-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I read from manual and source code, it seems fragment size should be same to filesystem block size. Therefore, can I say current ext3/4 filesystem still do not support fragment ? Thanks. Coly Andreas Dilger wrote:

These days, when I read the source code of mke2fs, I found an option -f to set the fragment size. But I can not find any explaining for ext3/4 framgment from google, excepting someone saying ext2/3 does not support this feature. Can anyone tell me what is the function or purpose of fragment of ext file system ?This is an obsolete concept from BSD that was never used by ext[234]. Consider a "fragment" in this context to be the same as a "tail" for reiserfs. A very small file, or the end of a file that is less than a block.
