Excellent. Ext4 has been pretty stable in recent months and anyway Fedora is 'sposed to tolerate more than a little instability. F10 might have been a little early for an ext4 default but F12 is too slow for a bleeding edge distro .... yeah - feels right.

i hear Ubuntu will have ext4 as default in 9.10

I've been using ext4 on my /home for quite a while (IIRC it's since when e2fsprogs began to support ext4). Haven't experienced setbacks

what differences do you notice in ext4 compared to ext3? i know its supposed to be faster but anything else apart from that?

how are you formating your disks to ext4?

gparted 3.9 does not have an option to format to ext4....

Actually I can hardly notice anything...

Beginning from version 1.41(? IIRC), the e2fsprogs package has ext4 support built in. There's a tool "mkfs.ext4", which is a frontend of mke2fs. You can also call mke2fs directly with "-t ext4".

Slow operations are slow as usual so I don't notice. Fast operations are already very fast so again I don't notice

just kidding ... In my experience quotacheck seems to be much faster with ext4.

well thats good . iv'e never used it so i personally dont know the speed difference's with it yet but thats good to know that

I've been using the experimental ext4 too. Formatted by doing clean installs each time. Only "downside" is having to keep an ext3 partition for /boot. Oh - and my performance monitoring tool only monitored the capacity usage of devices of type ext3 :-o

Didn't benchmark anything before going with it, so I couldn't say if it performs any faster. What I can say is that it's been as robust as necessary on a server, desktop, laptop and several KVM guests. The KVM guests especially get trashed about (power resets during operations etc - I generally don't "care" about them as I can recreate them quickly enough). I've not had any issues with corrupt disks etc.

Looking forward to it becoming the default in Fedora - with a patch to grub to allow /boot to be ext4 as well :-)

Cheers

This is one of the intended benefits along with the improvements against loss of data when a hard crash (ie power cut) happens, and improvements to disk-write to minimise things like fragmentation (which isn't a problem for most people anyway)

ext4 is meant to be more data tolerant, and not all of the speed ups are things people would/should notice
