Get fsync() failed: Disk quota exceeded on the linux machine

I get fsync() failed: Disk quota exceeded, but when I use df -h and df -i there is enough space? Any suggestions?

The disk quota is a limit on the disk space that a user can occupy. It has nothing to do with free space on disk. Look at the manual page for quota(1). So when trying to sync (write out data held in memory destined to files on disk) it finds that you aren't allowed to write that much data.

And BTW, there is no "space in folders" in Unix/Linux. A directory is just an association between names and inodes, and an inode represents a file/directory (with its owner/group, permissions, and contained data). An inode can very well be listed in more than one directory, or even several times under different names in the same directory.

I don't really know, why the commands you mentioned would fail, but you could try

> wordlist.txt

This tells the shell to truncate the file to 0 length without spawning another process.

As noted in the comments: it seems likely that you're over quota, and the filesystem is rejecting your write for this reason.

There are many filesystems where all writes are journaled, with the old version kept. One such filesystem is ZFS - read about the interaction between ZFS snapshots and quotas.

(However, the problem may just be that the NFS server rejects all writes when you're over quota).
