1. Linux服务器磁盘经常占满,使用命令df -h查看哪些磁盘被占满了
df -h
Filesystem Size Used Avail Use% Mounted on
/dev/vda2 35G 34G 1G 98% /
devtmpfs 16G 0 16G 0% /dev
tmpfs 16G 12K 16G 1% /dev/shm
tmpfs 16G 1.6G 15G 11% /run
tmpfs 16G 0 16G 0% /sys/fs/cgroup
/dev/vda1 477M 92M 356M 21% /boot
/dev/vdb1 197G 171G 16G 92% /data
tmpfs 3.2G 0 3.2G 0% /run/user/1064
tmpfs 3.2G 0 3.2G 0% /run/user/0
tmpfs 3.2G 0 3.2G 0% /run/user/1061
tmpfs 3.2G 0 3.2G 0% /run/user/1000从上面看/dev/vda2占用98%,这个磁盘指的是Linux除下面所有磁盘中剩余的磁盘空间， 主要的有 /usr /home /opt等
比如/usr可以cd 到该目录，看下占用空间
du -sh 查看总文件夹的大小
du -sh * 查看当前目录下所有文件夹占用大小
[root@a...usr]# du -sh
1.6G .[root@alta1-web-1 usr]# du -sh *
100M bin
4.0K etc
4.0K games
22M include
316M java
379M lib
152M lib64
62M libexec
124M local
40M sbin
337M share
67M src
0 tmp使用 du -sh * | sort -nr | head 查看占用空间最大的
不过有时候占用空间其实并不大， 但是地df -h显示占用空间很大，绝大多数原因是
此服务器上有写日志的操作，在写的同时把要写入的文件删除了。。因为在写操作不能创建文件的时候会写硬盘的block，这样会使硬盘利用率越来越低，可以使用lsof -n |grep delete 来查看哪些进程在对磁盘进行写操作。
一般都是程序打开了已经删除的文件，导致磁盘未释放该文件。lsof|grep delete之后kill掉该进程，或者直接重启
[root@alta1-tools-web-1 /]# lsof -n |grep delete
