Re: Thoughts about EXT4 optional in Jaunty Development questions about Plymouth
To be clear, and as I'm sure you already know, you will not benefit from EXT4's advanced layout functionality for existing files if you convert. Only new files will be created with extents and the rest of the advanced features.

Yes, as the end of http://ext4.wiki.kernel.org/index.php/Ext4_Howto says: To convert an existing ext3 filesystem to use ext4, use the command $ tune2fs -O extents,uninit_bg,dir_index /dev/DEV WARNING: Once you run this command, the filesystem will no longer be mountable using the ext3 filesystem! After running this command, you MUST run fsck: $ fsck -pf /dev/DEV NOTE: by doing so, new files will be created in extents format, but this will not convert existing files. However, they can be transparently read by Ext4. WARNING: It is NOT recommended to resize the inodes using resize2fs, as this is known to corrupt some filesystems. -- Colin Watson [cjwat...@ubuntu.com] -- Ubuntu-devel-discuss mailing list Ubuntu-devel-discuss@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel-discuss

I'm using it for my 2 data hard drives which were originally ext3. But ext4 is backward compatible and therefore has the capability to mount ext3 partitions and ext4. Here's what I done (as I posted in a recent forum): First you have to enable the system to mount ext4 because Ubuntu still flags ext4 file system as experimental as is therefore disabled by default. ubuntu% sudo tune2fs -E test_fs /dev/your_drive_partition And then you simply have to mount the drive. ubuntu% sudo mount /dev/your_drive_partition -t ext4dev /media/your_mount_directory Done. A quick check with df to see if it worked. ubuntu% df -T It worked. Here's what mine looks like. The last 2 entries are the ext4 mounts. You'll notice that they are flagged as ext4dev, that's because (as mentioned) Ubuntu still flags ext4 as experimental, even though it's not. ubuntu% df -T Filesystem Type 1K-blocks Used Available Use% Mounted on /dev/sda6 jfs17549600 4258296 13291304 25% / tmpfstmpfs 250364 0250364 0% /lib/init/rw varrun tmpfs 250364 324250040 1% /var/run varlock tmpfs 250364 0250364 0% /var/lock udev tmpfs 250364 2872247492 2% /dev tmpfstmpfs 250364 0250364 0% /dev/shm lrm tmpfs 250364 2380247984 1% /lib/modules/2.6.27-7-generic/volatile /dev/sda1 jfs 495712 13176482536 3% /boot /dev/sda5 ext255599836 25436932 27903524 48% /home /dev/sdb1 ext4dev 157566568 45810908 103751680 31% /home/chris/disk /dev/sdc1 ext4dev 307663800 256501836 35778776 88% /home/chris/disk-1 For the record too, it's definitely snappier with both read/write on the simple real world tests that I done.
