modsiw Posted August 27, 2019 Share Posted August 27, 2019 unraid 6.7.2, new build iostat reports 40%-80% iowait. sdf and sdf1 each appear twice with busybox iostat and are seriously thrashing io. Box is unbearably slow. Console log showing df and iostat: https://pastebin.com/raw/eBateMPw Diagnostics are attached. unraid-diagnostics-20190827-1141.zip Quote Link to comment
JorgeB Posted August 27, 2019 Share Posted August 27, 2019 Unraid releases after v6.7 have issues with simultaneous multiple array disk use. Quote Link to comment
modsiw Posted August 27, 2019 Author Share Posted August 27, 2019 (edited) Is it safe to drop back to version 6.6.x without wiping the data disks? (I can wipe them, but I'd rather not). edit: seems like that would be ok. Any ideas on why iostat reports the same device twice? Edited August 27, 2019 by modsiw Quote Link to comment

Yes. 14 minutes ago, modsiw said: Any ideas on why iostat reports the same device twice? Not sure, possibly because it's getting it also from the mdX device. Quote Link to comment
modsiw Posted August 27, 2019 Author Share Posted August 27, 2019 Downgraded to 6.6.7 . As expected this fixed the iowait %. Also, iostat is now reporting devices correctly. Perhaps that a clue for root cause analysis. Thanks for the help. Quote Link to comment
