Error Message: 3208 - can't read cifs:localhost;vranger@x.x.x.x/vranger/VM_Directory/Savepoint_na (4047930)

Recieving "Error 3208 - Can't read cifs" while doing restore or backup from NAS device based on samba based O/S:

It is possible to copy files/create directories manually from my VRANGER Server to the NAS. During the VRANGER backup the folders get created on the NAS. During backup while refreshing the screen the file size growing. At the point that the backup should complete the file and directories disappear from the NAS and vRanger starts over. It tries twice automatically but fails with the error Error Message: 3208 - can't read cifs

With restore it fails after creating the vM's on the ESX host.

Devices confirmed:

Synology DiskStation, DS1010, RS408-RP Rack Station, RS810+, N7700PRO

vRanger is trying to verify .var file using cygwin on the CIFS share and unix extensions are being used, which breaks communication.

Disable Unix Extensions on the NAS device:

The "Unix Extensions" on most samba based NAS devices, have to be disabled for proper operation of vRanger.

"Due to the fact that the smb.conf file is reset on every reboot please contact the vendor and ask them how to add this line:

"Unix extensions = no"

Note: Please backup your smb.conf file before making any changes

Disclaimer: The following workaround is not approved nor endorsed by Synology. By applying these instructions, you shall do so knowing fully that if things break down (data loss, or inoperable system), no one can be held accountable but yourself. USE AT YOUR OWN RISK

smb.conf can be found at this location on Synology devices: /usr/syno/etc/smb.conf

Change/add these lines in the GLOBAL section:

ufollow symlinks = yes (This is to make samba work with SMB (win xp) clients)

wide symlinks = yes (This is to make samba work with SMB (win xp) clients)

unix extensions = no

Than:

/usr/syno/etc/rc.d/S80samba.sh restart

or restart synology disk station.
