June 28, 201511 yr I ran that tunable script but found the suggested numbers it gave me made the system slower, so I just want to go back to the original disk settings. What sucks I never took a screen shot of the original numbers. Can someone let me know what the disk settings default settings are? md_num_stripes md_sync_window I can probably just throw up another unRaid and see, but a little lazy today.
June 28, 201511 yr Author Just clear all boxes and press Apply, this will revert settings to default. Duh! I kept hitting reset but left the numbers in there. Derrr. Since that script was designed for V5 there's really no sense in using on V6. Yea, it runs but slowed my system up by using their recommended numbers. Thank you.
June 28, 201511 yr Just clear all boxes and press Apply, this will revert settings to default. Worth pointing that enabling the Help via the button at the top right of the unRAID GUI would have pointed this out as well.

I guess people still need to get used to it
June 28, 201511 yr Author If you haven't changed any of your tunable disk settings can you view the disk.cfg file and let me know what your default numbers are? The file disk.cfg is in the config folder. I've been playing around with my settings and want to make sure I'm starting off at the defaults. I have no idea what the settings do, but I know changing them does make a difference (better or worse) in your read speeds. The settings are: poll_attributes (I believe this is 1800 default) md_num_stripes md_write_limit md_sync_window Thanks
September 6, 201510 yr Author I know this is an old post, but there was a response to what the defaults were on these numbers but I'm having a hard time searching the forum for them. I want to start off with defaults and run that tunable script. I did some minor memory changes and want to check for any improvements. 66MB/sec on a parity check is quite slow. Looking to improve the speed on that. poll_attributes (I believe this is 1800 default) md_num_stripes default? md_write_limit default? md_sync_window default?

These tunables let you control certain properties of the unRAID driver. Note: For each of these settings, if you delete the value and click Apply, the value is restored to its default.

Sorry for the confusion. I meant to ask what is the default of just the md_write_limit which is in the disk.cfg but not an option in the UI. Apparently it doesn't matter what I do, since I have the SAS2 cards which give me really slow parity check speeds regardless of what those settings are.
September 7, 201510 yr md_num_stripes default=1280 md_write_limit default=768 md_sync_window default=384
September 7, 201510 yr I don't think that setting is used anymore. You would have to try a completely fresh install on a different usb drive to verify (without disrupting your existing install).
September 7, 201510 yr The md_write_limit setting is still in the disk.cfg file (whether or not it is used, I don't know), but, it is not exposed in the GUI.
September 7, 201510 yr The md_write_limit setting is still in the disk.cfg file (whether or not it is used, I don't know), but, it is not exposed in the GUI. but is that on a clean install or from a legacy install?
September 7, 201510 yr Good question. I did a "clean" install when I migrated to unRAID 6.0 however, I preserved the config folder from v5, so, I guess I have not done a true clean install and disk configuration since moving to v6.x. It could be that md_write_limit is no longer used in 6.x.
