1.查看磁盘具体占用情况
[root@localhost gsidc]# df -hT
Filesystem Type Size Used Avail Use% Mounted on
/dev/sda3 xfs 92G 21G 72G 23% /
devtmpfs devtmpfs 7.8G 0 7.8G 0% /dev
tmpfs tmpfs 7.8G 0 7.8G 0% /dev/shm
tmpfs tmpfs 7.8G 129M 7.7G 2% /run
tmpfs tmpfs 7.8G 0 7.8G 0% /sys/fs/cgroup
/dev/sda1 xfs 197M 192M 5.0M 98% /boot
tmpfs tmpfs 1.6G 12K 1.6G 1% /run/user/42
tmpfs tmpfs 1.6G 0 1.6G 0% /run/user/1000
2.删除具体位置磁盘占用无用文件
3. 查看磁盘删除情况
[root@localhost gsidc]# lsof |grep delete
4. 彻底释放磁盘空间
mysqld_sa 11317 root cwd DIR 8,6 0 102107 /usr/local/mysql (deleted)

关闭删除文件进程
[root@localhost /]# kill -9 16961
磁盘容量恢复
