Hi,<br />
<br />
If you had those Datastore full and then deleted the VMs, or whatever was inside, you may beed to reclaim that free space.<br />
<br />
These are two options how to do it:<br />

Hi Luciano,<br />
Can you please elaborate a little.<br />
Do any of this solutions imply that I have to connect via SSH to each ESXi Server in my cluster and run those commands?<br />
<br />
Also My VMware cluster is version 6.0<br />
<br />
Thanks.

Hi Guys,<br />
I have a VMware cluster (3 ESXi Servers) and a vSAN configured using all the storage among these servers.<br />
<br />
When I go to the vSAN Datastore summary usging the vSphere client it shows 8TB of free space.<br />
<br />
But 2 events are happening that got me worried:<br />
<br />
Event 1.<br />
When I tried to extend a virtual hard disk in a VM the following error message happened: &quot;The disk extend operation failed: msg.disklib.NOSPACE&quot; <br />
<br />
Event 2.<br />
In the vSAN Datastore Alarms tab I have the message: &quot;warning: Datastore usage on disk&quot;<br />
<br />
My Questions:<br />
<br />
Why are these events popping up if according to the system I still have 8TB of free space?<br />
<br />
How can I fix this issue?, preferable keeping all the space I have reserved for Virtual Disks on my VMs.<br />
<br />
Thanking you in advance,<br />

vSAN Datastore usage on disk warning

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.

Storage

Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.

Virtualization

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.
