Symptoms

  • Networker 19.4 
  • Isilon 8.2
  • NDMP 备份有错误：“打开的文件太多”。

Cause

Isilon 8.2 在 Isilon isi_ndmp_d 中具有打开文件限制。

Resolution

“打开的文件太多”是一个已知问题。建议将打开文件限制提高至 isi_ndmp_d。
  1. 编辑 /etc/mcp/sys/services/ndmpd 文件并增加max_open_files
<action>/bin/sleep 30</action>
<action>/usr/bin/limits -B -P $（pgrep isi_ndmp_d） -n 32768</action>
  1. 在任何节点上编辑 ndmpd：
cd /etc/mcp/sys/services
cp ndmpd /ifs/data/Isilon_Support
vi /ifs/data/Isilon_Support/ndmpd
  1. <在 actionlist name=“start”> 部分中，添加以下行：
<action>/bin/sleep 30</action>
<action>/usr/bin/limits -B -P $（pgrep isi_ndmp_d） -n 32768</action>

示例： 
<?xml version="1.0"?>
<service name="ndmpd" enable="0" display="1" options="require-quorum,kill-on-sigquorum,require-post-ifs">
      <isi-meta-tag id="ndmp_service">
        <mod-attribs>enable</mod-attribs>
      </isi-meta-tag>
      <description>Network Data Management Protocol Daemon</description>
      <process name="isi_ndmp_d" pidfile="/var/run/isi_ndmp_d.pid"
               startaction="start" stopaction="stop"/>
      <actionlist name="start">
        <action>/usr/bin/isi_ndmp_d</action>
        <action>/bin/sleep 30</action>
        <action>/usr/bin/limits -B -P $(pgrep isi_ndmp_d) -n 32768</action>
      </actionlist>
      <actionlist name="stop">
        <action>/usr/bin/killall isi_ndmp_d</action>
      </actionlist>
</service>
  1. 保存文件（可能必须使用 ！，因为该文件是只读的）
  2. 然后将文件分发到所有节点：
isi_for_array 'cp /ifs/data/Isilon_Support/ndmpd /etc/mcp/sys/services'
  1. 重新启动 NDMP 服务：
isi services ndmpd disable
isi services ndmpd enable
  1. 检查 isi_ndmp_d PID 的打开文件限制：
isi_for_array 'procstat -l $（pgrep isi_ndmp_d）|grep openfiles' 
dklimki-mr1512e-4: 26547 isi_ndmp_d       openfiles              16384            16384            
dklimki-mr1512e-5: 77179 isi_ndmp_d       openfiles              16384            16384            
dklimki-mr1512e-3: 74909 isi_ndmp_d       openfiles              16384            16384            
dklimki-mr1512e-1: 27389 isi_ndmp_d       openfiles              16384            16384            
dklimki-mr1512e-2:  3725 isi_ndmp_d       openfiles              16384            16384  
  1. 30 秒后再次检查：
isi_for_array 'procstat -l $（pgrep isi_ndmp_d）|grep openfiles' 
dklimki-mr1512e-3: 74909 isi_ndmp_d       openfiles              32768            32768
dklimki-mr1512e-1: 27389 isi_ndmp_d       openfiles              32768            32768
dklimki-mr1512e-2:  3725 isi_ndmp_d       openfiles              32768            32768
dklimki-mr1512e-4: 26547 isi_ndmp_d       openfiles              32768            32768
dklimki-mr1512e-5: 77179 isi_ndmp_d       openfiles              32768            32768
