Simulate Linux disk partitions have free space available inodes times wrong problem

1. Create a test script:

[Oracle@ocm1 ~]$ VI touchfile.sh

#!/bin/bash

For ABC in {1..9}

Todo

touch/boot/test/$ABC

Done

"Touchfile.sh" 5L, 66C written

2. Create test directories, test scripts

[Root@ocm1 oracle]# Cd/boot

[ROOT@OCM1 boot]# mkdir Test

[ROOT@OCM1 boot]# ls

Config-2.6.18-308.el5 symvers-2.6.32-300.10.1.el5uek.gz

Config-2.6.32-300.10.1.el5uek System.map-2.6.18-308.el5

Grub System.map-2.6.32-300.10.1.el5uek

INITRD-2.6.18-308.EL5.IMG Test

Initrd-2.6.32-300.10.1.el5uek.img Vmlinuz-2.6.18-308.el5

Lost+found Vmlinuz-2.6.32-300.10.1.el5uek

Symvers-2.6.18-308.el5.gz

[ROOT@OCM1 boot]# CD-

/home/oracle

[ROOT@OCM1 oracle]# SH touchfile.sh

[ROOT@OCM1 oracle]# CD-

/boot

[ROOT@OCM1 boot]# CD test

[ROOT@OCM1 test]# ls

1 2 3 4 5 6 7 8 9

3. View the number of inodes available in the current/boot directory

[Root@ocm1 test]# Df-i

FileSystem inodes iused ifree iuse% mounted on

This column more highlights: http://www.bianceng.cnhttp://www.bianceng.cn/OS/Linux/

/dev/sda3 7318528 185460 7133068 3%/

/DEV/SDA1 26104 26054 1%/boot

TMPFS 128334 1 128333 1%/DEV/SHM

4. Modify the script, directly use Inodes

[Root@ocm1 boot]# cd/home/oracle/

[Root@ocm1 oracle]# VI touchfile.sh

#!/bin/bash

For ABC in {10..26110}

Todo

touch/boot/test/$ABC

Done

~

"Touchfile.sh" 5L, 71C written

5. Execute the script, the script is not finished, that is, error: No space left on device,

In fact at this time with DF-H can see the directory there is free space, but because there is no inodes, can not create a new file, the error is: No spaces left on device

[ROOT@OCM1 oracle]# SH touchfile.sh

[ROOT@OCM1 oracle]# SH touchfile.sh

Touch:cannot Touch '/boot/test/26064 ': No spaces left on device

Touch:cannot Touch '/boot/test/26065 ': No spaces left on device

......................................................

Touch:cannot Touch '/boot/test/26109 ': No spaces left on device

Touch:cannot Touch '/boot/test/26110 ': No spaces left on device

[Root@ocm1 oracle]# Df-h

Manual execution of the Create directory and File command reported the same error:

[Root@ocm1 oracle]# cd/boot/

[Root@ocm1 boot]# mkdir A

Mkdir:cannot Create directory ' a ': No spaces left on device

[ROOT@OCM1 boot]# Touch ABC

Touch:cannot Touch ' abc ': No spaces left on device
