Vmware snapshots not consolidating

Quiescing is not necessary for memory snapshots; it is used primarily for backups. If multiple snapshots are taken, Delta disks will be created for each of VM disk of the every snapshot and it can represent the difference between each snapshot.

When you delete the snapshot, The changes between snapshots and the previous disk states are merged and all the data from the delta disk that contains the information about the deleted snapshot is written to the parent VMDK disk.

You can even specify the Date and time to best identify its age.

As of now, Just go with the snapshot without Virtual Machine memory.

If fails with this error: This virtual machine has 255 or more redo logs in a single branch of its snapshot tree. While the virtual machine is still running: /vmfs/volumes/XXXXXXXXX/myvm # mkdir consolidate /vmfs/volumes/XXXXXXXXX/myvm # vmkfstools -e myvm-000254Disk chain is consistent. In general a good resource for manual VMWare disk editing is: this isn't really a "fix" as such, and may not be of use to a production server, when I've been faced with issues like this in the past I find the easiest solution is just to use Vmware converter to v2v the machine, this provides an identical machine with a single vmdk per disk and is done with an agent within the VM, rather than at the hypervisor level, so it isn't aware of snapshots.

The maximum supported limit has been reached, creating new snapshots will not be allowed. /vmfs/volumes/XXXXXXXXX/myvm # vmkfstools -i myvm-000254-d zeroedthick consolidate/.

Let’s take a look at how to create Virtual Machine Snapshot from v Sphere Web Client.

Connect to your v Center server using v Sphere Web Client and Right-click the virtual machine - Take Snapshot Name: Specify the name for the snapshot.

It also allows you to take multiple snapshots to preserve the multiple states of the virtual machine. You just need to select the snapshot which is taken before patching to revert to the particular state of the virtual machine in case any issue happened during the patching.

Name of the snapshot should understandable easily from its name.

Description: Provide a description for this snapshot.

To create new snapshots, please delete old snapshots or consolidate the redo logs. I did not move staff around but just committed few snapshots in the middle to get to more manageable count and then used "Consolidate"... language=en_US&cmd=display KC&external Id=1004545 What I did is the following: Use with caution and do not copy commands blindly. We can do that since actual write activity is only on myvm-000255(The last snapshot of the disk).

Now when I try to consolidate snapshots, instead of failing right away with the 255 or more error, it runs for a while, then an error message shows failed because it could not allocate memory.

VMware Snapshot can be simply created using v Sphere client connected to ESXi host or v Center Server and through v Sphere web client.
