Got this error while trying to upload some ISO’s to a datastore ISO folder via a VirtualCenter client.
While looking for causes I found these possibilities:
- Not enough space in the datastore
- Port 901/902 not open between the VI Client to the source of the file (and/or VC Server, could not find if that is also a factor)
- DNS configuration for the host servers
As a possible solution I also found that restarting the VC Server service could help.
