why Inode file size is different than actual size

Question

I noticed one log file having less size than what's mentioned in inode.

$ ls -lhtr /var/log/test/fk-3p-kafka/kafkaServer-gc.log
-rw-r--r-- 1 fk-3p-kafka fk-3p 11G Apr 10 18:27 /var/log/test/fk-3p-kafka/kafkaServer-gc.log
$ du -sh /var/log/test/fk-3p-kafka/kafkaServer-gc.log
2.4G    /var/log/test/fk-3p-kafka/kafkaServer-gc.log
$# stat /var/log/test/fk-3p-kafka/kafkaServer-gc.log
  File: `/var/log/test/fk-3p-kafka/kafkaServer-gc.log'

Next thing I did was to check for any deleted file handlers.

Clearly there were no deleted FD for kafkaServer-gc.log. I tried truncating the file too but file size in inode is not changing. What could be the reason for this behaviour?

Use filefrag -v /var/log/test/fk-3p-kafka/kafkaServer-gc.log to see how the file is laid out on disk. It's probably highly fragmented, giving an extremely long and impenetrable filefrag report, but it will be obvious in the first few lines if the first block's offset is ~9 gigs in. — Matt Nordhoff, Apr 11 '16 at 03:42

Given that this is a log file, here's the most likely explanation:

There is a process that has the file open and keeps appending to it. Currently that's process 22252, there may have been other processes in the past (previous instances of the same application).
At some point in the past, someone truncated the file. Truncating the file to a certain position removes all the data past that position, but it doesn't affect the position of a process that's appending to a file.

Let's say the file was truncated to position 0. Then, immediately after the truncation operation, the file size was 0. But the Java process had the file open, and had its current position set to n. The next time the Java process wrote to the log file, it wrote from position n to n + k (where k is the number of bytes that it wrote), so after this point the file size was n + k, and it continued growing as the Java process wrote more.

The disk usage¹ is less than the file size because the truncation deleted all the storage used for the file content. When the process appended to the file after the truncation, that turned the file into a sparse file: all bytes before position n are null bytes, but blocks consisting entirely of null bytes are not re-created. Let's say that n = 1024567 and the block size is 1024 bytes, then on the first append operation after truncation, a block for positions 1024000–1025023 was created, with 567 null bytes followed by the k bytes of that log message.

Deleting a file that's still open wouldn't affect either its disk usage or its file size, but it would make the file invisible to du and ls while still occupying space that's recorded as in use by df. See Why are there so many different ways to measure disk usage?

¹ _{The number of blocks used by the file — both it and the file size are stored in the inode, so don't call the disk usage “inode file size”!}

It's probably a sparse file, i.e. a file that is largely empty, and where not all the disc blocks needed for the full size have been allocated.

Using dd if=/dev/zero bs=1 count=1 seek=1E of=sparse I just made a file with an apparent size of 1 EB and I don't have that much disc space:

grove@cassiopeia> ls -lh sparse  
-rw-r--r-- 1 grove grove 1.1E Apr 10 23:53 sparse
