Hello John,
Your "Swift on PI" instructions helped me a lot when I started my
attempt to get Swift running on the RPi3. I documented here what I
did:
https://github.com/christianbaun/s3perf/wiki/Swift-on-a-Raspberry-Pi-3-with-Raspbian-(Debian-Jessie-8.0)
I use the user pi and specified this in all configuration conf-files
inside /etc/swift. In order to get rid of the "Permission denied"
issue, i even gave /mnt/sdb1 and all subfolder full access privileges:
$ sudo chown -R pi:pi /mnt/sdb1/
$ sudo chmod -R 777 /mnt/sdb1/
$ mount | grep sdb1
/srv/swift-disk on /mnt/sdb1 type xfs
(rw,noatime,nodiratime,attr2,nobarrier,inode64,logbufs=8,noquota)
But the situation did not change. I can create buckets, but not upload objects.
Best Regards
Christian
