Did I hit the max inode limit?
Had some fun testing the limits of Linux filesystem (All non-pseudo partitions are ext4). Here is what is did, separated into sections of code for easier interpretation:
Code:
[root@scarecrow mystuffz]# mkdir -p /tmp/mystuffz
[root@scarecrow mystuffz]# cd /tmp/mystuffz
[root@scarecrow mystuffz]# for i in $(seq 1 3000000); do touch file$i.{txt,dat,log}; done
touch: cannot touch `file217120.txt': No space left on device
touch: cannot touch `file217120.dat': No space left on device
touch: cannot touch `file217120.log': No space left on device
touch: cannot touch `file217121.txt': No space left on device
touch: cannot touch `file217121.dat': No space left on device
^C
But there is ample space left:
Code:
[root@scarecrow mystuffz]# df -h

/dev/mapper/vg_main-lv_tmp

12G 763M 11G 7% /var/tmp
/dev/mapper/vg_main-lv_home
25G 7.9G 16G 34% /home
OK, let's create another file in this /tmp partition:
Code:
[root@scarecrow mystuffz]# cd ..
[root@scarecrow tmp]# touch file
touch: cannot touch `file': No space left on device
[root@scarecrow tmp]# echo $?
1
Let's try creating a file in another partition:
Code:
[root@scarecrow tmp]# cd ~
[root@scarecrow ~]# touch file
[root@scarecrow ~]# echo $?
0
So, did I hit the inode limit for /tmp partition? |
