模拟LINUX磁盘分区有可用空间无可用Inodes时报错问题
1.创建测试脚本:[oracle@ocm1 ~]$ vi touchfile.sh #!/bin/bash for abc in {1..9} do touch /boot/test/$abc done "touchfile.sh" 5L, 66C written 2.创建测试目录、测试脚本[root@ocm1 oracle]# cd /boot [root@ocm1 boot]# mkdir test [root@ocm1 boot]# ls config-2.6.18-308.el5 symvers-2.6.32-300.10.1.el5uek.gz config-2.6.32-300.10.1.el5uek System.map-2.6.18-308.el5 grub System.map-2.6.32-300.10.1.el5uek initrd-2.6.18-308.el5.img test initrd-2.6.32-300.10.1.el5uek.img vmlinuz-2.6.18-308.el5 lost+found vmlinuz-2.6.32-300.10.1.el5uek symvers-2.6.18-308.el5.gz [root@ocm1 boot]# cd - /home/oracle [root@ocm1 oracle]# sh touchfile.sh [root@ocm1 oracle]# cd - /boot [root@ocm1 boot]# cd test [root@ocm1 test]# ls 1 2 3 4 5 6 7 8 9 3.查看当前/boot目录可用Inodes数量[root@ocm1 test]# df -i Filesystem Inodes IUsed IFree IUse% Mounted on 本栏目更多精彩内容:http://www.bianceng.cn/OS/Linux/ /dev/sda3 7318528 185460 7133068 3% / /dev/sda1 26104 50 26054 1% /boot tmpfs 128334 1 128333 1% /dev/shm 4.修改脚本,直接将可用Inodes用光[root@ocm1 boot]# cd /home/oracle/ [root@ocm1 oracle]# vi touchfile.sh #!/bin/bash for abc in {10..26110} do touch /boot/test/$abc done ~ "touchfile.sh" 5L, 71C written 5.执行脚本,脚本未执行完,即报错:No space left on device,事实上此时用df -h可以看到目录下有可用空间,可是因为没有Inodes,已经无法新建文件了,报错为:No space left on device [root@ocm1 oracle]# sh touchfile.sh [root@ocm1 oracle]# sh touchfile.sh touch: cannot touch `/boot/test/26064': No space left on device touch: cannot touch `/boot/test/26065': No space left on device ……………………………………………… touch: cannot touch `/boot/test/26109': No space left on device touch: cannot touch `/boot/test/26110': No space left on device [root@ocm1 oracle]# df -h Filesystem Size Used Avail Use% Mounted on /dev/sda3 28G 11G 15G 43% / /dev/sda1 99M 21M 73M 23% /boot tmpfs 502M 0 502M 0% /dev/shm [root@ocm1 oracle]# df -i Filesystem Inodes IUsed IFree IUse% Mounted on /dev/sda3 7318528 185460 7133068 3% / /dev/sda1 26104 26104 0 100% /boot tmpfs 128334 1 128333 1% /dev/shm 手动执行创建目录和文件命令报同样错误: [root@ocm1 oracle]# cd /boot/ [root@ocm1 boot]# mkdir a mkdir: cannot create directory `a': No space left on device [root@ocm1 boot]# touch abc touch: cannot touch `abc': No space left on device (编辑:常州站长网) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
