OSX NFS Storage Repository for XenServer

Setting up an iso Storage Repository for my XenServer testbed. CIFS is an option, but after a couple of “SR_BACKEND_FAILURE_222Could not mount the directory specified in Device Configuration” errors, I decided to try NFS, telling myself that CIFS/SMB is an ugly way of connecting unix systems to each other anyway…

OSX supports NFS nicely, and there’s a good nagware GUI available from Breslink.com.

Five minutes later my CIFS share was available over NFS.

I caught the same “SR_BACKEND_FAILURE_222…” connecting from XenServer to the NFS share until I specified “Allow mounting the folder and any subfolders inside” in the share’s advanced options – which may well be where the CIFS sharing attempt failed. XenServer presumably tries to read every subfolder of a Storage Repository as it’s mounted. I’ll test later.

Incidentally, the minimum required security was “System Standard Only”. The only other non-default sharing option was limiting access rights to the local class C subnet.
