Check disk space with df -h, it shows 129 GB disk space is free

This can be due to inodes getting full, check inodes usage with “df -i”.

As you can use Inodes are all used up.
To find where inodes are used up, run
|
1 |
find / -xdev -printf '%h\n' | sort | uniq -c | sort -k 1 -n |
If you have recent version of du, you can use
|
1 |
du --inodes -xS | sort -n |
This will display all folders with inode usage, sorted by inode usage.
