Hi
Recently, two of our vms on the same datastore were stopped and threw this error:
There is no more space for virtual disk '/vmfs/volumes/5b0f6e3d-d0431e09dedb/Server_01/Server_01.vmdk'. You might be able to continue this session by freeing disk space on the relevant volume, and clicking Retry. Click Cancel to terminate this session.
VM configs: esxi 6.5, windows server 2012.
The datastore capacity is 2TB, used: 1500GB, allocated 4.5TB (over-allocated).
I did some search and found people got similar issue like on this article (link), which the solution was to delete snapshots to free space on the datastore. However, my case does not have any snapshots for those two servers.
The only possible cause I could think of is that because I've over allocated that datastore. But it doesn't make sense because all VMs on that datastore are thin provisioned, and that datastore still has 600GB free.
Is there anyone has got similar problem and could advise on this? Thanks a lot.
