August 27, 20196 yr 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
August 27, 20196 yr Community Expert Unraid releases after v6.7 have issues with simultaneous multiple array disk use.
August 27, 20196 yr Author 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, 20196 yr by modsiw

August 27, 20196 yr Author 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.
