Reclaim spcae with PowerCLI - https://kb.vmware.com/s/article/2057513

[tkdreamer2]

Hi,

I am working with vSphere 6 (no upgrade schedulded)

My problem can be resolved with the KB2057513, nonetheless I need to reclaim space in PowerCLI, not with SSH (internal process, cannot explain here)

Do you know how to reclaim space with PowerCLI?

esxcli storage vmfs unmap --volume-label=volume_label|--volume-uuid=volume_uuid --reclaim-unit=number

Regards

Gary

You can do something like this.

$esxName = 'MyEsx'

$datastoreName = 'MyDatastore'

$esxcli = Get-EsxCli -VMHost $esxName -V2

$sParam = @{

    volumelabel = $datastoreName

}

$esxcli.storage.vmfs.unmap.Invoke($sParam)

Thank you. It seems to be okay, unfortunately I have an error message saying " device or resource busy"

I don't have yet the password of the other VMs to check is someone is connecting and working on them.

After that I've personnalized the script like this:

"$esxname= 'my esx'

$esxcli= ' Get-Esxcli -VMhost $esxname - V2

$esxcli.storage.vmfs.unmap.Invoke"

Here's the result:

OverLoadDefinition: {boolean Invoke(Hastable args)}

Can you share a screenshot of the error?

Here it is

You might want to have a look at the last bullet in KB2057513

[tkdreamer2]

I used this: -u|--volume-uuid=volume_uuid

but I have a timeout message...

[LucD]

Sorry, not following.
You didn't use the Get-EsxCli cmdlet?

[tkdreamer2]

I did, but I thought you were suggesting to use the -u option.

I already knew about this KB VMware Knowledge Base , but as I said, I have to do it with PowercLI...

[LucD]

No, I was referring to the last bullet in that KB, the one that starts with 'If the UNMAP operation fails and you see an error...'

To try and find why you get the error

[tkdreamer2]

I read the article but I have to activate the SSH to enter the command "vmkfstools"

Unfortunately, my client doesn't want me to activate the SSH --'

It seems we can not unmap a datastore with PowerCLI in vSphere 6.

Thany you anyway

Hi Lucd,

I am trying below command but it was not freeing up the space on the datastore as I have created  datastore from scaleio.

Did you check all the possible reasons why unmap might not work in the KB I referenced earlier?
