Can't reclaim space when it's hpe simplivity thin provisioning?

[Jh9]

SVT node has a 20% disk space warning, so I cleaned up the files in the guest OS.
The capacity is empty within the OS, but the VM does not reclaim it and remains the same. The Simplicity datastore does not appear to support unmap..

Is there only a way to retrieve it with sdelete tools within Guest OS, how did everyone else solve it?
Please understand that I wrote it with a translator. Thank you.

Hi Jh9
You have already tried deleting files from the guest OS, but the HPE SimpliVity node's disk space has not been reclaimed.

If the datastore does not support unmap, then using sdelete within the guest OS is one option to free up disk space. Another option could be to migrate the VM to another datastore with more available space if that is feasible.

To answer your question about how others have solved this issue, it would depend on the specific circumstances and configuration of their environment. However, using sdelete within the guest OS is a common solution for freeing up disk space on virtual machines.

Hope this helps.!!

Mahesh.

Thank you for your answer!
Storage Migration could not proceed because there are currently no other types of datastores.
(Only SVT-DATASTORE1, SVT-DATASTORE2 of the same NFS3 type exist)

I have one more question.
Is it an existing issue that NFS3 datastores in simplicity are unable to reclaim capacity?

Hi,

i (as well others) use sdelete

take a look at these posts

simply inside the windows virtual machine open a command prompt and run :

sdelete 64 -z X:  (where X: is a drive letter)

repeat for all the the vm drives an for all the VM

please pay attention that sdelete put a huge load on the storage, use it on

one windows drive at a time

in the next 24 hours you will see the vmware and infosight statitics updated
