写个GPFS 部署脚本

GPFS（General Parallel File System）是一个高性能并行文件系统，主要用于大型集群的数据管理。下面是一个简单的 GPFS 部署脚本示例，仅供参考：

#!/bin/bash

# 安装依赖项
yum install -y ksh gcc gcc-c++ make kernel-devel

# 下载 GPFS 安装包
wget https://public.dhe.ibm.com/storage/gluster/gpfs/gpfs_4.2.3.0/gpfs_rpms-x86_64-4.2.3.0.tar.gz

# 解压安装包
tar zxvf gpfs_rpms-x86_64-4.2.3.0.tar.gz

# 安装 GPFS
cd gpfs_rpms-x86_64-4.2.3.0
./gpfs.base.installer

# 配置 GPFS
/opt/ibm/gpfs/sbin/mmcrcluster -N mycluster -p /usr/bin/ssh
/opt/ibm/gpfs/sbin/mmcrnsd -N mycluster -p /usr/bin/ssh -S /dev/sdb

# 启动 GPFS
/opt/ibm/gpfs/sbin/mmstartup -a

这只是一个简单的示例脚本，实际的部署过程还需要根据具体情况进行调整。同时，需要注意的是，GPFS 的部署和配置相对复杂，建议在熟悉 GPFS 的情况下进行操作。

GPFS部署环境检查脚本

以下是检查IBM GPFS部署环境的脚本示例：

#!/bin/bash
# GPFS Environment Check Script

echo "Checking GPFS dependencies..."
# Check required packages are installed
rpm -qa | grep -q glibc-2.12 || { echo >&2 "glibc-2.12 not installed!"; exit 1; }
rpm -qa | grep -q kernel-headers-$(uname -r) || { echo >&2 "kernel-headers not installed!"; exit 1; }
rpm -qa | grep -q kernel-devel-$(uname -r) || { echo >&2 "kernel-devel not installed!"; exit 1; }
rpm -qa | grep -q libstdc++-4.4.7 || { echo >&2 "libstdc++-4.4.7 not installed!"; exit 1; }
rpm -qa | grep -q numactl-libs || { echo >&2 "numactl-libs not installed!"; exit 1; }

echo "Checking GPFS kernel parameters..."
# Check required kernel parameters are set
sysctl -q fs.file-max | grep -q '^[^#].*5242880' || { echo >&2 "fs.file-max not set to 5242880!"; exit 1; }
sysctl -q kernel.shmmax | grep -q '^[^#].*4294967296' || { echo >&2 "kernel.shmmax not set to 4294967296!"; exit 1; }
sysctl -q kernel.shmall | grep -q '^[^#].*2097152' || { echo >&2 "kernel.shmall not set to 2097152!"; exit 1; }
sysctl -q kernel.sem | grep -q '^[^#].*250 32000 32 512' || { echo >&2 "kernel.sem not set to 250 32000 32 512!"; exit 1; }
sysctl -q net.ipv4.ip_local_port_range | grep -q '^[^#].*1024 65535' || { echo >&2 "net.ipv4.ip_local_port_range not set to 1024 65535!"; exit 1; }
sysctl -q net.core.rmem_default | grep -q '^[^#].*262144' || { echo >&2 "net.core.rmem_default not set to 262144!"; exit 1; }
sysctl -q net.core.wmem_default | grep -q '^[^#].*262144' || { echo >&2 "net.core.wmem_default not set to 262144!"; exit 1; }
sysctl -q net.core.rmem_max | grep -q '^[^#].*16777216' || { echo >&2 "net.core.rmem_max not set to 16777216!"; exit 1; }
sysctl -q net.core.wmem_max | grep -q '^[^#].*16777216' || { echo >&2 "net.core.wmem_max not set to 16777216!"; exit 1; }

echo "GPFS environment check complete."

该脚本检查所需的软件包是否已安装，以及必需的内核参数是否设置为正确的值。如果检查失败，脚本将输出错误消息并退出。如果检查成功，则输出“GPFS environment check complete.”。请注意，该脚本需要以root用户身份运行才能执行sysctl命令。
