sebstrgg Posted September 29, 2019 Share Posted September 29, 2019 (edited) Hi, I've just purchased a new server with the goal to minimize my homelab footprint and changing up(down?😉) to unraid from zfs. Before I can shut down the old machines I need to migrate all my data libraries. The thing is that I've ran into a few problems as I'm currently migrating my 13TB library to the new machine. -- 1. While transferring my data from my zfs share to my unraid share via smb I max out on approximately 45-55MB/s on large files. I've scoured the web and this forum for different solutions, but can't get better speeds. The smb protocol might be slow, but that's definitely not anywhere close to limits on a modern version of smb. I've also tried changing max protocol setting, trying to transfer over a disk share instead of user share and all to no use. 2. I haven't been able to reliably mount my share via nfs. Nfs have been activated, added on the share as Public and after verifying it via exportfs -v, I have been able to mount it a few times, but every time it succeeded, it timed out shortly after. Most of the times it times out when trying to mount the share. I've tried this on Ubuntu 16.04/18.04 and Debian 9 machines that all currently have working nfs shares mounted. -- The disks in my new server are verified for ~195MB/s read/write speeds. There's nothing wrong with the physical layer, no firewalls in between my vlans limiting specific type of traffic and no port configuration on the switch that may limit throughput. EDIT: I realized that I missed to add that I have downloaded and enabled TurboWrites CA as well. There is NO difference in speed of the transfer with this enabled, nor any difference in the perceived read/write speeds of the array. (Yes, I have verified that it's active) Same Speed limitations occured when I tried with cache drive ON. While migrating I've not assigned a parity drive nor cache as I already have my data safe on my old setup. I just tried to switch around the setup of array to see if it could help out with speeds, but without any luck. Unraid version: latest (6.7.2) Windows 10 version: latest (x64-1903) Unraid server specs: 1x Xeon Gold 5218 128GB DDR4 2400MHz ECC REG ASUS Z11PA-D8 Array for migrating (w/o old disks added): 5x WD 8TB White (WD80EZAZ) - 4x being used for store, 1x for parity 1x Intel 660p 1TB m.2 nvme - for cache Network consisting of: - Cisco 3750G - Pfsense I'll be happy to provide any additional info needed to troubleshoot the problem. Thanks /S Edited September 29, 2019 by sebstrgg Grammar/clarifying Quote Link to comment
