• 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.

• After removing all snapshots, cannot access shares

  Recently, I noticed that my SIN was not always full despite regularly delete data to free up space. I discovered that the snapshot took all the space, I consiquently delete all snapshots, but the assosiated folder is now gone. I can see the NAS shows again the data are on the NAS, but I can't seem to access if Windows or page of the interface.

  You would have certainly got a popup that requires typing something to confirm that you wanted to delete the share. It is a protection device against accidental deletion of the shares.

• Invalid comments after deletion of snapshot

  All-

  I came across a bit of trouble.  I was wondering if all you saw this, and if there is a pretty easy fix.

  We have a guest Linux running in ESX 2.5up3 managed by VC 2.5up2.  As a precaution I have instant Linux guest in case something has exploded with the new installation of VMWare tools.  I thought I would go one further and clone the machine.  So I deleted the snapshot.  After the removal of the snapshot, the prompt appears as 'Guestname (invalid)' in the inventory, and I can't handle.  The customer is still up and running, fortunately, but I have to take care of that quickly.

  Someone at - he never encountered this before?

  Thank you-

  Pranger Chad

  I stumbled upon this same question myself.  I was able to fix it by deleting the vm of the inventory and then locate the virtual machine is activated and resave the data store.  The virtual machine appear in valid VC and I was then able to start.

• After deletion of snapshots cannot start

  Hi all,

  I'm new here and I try to do as well as I can...

  I have an ESX 3.5.0 with a virtual machine called 'Inventari', this machine and Ubuntu 9.04 inside and 4 clichés:

  1. After a clean install
  2. After installing apache and mysql
  3. After dev a little bit
  4. daily use

  This morning, I tried to remove the 4 snapshots using "Delete All" option on the Snapshot Manager, but after a while (when I return to VI), I see the virtual machine has stopped with error messages. It restarts with the error:

  Cannot open disk ' / vmfs/volumes/xxxxxxxx/Inventari/Inventari-000001.vmdk' or one of the snapshot disks it depends on.

  Reason: The virtual disk parent has been changed since the child was created

  I read (and reread): http://kb.vmware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1004232 and http://kb.vmware.com/selfservice/microsites/search.do?cmd=displayKC & externalId = 1007969

  But nothing works, I can only start the virtual machine to its original state, losing all changes in the last 3 months (stored in snapshots).

  If you look at the vmdk files, there is something that do not fit...

  Anyone have any ideas?

  Thank you in advance!

  And no.... I don't have backups before you try to remove the snapshot (Yes, CONGRATULATIONS MY SON!)...

  Sorry, but I can't tell you what happened. With hard files you have, I am afraid that the data has not been validated for the removal of the initial snapshot is lost. Instant channel seems ok now and all the delta files are used, but according to the size of these snapshot files, they were just created and do not contain many changes.

• ESXi 3.5 full disk - delete all snapshots

  Hi all

  I have a virtual machine running FreeNAS with discs 5 x 200G, defined as a JBOD.  I was filling up with data backup to rebuild some system, when he hooked up with the "no more space for the snapshot files (that's the jist - I don't remember the exact error message now.

  I did not understand where all my space was gone, but have been on a steep learning curve and understand now on the delta files.  I have in the filesystem via SSH, you can see that there are delta files containing hundreds of concerts.  Snapshot Manager showed no snapshots (nothing to delete).  I saw a recommendation to take a new snapshot and then do a 'delete all '.  I did, and the light of the physical server's hard drive was now two hours, strong.

  Is this normal.  I don't want to be hasty and interrupt something that works as it should, but is it possible that I can confirm that it works and not only in an infinite loop?

  A supplementary question.  To prevent this happining again once, can I change the configuration of the virtual machine and make these independent disks?  I can do that, for an existing virtual machine without losing any data on the disk?

  There is one shot in place? Certainly don't lose your patience and try and stop the validation process.

  You can watch the instant process of deletion/committ by the following command (you need to log in with access console not supported - http://www.virtualizationadmin.com/articles-tutorials/vmware-esx-articles/general/how-to-access-the-vmware-esxi-hidden-console.html )

  Watch "ls - Ghtu-* full-time hard" d

  In your question that prevent from happening in regard to again - yes you can make the persistent independent record. This must be done while the virtual machine is turned off. You won't lose data, which makes change.

• VM (invalid) after deleting a snapshot in VMWare ESXi

  All,

  I if I could delete any snapshot at any time to free up space on my drive, especially when I need one instant more.

  Thus, using the Snapshot Manager, I took a snapshot. Since then, my VM is considered invalid. She is still in progress, but I can't do anything with that (summary is empty, shows considered events null, empty and the console is nothing more than a black window).

  Is it possible for me to get this machine? I was about to make a new snapshot... and I really wouldn't want to see my work as missing.

  Thanks for any help,

  See you soon,.

  OD.

  I just got the phone with support, and in our case, it was the cake.  On the VM host console, vmware-cmd-l showed all the VMS in the inventory except the one in question.  In Virtualcenter, we have removed the server greyed out which was "invalid" inventory, then re-added.  Now all is well and everything seems normal.

• Creative cloud says I am out of space, even after deleting all files from archive

  So earlier today, I ran out of space in the creative clouds. I went to archive and deleted all files (archives are now totally empty).

  I have some files left in the Cloud, but they occupy only 3.18 GB. In any case, the cloud always said I used 100% of my storage space of 20 GB and I get the "out of storage" error message when you try to synchronize new files!

  Hey,.

  So I was legitimately deal with this, but I thought about it.

  Apparently, anything you download is checked and it does not show in your desktop folder.

  If you connect to your cloud to Adobe online, you can go to 'Archived' under 'Files' and delete everything again.

  I don't know if you can disable archiving, but it does not work. I was able to download a * after hours of not being able to file.

  I hope this helps!

• Delete all snapshots for a virtual computer

  Hi all

  Snapshots are deleted a when I execute the command below.

  I need to delete all the snapshots for specific virtual machines on a specific period of time, so I would like the same calendar.

  Get - VM VM1. Remove-Snapshot

  Is it possible to delete all the snapshots at a time, as we have option in vSphere Client.

• Delete all SNAPSHOTS with script

  I'm trying to set up a workflow for my colleagues to easily adjust color, brightness and so on by simply clicking on a SNAPSHOT that easily shows them the result. The snapshot is generated by a macro master calling alarge number of macros. But my clever :-) solution fails because I want to give them the opportunity to run the macro master twice (for example the brightness) and they are then asked with a dialog box that asks them if they would like to replace the snapshot that already exist wit the same name. Simply, I don't know an easy way to delete snapshots. Historic range is easy to remove. If it was just a bunch of macros I could find a way to fix it manually, but I have like 80-100 macros in different groups.

  I thought of this solution:

  MASTER MACRO 1

  -SELECT ALL. COPY.

  -DELETE ALL THE SNAPSHOTS (with the script)

  -PASTE THE IMAGE

  -MACRO RUNS APPLE (Apple instant recording)

  -MACRO RUNS TOMATO (tomato instant recording)

  -CONTINUES DURING SEVERAL OTHER...

  The user chooses instant TOMATO , also wants to run snapshot APPLE. Click again on the MACRO 1.

  Someone out there who can think of a solution or another idea?

  (Photoshop CS6 on a Mac)

  Here is the solution:

  var doc = app.activeDocument;

  HS var = doc.historyStates;

  for (var a = hs.length - 1; a > = 0;--a) {})

  {if(HS[a].) Snapshot)}

  doc.activeHistoryState = [a] hs;

  delHist();

  }

  }

  function delHist() {}

• Delete all snapshots causing server to consume all of the available disk space.

  Hello

  I deleted all the snapshots on one of our servers and as usual, the server is passed to 95% and then sits there until it ends.   This time he ate a 150 GB Bill and is about to release one of my SAN LUNS?  Is this normal!

  In any case what can I do to save the servers, if anything?

  HELP ME PLEASE!

  Thank you

  David

  With multiple snapshots, ESX will first create a new disc in which it will merge snapshots. So depending on the size of the LUN size VMDK, sizes of snapshot, there a sense... Not funny, I know

  Tip: install a script or some tasks or alerts that monitor the use of snapshots. We have a script in place that brings all the older snapshots then 7 days. We do not allow older snapshots then 7 days, if they're going for 7 days, the 'owner' must have a very good reason why he wants to run.

• Cannot open Firefox even after deleting all files and profiles of school boards.

  My computer auto-installé the new Firefox version 40.0.2 (and later 40.0.3) and the browser does not open. It worked and I have not received any error message. I tried every fix I can find here, and even manually, I deleted all of my profiles, folders, program files, uninstalled, reinstalled, restarted my computer, and it still not open. I click on the Firefox button in my bar tasks, the charging symbol goes for a few seconds, then more nothing. Firefox opens and runs without any problems on other computer on computer accounts. I even copied the files of Firefox to the another computer account on which it runs and replaced all files on the computer account that Firefox does not on, rebooted and still nothing. I've been dealing with this issue for over 2 weeks now and am very frustrated because I spent hours trying everything I can find.

  This fix does not work either... tried previously and tried again. However I FINALLY got my Firefox to work on mine. I ended up finding a virus free online (ESET online scanner) scanner and do a full scan on my computer in order to remove anything that could cause a problem. I also went through all my computer programs and documents and cookies and temporary internet files and deleted everything which is not necessary or if it is no longer used. I thought it must be something else because Firefox has no problems with other users of the computer, and my original profile worked very well under other computer users when transferred manually. I think something was interfering with Firefox, which is why none of the fixes here worked because they targeted Firefox itself when it seems that it wasn't the problem.

  Thank you all for your comments!

• Delete all snapshots

  Hello

  I started all avoid the VM snapshot almost 4 hours ago. It rose to 95% at the beginning and stopped so far. After 90 minutes of waiting, I realized that VM has been activated (oops) so I decided to turn it off while the abduction was still used. Virtual computer system turns off but the machine not. I could not have done yet because (I think) instant withdrawal is underway.

  Now, how can I check if the deletion process is still running or that 95% is smth like zomie-process? In fact, this virtual machine is not the one I need, but there are still other virtual machines work so I think that I can not turn all ESX host to break the abduction.

  Quick help appreciated, thanks.

  It is important to remove the snapshot when the virtual machine is turned off or does not matter?

  It doesn't really matter. However, depending on the workload of the virtual machine and the amount of disk space available on the data store, you need to delete snapshots, while the virtual machine is turned off.

  When the virtual machine has a single disk, say 50GB with multiple snapshots, why the data in the file are cut on several files that altogether occupy more than 120 GB, even if snapshots are deleted?

  The virtual machine is divided into several files, files of configuration and data files. Each snapshot will start a new file (actually two).

  In another discussion you mentioned use you ESX 4.0. What version do you use? With Update 2 and newer you won't usually problems to withdraw several snapshots using the "Clear all" button, but with older versions you could easily run out of disk space if the space is already low.
