UNRAID Update 2 – ZX-DU99D4 V1.11 X99 Motherboard Dual Xeon E5-2650LV3 with 64GB of Ram

I have the base components of my new UNRAID server. I got a Chinese X99 dual CPU motherboard off eBay, it’s the ZX-DU99D4 V1.11. Which I will be running two Xeon E5-2650LV3 with 64GB of Ram (both used of eBay). This will be a great base system for playing with VMs and dockers etc in UNRAID using the ZX-DU99D4, as well as running backups.

Unraid and BackInTime over SMB

I have recently setup a secondary server using Unraid to run backups (including with BackInTime). (I will do a full post about it at some point.) I will use this server as a BackInTime server for my Linux workstation, and the Time Machine server for my Mac laptops. Getting it working with the Macs was a bit of a pain, but I got there in the end. But today I shall talk about getting it to work with BackInTime, which I think I have now done.

I ran into a problem thar the standard rsync configuration used by BackInTime was not able to copy files that started with an ‘_’ from the workstation over to the smb share on the Unraid server. This was because when rsync made the temporary ‘._*’ file it would fail as smb doesn’t allow that file name. This was a problem because some of the software libraries that I was using for projects have files that start with ‘_’. So the result was that the snapshots were missing those files and completing with errors. Not ideal. The actual number of files that this affects is fairly low and I could probably live with it, but really it would be better if a solution could be found.

The solution

It turned out that the solution was fairly straight forward in the end. I had to disable the vfs objects fruit and streams_xattr for the share. Then it worked perfectly. The problem is that unraid sets those automatically for each share. So I have to manually delete them, and then restart samba each time I reboot the server. Fortunately that will not be very often.

Still, it would be better to find a more permanent solution. I am currently looking for that, and have posted to a couple of forums to see if anyone knows if it is possible to have custom settings for a share that are not overwritten each time the array is started.
