Create a shared ISO SR - option to pass SMB version

scls19fr

Hello,

I'm trying to create a shared ISO SR with my 10 years old Synology NAS.

Unfortunately I'm getting

SR_BACKEND_FAILURE_222(, Could not mount the directory specified in Device Configuration [opterr=mount error(95): Operation not supported
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)], )

I suspect that given the quite old age of my NAS... I should pass an option for SMB version.
When I used Proxmox VE I was passing smbversion=2.0 (it wasn't working for newer version).

I wonder if it's not related.

Any opinion?

Pinging @ronan-a and @dthenot who will know what's possible or not.

@stormi There is no way to do this currently.
You could add options manually in /opt/xensource/sm/SMBSR.py:getMountOptions by appending the option here to try.
The simple way would add the parameter to all SMB SR though.
And it would be override by a sm update.

@dthenot Sorry, you were asking about a ISO SR.
In this case, it's in /opt/xensource/sm/ISOSR.py:appendCIFSMountOptions.

@dthenot So there's no way to pass settings through the deviceconfig parameter such as what is possible with NFS VM SRs?

@stormi So I looked into the code of the ISOSR and there is a parameter for the version in the device-config.
The parameter is vers but it can only be V1 or V3.
And if it can't connect with V3, it will also try with V1.
