Hello All, I'd like to know if there is an utility like `Filefrag' shipped with e2fsprogs on linux, which is used to fetch the extents mapping info of a file(especially a sparse file) located on ZFS?
I am working on efficient sparse file detection and backup through lseek(SEEK_DATA/SEEK_HOLE) on ZFS, and I need to verify the result by comparing the original sparse file and the copied file, so if there is such a tool available, it can be used to analyze the start offset and length of each data extent. Thanks in advance! -Jeff _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
