Loss of communication while removing a snapshot on ESX4

• Reboot the ESX host as possible while on VM snapshots exist?

  Can you safely do a reboot of a host ESX VM there was on this host which are off (of course), but have a snapshot exists at this time?

  Because we restart some ESX host but you also have to install some Windows updates on the virtual machine on these hosts. Normally, we take a snapshot of the WM, install updates, restart, check if everything is working fine, and then remove the snapshot. But after a reboot the ESX host we also check if the VM have started and are working very well. In this case, it would cost me 2 restart and check for WM

  When I could do the snapshots, installation of updates, power off the virtual machine, reboot the ESX host, turn on the virtual machine, all check and then delete the snapshots, it saves me time. Only thing I don't know and can't find is so it record to make a snapshot is by restarting the EX host and if the snapshot can be deleted after reboot normally.

  Welcome to the community,

  don't worry, a restart of the host is quite VMs, regardless of whether they are active or not snapshots.

• Remove orphaned snapshots of backup failed

  ARCserve backup software is a failure while trying to back up virtual machines and leaving behind the clichés that are deleted. I work with CA (ARCserve) to solve backup problems.

  I have a few virtual machines in need of consolidation and others who don't. Can I just do a "remove all" snapshots on these virtual machines or do I consolidate those in need, first of all?

  Thanks in advance.

  Hi Jim,.

  Both delete and consolidate would eliminate them the snapshots, IE do it connects and validate data on the basic disk (VMDK). I'd rather have the virtual machine under tension, then go with consolidation,

  Since we can not estimate on when it can be completed.

  Thank you

• Recommended method to remove a snapshot of the VM?

  Recently, I tried to remove a snapshot of a virtual computer Manager of VM snapshots.  The virtual machine was 80GB in size with an existing snapshot of 50 GB, I gracefully shutdown the OS/VM before you remove the snapshot.  Once I started the withdrawal, all was well until we arrived at 95% (the number 95/99% we all know).  After some research, I decided to cancel the process and restart management via the host services.  This solves the problem and the snapshot appeared to remove.

  A few days later, I was working on another task and ended up experience of the 'an internal error has occurred... ". "Details: object reference not set.... error, this has taken a while to correct but has finally been resolved.  It showed me I thought the snapshot previously removed, not actually are deleted;  I have now lost confidence in the VMware Snapshot Manager!

  As I have to go through the process of elimination of many VM snapshots, in the coming weeks.

  I want to avoid having to experience this kind of problem again, I want to make sure that the snapshot of the virtual machine is deleted and as fast as possible.

  Is there a better way to go through the snapshot deletion process?  Perhaps via the CLI or a tool/utility VMware or third?

  Is there a "verification process" that can be taken to ensure that the snapshot has been actually deleted?  It seems that I can't trust GUI/vSphere Client when it comes to check the instant withdrawal.

  Look at the Snapshot Manager is a reliable reference point in environments with fast, healthy and instant storage infrastructure that does not grow very large (50 GB is very large).

  As a.p., VMware snapshot handling is super reliable, so don't panic when the Snapshot Manager does not display what you expect.  ESXi is very strong in keeping your data via instant recovery logs.

  To answer your questions:

  "Is there a preferred way to go through the snapshot deletion process?  Perhaps via the CLI or a tool/utility VMware or third? »

  -The first step is to prevent snapshots more and more very large sizes and keep sufficient free space on your data for overhead warehouse operational.  Insofar as the preferred method, continue to use Snapshot Manager.  If you think that the virtual machine still works from a snapshot, you can see these files in the data store Navigator.  In the past, we had to use the CLI of ESXi to merge and clean up the trees in the snapshot safely.  VMware has introduced a version of this method in 5.x GUI.  It is called "Consolidation".  See this excellent KB article:

  VMware KB: Consolidation of snapshots in vSphere 5.x

  "Is there a"verification process "that can be taken to ensure that the snapshot has been actually deleted?  It seems that I can't trust GUI/vSphere Client when it comes to check the instant withdrawal. "

  Manager of snapshots and the field "A need for Consolidation" are your first indication.  Understand the snapshot files stored with the virtual machine will give you a greater level of comfort with the internal components.  I recommend this article:

• Help! Remove the snapshot

  Hello

  It is an Exchange virtual server. Someone on my team tried to take a snapshot, while it is online, and it has not been successful. It was to ask him something like do not include "memory of the Virtual Machine. He did and the snapshot was created. Now, when I look at the files on the storage directory, I'm confused. I do not understand why the vmsn file is so small and why there are three vmdk files (I have only two hard drives on this machine).

  This machine has two readers. A single system (drive C) and data (drive E). C is a virtual disk, while E is a Raw mapped LUNS ("Compatibility Mode: / persistent virtual /Independent"). It's time to remove the snapshot, but I'm not confident enough on that. Please see the picture I have attached. I need someone to clarify what these files and suggest a safe way to remove the snapshot. I can't afford much time for this critical server.

  Much appreciated,

  Eagleh

  Hello

  The suggested method for sure is to delete all the snapshots of the graphical user interface, as it has already been answered. The files that you see are the following:

  Exchange.VMDK - 1 volume logic, there is actually a hidden or both files which does not appear in the data store Navigator. Its called something like Exchange - flat hard

  2nd Exchange_1.VMDK logical volume. In this case, a pointer to a RDM and a hidden file which is the delta of the snapshot (Redo Log). This only works if the RDM is in compatibility from snapshot mode.

  Exchange - 000001.vmdk 1 logical volume delta file.

  images of memory *. VMSN VM in this case, it is small because the 1try failed, and the second was set to ignore the capture of memory.

  Hope that helps.

  Kind regards

• Unable to start the virtual machine after failing to remove the snapshot

  Recently, I tried to delete a snapshot on a Windows XP virtual machine in VMware server 2.0. After a few minutes, the operation has failed, then the GUI crashed. I was not able to manage one of my virtual machines until I rebooted the server. My other virtual machines still work fine. I can't just run the virtual machine on which I tried to remove the snapshot. This virtual machine is very important to me and I would try to get it back. Does anyone have advice? Also, I upgraded this version of VMware server 1.x to 2.x, so please let me know if this may have something to do with this problem. Thanks in advance.

  An additional note. If the virtual machine starts, I suggest that you run chkdsk, just to make sure that there are no problems with the file system of the client.

• "Remove all" snapshots causing startup problems.  How to manually compile snapshots?

  Hey guys,.

  We run our production and test servers ESXi 3.5 with great success.  However, like many others, we have struggling to find a good economic backup solution if we use a Perl script edited by for this.  The script applies a snapshot and then copying the original files for the guests.  In the end, the script removes the snapshot, and we're back in business.  Most of the time, everything works perfectly.  This morning, we arrived to find the extremely slow server with about 10 snapshots.  Not realizing exactly what "remove all" done in terms of balooning, the size of the previous snapshots, we chose this selection.  The Server shut down (I guess due to the increase in the size of the previous snapshots) and when we tried to restart, we encountered the error that you see in the attachment.

  Look a bit more close to the data store, it seems that most of the snapshots for virtual disk 1 have been removed, but it has been left over.  The other virtual disks 2-4 were intact.  The server does not start and if I return to the .vmdks that are available, I've lost two weeks of a data value.  Is it possible to manually apply the changes in snapshots to the .vmdks so that we can keep as many changes as possible on the 2-4 drives?

  Thank you

  Seth

  OK - now I would use vmkfstools to each of the 4 drives clone.

  the first is NOMADSERV01_1 - 000009.vmdk

   vmkfstools -i NOMADSERV01_1-000009.vmdk /nomadserv-disk1.vmdk
  

  next is "NOMADSERV01_2 - 000009.vmdk".

    vmkfstools -i NOMADSERV01_2-000009.vmdk /nomadserv-disk2.vmdk
  

  before you try, you must correct the snapshot of the string that was spoiled by the basediskalone running.

  I think that the first two should work if you use the edited files, I have attached.

  Then, two coming soon

• Need help: cannot remove the snapshot - score 98% full

  I have a VM ~ 25GB that runs on my first VMWare Server for about a year. It's in a 30 GB partition, but at some point, a snapshot is created. I don't remember this, but I must have. I can't merge the snapshot using VMWare infrastructure Web Access; the option is not available. I don't see the snapshots by looking at the directory via SSH consle.

  I have another partion available is the same size.

  It is a production server and it seems that I need to deal with that immediately.

  I would like to apprecte suggestions or references to helop to solve me this problem.

  -Thank you,

  John

  removal of files inside the guest is contra-productive - it will enlarge only snapshots.

  Hmm - so you say version 2.0.2 also has this bug?

  So either copy the VM is much more big disk and use the shortcut function to remove a snapshot - or copy it to USB and plug this drive into a host Workstation with installed.

  Or - this would work as well with VMserver2...

  Add a second disk of the virtual machine - nominal size just a little more grand, then one you have now - in a Knoppix live CD boot and

  If DD \u003d/dev/sda of = / dev/sdb

  When the sda is the original disc and the DSP is the new

• How to remove the snapshot works

  Hello

  I have a VM with snapshot 1 and it is the parent of the current state of the virtual machine. Then I caught a few updates, snapshot 2 and it becomes the parent of the current state of the virtual machine.

  1. If I return my VM to snapshot 1 and remove the 2 snapshot will be the 2A merged with snapshot 1 snapshot. Because I read somewhere "if we choose to delete a single snapshot, then just this snapshot is merged into its parent Preview"

  2. what happens if I delete the snapshot 2 without going back to the VM to the snapshot 1.

  
  

  Thanks and greetings

  J.P. Raynaud
  

  Welcome to the community,

  the wording is the kind of confusion. If you "delete" a snapshot, its content is merged into its direct parent. If you go back to a snapshot, all changes will be discarded but the snapshot will still be visible but the snapshot file is essentially empty, when you delete this snapshot after returning to it, so there's nothing that can / will be merged with its parent company.

• Loss of communications with USB-6008

  I have a USB-6008 be used to control a couple of valves with its digital output channels. The digital output channels are a relay that energizes the solenoid valves (valves are 115VAC) switching. The USB device is connected to a USB port on laptop.

  The software/hardware was working fine, then some time while it was connected there was a power surge. There was a 2 a fuse on the 115 VAC line that blew.

  After this communication surge was no longer able to be implemented with the box USB-6008. Is it possible for a power surge affecting the USB device, even if his power comes from the power supply of 5V USB?

  Things I checked so far.

  Restart the computer with the USB unplugged and start back up - no connection

  Check the Device Manager for the USB device to be present - not visible in the Device Manager

  Check MAX for device - does not present as gift

  Check the wiring to the son of course drop - no defeated cables

  try on different laptops - connection

  Connect other USB devices to the laptop USB - another fine feature of devices USB slot

  Check the + 5V channel on the USB device and do not read a voltage

  Any indication seems to be that, somehow, the USB device has been damaged during this surge? Is there some kind of diagnosis offline, I do without seeing the unit online?

  Hello the plough,

  It looks like the surge caused a sort of feedback of the valve of your USB device. This USB device is not designed for industrial applications and can easily be damaged in the situation you described. For a USB device with a greater ability to withstand this type of power surge, you should watch the box USB-6525. A better solution would be a CompactDAQ or CompactRIO system with a NI 9401, which is designed to withstand 1 000 V_rms, verified by a 5 s dielectric withstand test.

• Remove PS snapshots automatically - how?

  Hi, I have a three node Hyper-V 2012 cluster connected to a SAN, iSCSI, a PS6210XV network.

  I am currently back up virtual machines using Microsoft DPM 2012, using EQL hw provider.

  Backups are running fine and fast, but whenever the DPM runs a backup, the PS generates a snapshot of SAN of the volume that contains the vm. When the backup finishes, however, the snapshot is not deleted, but stay on the line until someone deletes it.

  How can I have my snapshots automatically deleted after a backup operation?

  I don't want to use the Hyper-V software provider to make my backups.

  Thanks :).

  You have installed the latest HIT kit, version 4.7?    Looks like you are running fw v7.x EQL?   A change in behavior of the snapshot was introduced at the request of the customer.  If a snapshot is online, do not remove it w/o first put it in offline mode.  V4.7 HIT a code to make it when a delete VSS snapshot is requested.

• Confirm: Have 4 snapshots; to remove average snapshots 2, leaving the first and last

  I thought I knew this, but confused me after having looked further. ESXi 5.5 U2. I have a virtual machine that has 4 pictures:

  2015 12-30

  2016 01-04

  2016 01-05-morning

  2016 01-05-night (latest snapshot)

  I like to keep the snapshot from 2015-12-30 and the last 2016-01-05-night. Do not the other 2; We won't be going back to these snapshots, but you may have to return to the State from 30-12-2015 or 2016-01-05-evening.

  So I can just delete 2 snapshots medium, correct? And yet still be able to return to the State from 30-12-2015 or 2016-01-05-night, if necessary?

  But regardless of what order that I remove them? Can I just remove the sequentially (i.e. delete 2016-01-04 and then 2016-01-05-morning)?

  Sorry if this seems to be a newbie question, but I never deleted a few shots, leaving others like this. I've removed all the or just deleted the most recent; I never deleted snapshots in the middle of a sequence like this before.

  Screenshot of snapshots attached.

  Well, let me explain how...

  Created virtual MACHINE Original.vmdk

  2015-12-30 snapshot created.  00001.VMDK - original created for changes.

  2016 01-04 created snapshot.  00002.VMDK - original created for changes.

  2016 01-05-morning snapshot created.  origianl - created 00003.vmdk for the changes.

  2016 01-05-night snapshot created.  00004.VMDK - original created for changes.

  When you remove 04-01-2016 and 2016-01-05-morning snapshots, these changes are rolled in the original - 00004.vmdk, so if return you to this snapshot, it contains everything, instead of having data access between 3 different VMDK.

  That explain better?

• Consolidate the Snap Shot or remove the snapshot, which should not

  Dear Experts,

  We have a Linux virtual machine, and we recently increased its vmdk to add more than 10 GB but before doing so, we took a snapshot of State off the machine. Increase now the space is done and now if I see the drive for this machine, it shows me 'thick' 35GB

  It is the only snap shot we have for this machine. If I click with the right button on computer and go the snapshot > I see here snapshot manager, take a snapshot, back to the snapshot current and last is to consolidate.

  If I go to the Snapshot Manager, I see the point where I am now and the last point that is marked as 'before you increase the space', so I need to click on consolidate OR click the old cliché and delete to maintain the current state of the machine? How the two are different consolidate and remove all?

  If the disk is thick, I can still get rid of snapshots? Please see attached images

  Thank you and waiting for response.

  So what I understand now is the consolidation option should be used when on condition is true:

  operation "snapshot disks compress after delete or clear all ', other wise I should go for delete snapshot in normal condition, please correct me if I got hurt?

  Peacebuilding operation removes all your recovery logs 'redundant '. But removing any operation remove your shots and consolidate on a single disc.

  Consolidation will cause no change in the number of snapshots. But delete / delete all will remove them actually snapshots and the present changes in this snapshot will be written back to the parent disk. And also always remove snapshot operation was launched with a peacebuilding operation.

  Let me know if you need additional information here.

  Delta records are created whenever a snapshot is taken?

  Yes.

  I have a vcenter Server virtual and it have a snapshot that we created when we start building the vcenter, can I remove it so that I am connected to vcenter server using Vsphere client.

  Yes you can delete it. But since its vCenter, please ensure that you have enough space available in your data store to perform a snapshot of deletion operation. The required space are perfectly explained by Duncan Epping in his blog...

• Cannot remove orphaned snapshots

  One of the servers ESXi 4.1 in my care ran out of disk space today.  This problem has been resolved.  One of the causes is some old shots that take up to 70G (000002,000003,000006 files).  I don't see that they are used.  It seems that the virtual machine has been removed and readded by using the same VMDK. because it's using 2 different directories.  I don't think that this is part of the problem.  The user interface shows no snapshots.

  I tried flushing of invisible snapshots by taking a snapshot and deleting everything in the UI.  Snapshots are still there.  When he creates a snapshot, it uses 000001 and 000004.  The old clichés have not been affected at least 4-5 months, looking at the dates.  I tried to delete them in the user interface, but she came back with an error.

  I watched the vmx file.  He referred 000006 as reader of scsi0:1, but it is not enabled.  SCSI0:0 is the only player.  I thought that if I emptied the 000006 in the vmx file, I might be able to remove it.  So, I created a scsi0:1 disk and then deleted.  000006 is not referenced in the file any more, but it did not help.

  I looked at the latest vmware.log, I don't see reference to files, 2,3,6.

  How can I make sure that they are not used?  And how do I get rid of these files?

  This particular server account local storage, vmotion is not an option.

  I have attached the logs and vmx files.

  Thank you

  Wayne

  If you are sure that the snapshots are no longer needed, but do not want to delete the files immediately, I recommend you properly stop the virtual machine, and then create a new subdirectory in the folder of the VM data store and move the "orphans" files in this folder. Then turn on the virtual machine again, and once you can confirm that everything works as expected, you can delete the subdirectory.
