在我的 OpenStack Swift 2.14.0 版安装中创建和删除存储桶(容器)效果很好。这是一个仅限 Swift 的安装。没有进一步部署像 Keystone 这样的 OpenStack 服务。
$ swift stat

我已经以用户
pi 的身份启动了 Swift，并将这些文件夹分配给了这个用户:$ 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 是一个带有 XFS 文件系统的环回设备。$ mount | grep sdb1
/srv/swift-disk on /mnt/sdb1 type xfs (rw,noatime,nodiratime,attr2,nobarrier,inode64,logbufs=8,noquota)
$ ls -ld /mnt/sdb1/1/

我部署了 Swift this way 。
我想知道为什么创建存储桶(conrainers)有效，但由于
Permission denied 导致文件上传失败。更新 1:

当我创建一个存储桶时，Swift 服务会创建一个这样的文件夹:
/mnt/sdb1/1/node/d1/containers/122/9d5/7a23d9409f11da3062432c6faa75f9d5/
这个文件夹包含一个
db 文件，比如 7a23d9409f11da3062432c6faa75f9d5.db 。我认为这是正确的行为。但是当我尝试在存储桶中上传文件时，Swift 只会创建一个像这样的空文件夹。
/mnt/sdb1/1/node/d1/objects/139/eca/8b17958f984943fc97b6b937061d2eca
我可以作为用户
touch 通过 echo 或 pi 在这些空文件夹中创建文件，但由于未知原因，Swift 不会将文件存储在这些文件夹中。更新 6
为了进一步调查这个问题，我根据 SAIO - Swift All In One 说明安装了 Swift，一次是在装有 Ubuntu 14.04 LTS 的 VMware ESXi 虚拟机中，另一次是在 Raspberry Pi 3 上的 Raspbian 中。结果是，在 Ubuntu 14.04 虚拟机中， Swift 运行良好，但在 Rasberry Pi 上运行时，无法上传文件。

问题仍未解决，但我现在在 Raspberry Pi 上有一个可用的 Swift 服务。我安装了(相当过时的)Swift 修订版 2.2.0，它随 Raspbian 一起提供并且运行良好。 here 解释了我所做的步骤。
最佳答案
根据您提供的信息，在写入元数据时出现错误。
写入元数据的操作分为两类:操作inode和操作扩展属性。因此，您的错误有两个可能的来源。
首先，它是与 inode 相关的错误。由于设置了 inode64，可能会出现此错误。安装设备时的参数。根据XFS man page :
If applications are in use which do not handle inode numbers bigger than 32 bits, the inode32 option should be specified.
其次，是扩展属性相关的错误。您可以使用
xattr python包来编写扩展属性，并检查是否发生异常。
关于permissions - 由于 "[Errno 13] Permission denied"，无法在 Raspberry Pi 3 上将文件上传到 OpenStack Swift 2.14.0，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/43869659/
