CENTOS 磁盘占用100%（20G）但是文件系统只占用了1.8G，到底什么原因导致的

Question

Filesystem Size Used Avail Use% Mounted on
/dev/xvda1 20G 19G 4.0K 100% /
tmpfs 938M 0 938M 0% /dev/shm
/dev/xvdb1 20G 173M 19G 1% /pan2

我用du -h --max-depth=1 / 查看所有文件只占用了1.8G。到底什么原因导致的磁盘100%？

Answer 1

df -lh 查看磁盘用量
df -i 查看inode用量
du -sh |*sort -n View folder size

After cleaning the disk, you find that the capacity has not been reduced, then reboot

Answer 2

Not enough inode nodes

Answer 3

You can use lsof -a | grep delete to check. It may be that some files are not really deleted. Just kill pid.

Note: Root is required

Answer 4

May I ask if the poster has any solution? I am in the same situation as you.

Answer 5

Execute resize2fs /dev/xvda1
