VCB snapshot problem

• VCB Snapshots failing

  I get the error when VCB tries to create a snapshot of one of my virtual machines below.

  Create an instant downturn failed because the snapshot creation operation has timed out for holding off the coast of I/O in the frozen VM

  I reinstalled VMtools without timing and drivers VSS and I still get the same error. I read that renaming the files .vmsd and .vmsn could solve the problem. I don't see a .vmsn file in the data store but I don't see a .vmsd file. Can I rename the .vmsd file while the server is in place or should it be turned off? Is it safe to rename this file?

  Thank you

  As long as you have no instant, while there should be no problem with renaming this file.

• snapshot problem

  One of the VM has several snapshot taken before. Suddenly, the harrdisk is corrupt. I recover VM by using disk recovery software. Some files are corrupt, can not be recovered. He has now broken instant channel number.

  VMSD files are corrupt. But delta disk VMDK flat amd basic disk.

  VMware website and forum, I can recreate VMX file by recreating the new virtual machine and by changing some settings.

  A descptions VMDK file can be recreated using vmfstools according to the official website of VMware.

  Do anyone know if there are methods to recreate the VMSD or VMSN files?

  I also find the document to solve the problem of broken chains instant. Do you know how to commit a snapshot if VM has several snapshots?

  Thank you!

  You are right about the CID/parentCID, these values must be unique. However, according to the log files and the size of the hard files the current order of the snapshot is: 4-> 1-> 3-> 2-> base. I created the file descriptor suitable for (see you attachment). You just need to rename/edit them and replace the "xxxxxx" with real names. Be sure to only use a (not Notepad) editor that is able to edit UNIX files such as line breaks!

  Once you have downloaded the file descriptor, you should be able to create a clone using the:

  vmkfstools-i w2k3_xxxxxx - 000004.vmdk w2k3_xxxxxx_clone.vmdk

  BTW, the .vmsn and the files... - ctk.vmdk can be deleted.

• 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!

• VCB backup problem, fails on a script error.

  Dear all,

  We have VCB to perform backups, and whenever we try to take back below error is generated.

  The environment is vsphere and mixture 3.5. I thought that the VM tools are obsolete, don't know if that could be causing the problem?

  Any help would be appreciated.

• 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/."

• VCB Snapshots

  Someone can easily explain to me the process of snapshot for a full image via VCB backup? I'm a little confused on the explanation there.

  VCB uses VMware Tools to suspend the system of files inside the virtual machine.

  A point in image time to the virtual machine is created in a file called delta?

  Any changes made to the virtual disk during the snapshot are in this delta file?

  When the snapshot is removed, the ESX host consolidates changes made to the Delta for the vmdk file?

  Thank you

  In a full image backup a snapshot is created which in turn creates a vmdk of delta that is running on the client.  While the guest is running on this delta file that the originial vmdk is copied to a location specified in the configuration of your VCB, once this process has been completed the snapshot is deleted and therefore stolen some content of the delta originally vmdk.

• 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.

• VCB snapshot creation failed: Pre custom gel script failed - how to fix?

  On a VM I started getting this error of VCB:

  Error: Another error occurred: failed to create snapshot: gel prior custom script failed.

  I found several other discussions about this, with resolutions of filesystem suspend disabling and reinstalling the VMware Tools.

  The guest is a CentOS 5 VM. He has lots of free space. The LUN has enough free space. I tried to reinstall the VMware tools. I tried to create the script pre-anti-freeze, chmodding to 755, even tried to add a simple script ' exit 0' in so that he actually returned correct status of output. "

  Snapshots fine VM in Virtual Center. I can't turn off the setting to suspend as it is set automatically by Backup Exec and I don't see an option to turn it off. Adding to the config.js appears to have ignored.

  The full command that I use for testing that is generating the error is:

  vc-01 vcbMounter.exe - h u Administrator Pei "mypass" - a uuid:564d7acf-0ecb-d867-8e4f-bbcb1aea6508 - r "C:\TEMP\monitor-22-06-408" t - fullvm m nbd - M 0 f 0

  I have several other CentOS 5 VM that work very well in the VCB.

  Any ideas or other things I can try?

• VDR &amp; VCB Snapshots

  VCB creates a snapshot named BACKUP VCB and VDR creates a snapshot named datarecovery .  When using VCB, if I already have an existing snapshot with the same name as the VCB creates, the creation of the snapshot fails. But VDR is remove the snapshot and creating a new, if she identities already existing snapshot named datarecovery . No explanation for this?

  That is right.  We pictured "datarecovery" as a single word could be quite unique not happen accidentally.  As you mentioned, this may have been a bit naïve.  However, please avoid your shots manually generated names like "datarecovery.

• 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.

• 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.

• Problem of VCB backup domain controllers

  I still do research the issue, it may or may not be true, but I was wondering if anyone had a DC using VCB backup problem. iSCSI connected proxy server.

  fact twice and twice (different days) I could NOT connect on two domain controllers. Event Viewer filled with the error logs related to DNS, ATN, time and many others. Restarting solves the problem.

  Someone at - it experience what that be like this?

  I would always advise against him. AD is a sensitive application and you should recover a domain controller virtual in the same way as a physical domain controller.  Using snapshots - enabed VSS or not, is not supported by MS, and you will have problems.

• VCB to different LUN snapshot

  Hello

  I know that the VCB snapshot can be redirected to a different directory than the default. But it can be on a different LUN, too?

  Thank you.

  Heart of the VM perspective it not there no difference betweend a data store or another kind of aslong the LUN is presented to the virtual machine, you can redirect the snapshot you want to.

• 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.
