Hi, I've installed a few Fedora Core 4 and Fedora Core 5 recently, and found that the new ext3 file systems created with new mkfs.ext3(1.38+) has one more field than EXT3 created with old mkfs.ext3(1.34-), even the latter's dir_index feature was turned on and file systems were upgraded with "e2fsck -y -f -D" command. I have three questions thereafter: 1) what does the "Reserved GDT blocks" mean? and what are its functions and purposes? 2) for file systems created with older versions of mkfs.ext3(v1.34-) on FC1, how to upgrade it to the newest version? I manually turned on dir_index(which is by default OFF for 1.34-, but by default ON on 1.38+) with command "tune2fs -O dir_index", then run command "e2fsck -y -f -D" to upgrade it (e2fsck is 1.38+). If the above upgrade way is the "official" way? If not, then what is the prefered way to upgrade old ext3 file system to be used on FC4/FC5? 3) are there any other difference besides "Reserved GDT blocks" between newly created ext3 file systems and upgraded ones by e2fsck? Please help. Thanks a lot. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
