” хубаво, но няма да можем да минем тънко (само с ъпдейт) :(
тоест - ще трябва наново преинстал за да ползваме новата файлова система :( лоша работа „
;) има начини споко...ще му дойде и на това времето...не му мисли...то и сега можеш да мигрираш в EXT4.Както и да е има време ;) очертава се да е една от най-стабилните.

"3. How to use Ext4
This is the first stable version of Ext4, so even if the whole development and release of this filesystems has been slowed down and delayed a lot to guarantee the same level of stability that you'd expect from the current Ext3 implementation, the usual rules of any ".0" software apply.
One very important thing to keep in mind is that there is NOT Ext4 GRUB support. Well, that wasn't exactly true: There is grub support, but it's not very spread in the currently available distros. There's ext4 support in the GRUB2 development branch, but since GRUB2 is not stable, most of distros are using the 0.9x versions.
There are available grub2 packages in Ubuntu and debian-derived distros as the grub-pc package. In the 0.9x branch, there's not official support, but there's a Google SoC project that developed support for it, and Google finds patches. So choose yourself. The next release of distros based in Linux 2.6.28 will probably have support in one way or another. The safe option is to keep your /boot directory in a partition formatted with Ext3.
You also need an updated e2fsprogs tool, of course, the latest stable version -1.41.3- is recommended.
NOTE: At least in debian-derived distros, including Ubuntu, converting your filesystem to Ext4 when using a initramfs results into a non-booting system, apparently even when you enable the "ext4dev compatibility" option". The problem is that the fstype klibc utility detects the ext4 filesystem as ext3, and tries to mount it as ext3, and fails. The fix is to pass the "rootfstype=ext4" option (without the quotes) in the kernel command line.
Switching to Ext4 it's very easy. There are three different ways you can use to switch:
3.1. Creating a new Ext4 filesystem from the scratch
*The easiest one, recommended for new installations. Just update your e2fsprogs package to Ext4, and create the filesystem with mkfs.ext4.
3.2. Migrate existing Ext3 filesystems to Ext4
You need to use the tune2fs and fsck tools in the filesystem, and that filesystem needs to be unmounted. Run:
*tune2fs -O extents,uninit_bg,dir_index /dev/yourfilesystem
After running this command you MUST run fsck. If you don't do it, Ext4 WILL NOT MOUNT your filesystem. This fsck run is needed to return the filesystem to a consistent state. It WILL tell you that it finds checksum errors in the group descriptors - it's expected, and it's exactly what it needs to be rebuilt to be able to mount it as Ext4, so don't get surprised by them. Since each time it finds one of those errors it asks you what to do, always say YES. If you don't want to be asked, add the "-p" parameter to the fsck command, it means "automatic repair":
*fsck -pf /dev/yourfilesystem
There's another thing that must be mentioned. All your existing files will continue using the old indirect mapping to map all the blocks of data. The online defrag tool will be able to migrate each one of those files to a extent format (using a ioctl that tells the filesystem to rewrite the file with the extent format; you can use it safely while you're using the filesystem normally)
3.3. Mount an existing Ext3 filesystem with Ext4 without changing the format
You can mount an existing Ext3 filesystem with Ext4 but without using features that change the disk format. This means you will be able to mount your filesystem with Ext3 again. You can mount an existing Ext3 filesystem with "mount -t ext4 /dev/yourpartition /mnt". Doing this without having done the conversion process described in the previous point will force Ext4 to not use the features that change the disk format, such as extents, it will use only the features that don't change the file format, such as mballoc or delayed allocation. You'll be able to mount your filesystem as Ext3 again. But obviously you'll be losing the advantages of the Ext4 features that don't get used..."
