Hi mate sorry for the late reply, no i have had no issues with this board, might be the usb stick you are using? or something in the boot menu?

Hi All, I was wondering which of these the community recommends for a Movie server. Basically minimal writes and then mostly will be read only for the drives life. I run the drives on a spin up/spin down as needed basis. Would the Ironwolf or Exos be better in terms of long term survival rates when used like this. Cheers!

ty! So if a drive is still good and you simply take it out to replace it with a larger one, if anything does happen wold that prior working drive be able to simply put back into the array in its prior position? I did not know that was the case?

Hi all! I am wanting to start replacing some data drives one by one every few months with 10tb ones, some are approaching 7 years old and whilst i currently have no bad sectors on them i want to get a head start! I have an array of 8 drives (non hot swap) 2 drives are 10tb Parity drives that are about a year old. The other 6 data drives are 8tb. Am i good to just stop the array, turn off the servers, swap the disc out with the new one, when the server starts make sure auto start array is off, preclear the disc whilst the array is idle, after preclear select the new disc and let the array rebuild/re sync? Is a preclear still best practice? Should i be good with 2 parities to be doing this not really concerned? I have seen people empty the disc using unbalance first but that seems a bit tedious and unnecessary ? Thank you for all the advice and ongoing support!

I thought i hit non correcting check last night but i must of left it checked because it said it corrected the 5 errors. I re ran a check this time selecting perform correcting check and it has completed saying (0) errors corrected so seems like its all good either way now? unraid-diagnostics-20230604-1404.zip

Ok So just got back home, its found the same 5 errors again, at this point i just go ahead and perform a correcting check?

Really strange, they are both connected fine and they are off different sas to sata runs. They are both on the (p1) cables though funny enough

Ok Just finished the parity check still just the (5) errors. unraid-diagnostics-20230602-0939.zip

I am just finishing up the parity check after 2 nights its at 92%, funny enough first time i have ever seen sync errors? i have (5) i don't know if this is caused by a partial parity check one night, then adding data while its been paused then continuing the parity check over the second night? The first night it got to 53% and i saw no errors. So now i just don't add anything else, make sure all cables are set run a grueling correcting check and then re check again? there goes 4 days i guess?

Cool way of explaining it!

Thanks gents! i will get the smaller 510w one and move on! Cheers

Ok i have turned off auto corrections in the scheduler, i have also enabled cumulative checks turned onto 'daily' with a 7 hour duration so hopefully over 2 nights it does the trick! On the main tab next to 'CHECK' under 'Stop' there is still the blue tick 'write corrections to parity' is this only enabled for a manual parity check or in the case of a dirty power off?

I ended up giving up on the hot swap, any reason why the scheduled parity checks should be non correcting? what happens when you have sync errors if ever after a parity check?

Maybe going from the 450w to the 750w was a bit overkill but went from a Bronze to a Platinum PSU haha! Ok so should be good with the lower watt UPS for safe shutdown only?

Ahh that makes sense! So split it into rough estimates. Awesome thank you kindly Sir!

Mini ITX, Pentium g4650, 4gb DDR, 8 x Ironwolf Drives, Corsair 750w PSU. I would estimate the system to be around 400w max at full spin up. Once spin up probably a lot lower then that.

Will the standard plugin say let me do 50% one night and the remaining 50% the following night?

Well that sucks haha! i still think though its good value for money and the replacement batteries are also reasonably priced. Hopefully the newer models dont have as many issues? Its either the 510 Watt or the 750w, they both use the same battery. The second is 100 AUD more expensive, i only want it to perform a safe shutdown with a power outage so i am probably ok with the 510w?

Is it the case that cyberpower UPS is also plug and play with the default plugin?

Ok so all good, everything up, phew that took a while! So moving forward will my monthly parity checks do both he parity drives at the same time? Can i expect the parity check to take as long as the Parity rebuild because if that is the case i may have to spread it across two nights?

Actually this one seems like it could work, https://www.scorptec.com.au/product/ups/ups/51058-5s850au It says it has a HID-USB COMS Port Do you have to use NUC addon for any non ATC UPS?

These are more expensive in Australia compared to ATC for whatever reason!

When i am looking for one that will work well with Unraid software IE ATC ups, am i looking for one that says 'Line Interactive'? or is that not important? 2 potential models, https://www.centrecom.com.au/apc-650w12kva-back-ups https://www.centrecom.com.au/apc-easy-750va-ups-line-interactive

Sorry to revive an old thread, but i am looking at various ups options, my array is calculated to draw approx 450w at full spin up, i have a 750w psu installed, should i be looking at UPS's that are greater then 450w or 750w?

I just re looked over it, most drives on Attribute one also have values over 0. Under 'failed' it says never. So what do you look out for? a combination of these numbers starting to rise? Or is it really the bad sector and unrecoverable sector count?
