Snapshot limit

• vRA 6.2 disable Snapshots

  When I select the option button 'none' to create snapshots of the tab actions of a master plan, I always have the option and the ability to create snapshots on an item after that I have available. Everyone knows this? I've seen the same behavior on 2 vRA 6.2 deployments to date.

  Affecting the custom property Snapshot.Limit 0 prevents users to actually instant but the tab is always there that it shouldn't be.

  Can you confirm no high users see always instant? This tab will be there to support businesses group admins and users regardless of whether or not it is enabled (I know, it annoys me too).

• How can I reactivate swipe left/right UX (Safari-like) in every night?

  Hit swiping itself works, but the animation is gone completely. Is there a way to reactivate it? I think that the feature has gone since mid-December. It makes FF so more friendly user, I hope that the disappearance is only temporary (and not caused by the costumes).

  Found the bug where to swipe animation is disabled by default, to turn it on go to about: config
  To enable it set browser.snapshots.limit to '5' (or any other value not zero).

  Reference https://bugzilla.mozilla.org/show_bug.cgi?id=678392#c419

  Please let us know that if this problem, currently it is disabled by default for subtlety.

• How can I limit the amount of memory consumed by snapshots

  Is there a way to limit the amount of storage space that each VM is allowed to use through clichés?  For example-, I create a virtual machine with a 50 GB hard drive, using a provisioning.  Snapshots are taken regularly, until the size of the hard disk of the virtual machine plus size of all of his shots is 100 GB.  Assume that 100 GB is all the storage I want to allow any virtual machine to consume on the SAN.  Can I create a parameter through VMware or a tool of management of open source, which will be shot at 100 GB and prevent the snapshots taken once reached the limit of 100 GB?   I'm looking for a parameter that can be defined once and applied to all virtual machines in the environment.

  Thanks for your comments.

  as far as I know, this is not possible. You can set permission on the question of whether a user has the features of snapshot, but you cannot set a quota, etc. You cannot control the number of snapshots, a user might take or how much it can grow by. A single snapshot can develop up to the initial size of the virtual machine.

  VMware has an interesting poll on the management of the snapshot some time ago and some of the questions can suggest future features that could allow a type of instant control growth, etc. We will have to wait and see, but as it is today, it is not configurable. You can probably write scripts to monitor these virtual machines and after reaching a threshold, you can draw attention to it and maybe disable the snapshot feature but that will not stop a snapshot to give more if there are major changes in delta.

• ESX3.5/VIC: How to limit the number of snapshots?

  Hello

  We use ESX 3.5U4 Starter Edition with Virtual Infrastructure Client.

  Is there a way to limit the number of snapshots to a virtual machine?

  We would like to have a strict limit for particular VM nobody can make more than 2 shots. This means that they must remove the old Snaptshots until they can make new ones.

  Thank you

  Kind regards

  Phil

  As previously reported by Duncan, no, there is no way to limit the number of snapshots. I also confirm that it is the same limit on vSphere.

• EqualLogic snapshot settings

  A few questions.

  I'll take snapshots of about 20 volumes at the same time. Will there be a simultaneous instant time limit? I couldn't find any documentation on it.

  Are there plans to have an option of additional snapshots in the future? When my users create large sets of data, I hate those who have to accumulate.

  Any plan to create instant global settings to choose, especially for snapshot schedules? It seems strange to have to create a new item of schedule for each volume.

  Thank you.

  Tim

  Hello

  You can create a collection for snapshots and the replicaiton will be done at the same time.  Check the notes version of Firmware for the maximum number of volumes, as it is FW and model specific.

  Snapshots are incremental.  All shared pages are not duplicated in the snapshots.

  Re: schedules.  When you name a calendar you can reuse these settings on another time.  The Administrator's guide has info on this.

  Kind regards

• ORA-01555: snapshot too old: number of rollback segments

  Therefore on Oracle 11.2.0.2 on Solaris.  High level, we have a pretty large table on one of our Oracle dev instances, lines 430mil, where the data was populated by a large data load.  Two of our date fields have been left NULL so that we have to go back and update every row after the fact with SYSDATE values (some downstream applications require having some sort of date in this area).

  in any case, I wrote a script for this (truncated a bit for brevity):

  DECLARE
  ...
      ln_limit      NUMBER  := 10000; -- Max amount of records to process in a single bulk update statement    
      lv_total_rows INTEGER := 0;
      lv_count      NUMBER;
      lv_rowid      VARCHAR(18);
    
      CURSOR tco_cursor IS
          SELECT ROWID
          FROM LXRO
          WHERE LxModDate IS NULL;
    
      TYPE t_rows IS TABLE OF ROWID;
      lv_rowids t_rows;
    
  BEGIN
  ...
      OPEN tco_cursor;
      LOOP
    
          FETCH tco_cursor BULK COLLECT INTO lv_rowids LIMIT ln_limit;
        
          FORALL i IN 1 .. lv_rowids.COUNT
              UPDATE LXRO
              SET LxModDate = SYSDATE
              WHERE ROWID = lv_rowids(i);
  
  ...     -- (writes to log table here)          
          COMMIT;
  
          EXIT WHEN lv_rowids.COUNT < ln_limit;    
      END LOOP;
  
      CLOSE tco_cursor;
      COMMIT;
    
      EXCEPTION
      WHEN OTHERS THEN
          dbms_output.put_line(TO_CHAR(lv_rowid) || ' - ' || sqlerrm || ' - ' || TO_CHAR (ln_counter));
  END;
  /
  
  

  Only, the work runs for an hour and updates 37mil lines in a same test, and then gets the following error:

  ORA-01555: snapshot too old: rollback segment number 30 with name ' _SYSSMU30_4136132754$ ' too small

  I did some research on the error and read something interesting:

  Do not look around is committed. In other words, don't fetch on a slider was opened before the last commit, especially if the data surveyed by the slider is changed in the current session.

  Also, if the query is a loop with a commit in it, it can do the same without other queries, because finally the next iteration requires looking at his own first generation, cannot do so and barfs.

  Upping undo_retention may help, or not, as the real cause. See also v$ undostat, you may still have information in there, if it is current (or not, since at the time where you check the necessary info can be gone).

  I think that our UNDO tablspace has 16 GB now.  I do not try to hold back the 400 million lines in temp would be feasible, that's why I am committed all 10 k rows, more we ran into problems of memory with a version non-bulk this script before.  It will only be a time process (we have set our data migration to fill in these fields in future iterations).  Am I better choose to simply keep this job and re - keep on running for hours all the hours given the amount of data?  Is - this naïve to think that I could make this many updates without error in a single task running?

  Simply change the column and set the DEFAULT as SYSDATE clause. Now, you would not have to perform the update at all.

  And for the current issue, a single update could have questioned the size of the CANCELLATION. I guess that's what you're talking like memory problem. Good thing for you to do is to work with your DBA and Set configure your CANCELLATION as a result. If not enough UNDO available then you can split the update in the form of fixed numbers and run them, something like that.

  I used a 10-million limit. But you can work with your DBA and attempt to set even more.

  loop

  Update lxro set lxmoddate = sysdate where lxmoddate has the value null and rownum<=>

  commit;

  When the output sql % rowcount<>

  end;

  /

  Collect bulk copy the data in the PGA (private memory). It is a very expensive operation. Collect bulk was introduced mainly to reduce the change of context. But its performance is mediocre compared to direct SQL. So try to make your work in SQL right front.

• Delete a snapshot

  Hi all

  Our largest VM, there is a residue of a snapshot of Veeam since January. The use of the disc is 1.46 TB. I guess delete this snapshot will take some time and use the heavy disk activity. I will in a Summit out of time.

  My question: is it possible to remove the snapshot while the virtual machine is running and what do you think how long it will take? To disconnect the virtual machine is not really an option, and I'm not sure that the snapshot deletion process would be much faster.

  Thank you

  Edy

  The time limit is proportional to the amount of data that the virtual machine is written during consolidation, if the virtual machine is running. If this virtual machine has very high I/O consolidation then process may stop VM to the last step. This is not mandatory, but depend on the size of VMDK, VM e/s and health/performance of the storage.

  I suggest doing this powered off-State, as you say of vmdk is great. But if you want to power on State, then do it hours when there is not a lot of activity on the data store and VM is less accessible.

• snapshot.maxConsolidateTime

  Hey there.

  I want to add this setting.  By Ko (below).  The "30" is entered on the right side, where you can read "Value", correct?  While ensuring...

  VMware KB: Consolidation in VMware ESXi 5.5.x and ESXi 6.0.x Snapshot fails with the error: maximum consolidate ret...

  You can increase the time limit on the consolidation of snapshots by changing configuration settings.

  To change the Configuration setting to increase the time limit on the consolidation of snapshots:

  1. Shut down the virtual machine.
  2. Right click on the VM, then click change settings.
  3. Click the Options tab.
  4. Under Advanced Options, click general.
  5. Click on Settings of Configuration and add snapshot.maxConsolidateTime = 30.

  fix! It would be something like:

• "Snapshot.Policy.AgeLimit" vCAC 6.2.1 behavior

  I added the Option to a test VM to verify the behavior when the age is expired.

  
  

  I see that detail of the VM website has Information on this subject and the snapshot cannot be restored.

  
  

  Is this expected behavior?

  Yes, I think so. It's documentation:

  1. Snapshot.Policy.AgeLimit - Sets the age limit in days, for snapshots that can be applied to machines. When a snapshot is beyond the age limit, apply the option is no longer available. When the snapshot age limit is reached, the image remains, but you can return is more to it.  You can remove the snapshot by using the vSphere client.

• Prevention of Snapshots

  How can I prevent anyone, anywhere to take a snapshot of a given virtual machine, regardless of their permissions in vCenter?  What I should use on that role permissions, or can it be defined in the .vmx file or in another way?

  Thank you!

  You can use the snapshot.maxSnapshots on a virtual machine setting to disable snapshots to take:

• How to stop vSphere to make snapshots?

  Hello!

  I have a big problem (for me it's a big - it's probably a little for you guys). One of my former colleagues had configured our VMS to take a snapshot of one of our virtual machines each week. Unfortunately, snapshots are really big and the process is really slow machines.

  Now my problem: I tried to stop the snapshot job. Unfortunately I can not find where he started the task to generate.

  I already looked at the virtual machine, but the Snapshot Manager showed old clichés and all I could do is delete. Could you please help me? Where can I remove task that forces the generation of snapshots

  We use vSphere 5.0.

  Thank you very much!

  With sincere friendships.

• Workflow slow when you take snapshots

  I have a question about the connections of vCenter.

  Is there a limit on the maximum number of requests can be sent per second for an individual to vCenter connection?

  The reason why I ask is that we have a 'problem' with Orchestrator.

  We created a workflow check if it is possible to create a snapshot (enough storage, has no snapshot,...) and it works for 1-2 seconds.

  But when we begin to create Snapshot (default Orchestrator workflow), and while the snapshot is being created we run the same validate workflow (see above) then this runs workflows for 8 to 10 seconds (factor 4-5 slower)

  And we put the finger on the question of the "vim3WaitTaskEnd" in the instant of creation. If the vote is set to 2 seconds (by default), we have these problems. If we increase the terms of the poll to 300 seconds (to remove it), we have no more of these issues.

  While the snapshot is created, we run the same snapshot to validate, but as a different user, then she extends over only 1-2 seconds again.

  So there must be some sort of maximum number of orders per session/connection?

  
  

  Or y at - it a solution for this?

  The upgrade to version 5.5.1 fixes

• Maximum number of snapshots

  Is there a limit on the number of times that an image can be the snap-snap-shotted or is it dependent on only the disk space?

  Please look at tak KB VMware: best practices for snapshots of virtual machine in VMware environment which explains the limits and instant effects.

• How to create an effective script that mass deletes snapshots

  our company is currently using a product that drives the operating system and software updates for our virtual machines and takes a snapshot before pushing updates in case something breaks. the problem is that the same software does not remove the pictures until next update button and you're just too long we wait with snapshots lying around. what I did to remedy this situation is I built the below script and configured it as a task.

  # Add the snap-snap powercli in
  Add-PSSnapin VMware.VimAutomation.Core

  # Connect to an instance of vCenter
  $strviserver = "vCenterServer".
  SE connect-VIServer $strviserver

  # Get all of the snapshots for each virtual machine in the vcenter, then delete them
  Get - VM | Get-Snapshot - name "updates" | Remove-Snapshot - confirm: $false

  # Remove the snap-snap powercli in
  Remove-PSSnapin VMware.VimAutomation.Core

  It works, but it is not nearly as effective as I wish it were. Essentially, the script currently removes a snapshot at a time right now. I want so he can find any snapshot on this server vcenter by the same specified name and submit the task deletion-Snapshot for each snapshot at the same time. This should cause a lot of tasks to try and tail. The effective result would be that vCenter will treat all instant destruction because it has resources to do in a given time and will address the queue there resources.  If someone can tell me how to do this or something better, I would really appreciate it! Thanks in advance!

  You can consider using the RunAsync switch on the cmdlet Remove-Snapshot .

  In this way, that the script will continue while delete the snapshot is still running.

  Note that there is obviously that a limit on how many parallel snapshot removes that may occur due to the resources available.
