I have an external RAID array with several disks. I am unable to reset permissions. For example:

sudo resetUserPermissions /Volumes/Data/ `id -u`


Ready to reset user permissions on disk5 Data
Started verify/repair permissions on disk5 Data
Error: -69838: Operation not supported for the macOS version on the targeted disk

According to this Apple Support post, I tried this as well:

sudo chflags -R nouchg /Volumes/Data/

That runs to completion (successfully), but I still get the same error -69383 when I try to reset user permissions.

OS X High Sierra (10.13.6), with SoftRaid 5.6.7
