
  VMware is running from a laptop pilot with plenty of room on the driver and space allotted.
  Error in taking the snapshot: failed to save the State of the virtual machine. The State of this virtual machine may be registered only on a file system that supports senior 8,133 GB files.
  The underlying file system only supports files up to 2 GB.

  If Yes, consider changing to NTFS

• Snapshoting problem?

  I currently put in place so that they have a secondary virtual disk which them are attached to virtual machines, this drive is on a separate NFS on the primary virtual disks datastore.

  When I take a snapshot of the virtual machine, it creates a new virtual disk on the data store main nfs and makes the secondary virtual disk. The original vmdk file remains on secondary data store. Is this normal? I really don't want to do.

  Thank you

  Rob

  by default, then snapshot will be created in the same folder where the files reside dishes orginal. If don't need to worry about this.

  Snapshot creates a new delta file for each flat vmdk file in the same folder where and keep any data store. But when you delete the snapshot, it engages in the same folder again.

• VCB snapshot problem

  Hello

  We lack ESX 3.5 - U3, VC 2.5 - U3 and VCB 1.5 framework. VCB framework is installed on the server of the VC (physical windows 2003 host). When I'm connected to the VC via the VI client, I right click on my blackberry VM running Windows 2003 32 bit - Standard Edition and don't take a picture of him OK no probs.

  However, when I run the command directory c:\program files\vmware\VCB framework vcbmounter, it tries to create a snapshot, and eventually times out. My VI client, I see the task of "Creating the Flash Virtual Machine" and after 15 minutes, he said "Operation timed out".

  ESX Server hosting the virtual machine then has an alarm indicating "unable to apply settings of DRS resource to host & lt; esx host name & gt;... Operation failed because another task is ongoing." I end up having to shut down the VM, migrate to another ESX host and restart the ESX host with this error, and he returned to the top of.

  This blackberry VM was P2V would use VMware Conveter successfully. I am able to successfully do this vcbmounter on other virtual machines that have been created from scratch eithyer or deployed from templates.

  Any ideas?

  Yes. This is exactly the case.

• Problem with deletion of snapshots

  Hello

  I have a problem with deletion of snapshots for virtual machine running on ESXi 3.5. I had a problem with the lack of free space on the drive where VM is hosted. I managed to free up space and wanted to commit snapshots (delete) to free additional space. Unfortunately, at the time of the withdrawal of clichés that I ran out of space again on this store now I'm stuck with clichés present in the store but not visible in the Snapshot Manager.

  Any suggestions on how I can get rid of these pictures now? All I can think is move VM converter of this virtual machine to a new one.

  Thanks, Marcin

  The reason that you ran out of space is the way a "Delete All" is handled.

  I guess in your case a 'Delete All' may temporarily need up to approximately 115 GB of additional disk space. Troubleshooting VM snapshot problems perfectly describes the process. Take a look at the animation in the "process behind 'Remove all' snapshots '.

  So what you can do is:

  -Free up enough space, create another cliché, and then do a "Delete All".

  -Cold clone or V2V the VM in another data store

  -Recreate the vmsd file based on the instantaneous channel from the header vmdk files and delete the snapshots one by one starting with the first (oldest) snapshot. If you want to try this make sure you fully understand other snapshots that it will end in the corruption of data!

  Due to the size and the possible impacts on the storage I recommend doing this during peak hours and with the virtual machine shut down.

  If you have a different available datastore (~ 300GB), I would recommend cloning. This does not affect the original files in case something goes wrong. If the clone works, you can safely remove the "old" VM and files and migrates the virtual computer is back to datastore original.

• Delete all snapshots completely hosed my server

  I have a server ESXi 5, a 750 GB (698GB or so, is usable) local data store, quad Xeon, and 16 GB of RAM. There are two vm (s) - we're a firewall which takes about 10 GB (20 has been allocated) and the other is an Exchange Server that has 500 GB allocated was almost complete with the exception of about 10 GB. Both have been implemented using thin provisioned disks. There are also approximately 4 or 5 pictures taken of the Exchange virtual machine. Thinking that I had to delete the snapshots before you try to resize the virtual drive of 500 GB, I hit the button Delete button instant everything. All the snapshots have been removed from the list and then I could not start the virtual machine due to the lack of storage. He said that nearly 698 GB has been awarded! Then I deleted the tiny snapshots for virtual firewall machine and was able to boot the virtual machine Exchange. After doing a little housekeeping on the vm changes that I stopped him. Try to solve the delete all snapshots problem, I tried the "consolidate all snapshots' option. After several hours of waiting it failed due to lack of space. So, I thought I would reboot the physical machine to see if that helped. When he returned he showed that TB 1.4 or so, space has been allocated! And I could not start anything. Then I ran down to the server room, installed a 750 GB extra hd and started trying to move the virtual machine to empty disk. Well, who seems to have been an even worse mistake to delete all snapshots. Not only this process fails, but now the new hd (datastore2) is completely filled and the original datastore1 has about 132 GB free. The problem with this is that the virtual machine is now spread over these two data stores. Now, I've added another store of data via nfs (nfsdatastore) that has free 2.6 TB and I'm currently copy the entire contents of datastore2 via the cp command in a terminal (ssh remotely controlled).

  Any help would be greatly appreciated.

  OK, so let's try to clone the virtual disk in the NAS data store. Please follow the steps below and ask if there is something you don't understand or something does not work as expected.

  • Create a new folder on your NAS "UDT-MX09-EPSI" data store
  • from archive attached extracts "UDT MX09 (Exchange EPSI) .vmx" to this new folder
  • move 'UDT MX09 (Exchange EPSI)-000004.vmdk' to "datastore2/UDT-MX09-EPSI" on "datastore1/UDT-MX09-EPSI-2".
  • move 'UDT MX09 (Exchange EPSI)-000005.vmdk' to "datastore2/UDT-MX09-EPSI" on "datastore1/UDT-MX09-EPSI-2".
  • from archive attached extracts "UDT MX09 (Exchange EPSI)-000003.vmdk" "datastore1/UDT-MX09-EPSI-2"replaces the existing file.
  • from the command line run:
    "vmkfstools-i" / vmfs/volumes/datastore1/UDT-MX09-EPSI-2/UDT MX09 (Exchange EPSI)-000004.vmdk "" / vmfs/volumes/nfsdatastore/UDT-MX09-EPSI/UDT MX09 (Exchange EPSI) hard. "

  If cloning is successful, do a right-click the virtual machine in the inventory and select 'Remove inventory', then - using the browser from data store - click with the right button on the .vmx file in the folder of the virtual machine on the NAS data store and select "add to the inventory. When you start the virtual computer you may be asked if you have moved or copied the VM. Make sure you select that "I moved it.

• Cannot snapshot a virtual machine

  We run a virtual machine on one of our ESX (vSphere 4 Standard) host in a taking snapshots problem. We get the lovely 'operation is not allowed in the current state' and that's what keeps us save the machine through Veeam. I see a lot of messages for this error but found no which dealt specifically on taking snapshots suggesting just reboot the box. It is a production server, and I was hoping to avoid that if possible. I was wondering if anyone has any ideas or clues as to what might be wrong.

  Thank you in advance and here is the message from the vSphere client securely reproducible we get immediately after the launch of the snapshot.

  As you have mentioned, an interesting question

  Maybe something was wrong with the virtual machine when reinstalling vCenter. What I would try to do, is to stop the virtual machine, remove the inventory, (do not drive - remove would probably also solve the problem of the snapshot, but certainly not a way you satisfied), remove the ctk file (this serves to changed block tracking and will be recreated when the next backup/snapshot) and then add the virtual machine to inventory again by right-clicking the vmx file. Once that is done, try to set the "Client" virtual CDROM dirve If it works, you may need to reconfigure this machine virtual of Veeam backup too.

• Disks of the virtual machine consolidation is necessary - vCenter 5.1 U1 + ESXi 5.1 + VDP 5.8.0

  Hello

  I am facing problem as many other people do, when snapshot is deleted, the delta files are still there and warning message "consolidation of disks of virtual machines is necessary" is shown on the virtual machine.

  It happened only few but try to find the root cause. He arrived only on virtual machine located on ESXi 5.1 build 799733 which is located in the task of the WTP 5.8.0 backup.

  Is this snapshot problem, a bug in the version of ESXi?

  Unable to find the release notes, where this is documented as bug.

  Thank you

  Finally, I found a reason, therefore, for other users... ESXi 5.1 build 799733 has a bug that is resolved in the update 1 and higher and is connected to the suspended snapshots created by POS, that is why are there so many discs of delta.

  ESXi 5.1 Update 1 Release Notes

  • When the slowdown of snapshot fails the redo logs are not consolidated
    • When you try to take a snapshot of the suspension of a virtual machine, if the snapshot operation fails near the end of its realization, recovery logs created as part of the snapshot are not consolidated. Recovery logs can consume a lot of space to store data.
    • This issue is fixed in this version. If the snapshot suspended operation fails, the redo log files are consolidated.

• Best practices for large virtual disk

  I would add a large virtual disk (16 TB) to use as a backup storage and ideally thin to allow potential available use of, at least initially, a lot of free space.  Headache is the limit of 2 TB for virtual disks in ESXi 5.

  I know that you can extend 2 TB virtual disks in the operating system (win 2008 r2, in this case).  But is it a good idea?  The underlying array is raid 6, so I guess it's safe, but it sounds at least potentially worriesome me on 8 discs.  Not a matter of concern?

  Performance?

  RDM is less flexible and might be impossible (matrix raid is local).

  Anyone have any suggestions on the best practices here?  What would you do?

  I do not recommend the use of the plan span for the file VMDK disks a bad 2 TB and its all parties (several ways that I saw - snapshot problems, corruption etc.)

  Because they are still local drives, you lose flexibility everything that I recommend using RDM.

  A huge ROW for this virtual machine.

  http://blog.davidwarburton.NET/2010/10/25/RDM-mapping-of-local-SATA-storage-for-ESXi/ This departure to configure it.

  As for what I would do, I've done this before and I used RDM, just for 8TB but still.

• Loss of confusion concerning the data on the virtual disk in VMWare

  The evening

  Excuse the amateurism, but I'm looking for help with a problem I have with a virtual machine.

  I created a Virtual Machine with a virtual disk of fixed size for use as a LAMP (in this case, Ubuntu 9.10) development environment. I have used this in the course of nearly a year and have taken quarterly snapshots, or before, I did something stupid to the BONE. So far we five snapshots and a clone that I got a month ago.

  Recently, I created an another VM to install the configuraiton of LIGHT even on Ubuntu 10.04 (I wanted a new installation).  I didn't know it was a bad idea in time, so I created a second disk on the VM 10.04 and mounted the main drive of the virtual machine 9.04. Obviously, 10.04 altered the disc somehow, as I had received the "+ the Ramdisk parent has changed since the child was.

  created. + "error every time I tried to start it.

  After several unsuccessful attempts to try to find a recent clone, I created a new virtual machine and up from 9.04 virtual disk. However, from the start of this virtual machine, I went back to, what I believe to be, the first State of the virtual machine before snapshots. However, it is also possible that I lost the correct VM while trying to find a recent clone (of course, I hope it's a snapshot problem and not a problem of stupidity).

  My question is, is - it possible that the disc that I mounted does not take into account my snapshots?

  See http://sanbarrow.com/vmdk-errors.html#e4 for an explanation of the error and some tips how to fix it.

  If in doubt ask before doing anything more that could "destroy" the disc.

• Problem with the Auto-Snapshot manager after domain change

  Hello

  I have a client with a FailoverCluster Hyper-v and CSV.

  They recently changed their internal domain name, and since then, they have problems connecting to the PS Group in the Auto-snapshot Manager.

  I get an error saying:

  An error occurred processing action: Discovery.
  An exception was thrown by the target of a call.

  I hope someone can point me in the right direction :)

  I suspect that your iSCSI initiator has problems connecting to volumes - and your problem is, in fact, isolated ASM / me.  Check the RUNAS account used on the services of the DSO to ensure that they use the appropriate domain credentials.

• Problems capturing pictures about OS6 - East System.getProperty ("video.snapshot.encodings"); valid?

  Hello

  I hope someone can help with this query.

  I use the code that is very similar to the sample application camerademo to take a photo using the camera. It works properly on devices running OS5. However, on devices running OS6 photo is just an image of white/black.

  I think I followed the problem until the encoding string passed to getSnapshot(). When I switch which must be a valid encoding string (based on the output of System.getProperty ("video.snapshot.encodings")) the captured image is a black screen. However, when I pass null to getSnapshot() it works correctly. I want to avoid using null as the captured image is much more that I need and for reasons of effectiveness, I would like to avoid having to reduce its size after the capture of the photo.

  I tested this on the 9780 Simulator. The corresponding code is included below for reference.

  Thanks in advance!
