Problem: Insufficient Inode capacity (refer to the inode number of bytes and the number of blocks)
inode number is not infinite, if a partition of nodes to be used over, even if there is a surplus of disk space can no longer store any data
Query bytes occupancy: df -i (where i refers to the inode)
Example:
Problem: / fdik utilization rate of three percent Why not create a file?
Conclusion: Each file or directory inode has a corresponding number of bytes of capacity, lack of capacity once the number of bytes, you can not create a file
[fdik the root @ localhost] # Touch. 1} {R & lt
Touch: Can not create "r {1}": no space on the device
[fdik the root @ localhost] # DF -i

Workaround: Clear the number of bytes for the files to free up space size 0
[Root @ localhost ~] # find / fdik -size 0 // Check / fdik the file size in bytes 0
[root@localhost ~]# sudo find /fdik/ -type f -size 0 -exec rm {} \; //删除
[root @ localhost ~] # df -i
