Let's assume I was very unlucky and ran out of inodes in my ext4 filesystem but left with enough free space.
Inode usage is 100%, but it has 50% disk free space.
How can I resolve it?

related: unix.stackexchange.com/questions/26598/… and precisely this comment: unix.stackexchange.com/questions/26598/… . Ratio can't be changed. But growing the filesystem will thus also increase inode capacity. As I guess you want this without growth, I'm just leaving a comment (it's probably a duplicate).A.B– A.B2024-03-04 17:34:11 +00:00Commented Mar 4, 2024 at 17:34

One option is to recreate your filesystem specifying bytes-to-inode ratio with -i option.
Backup all of your data to another disk.
List your filesystems and find the one you want to modify:
$ df -hassuming that filesystem is
/dev/sdXand is mounted on/mnt/mountpoint.Unmount that filesystem:
$ umount /mnt/mountpointCreate that filesystem using
mkfs.ext4command specifying-ibyte-to-inode ratio:$ mkfs.ext4 -i 4096 /dev/sdXThis command will create
ext4filesystem with 4 KB per inode ratio (which will create four times more inodes than the default value - 16 KB per inode).Mount that filesystem:
$ mount /dev/sdX /mnt/mountpoint

I don't understand the last requirement. What permissions might need to be applied that are only triggered during a reboot?Chris Davies– Chris Davies2024-03-05 10:01:21 +00:00Commented Mar 5, 2024 at 10:01

When rebooted, it will mount the filesystem as indicated in
/etc/fstabwith previous owner, group owner, umask permission, etc.firdavs– firdavs2024-03-05 10:46:41 +00:00Commented Mar 5, 2024 at 10:46 -
