 |
|
Hey all,
I have a /media partition that was originally optimized for large media files (movies, mythtv storage,etc). When I created it, I must have used an option that minimized the number of inodes. For example, my root vs my media drive:
| Code: | Filesystem Inodes IUsed IFree IUse% Mounted on
/dev/sda3 1251712 397363 854349 32% /
/dev/mapper/main-media 64000 55616 8384 87% /media |
Now I sometimes will run out of inodes. I would like to be able to figure out which directories on my media partition use the most inodes so that I can create a more optimized partition for them.
Thanks! |

| Each file on disk requires an inode. Assuming you do not create extra hard links to files, you can find where your inodes are used by looking at where you have files and directories. If you create extra hard links, then counting becomes more complicated, since you have multiple directory entries for a single inode. |

This will give you an overview of which directories contain the most files:
| Code: | cd /media
find . -maxdepth 2 -type d ! -name '.' | while read dir; do
printf "%6d\t%s\n" $(ls -R "$dir" | wc -l) "${dir:2}"
done | sort -n |
Adjust the maxdepth argument for more or less detail.
