权限 – 由于“[Errno 13] Permission denied”,无法将文件上传到Raspberry Pi 3上的OpenStack Swift 2.14.0_app

概述在我的OpenStack Swift版本2.14.0安装中创建和擦除存储桶(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 Account: AUTH_test Containers: 2 在我的OpenStack Swift版本2.14.0安装中创建和擦除存储桶(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.

$swift stat                        Account: AUTH_test                     Containers: 2                        Objects: 0                          Bytes: 0Containers in policy "policy-0": 2   Objects in policy "policy-0": 0     Bytes in policy "policy-0": 0                     Connection: keep-alive...$swift post s3perf$swift List -A http://10.0.0.253:8080/auth/v1.0 -U test:tester -K testingbuckets3perf

这些是关于文件storage1.error中的桶创建的(正)消息.

但任何上传文件的尝试都会导致错误消息[Errno 13]权限被拒绝.

proxy.error文件还包含错误消息ERROR 500 Expect：100-continue From Object Server.

我已经将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)有效但由于权限被拒绝而导致文件上传失败.

我可以在Swift应该存储对象的文件夹中写为用户pi.

所有swift进程都属于用户pi.

更新5

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/

此文件夹包含一个db-file,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作为用户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.

更新6

为了进一步研究这个问题,我根据SAIO – Swift All In One指令在Ubuntu 14.04 LTS的VMware ESXi虚拟机中安装了Swift,在RaspBerry Pi 3上安装了另一次在Raspbian内部.结果是,在Ubuntu 14.04 VM内部,Swift工作得很好,但是当在RasBerry Pi上运行时,上传文件不起作用.

更新7

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.我做的步骤在here中解释.

解决方法根据您提供的信息,在编写元数据期间会出现错误.

编写元数据的 *** 作分为两类： *** 作inode和 *** 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,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.
