Ext4 filsystemet

Indlægaf lath » 12. mar 2009, 23:17

Fra Ext4fs Wikien fra kernel.org kan det læses at ext4fs kan installeres i Ubuntu Hardy Heron (8.04) ved at bruge en mindre mængde pakke (kun i386 platform), og i Ubuntuer senere end Hardy med patches (rettelser):

Fra http://ext4.wiki.kernel.org/index.php/Ext4_Howto#For_people_who_are_running_Ubuntu:
For people who are running Ubuntu, it is *highly* recommended that you download a set of modified util-linux packages and install them. Packages for Ubuntu Hardy are available here: ftp://ftp.kernel.org/pub/linux/kernel/people/tytso/ubuntu-fixed-util-linux. These packages revert a change made by Ubuntu: http://changelogs.ubuntu.com/changelogs/pool/main/u/util-linux/util-linux_2.12r-19ubuntu1/changelog to use the volid library instead of the blkid library. The volid library has a number of shortcomings, including that they don't work on freshly created filesystems or swap devices until after you reboot (since it is tied to udev probing) and the volid library doesn't understand ext4dev filesystems. The blkid library is much better, and Debian uses the blkid library for util-linux. Unfortunately, Ubuntu chose to make this reason for some unknown reason. For other versions of Ubuntu, the patch that was applied can be found here: ftp://ftp.kernel.org/pub/linux/kernel/people/tytso/ubuntu-fixed-util-linux/util-linux-patch. Update: From 9 January daily builds: http://cdimage.ubuntu.com/daily/current/ of Jaunty will include ext4 as a partitioning option. As far as I can tell, it installs and boots fine (including full ext4 /; you don't need a separate /boot). Here is the announcement, It will be included in 9.04 and maybe it will be by default option in 9.10: http://brainstorm.ubuntu.com/idea/16854/
