Veah Posted July 31, 2023 Share Posted July 31, 2023 I didn't think they did. It's been so long since I really had to know this stuff that it's easy for me to doubt my memory or just think things have changed again. Hoping OP gets the fix being searched for regardless. Quote Link to comment
Deagarys Posted July 31, 2023 Author Share Posted July 31, 2023 (edited) It is still running the parity-sync/rebuild. it says it will take days. im certain this is because one of my old drives is bottlenecking me. I ordered a new one toay which will arrive tomorrow. If it takes too long ill try draining the drive and replacing it. But hopefully the rebuild speeds up soon and i can replace the old drive tomorrow the normal way. Edited July 31, 2023 by Deagarys Quote Link to comment

Veah Posted July 31, 2023 Share Posted July 31, 2023 Oof. That's rough. Hope it's not your biggest capacity. Quote Link to comment

Veah Posted July 31, 2023 Share Posted July 31, 2023 I have some old 1tb WD Greens that hold back my parity checks to ~80MBps speeds. My others are 18TB Exos. Once the WDs finish at about 6% of the check, the speeds pick right up to ~230MBps for the rest. So the initial prediction time drops a lot at my 6% mark. Found it fascinating when I noticed it.

On the Dashboard page, the drive will show a SMART warning ( 👎 ) . You can click on it to acknowledge the current count and it will warn again if it increases. For the occasional CRC, I just acknowledge, maybe reseat the connection next time I'm in the case. Certain other SMART attributes are monitored also, these are more important and can indicate actual drive problems. You should setup Notifications to alert you be email or other agent as soon as a problem is detected. Don't let one ignored problem become multiple problems and data loss. Quote Link to comment
Deagarys Posted August 3, 2023 Author Share Posted August 3, 2023 UPDATE: Parity check completed after 2+ days, parity showed up as valid. Removed the parity drive and replaced it by a new one. Rebuild was done in 8 hours. New drive much faster im no longer bottlenecked. Everything is up and working! Thanks for all the help! Quote Link to comment
