Centos7.5運行iotop報錯

centos 7.5 的服務器上執行iotop命令發現報如下錯誤：
出錯原因:Centos7.5的status信息不一定是:\t來分割信息的了，所以分割會出現有些信息分割出來只有一個key，沒有value，目前iotop還沒更新過來，所以臨時解決辦法就是跳過這些分割出來只有一列的信息。
[root@UAT/]# iotop

ValueError: need more than 1 value to unpack

按照如下方法可以解決

[root@UAT/]# vim /usr/lib/python2.7/site-packages/iotop/data.py

def parse_proc_pid_status(pid):
    result_dict = {}
    try:
        for line in open('/proc/%d/status' % pid):
            key, value = line.split(':\t', 1)
            result_dict[key] = value.strip()
    except IOError:
        pass  # No such process
    return result_dict

修改爲

def parse_proc_pid_status(pid):
    result_dict = {}
    try:
        for line in open('/proc/%d/status' % pid):
            try:
                key, value = line.split(':\t', 1)
            except:
                break
            result_dict[key] = value.strip()
    except IOError:
        pass  # No such process
    return result_dict

在執行iotop正常
