Data store space issue
Posted on 2014-02-16
I am having a space issue on my datastore.
I am running two VM's (VMware host: ESXi 5.1)
This morning I could only start one of my operating systems at a time I was getting the following error.
-Failed to power on VM
-Could not power on VM. No space left on device
-Failed to extend swap file from 0kb to 16384000KB
-SharedArea: Unable to fine 'testSharedAreaPtr' in SHARED_PER_VM_VMX area.
OS1: Server 2011 - Thin Provision - 100GB
OS2: Server 2012 - Thick Provision - 300GB
For some stupid reason I have made one thick and one thin, Yes I am an idiot!
I have fixed the problem for now. By right clicking on each OS in vSphere, click the Resources Tab, then click on Memory and Ticking the Reserve all guest memory tick box.
This has freed up enough space so I can run both VM's but I need to fix my foolish mistake for the long term.
I have over a total of 220GB of space on my datastore which is unused, I don't expect the disk usage to grow more then 10GB every 6 months and even that is higher then expected.
The Thin provisioned OS is getting larger. And only has 20GB of space free.
The Thick Provisioned OS had 200GB free.
So my question is.
How can I adjust the free space on my drives,?
1. reducing the side on Server 2012 (thick provisioned) 200GB free atm
2. increasing the space on Server 2011 (thin provisioned) 20GB free atm
3. Freeing up enough space to run both VM's at once. Do I need to get a certain % of space on my datastore unallocated for my VM's to run smoothly.
All feedback is appreciated.
