海康安防服务器2025磁盘扩容30GB
发现磁盘占用超过90%，为接下来的数据清理做准备：# df -h（获取整体状况）
Filesystem SizeUsed Avail Use% Mounted on
/dev/mapper/centos_hikvisionos-opt 119G108G 12G91% /opt
# du -sh /opt（目录空间占用）
108G /opt
查看日志文件空间占用情况
find /opt -type f -size +100M -name "*.log"
find /opt -type f -name "*.log" -exec du -ch {} + | grep total
# du -s /opt
112625504 /opt
应用程序产生的日志基本都在（62G）
/opt/hikvision/web/components/
安装包基本都在（32G）
/opt/hikvision/web/packages/
# du -s /opt
112487924 /opt
先找出超过100MB的日志文件
# find /opt -type f -size +100M -name "*.log"
/opt/hikvision/web/components/sac.1/bin/common/sh_logs/mdb_check.log
/opt/hikvision/web/components/artemis.1/bin/artemis/logs/hik.artemis.artemis.1.log
/opt/hikvision/web/components/consul.1/bin/consul/logs/consul/consul.log
清空这3个日志文件
cat /dev/null > /opt/hikvision/web/components/sac.1/bin/common/sh_logs/mdb_check.log
cat /dev/null > /opt/hikvision/web/components/artemis.1/bin/artemis/logs/hik.artemis.artemis.1.log
cat /dev/null > /opt/hikvision/web/components/consul.1/bin/consul/logs/consul/consul.log
# du -s /opt
111800564 /opt
接下来，专门清理tomcat85的日志文件（注意，这里不支持用通配符*.log，否则报错ambiguous redirect）
先删除已归档的*.zip文件
rm -f /opt/hikvision/web/components/tomcat85linux64.2/logs/paf-pas/*.zip
然后逐一清空日志文件
cat /dev/null > /opt/hikvision/web/components/tomcat85linux64.2/logs/paf-pas/paf.paf-pas.business.log
cat /dev/null > /opt/hikvision/web/components/tomcat85linux64.2/logs/paf-pas/paf.paf-pas.consumer.debug.log
cat /dev/null > /opt/hikvision/web/components/tomcat85linux64.2/logs/paf-pas/paf.paf-pas.debug.log
cat /dev/null > /opt/hikvision/web/components/tomcat85linux64.2/logs/paf-pas/paf.paf-pas.dts.log
cat /dev/null > /opt/hikvision/web/components/tomcat85linux64.2/logs/paf-pas/paf.paf-pas.error.log
cat /dev/null > /opt/hikvision/web/components/tomcat85linux64.2/logs/paf-pas/paf.paf-pas.other.log
cat /dev/null > /opt/hikvision/web/components/tomcat85linux64.2/logs/paf-pas/paf.paf-pas.runtime.debug.log
cat /dev/null > /opt/hikvision/web/components/tomcat85linux64.2/logs/paf-pas/paf.paf-pas.websocket.debug.log
换一个目录，跟上面一样的操作
先删除已归档的*.zip文件
rm -f /opt/hikvision/web/components/tomcat85linux64.2/logs/nms/*.zip
然后逐一清空日志文件
cat /dev/null > /opt/hikvision/web/components/tomcat85linux64.2/logs/nms/nms.nmsweb.business.log
cat /dev/null > /opt/hikvision/web/components/tomcat85linux64.2/logs/nms/nms.nmsweb.debug.log
cat /dev/null > /opt/hikvision/web/components/tomcat85linux64.2/logs/nms/nms.nmsweb.dts.log
cat /dev/null > /opt/hikvision/web/components/tomcat85linux64.2/logs/nms/nms.nmsweb.error.log
cat /dev/null > /opt/hikvision/web/components/tomcat85linux64.2/logs/nms/nms.nmsweb.ham.other.log
cat /dev/null > /opt/hikvision/web/components/tomcat85linux64.2/logs/nms/nms.nmsweb.other.log
cat /dev/null > /opt/hikvision/web/components/tomcat85linux64.2/logs/nms/nms.nmsweb.resourceStatus.other.log
cat /dev/null > /opt/hikvision/web/components/tomcat85linux64.2/logs/nms/nms.nmsweb.scheduled.other.log
cat /dev/null > /opt/hikvision/web/components/tomcat85linux64.2/logs/nms/nms.nmsweb.syncResource.other.log
其他目录里面文件都要，没有专门清理的价值
# du -sh /opt
106G /opt
# df -h
/dev/mapper/centos_hikvisionos-opt 119G107G 13G90% /opt
同理，清理tomcat85#1服务器
进入/reportservice/目录
先删除已归档的*.zip文件
rm -f /opt/hikvision/web/components/tomcat85linux64.1/logs/reportservice/*.zip
然后逐一清空日志文件
cat /dev/null > /opt/hikvision/web/components/tomcat85linux64.1/logs/reportservice/reportservice.reportservice.business.log
cat /dev/null > /opt/hikvision/web/components/tomcat85linux64.1/logs/reportservice/reportservice.reportservice.debug.log
cat /dev/null > /opt/hikvision/web/components/tomcat85linux64.1/logs/reportservice/reportservice.reportservice.dts.log
cat /dev/null > /opt/hikvision/web/components/tomcat85linux64.1/logs/reportservice/reportservice.reportservice.error.log
cat /dev/null > /opt/hikvision/web/components/tomcat85linux64.1/logs/reportservice/reportservice.reportservice.other.log
进入/eportal/目录
先删除已归档的*.zip文件
rm -f /opt/hikvision/web/components/tomcat85linux64.1/logs/eportal/*.zip
然后逐一清空日志文件目录
cat /dev/null > /opt/hikvision/web/components/tomcat85linux64.1/logs/eportal/eportal.portalserver.business.log
cat /dev/null > /opt/hikvision/web/components/tomcat85linux64.1/logs/eportal/eportal.portalserver.debug.log
cat /dev/null > /opt/hikvision/web/components/tomcat85linux64.1/logs/eportal/eportal.portalserver.dts.log
cat /dev/null > /opt/hikvision/web/components/tomcat85linux64.1/logs/eportal/eportal.portalserver.error.log
cat /dev/null > /opt/hikvision/web/components/tomcat85linux64.1/logs/eportal/eportal.portalserver.other.log
进入/ncgweb/目录
先删除已归档的*.zip文件
rm -f /opt/hikvision/web/components/tomcat85linux64.1/logs/ncgweb/*.zip
然后逐一清空日志文件目录
cat /dev/null > /opt/hikvision/web/components/tomcat85linux64.1/logs/ncgweb/ncg.ncgweb.business.log
cat /dev/null > /opt/hikvision/web/components/tomcat85linux64.1/logs/ncgweb/ncg.ncgweb.debug.log

cat /dev/null > /opt/hikvision/web/components/tomcat85linux64.1/logs/ncgweb/ncg.ncgweb.other.log
进入/sdmc/目录
先删除已归档的*.zip文件
rm -f /opt/hikvision/web/components/tomcat85linux64.1/logs/sdmc/*.zip
然后逐一清空日志文件目录
cat /dev/null > /opt/hikvision/web/components/tomcat85linux64.1/logs/sdmc/sdmc.sdmc.business.log
cat /dev/null > /opt/hikvision/web/components/tomcat85linux64.1/logs/sdmc/sdmc.sdmc.debug.log

扩容系统盘 /dev/vda 的第四个分区（即 /dev/vda4）因为其他分区不能动！
# growpart /dev/vda 4
CHANGED: partition=4 start=6295552 old: size=308277215 end=314572767 new: size=371191775 end=377487327
将待扩容的30GB空间，创建到一个新的分区中
fdisk /dev/vda
n 回车
回车 默认磁盘创建开始位置；
回车 默认磁盘创建结束位置；
t回车
回车 等同于输入默认分区的数目8
Hex code (type L to list all codes): 8e （表示LVM类型）

The partition table has been altered!

WARNING: Re-reading the partition table failed with error 16: Device or resource busy.
The kernel still uses the old table. The new table will be used at

上面这段文字，我的理解是需要重启一下才能生效。
