Hi. While doing a scan of disk usage, I noticed the following oddity.
I have a directory of files (named file.dat for this example) that all
appear as ~1.5GB when using 'ls -l', but that (correctly) appear as
~250KB
files when using 'ls -s' or du commands:
These are probably just sparse files. Nothing to be alarmed about.
They were created via CIFS. I thought sparse files were an iSCSI
concept, no?
iSCSI is a block level protocol. Sparse files are a filesystem level
concept that is understood my many filesystems including CIFS and ZFS
and many others.
Yea, kept googling and it makes sense. I guess I am simply surprised
that the application would have done the seek+write combination, since
on NTFS (which doesn't support sparse) these would have been real
1.5GB files, and there would be hundreds or thousands of them in
normal usage.
thx!
