Import of .ovf and .vmdk files fails when using VMware vSphere 6.7 Update 2. This issue is planned to be fixed by VMware in their upcoming updates. A workaround is available to resolve this issue in the TID 7023863 https://support.microfocus.com/kb/doc.php?id=7023863.
Large installations require shared NFS or CIFS storage for the /vastorage mount point on the Filr server.
If you are using NFS, you must not target the /var mount point or a child directory within it. Doing so will cause /vastorage to fail to mount when the Filr appliance reboots. (See TID 7017379.)
