Avamar：嘗試啟動 Avamar 備份排程器時發生錯誤「exit status 1」

Avamar 工具節點已更換。 

重新啟動 Avamar 備份排程器會導致錯誤：

admin@Lab-AVE:~/>: dpnctl start sched
dpnctl: INFO: Resuming backup scheduler...
dpnctl: ERROR: error return from "[ -r /etc/profile ] && . /etc/profile ; /usr/local/avamar/bin/mccli mcs resume-scheduler" - exit status 1
dpnctl: INFO: No /usr/local/avamar/var/dpn_service_status exist.
dpnctl: INFO: [see log file "/usr/local/avamar/var/log/dpnctl.log"] 

MCCLI 命令失敗，並顯示如下訊息：

admin@Lab-AVE:~/>: mccli server show-services
1,22801,User login failure. 

admin@Lab-AVE:~/>: mccli server show-services
1,22801,User login failure.

可使用 MCUser 密碼位於 mcclimcs.xml 檔案與以下位置的密碼不同： /usr/local/avamar/var/mc/server_data/prefs/mcserver.xml 檔案中所定義。

若要尋找 mcclimcs.xml 的版本，請以 root 身分執行 find 命令：

root@Lab-AVE:~/#: find / -name "mcclimcs.xml" -print

輸出範例： 

虛擬節點：

/space/home/admin/.avamardata/var/mc/cli_data/prefs/mcclimcs.xml 
/usr/local/avamar/lib/mcclimcs.xml
/root/.avamardata/var/mc/cli_data/prefs/mcclimcs.xml

實體節點：

/data01/home/admin/.avamardata/var/mc/cli_data/prefs/mcclimcs.xml 
/usr/local/avamar/lib/mcclimcs.xml
/root/.avamardata/var/mc/cli_data/prefs/mcclimcs.xml

1.確認加密的 MCUser 密碼在 mcclimcs.xml 檔案與以下檔案不相符 mcserver.xml：

root@Lab-AVE:~/#: grep MCUSERAP /usr/local/avamar/var/mc/server_data/prefs/mcserver.xml
                <entry key="MCUSERAP" value="{AES}8gjyd5nnLnCa3e1cbNBAvg==" />

root@Lab-AVE:~/#: grep mcspasswd /space/home/admin/.avamardata/var/mc/cli_data/prefs/mcclimcs.xml /usr/local/avamar/lib/mcclimcs.xml /root/.avamardata/var/mc/cli_data/prefs/mcclimcs.xml |grep -v password
/space/home/admin/.avamardata/var/mc/cli_data/prefs/mcclimcs.xml:       mcspasswd="{AES}abcdd5nnLnCa3e1cbNBAva=="
/usr/local/avamar/lib/mcclimcs.xml:       mcspasswd="{AES}abcdd5nnLnCa3e1cbNBAva=="
/root/.avamardata/var/mc/cli_data/prefs/mcclimcs.xml:       mcspasswd="{AES}abcdd5nnLnCa3e1cbNBAva==" 

2.建立現有 /usr/local/avamar/lib/ 中的 mcclimcs.xml 檔案備份複本 （這三個位置的檔案均相同，一個備份複本即已足夠）：

root@Lab-AVE:~/#: cp -p /usr/local/avamar/lib/mcclimcs.xml /usr/local/avamar/lib/orig_mcclimcs.xml_`date -I`

3.確認備份複本是否存在：

root@Lab-AVE:~/#: ls -lah /usr/local/avamar/lib/ |grep mcclimcs.xml
-rw-r-----  1 root  admin  1.2K Nov  1 15:00 mcclimcs.xml
-rw-r-----  1 root  admin  1.2K Nov  1 15:00 orig_mcclimcs.xml_2025-03-26 

4.使用 sed 編輯每個 mcclimcs.xml 檔案，將不正確的加密密碼替換為從 mcserver.xml。  

以上範例檔中的命令範例。

root@Lab-AVE:~/#: sed -i '/mcspasswd/s/"{AES}abcdd5nnLnCa3e1cbNBAva=="/"{AES}8gjyd5nnLnCa3e1cbNBAvg=="/g' /space/home/admin/.avamardata/var/mc/cli_data/prefs/mcclimcs.xml

root@Lab-AVE:~/#: sed -i '/mcspasswd/s/"{AES}abcdd5nnLnCa3e1cbNBAva=="/"{AES}8gjyd5nnLnCa3e1cbNBAvg=="/g' /usr/local/avamar/lib/mcclimcs.xml

root@Lab-AVE:~/#: sed -i '/mcspasswd/s/"{AES}abcdd5nnLnCa3e1cbNBAva=="/"{AES}8gjyd5nnLnCa3e1cbNBAvg=="/g' /root/.avamardata/var/mc/cli_data/prefs/mcclimcs.xml

5.確認加密的密碼與所有檔案相符：

root@Lab-AVE:~/#: grep MCUSERAP /usr/local/avamar/var/mc/server_data/prefs/mcserver.xml
                <entry key="MCUSERAP" value="{AES}8gjyd5nnLnCa3e1cbNBAvg==" 

root@Lab-AVE:~/#: grep mcspasswd /space/home/admin/.avamardata/var/mc/cli_data/prefs/mcclimcs.xml /usr/local/avamar/lib/mcclimcs.xml /root/.avamardata/var/mc/cli_data/prefs/mcclimcs.xml |grep -v password
/space/home/admin/.avamardata/var/mc/cli_data/prefs/mcclimcs.xml:       mcspasswd="{AES}8gjyd5nnLnCa3e1cbNBAvg=="
/usr/local/avamar/lib/mcclimcs.xml:       mcspasswd="{AES}8gjyd5nnLnCa3e1cbNBAvg=="
/root/.avamardata/var/mc/cli_data/prefs/mcclimcs.xml:       mcspasswd="{AES}8gjyd5nnLnCa3e1cbNBAvg==" 

6.這些命令現在應可完成，不會發生任何問題：

admin@Lab-AVE:~/>: dpnctl status sched
dpnctl: INFO: Backup scheduler status: down. 

admin@Lab-AVE:~/>: dpnctl start sched
dpnctl: INFO: Resuming backup scheduler...
dpnctl: INFO: Backup scheduler resumed.
dpnctl: INFO: No /usr/local/avamar/var/dpn_service_status exist. 

admin@Lab-AVE:~/>: dpnctl status sched
dpnctl: INFO: Backup scheduler status: up. 

admin@Lab-AVE:~/>: mccli server show-prop |egrep "Attrib|---|State|Sys|HFSAddr"

---------------------------------- --------------------------

如有需要，以下是每個 mcclimcs.xml 檔案的正確權限和擁有權清單：

ls -lah /space/home/admin/.avamardata/var/mc/cli_data/prefs/mcclimcs.xml
-rw-r----- 1 admin admin 1.2K Mar 26 17:04 /space/home/admin/.avamardata/var/mc/cli_data/prefs/mcclimcs.xml

ls -lah /usr/local/avamar/lib/mcclimcs.xml
-rw-r----- 1 root admin 1.2K Mar 26 17:05 /usr/local/avamar/lib/mcclimcs.xml

ls -lah /root/.avamardata/var/mc/cli_data/prefs/mcclimcs.xml
