Symptoms

由使用者變更為使用者介面上的儲存器擁有者頁面：
kA23a0000000BOMCA2_3_0

此問題適用于啟用 NFS 的儲存器，以及使用者介面變更儲存器擁有者。這可能會導致已連線的應用程式或使用者無法存取 Linux 檔案系統上的儲存器。即使我們再次將變更還原至原始擁有者，也無法再次存取，導致 DU。

在此範例中：
儲存器擁有者已使用使用者介面變更為「sham2」。由於 ECS 的限制，甚至在將儲存器擁有者名稱變更為「sham1」之後仍如此。ECS 不會使用使用者介面將儲存器擁有者變更為「sham1」。現在只能在 CLI 使用具有負載的 API，將系統旗標重新設定為 true 時，才能完成此作業。

在 Linux 機器上找出問題的方法，請使用者觸碰檔案，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"
svc_log v1.0.22 (svc_tools v1.5.3)                 Started 2019-06-06 10:45:04

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

Cause

以特定使用者作為擁有者建立儲存器，然後變更儲存器的擁有權。最後，讓原始擁有者使用 ACL 頁面完全掌控失敗，並顯示 ECS 記錄例外狀況：

ObjectControllerException: method updateObjectInternal not allowed for previous bucket owner <ownerid>
This is a known issue currently being evaluated by Dell EMC at this time.

Resolution

因應措施是透過含負載的 CLI 使用 API 將儲存器擁有者變更為 true。

1.決定目前的儲存器擁有者。

要求使用者介面根密碼產生 TOKEN。例如：

admin@ecsnode1:~> tok=$(curl -iks https://XX.XX.XX.XX:4443/login -u 'root:ChangeMe' | grep X-SDS-AUTH-TOKEN)

確認目前的儲存器擁有者（在您的情況下，替換儲存器和命名空間）：

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>

這會確認必須將reset_previous_owners參數設為 true。還原的儲存器擁有者位於使用者介面上，但透過命令列介面（CLI）的 API 可確認 ECS 仍將儲存器擁有者視為「sham2」。

2.使用 vi 編輯器建立簡單的 xml 檔案。在下方的範例中，稱為/tmp/bucket-owner.xml。這是兩個步驟的程式。我們必須暫時將它設為新的擁有者。第二個步驟。如以下範例所示，請先確認輸出，再重新設定為原始擁有者，並確認輸出：

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.

透過 xml 檔案將儲存器擁有者變更為「sham2」所需的 API 語法如下：

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.

確認儲存器擁有者變更現在是「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 上還原儲存器擁有者後，請確認主機現在可以存取 Linux 檔案系統上的儲存器。

.7. 組態變更完成後，我們不應再看到相同的錯誤

svc_log -f "method updateObjectInternal not allowed" -start "20 hour ago" -sr all -sh -st hour
