Hello all,

I tried again to install Swift only ontop of a Raspberry Pi 3 with
Rapbian and I followed this time the instructions "SAIO - Swift All In
One"

https://docs.openstack.org/developer/swift/development_saio.html

The installation went well and the service is running, but I still
cannot upload files into the service. The error message is still this
one on client side:

Object PUT failed:
http://10.0.0.253:8080/v1/AUTH_test/s3perf-testbucket/testfiles/s3perf-testfile1.txt
503 Service Unavailable  [first 60 chars of response]
<html><h1>Service Unavailable</h1><p>The server is currently

and this one inside the file storage1.error:

May 24 13:15:15 raspberrypi object-server: ERROR __call__ error with PUT
/sdb1/484/AUTH_test/s3perf-testbucket/testfiles/s3perf-testfile1.txt :

(txn: txdfe3c7f704be4af8817b3-0059256b43)

I tried the installation instructions inside virtual machine with
Ubuntu 14.04 and there is no problem. The service runs and I can
upload files without any error.

Has anybody here an idea how to locate the root cause of this issue
and how to fix it?

Hello,

Creating and erasing buckets (containers) in my single node Swift only
installation works well, but any attempt to upload a file causes just
an error message.

I have started Swift as user pi and assigned these folders to this user:

$ sudo chown pi:pi /etc/swift
$ sudo chown -R pi:pi /mnt/sdb1/*
$ sudo chown -R pi:pi /var/cache/swift
$ sudo chown -R pi:pi /var/run/swift

sdb1 is a loopback device with the XFS file system.

I deployed Swift this way:
https://github.com/christianbaun/s3perf/wiki/Swift-on-a-Raspberry-Pi-3-with-Raspbian-%28Debian-Jessie-8.0%29

I wonder why creating buckets (containers) works well, but the upload
of a file fails because of "Permission denied".
