Install Auto Turbo Mode from Apps for it to switch back and forth between turbo mode and non-turbo mode based on # of drives spinning 2 Quote Link to comment

Yes that's exactly what I was thinking. Use cache normally but if it detects i.e. 7 drives spun up, then cache = no and use turbo write. I guess it's me being very picky though, only a few clicks to operate. Quote Link to comment

No effect on cache use except Turbo would improve mover performance. Quote Link to comment

I am reasonably certain that the auto setting has no effect on whether cache will be used. Quote Link to comment
NewDisplayName Posted January 17, 2019 Share Posted January 17, 2019 (edited) Could you add a automatic way of enabling it while mover runs... because i cant use your shedule because i use a script to run it when cache is more then x% full. Also i dont know what to enter at "Disks Allowed To Be Spun Down Before Invoking Turbo Mode:", ive set it to 1. I have one parity, 10 array disks and 2 cache ssds. #!/usr/bin/php <?PHP $moveAt = 80; # Adjust this value to suit. $diskTotal = disk_total_space("/mnt/cache"); $diskFree = disk_free_space("/mnt/cache"); $percent = ($diskTotal - $diskFree) / $diskTotal * 100; if ( $percent > $moveAt ) { exec("/usr/local/sbin/mover"); } ?> Edited January 17, 2019 by nuhll Quote Link to comment
Squid Posted January 17, 2019 Share Posted January 17, 2019 That script was long replaced by the Mover tuning plugin. But sure, I can add that if I remember in a couple of days Quote Link to comment

vayidm Posted October 13, 2019 Share Posted October 13, 2019 This is a great plugin for speeding up writes. However I've found that it always keeps my drives spinning no matter what. I think it's because there's constantly writes to my domains share (using a VM always on) which seems to keep the other disks always on due to reading the data from them as part of the reconstruct write. How do you use this plugin with a VM always running (therefore performing writes all the time). Quote Link to comment

Right I see, I only have a 256GB SSD cache and the domains share is too large to be on there. The appdata and system share fit on it fine. I've been searching for a plugin or a method to keep hot files on the SSD cache and for them to be written back to the array at regular intervals to try and allow me to use this plugin effectively but there currently doesn't seem to be such a thing. I guess I'll have to use the old method for now. Thanks Quote Link to comment

As you have noted it will keep all disks spun up if any array file is updated. Quote Link to comment

Will have to figure a way to keep all reads/writes on a small cache drive then use this. Thanks Quote Link to comment
CarloGaudreault Posted January 5, 2020 Share Posted January 5, 2020 (edited) With a parity disk active (write corrections on), cache off, copying one TB of small files to a share over gigabit ethernet from a USB 3.0 drive I was getting 10-15MB/s... I paused the transfer, selected "Reconstruct Write" under Settings > Disk Settings > Tunable (md_write_method), went to Main > Spin Up disks, and resumed the transfer in Windows. It averages now at 35MB/s. I get the same speed differences from a USB drive directly in Unraid from Krusader. I have many more TB of data to transfer from unassigned SATA disks, this thread saved me a few days of wait! I'll come back to report my findings, thanks to all for sharing.

Zorb Posted March 29, 2021 Share Posted March 29, 2021 On 9/22/2016 at 3:38 AM, RobJ said: Currently, you only have the option to use the old method or the new (currently the Auto option means the old method). But the plan is to add the true Auto option that will use the old method by default, *unless* all of the drives are currently spinning. If the drives are all spinning, then it slips into Turbo. This should be enough for many users. It would normally use the old method, but if you planned a large transfer or a bunch of writes, then you would spin up all of the drives - and enjoy faster writing. Am I correct in assuming this is still on the wishlist of things to implement? given the mention of a plugin in the last page of this thread? Quote Link to comment

KluthR Posted October 26, 2021 Share Posted October 26, 2021 Thought exactly the same as @Zorb! Is it not planned to integrate the real "Auto" handling to that unRAID option? It is still required to use the plugin to enable the real auto-mode?? Quote Link to comment

opentoe Posted April 8, 2022 Share Posted April 8, 2022 I have the TURBO WRITE plugin installed and right now turned on. I also have my disk settings on RECONSTRUCT WRITE. Are they conflicting each other? My server is up 24/7. Is it a good or bad idea to have both these options on? Quote Link to comment
superloopy1 Posted September 13, 2022 Share Posted September 13, 2022 Guys, do i set the number of drives to the max in my array prior to doing a parity check? Parity check takes an age on my system, just looking for ways to speed it up besides buying a whole new setup ;)> Quote Link to comment
