Hello Team,
We are getting issue in one our physical server regarding the datastore storage issue. It’s showing no free space, but actually it’s not like that.
Here is the screenshot of our all VM’s which hosted on Physical server(10.0.102.85). Even the poweroff machine is showing total used space!! It is reflecting NO FREE SPACE but actually our data is not of 8TB, it is much less than that. I feel it may be some storage caching or other caching issue in our server.
Would you please help us to resolve this issue or guide some troubleshooting command.
Thanks
Praveen Kumar
Hello Praveen,
Are you able to show a screen shot of the VM properties for one the VM with unexpected size as well as the screenshot of the diskmanager inside the Windows? That will help to resolve. Thanks.
Sanjeevan.
Sure PFA.
I am attaching vm properties one of our VM which is hosted on our Physical Vmware ESXI server 6.0. We have assigned this VM size 4TB but actual data is only 60-70GB but it's showing in Vspehere center is used whole space 4TB.
I think it's some storage caching issue or something wrong with the Vmware vsphere server.
Please help us to resolve this issue.
That VM shows that it uses a 4TB thick provisioned VMDK - so it also has a 4TB file allocated on the datastore - what your guest says about the actually used size is irrelevant.
Be careful - your VMFS-volume may run out of free space soon - and you should avoid that by all means.
With just 4GB remaining even starting another VM may be impossible already.
Thick disks will occupy entire disk space irrespective of usage, create VM with thin disk provision.
Hello Praveen,
Think disk (VMDK) will occupy all the allocated space initially when created, in your case VMDK will take 4 TB. So, you can create Think disk, it occupies the diskspace as when the VMDK grow.
if VM has not occupied full 4TB, you can do the storage vmotion and convert the disk as thin.
