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

... 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.

VMware
VMware, a software company founded in 1998, was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies. VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture. Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.

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.
