Symptômes

用户对 用户界面上的存储桶所有者页面所做的更改:
kA23a0000000BOMCA2_3_0

此问题适用于启用了 NFS 的存储区以及通过用户界面更改存储区所有者。这可能会导致连接到的应用程序或用户失去对 Linux 文件系统上的存储区的访问权限。即使我们将更改再次恢复给原始所有者,也无法进行访问,从而导致 DU。

在此示例中:
存储区所有者已使用用户界面更改为“sham2”。由于 ECS 中的限制,即使在将存储区所有者名称更改回“sham1”之后也是如此。ECS 不会使用用户界面将存储区所有者更改回“sham1”。目前只能通过 CLI 使用带有有效负载的 API 来完成此操作,以便将 resetowner 标记设置为 true。

识别问题的方法,在 Linux 计算机上要求用户触摸文件,例如:
admin@node1~>touch file
touch: setting times of `file': Remote I/O error

se svc_log with the string  "method updateObjectInternal " 

Command:
# svc_log -a -sr dataheadsvc | grep "method updateObjectInternal"
Example:

admin@node1~>svc_log -a -sr dataheadsvc | grep "method updateObjectInternal"

Caused by: com.emc.storageos.data.object.exception.ObjectControllerException: method updateObjectInternal not allowed for previous bucket owner sham1

Cause

使用特定用户作为所有者创建存储区,然后更改存储区的所有权。最后,使用 ACL 页面向原始所有者授予完全控制权会失败,并出现 ECS 日志异常:
ObjectControllerException: method updateObjectInternal not allowed for previous bucket owner <ownerid>
This is a known issue currently being evaluated by Dell EMC at this time.

Résolution

解决方法是通过 CLI 使用 API 将存储区所有者更改为存储区所有者,并将有效负载更改为 resetowner 标记为 true。

1.确定当前存储区所有者。
需要用户界面 root 密码才能生成令牌。例如:
admin@ecsnode1:~> tok=$(curl -iks https://XX.XX.XX.XX:4443/login -u 'root:ChangeMe' | grep X-SDS-AUTH-TOKEN)

验证当前存储区所有者(在您的情况中替换存储区和命名空间):
admin@node1:~> curl -s -k -X GET -H "$tok" https://XX.XX.XX.XX:4443/object/bucket/sham_bk_nfs/info?namespace=degreat_nfs | xmllint --format - | grep '<owner>'
  <owner>sham2</owner>

这确认参数reset_previous_owners需要设置为 true。恢复的存储区所有者位于用户界面上,但通过 CLI 的 API 确认 ECS 仍将存储区所有者视为“sham2”。

2.使用 vi 编辑器创建简单的 xml 文件。在下面的示例中,它被称为 /tmp/bucket-owner.xml。这是一个多步骤过程。我们必须将其临时设置为 sham2 的新所有者。如下面的示例中所示,在设置回原始所有者 sham1 之前,请确认输出:
admin@node1:~ # vi /tmp/bucket-owner.xml

admin@ecsnode1:~ # cat /tmp/bucket-owner.xml
<object_bucket_update_owner>
   <namespace>degreat_nfs</namespace>
   <new_owner>sham2</new_owner>
   <reset_previous_owners>true</reset_previous_owners>
</object_bucket_update_owner>

3. Change the bucket owner to the temporary owner. 

通过 xml 文件将存储桶所有者更改为“sham2”所需的 API 语法如下:
admin@ecsnode1:~> curl -v -k -X "POST" "https://xx.xx.xx.xx:4443/object/bucket/sham_bk_nfs/owner" -H "$tok" -H "Content-Type: application/xml" -H "ACCEPT:application/xml" -d @/tmp/bucket-owner.xml -v

4. Edit the simple.xml file previously created in step 2 and this time insert original owner of sham1

admin@node1:~ # vi /tmp/bucket-owner.xml

admin@ecsnode1:~ # cat /tmp/bucket-owner.xml
<object_bucket_update_owner>
   <namespace>degreat_nfs</namespace>
   <new_owner>sham1</new_owner>
   <reset_previous_owners>true</reset_previous_owners>
</object_bucket_update_owner>

5. Change the bucket owner back to the original owner
The API syntax required to change the bucket owner back to "sham1" through the xml file is as follows:
admin@ecsnode1:~> curl -v -k -X "POST" "https://xx.xx.xx.xx:4443/object/bucket/sham_bk_nfs/owner" -H "$tok" -H "Content-Type: application/xml" -H "ACCEPT:application/xml" -d @/tmp/bucket-owner.xml -v

*        issuer: CN=localhost
*        SSL certificate verify result: self signed certificate (18), continuing anyway.

6.  Confirm the bucket owner change is reflected. 

确认存储桶所有者的更改现在为“sham1”。
admin@ecsnode1:~> curl -s -k -X GET -H "$tok" https://XX.XX.XX.XX:4443/object/bucket/sham_bk_nfs/info?namespace=degreat_nfs | xmllint --format - | grep '<owner>'
<owner>sham1</owner>

在 API 上恢复存储区所有者后,确认主机现在可以访问 Linux 文件系统上的存储区。

。7.配置更改完成后,我们应该不会再看到相同的错误
