Just wanted to say thank you for all of your hard work in making this great plugin. Installing OpenVPN seemed like a daunting task but this made it easy. I managed to get my Macbook and iPhone logged into my unRAID 6v14 server in around 5 minutes ...awesome!

Thanks Weebo User Shares are essential to my workflow, I can't imagine not using them. I'm a commercial photographer IRL and I use unraid as my storage server for photo and video projects, I generate about 2TB of data per year so I just add drives as necessary. I then have a Windows box with CrashPlan installed which automagically takes all of that data and saves it in the cloud. I'm only switching to a new server because I've run out of sata ports and space to put drives in my original server (9x2TB). I'm making the leap to unRAID6, a 4U rack server and 7x4TB drives, I think 24TB should keep me in storage for another couple of years :-)

Small update: When I execute rsync on the new server and pull data from the old server I get a speed boost to just over 100MB/s. I think that running rsync on the old server to push the data was creating some kind of CPU or RAM bottleneck (it's an old AMD x2 CPU with 2GB RAM). The new server is an Intel QuadCore with 16GB RAM, this is the command line I'm executing to pull the datat: rsync -avh --stats --progress --sockopts=SO_SNDBUF=524288,SO_RCVBUF=524288 rsync://oldnas/mnt/user/iso/ /mnt/user/iso I'm sure that there is still room for improvement but breaking the 100MB/s barrier is good enough for my needs.

Yes I've disabled the parity drive, it was ~35MB/s with it enabled. If I stop and start the sync the first ~30 seconds run at around 119MB/s before dropping to 75MB/s, I'm guessing this is the buffers filling up. I can see the destination server's drive light is idling every 4 seconds or so for around 3 seconds. I'm sure there's a way to optimise this further.

I'm sure it has an effect. As always with such tweaks, the question is: what is the best value? Is it already optimal? No I don't think it's optimal. Just working on the basis that I can transfer a file from either of my unRAID servers to my Mac via NFS at >100MB/s, I would expect a server to server rsync to be faster.

This is the rsync command line that I'm using on my unRAID5 server to copy data to my unRAID6b14b server: rsync -avhP --stats --progress --sockopts=SO_SNDBUF=524288,SO_RCVBUF=524288 /mnt/user/public/ rsync://tower/mnt/user/public I'm achieving transfer speeds of around 75MB/s, is that good? I was expecting higher speeds (copying large ISO's / managed GB switch etc). NB: Those sockopts that Weebo suggested made a HUGE difference, literally doubling the transfer speeds.

Thank you WeeboTech, that's incredibly helpful. One question, does rsync work in the same way on user shares? My shares are large and span multiple drives.

Thanks Brit, that's not really an option as I need to keep the old server running until the migration is complete. I'll give rsync a try for a large usershare and then try NFS and CP. I'll report back with the speed of each, hopefully it'll help someone else out in the future.

I had the same issue until I started using NFS instead of SMB/AFP to export my shares. It made a huge difference for me, also file copies from the unRAID server to my Mac increased from 40MB/s to over 100MB/s. To mount an exported share on OSX, from the Finder choose "Go/Connect to Server" then: nfs://tower/mnt/user/sharename e.g. nfs://tower/mnt/user/movies

Hi I have an existing unRAID 5 server with 14TB of data in various users shares. I've just built a new unRAID 6 server and would like to copy the data across by the fastest means possible. So far as I can see my options are either to use rsync or to mount the new server as a share on the old server and use CP to copy the data accross from usershare to usershare. Is that correct or is the there a better/faster way to achieve this? Many thanks, Dan
