Problem

• ''Test Connection' to External Storage is successfully however when trying to 'Enable Live Storage' an error is returnet:

[!] Error saving Live External Storage configuration:

• Error message in messages log is (Monitor -> Tools -> Logs -> Messages log)

CIFS VFS: cifs_mount failed w/return code = -6

Resolution

When the NAS storage is Windows Cluster, the hostname in the MailGate's external storage configuration page, must be the Fully Qualified Domain Name of the cluster, NOT the IP NOR the server short name. WHY:

1. Error code -6 means:

Retrying with upper case share name
mount error(6): No such device or address

2. Windows Cluster response is:

NT Status: STATUS_BAD_NETWORK_NAME (0xc00000cc)

**STATUS_BAD_NETWORK_NAME : The network path cannot be located. This error can occur if the machine name (\\server, for example) is not valid or the network redirector cannot resolve the machine name (using whatever name resolution mechanisms are available).
