October 28, 20223 yr Hi guys, With the Scheduled parity check: Custom, is it possible to be even more granular than what's shown in the dropdowns? My usage of Unraid Mon-Thu is low, so the parity check (Accumulation) can run longer, whereby on weekends I tend to use it more often. I have a 12TB parity drive... so as you can imagine it takes "what-seems-like-forever" to get to 100%.
October 28, 20223 yr Community Expert You can install the Parity Check Tuning plugin to give you more control. It may be sufficient to simply use the plugins standard option to move parity check increments out of prime time. With that plugin one of the scheduling options is ‘Custom’ which can give you anything supported via a Linux crontab type entry which gives even more control. If there is some sort of schedule you would like to use that would not be satisfied by that then please describe it in more detail. I do not promise anything but would see if the plugin could be made to accommodate it in any way.

(really like that feature).. except.. post the end of the accumulation duration, all drives are on and running (this is some 2hours post the end duration/time) with nothing connected to the server. I have since shutdown, and reorganised the hot WD drives into a position next to a fan. My wish list for the "Parity Check Tuning" would be to have different start/end times per day (rather than a 1 size fits all approach). Perhaps a future feature? would be to "watch" the activity of the server say over 24x7 and to suggest a schedule based on periods/blocks of inactivity...

This implies that you do not have the drives set to spin down or have a long spin down time set? The plugin is spindown aware so will not spin up drives if the check has been stopped due to overheating and they are spun down in a cooling period. I added this as in the past there have been users who needed this as the drives would not spin down sufficiently to resume the check if they were kept spinning even though they were not being accessed. This allowed such users to set reasonably aggressive spindown times (e.g. 15 minutes). It is only when the check gets resumed that any drives still involved in the check get automatically spun up by Unraid as they are accessed. Your comment makes me think that if I can find a way to spin down drives reliably it might be worth adding an option to the plugin to try to explicitly spin down drives at the end of the check. Not sure how much value this would add, though, as the user could just as easily set a reasonably aggressive spin down time for the drives themselves so feedback on this idea would be welcomed. I can think about a more complicated scheduling option, but not sure about how easy it will be to present this in the GUI in a sensible way without quite a lot of work. It might be possible to add it as a “hidden” option without GUI support where you have to edit the plugin’s .cfg file directly - would this be an acceptable compromise?

As a UX dev with > 15yrs experience, the webGui use of VueJS together with Jquery, Bootstrap and PHP ..is very *ahem*... unusual.. 🤪 Yes 100%, a hidden option without GUI support would be more than acceptable!... Bazinga! 🙂
