VM disk consolidation

VM disk consolidation

I would like to run disk consolidation for a VM that is powered on and used for production.
I am not sure if this operation of disk consolidation will have any impact on the performance of the VM.
Any idea?

Thank you

Yes, it's likely to get worse, than current performance which will be worse than a VM without a snapshot.

It depends what Service the VM performs, sometimes, e.g. an exchange server can drop Outlook connections whilst Merging Snapshots.

Also depends on many things, size of snapshot, current CPU, Memory assigned to VM, and also datastore type, e.g. RAID, SSD, Flash, SATA, SAS, SCSI, 7k, 10k, 15k etc

If you are concerned on the impact to service, it should be conducted out of core hours if possible.

... but be prepared to have it running for hours, depending on size.

I have run Disk Consolidation and it was quick...
The only thing I guess we need to watch for, is if there is a process that is running that can prevent Disk consolidation to complete successfully..
For instance we have backup that is causing the issues on VMs and , I had to Kill the backup process to do the Disk COnsolidation without any problem.

10 Tips to Protect Your Business from Ransomware

Did you know that ransomware is the most widespread, destructive malware in the world today? It accounts for 39% of all security breaches, with ransomware gangsters projected to make $11.5B in profits from online extortion by 2019.

Could not have been very large, VM not very active, or you have "super fast quantum storage!"

Consolidation, or Snapshot Merging, always completes, what causes the issues are VMware Admins, they "meddle".

and being patient and time....
