It would also be good to distinguish between directories referencing

I'd think it needs a "chunk space" number and a 32 bit loc

Hi,
The tool estimates the cross-chunk references from an extt2/3 file
system. It considers a block group as one chunk and calcuates how many
block groups does a file span across. So, the block group size gives
the estimate of chunk size.
The file systems were aged for about 3-4 months on a deve

Nice to see some numbers! But would be really nice to know:
- what the chunk size is
- how the files were created or, more vagu
Hi,
The attached code contains program to estimate the cross-chunk
references for ChunkFS file system (idea from Valh). Below are the
results:

Number of files = 217806
Number of directories = 24295
Total size = 8193116 KB
Total data stored = 7557892 K
