I am checking a file system (ext3) as shown below. It is actually a fresh file
system, as I had deleted all partitions and created an ext3 file system. But
when I run the check with the verbose option, it says I have one large file.
Am I missing something here, or is it odd that I cannot find this large file it
is reporting? I reviewed some documentation on ext3 file systems, and
experimented with different sizes and formats, but finally decided to post
(after reviewing archives). Is this "large file" just a private file used by
the file system itself, or maybe the journal? It is a large drive (500GB), so
maybe a large file got generated which normally might appear smaller on a
smaller drive.
I tried ls -sal and other flags with ls looking for the large file. I also ran
dump2fs, although the output can be somewhat complex.
I included the beginning of the dump2efs output below my fsck.ext3 output.
Thanks,
Edmond
