Run out of inodes how to solve the problem?

Question

linux

How to find out in which folder the most files have accumulated? tmp folder is empty

Answer 1

Before doing anything, you need to make sure that the problem is with inodes.
Use the command:

[alexsystem ~]# df -i
Filesystem            Inodes   IUsed   IFree IUse% Mounted on
/dev/hda2            121896960  227651 121669309    1% /
/dev/hda1              26104      44   26060    1% /boot
tmpfs                  64417       1   64416    1% /dev/shm

The values ​​IUsed, IFree, IUse% will give you an idea on which file system (partition) you have a problem.
Then you need to see which folder has the most nested items (files and folders), and then display them in a list, sort the list in ascending order, use this pipeline:
mindepth 2 or 3 because it is enough to view/count files in folders of 2/3 nesting levels. tail -10 means the top 10 folders with the most items will be shown.
In fact, when everything is done correctly in the system, then such a problem as a lack of inodes does not arise.
At a minimum, this confirms my experience of using SCO UNIX 3.2v4.2 in an industrial enterprise, SCO Open Desktop 3, OpenServer 5 in a bank for the banking system, RedHat Linux, CentOS in various "dispatching" (call centers). There were no problems with inodes.
