在我的OpenStack Swift版本2.14.0安装中创建和删除存储桶（容器）效果很好。这是一个Swift唯一的安装。没有部署像Keystone这样的OpenStack服务。
$ swift stat

$ swift post s3perf
$ swift list -A http://10.0.0.253:8080/auth/v1.0 -U test:tester -K testing

这些是关于文件storage1.error内的存储桶创建的（正面）消息。

我已将Swift作为用户pi启动，并将这些文件夹分配给该用户：
$ 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/
drwxr-xr-x 3 pi pi 17 May 12 13:14 /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。

当我创建一个存储桶时，Swift服务会创建一个像这样的文件夹：
/mnt/sdb1/1/node/d1/containers/122/9d5/7a23d9409f11da3062432c6faa75f9d5/
此文件夹包含db文件，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只创建一个像这样的空文件夹。
/mnt/sdb1/1/node/d1/objects/139/eca/8b17958f984943fc97b6b937061d2eca
我可以通过touch或echo以用户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。

为了进一步研究这个问题，我根据SAIO - Swift All In One指令在VMware ESXi虚拟机中使用Ubuntu 14.04 LTS进行了一次安装，另一次在Raspberry Pi 3上使用Raspbian进行安装。结果是，在Ubuntu 14.04 VM中，Swift工作得很好，但是当在Rasberry Pi上运行时，上传文件不起作用。

问题仍然没有解决，但我现在在Raspberry Pi上有一个有效的Swift服务。我安装了（相当过时的）Swift 2.2.0版，它随Raspbian一起提供，效果很好。我所做的步骤解释为here。
答案 0 :(得分：1)
根据您提供的信息，在编写元数据时会出现错误。
编写元数据的操作分为两类：操作inode和操作扩展属性。因此，您的错误有两种可能的来源。
首先，它是与inode相关的错误。由于在安装设备时设置inode64参数，可能会发生此错误。根据{{3}}：
如果正在使用的应用程序不处理大于32位的inode编号，则应指定inode32选项。
其次，它是与扩展属性相关的错误。您可以使用python的xattr包来编写扩展属性，并检查是否发生异常。
