Symptoms

在 Unity OE 5.1 或更高版本代码上执行 PUHC 可能会失败,并显示错误:

check_if_user_root_fs_has_enough_space_1

在 primary_sp/nas/log/check_health.<date>.log 文件中,则存在两个已知错误:

1) unknown host:

Data Movers: Check if user root fs has enough space
Command failed:
     * Command: /nas/bin/.server_config nas server -v "df"
     * Command output: Error 4023: nas : unknown host
     * Command exit code: 2
Action : Escalate this issue through your support organization.
     Provide this output in the escalation.

2) XML 解析错误:

Cause

在 Unity OE 5.1 代码之前,字符空格“ ”是 NAS 服务器名称中的有效字符。
在低于 5.1 的 Unity OE 版本上,包含字符空格的 NAS 服务器名称将通过 PUHC 检查。
对于 Unity OE 5.1 代码及更高版本,NAS 服务器名称中的空格被视为无效字符,不受支持。 

在 Unity OE 5.1 或更高版本代码上运行 PUHC 将会失败,并显示错误: <pre class=“> check_if_user_root_fs_has_enough_space_1当前 NAS 服务器名称中包含空格。
在 Unity OE 5.1 和更高版本的代码中,尝试创建名称中包含空格的 NAS 服务器将失败。  包含字符空格的非法 NAS 服务器名称的屏幕截图
尝试创建名称中包含字符空格的 NAS 服务器时生成的错误的屏幕截图
 XML parsing error: EOF looking for CDATA section end [Ln: 99, Col: 15]
A CDATA section starts with "<![CDATA[" and ends with "]]>".
<![CDATA[......]]>
Looks like CDATA EOF parsing issue.

Resolution

在上面的示例中,NAS 服务器名称“nas server”无效,将导致升级前运行状况检查失败。重命名 NAS 服务器以删除无效的空格字符,然后重新运行升级前运行状况检查。

如果重命名 NAS 服务器后问题仍然存在,请创建支持案例并引用此知识库文章。
