I need some help troubleshooting or understanding the Datastore Storage View. I had the following situation come up yesterday. My Storage view of my datastores shows all green normal status. each of the datastores shows a healthy percentage of free space - provisioned space is less than capacity.
However, one of my virtual machines stopped and presented a message "there is no more space for virtual disk /vmfs/volumes/{guid}/vmname/vmname.vmdk. You might be able to continue this session by freeing disk space on the relevant volume, and clicking retry."
One question I have is how to find the GUID of my volumes - this VM has three Virtual drives on three seperate datastores (os, data, logs). Each of the vmdks are named the same so without a guid to datastore conversion, I could not determine which virtual drive was the culprit.
On my vcenter datastore view, all datastores were in great shape. As this is a production environment and the server had to come back up, I deleted a server I no longer needed which had a similar drive setup on the same datastores. After which the VM started.
But now I am left with the unsettling reality of not knowing what my actual available space is, and / or what space my VM's are seeing.
Any help or insight into this issue would be appreciated.
