oliver Posted December 27, 2020 Share Posted December 27, 2020 (edited) I have 38GB in my cache. According to my array stats, data is being written at about 31MB/s. It varies but that's roughly the average. According to this calculator, it should take half an hour or so to move this much data at the rate above. After 2 hours, it's only moved 4 gb. What's the point of a cache drive if mover is this slow? nas-diagnostics-20201227-0859.zip Edited December 27, 2020 by oliver Quote Link to comment
ChatNoir Posted December 27, 2020 Share Posted December 27, 2020 What are the files you are moving ? In general, large files move quickly (full speed) while small files are very slow. If you post your diagnostics in your next post, people can check if there are abnormal things been logged. Quote Link to comment

They are several very large files. I've attached diags to the original post. Quote Link to comment
jay010101 Posted December 31, 2020 Share Posted December 31, 2020 Same thing here. Writes to the cache as full speed (max spinning drive speed reads). Then when I hit the Mover button (below image) I only get 25MB/s. is this normal? the system isn't doing anything else such as a parity check. though the parity drive is active. Quote Link to comment
JorgeB Posted December 31, 2020 Share Posted December 31, 2020 You can enable turbo write for better performance, at the expense of all disks spinning up for writes. Quote Link to comment
jay010101 Posted December 31, 2020 Share Posted December 31, 2020 I've read some more and have a better understanding why this is happening. I looked at the APP for Turbo Write Schedule and that looks interesting. But as the Mover is doing its work at midnight on this might not be an issue for me. Its only when I'm doing an intentional move that it becomes an issue. Thanks for the reply. Jay Quote Link to comment

ajugland Posted July 21, 2022 Share Posted July 21, 2022 (edited) Thanks I started mover, but that will take a week. Is it safe to reboot and tro to move files with unbalance instead? I just wanted to swap out the the 256 GB SSD witg a NVME but it did make a pool. I just hoped it did a mirror and i could remove the old one, but wasnt possible. I just rebooted the array and hoped for the best. Going so much faster with unbalance in turbo write mode Edited July 21, 2022 by ajugland Found a solution Quote Link to comment
ajugland Posted August 25, 2022 Share Posted August 25, 2022 With unbalance it made some of my files corrupted so I cannot trust unbalance for mover moving bitwarden files. Anyone got a fix to really slow mover? LIke 100 kb movement everyt minute only. When its 100 gb it will take years. Quote Link to comment
