linux7.x根盘原298G，需要扩容增加500G。
实现目标效果如下：
首先需要从虚机平台添加500硬盘到当前虚机。
系统上partprobe，lsblk查看是否识别到添加的盘。
如果不识别，则参考处理即可https://sqlora.blog.csdn.net/article/details/122358881
脚本参考：
[root@localhost ~]# cat scan.sh
#!/bin/bash
# Rescan SCSI bus
for host in /sys/class/scsi_host/*; do
echo "- - -" > ${host}/scan
done
[root@localhost ~]# chmod +x scan.sh
[root@localhost ~]# ./scan.sh
否则需重启系统才能识别。
系统上的扩容步骤：
1.pvcreate建pv
2.vgextend扩vg
3.lvextend扩lv
4.xfs_growfs扩fs (如果是ext3/4文件系统，则用resize2fs)
操作完整记录参考如下：
