I have tested full reiserfs file check and 640GB has been checked in 20mins and this check is not necessary. It is a good job in comparison with ext2 where 20GB check spends 2 hours. But I still believe that there must be some dependency between allocation units and wasted space. I guess that one allocation unit could accommodate one short file but looking here: http://homes.cerias.purdue.edu/~florian/reiser/reiserfs.php it does not neccesary to be a case. thanks for explanation Jara > > - -Jeff > > - -- > Jeff Mahoney > SUSE Labs > -----BEGIN PGP SIGNATURE----- > Version: GnuPG v2.0.9 (GNU/Linux) > Comment: Using GnuPG with SUSE - http://enigmail.mozdev.org > > iEYEARECAAYFAkl3dqQACgkQLPWxlyuTD7KOdwCgoPs3UxgdETHZ5p4D/czIqV1I > Jr4AoIA6QFySoLr5OaRsHawTbTD4GDzd > =HRr2 > -----END PGP SIGNATURE----- -- To unsubscribe from this list: send the line "unsubscribe reiserfs-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
