They were created via CIFS. I thought sparse files were an iSCSI concept,
no?
Sparse files are a traditional Unix filesystem feature. Many/most
database files are sparse. All that is needed to create a sparse
portion of a file is to seek beyond the current end of the file and
write something. The ftruncate() function may be used to create
all/part of a file which is sparse. A smart file writer (or the
filesystem) could easily convert long blocks of zero to a sparse
allocation.
