TeddyS. Posted February 22 Share Posted February 22 (edited) I just fully recreated my array after clearing all partitions and issuing a new config. I assigned all disks to the array and ran the format but the initial parity check after array boot is running extremely slowly (10 MBps or slower that dips down to 1 MBps frequently). I have already used the DiskSpeed docker plugin to verify all disks are operating at appropriate speeds and cannot figure out where the slow down is coming from. I would appreciate any help that can be given. Array is 11+1 8TB drives with the 1 as parity. Edited February 22 by teddyschell91 misstype Quote Link to comment
JonathanM Posted February 22 Share Posted February 22 Are you writing data to the array currently? Diagnostics may shed some light. Quote Link to comment

That may have been intentional based on the timeframe, I think when I saw initial slowness I paused the parity then issued a reboot on the host. That aside when I pulled it up this morning the speeds appear to have increased dramatically. Perhaps just an issue with early steps in the parity? Quote Link to comment
Rysz Posted February 23 Share Posted February 23 I'd still check if the cables are somehow loose on the board or the HDDs when the parity check is done. Just to be on the safe side... connection issues can cause a lot of problems down the road even if it works now. Quote Link to comment

TeddyS. Posted February 23 Author Share Posted February 23 Understood perhaps a SATA connection issue somewhere. I will check them over. Quote Link to comment

No recent changes at the moment, I do have I think two SATA power extensions to add 4 more connections off the existing SATA chain cable. Maybe one is loose. Quote Link to comment
