Because the original installation system design is unreasonable, some zoning is too small, as well as network communication failures and other causes of log file speed growth and other reasons can be displayed as disk space full, resulting in the inability to read and write the disk, the application can not execute. Here are a few tips for you (take/home space full as an example):
1. Regular scanning of important file systems, and comparison, analysis of those documents often read and write
#IS-ir/home>;files.txt
#diff Filesold.txt Files.txt
By analyzing the growth of the predicted space, you can also consider compressing the infrequently read and write files to reduce space usage.
2. View the inodes consumption of the space file system
#df-i/home
If there are a large number of inpde available, indicating that large files occupy space, no thief may be a large number of small files occupy space.
3. Find a large footprint directory
View space occupied by/home
#du-hs/home
View footprint over 1000m under/home
#du/awk ' $1>;2000 '
4. Find a document that occupies a larger space
#find/home-size +2000k
5. Find the most recently modified or created file
First touch a file with the time you want as follows
#TOUCH-T 08190800 Test
#find/home-newer Test-print
Delete Log
#rm-rf/var/log/*
7. Make connections to partitions
In a space partition, make a connection to an empty partition
#in-s/home/use/home
8. Find a process that consumes a lot of space
According to the different application, find the corresponding process, analyze the reason.
9. Check and Repair file system
#fsck-y/home
10. Reboot the Machine
With the above 10 strokes, you should be able to solve most of the problems, but the key is to plan the partition when installing. Also found that the disk is quite, not urgent, careful operation, serious analysis of the reasons, and then carefully deal with. Need to note that the above ten strokes do not need sequential execution, some may be a recruit seal throat, some may need to use several strokes, delete operation must be careful. If not, only to take the additional hard drive, reinstall the system and other "hard" way
It's OK:
cd/
Du-h--max-depth=q/grep M/sort-n
Find the largest directory and enter the directory
Run Du-h-max-depth=1/grep M/sort-n again
Find out if it's a useful file after you look it up
Delete it if it doesn't work.
