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:

  • The safest method to remove several old snapshots

    I use tool ASM/VE of Equallogic to make shots, but on 1 of my virtual machines, it has not clean properly on the rise and has failed in some shots.  I want to use the safest procedure to remove/commit these clichés.

    A further complication, as evidenced by the screenshots, Snapshot Manager shows that I have 4 snapshots, but when I browse the data store, I see that there are some files in component 19/2 snap who only sees the Snapshot Manager.

    So, should I use the "Remove all" option in the Snapshot Manager, or remove the buttons one at a time, I guess from which individual snap?

    Fine thanks

    Chad

    Hello.

    The safest approach would be to start at the bottom of the list of snapshots and remove them one at a time while working your way to the top of the list.  Using the button remove all potentially consume a lot of disk space.

    Good luck!

  • 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?

  • How can I remove snapshots when the data store is full?

    Hello

    With the help of ESXi 4.0.0 build 171294

    I have a virtual machine with a number of snapshots that became very large (rookie mistake I know). Finally, missed data store.

    Delete all the snapshots of the apparently successful Snapshot Manager but has not not any space free, and watching the VM directory via ssh show the delta files always there.

    I tried following the instructions in http://KB.VMware.com/selfservice/microsites/search.do?cmd=displayKC & externalId = 1007849

    but the I am always left with a complete and all data store the remaining delta files.

    I also tried renaming the file .vmsd and create another snapshot as suggest in this slideshow:

    http://communities.VMware.com/servlet/JiveServlet/download/978799-10548/200704231611490.TSX2007-Top_Support_Issues_-_part2.ppt

    After remove it all the snapshots returned instantly, of course, not doing any consolidation.

    1. Is there an any hope of consolidating these shots?
    2. If this is not possible, there is a way to roll back all the way to the original disk file?
    3. Update the firmware of ESXi at this stage would help?

    Thank you very much

    Alex

    According to the vmdk files, the virtual disk of 250 GB is thin provisioned. Please take a look in the browser of data store to see the current size of the virtual disk. Commit a snapshot to a thin provisioned disk can consume additional disk space (which you do not have).

  • How can I determine the amount of disk space is required to remove a snapshot of peacebuilding assistance, then a fret?

    I have a 27G vm running on Fusion 2.0.1 - the Mac OS X file system has only about 15 G of free space. I want to shrink the vm disk to release ~ 10 of unused space (which was initially to unpack a large SQL Server db that has since been removed in XP), however, I am unable to use tools to decrease because there are snapshots and cannot remove the last snapshot - when I try I get the error: «unable to clean deleted files» : There is not enough space on the file system for the selected operation. »

    I read other associated messages and understand how the snapshot deletion process works (stolen turns into the existing vm before be deleted). I tried a solution of possible workaround I've seen described elsewhere - creation of a new snapshot, and then remove the existing (old) snapshot and try to remove then the new snapshot - however, which results in the same error. If this procedure fails, a snapshot of the 'Consolidation of assistance' is sometimes created.

    I think that error indicates that space is insufficient on the Mac file system, is that correct? The 15G is not enough. If so, is there a simple rule that told me how much free space will be necessary?

    I think it's a darn good reason to buy a bigger hd faster for my Macbook - but thought I would ask first

    Thanks for your help - much appreciated.

    Doug

    It depends on.  IF you have created your virtual disk as a monolith, then you need at least as much free space as the defined maximum size of the virtual drive.  If you created it as a disc of 2 GB-Split, then you need a little more than 2 GB of free space.

    You will not be able to remove the tiles until and unless you uninstall the applications that you are not using, but here, you can try to remove the app from the modern user interface screen. You have just right click on the app and click on detach start. This will move the app to the application screen all.

  • How to remove a Word from the default dictionary of firefox?

    How to remove a Word from the default dictionary of firefox?
    If I wanted to remove the word 'dog' or 'and' for example

    There may be a range of reasons for wanting to do this, including the deletion of the words you use rarely as similar to other common spellings used words for example. "minute" and "Minuet", delete the words that you find personally offensive, or removing words that, because of linguistic or cultural background, you would not consider words at all.

    Note that I'm not asking how to remove my 'dictionary' words, words that I added myself.

    Hello

    I talked to a few people and I think I'm able to help you with this.

    There are two dictionary files, the default that comes with your version of Firefox and personal 'custom' that you create yourself with phrases and words.

    If you want to change the personal;

    1. Copy Subject: support and paste into the address bar.
    2. Next to the profile folder, click the marked File Show
    3. Find the file persdict.dat. Rename a text file, open, modify, re save it as persdict.dat and replace.

    If you want to change the default dictionary, it could be more of a problem and a lot more technique to do. I would recommend that you look at the problem differently and consider filtering of pages based on inappropriate content using Add-ons such as ProCon Latte Content Filter.

    I hope this helps, but if not, please come back here and we can look at another solution for you.

    Here's what I use and recommend: (these are all free and very effective versions.)

    Avast and Prevx proved extremely reliable and compatible with all I have
    launched on them. Microsoft Security Essentials and Prevx have also proven to be very
    reliable and compatible. Use MSE or Avast and Prevx, Prevx 3 but not all.

    Avast Home free - stop any shields is not necessary except leave the file system, Web,.
    Operational network (Script and behavior are also recommended in Ver 6 +).

    Prevx - Home - free

    Windows Firewall

    Windows Defender (is not necessary if you use MSE)

    Protected IE - mode

    IE 8 - SmartScreen filter WE (IE 7 phishing filter)

    I also IE always start with asset if filter InPrivate IE 8.
    (It may temporarily turn off with the little icon to the left of the + bottom
    right of IE)

    Two versions of Avast are available 6.x and 4.8 x

    Avast - home - free - 6.x stop shields you do not use (except files, Web, network, &)
    Shields of behavior) - double click on the icon in the Notification area - real time Orange - click on the
    Shield that you want to stop - STOP. To stop the Orange icon to show an error indicator-
    Click on the Orange icon - top right - settings - click on the status bar - uncheck shields you
    disabled - click OK
    http://www.avast.com/free-antivirus-download

    Avast 4.8 x - home - free - stop shields, you don't need except leaving Standard, Web,.
    and the network running. (Double-click the blue icon - look OK. - upper left - Shields details
    Finish those you don't use).
    http://www.avast.com/free-antivirus-download#TAB4

    Or use Microsoft Security Essentials - free
    http://www.Microsoft.com/Security_Essentials/

    Prevx works well alongside MSE or Avast

    Prevx - home - free small, fast, exceptional protection CLOUD, working with other security
    programs. It is a single scanner, VERY EFFICIENT, if it finds something come back here
    or use Google to see how to remove.
    http://www.prevx.com/   <-->
    http://info.prevx.com/downloadcsi.asp?prevx=Y<-->

    Choice of PCmag editor - Prevx-
    http://www.PCMag.com/Article2/0, 2817,2346862,00.asp

    Also get Malwarebytes - free - use as scanner only. If you ever think malware and that
    would be unusual with Avast and occasional Prevx running with the exception of a low level cookie
    (not much), to UPDATE and then run it as a scanner. I have a lot of scanners and they
    never find anything of note that I started to use this configuration.

  • Missing optical drives after removal and reinstallation of the only power cables.

    I had a problem with my cd - rw (plextor px-5224ta) and dvd - rom not opening not readers.  I opened my case and only disconnected the power cables, leaving cables ribbons connected, so that I can drag players a bit and work with trays to correct.  Once this was accomplished, I reinstalled the screw on their trays and reconnected power cables.  I start and the discs are recognized only in the Setup, nothing in the Manager device or workstation tab 'manage '.  Once XP starts they disappear completely, no yellow exclamation point, no code error 39, etc just disappeared.  I searched through endless forums and this site and tried everything that has been mentioned previously (double check all physical connections, remove case filters in the registry, the thing FixIt from Microsoft).  When none of that worked, I figured that the discs themselves were dead, even if they would be open, close and turn.  I cannibalized another pc with a cd - rw to hitachi and who threw in there without change.  I booted from the cd - rw with no problems, but windows is not yet anything optical displays on my system.  The cd - rw and dvd - rom are configured as IDE primary master and slave, respectively, although I've tried in the secondary without success.  It seems to me that I have completely a software problem.  I think I'm pretty computer savvy but I am down to a reinstall of XP MCE and I wanted to check with the experts, if I had missed something before.  And if it doesn't I'll throw him off the roof :-)
