anyone out here running ext4 - how is the experience? i hear frequent lockups if some files are being deleted in the background. I am planning to format one of my backup harddisks (either docking station 120gb hdd or one of my external backup 1TB hdd) to ext4. Does anyone think its worth it or should i just stick to ext3 for the backup hdds - they will mostly hold movie/music backups and a rare backup of my desktop documents (around 15000 files of few mb each!)

edit - here is one of the many links indicating lockups

If you're happy with the current filesystem, why bother changing? ext3 is good and stable, stick to it.

the current file system is ntfs on these external hdds. I'd rather trust ext4 over the reverse engineered ntfs-3g

I still don't understand the point of jumping on something new the moment it's out. Let others be the guinea pigs. Even disregarding all the problems that have been reported, you should always store your stuff on a tried and tested FS. And no, ext4 is still in its infancy.

To my knowledge, ext4 is just an upgraded version of ext3 with voulme size going in exa bytes and file size going in tera bytes. And I agree to the point that it is having some disadvantages.

According to me one of the best fs in terms of recovery in case of any issues or performace is ReiserFS.

Ext4 is not in its infancy now.there were some data losses issues.but ,from each new kernel releases ,it is going great.I am using 2.6.30 BTW.

Ext4 - Linux Kernel Newbies

btrfs is what is in its "infancy".

well guys - i moved all my external hdds to ext4 and yes performance is much much more. I did research and the 'delayed allocation feature causing data losses' has been fixed in jaunty itself. So far things are good - no slow downs or lock ups and performance is definitely improved.

has anyone here noticed that when you unmount an external hdd, it does not spin down and power off. This is irrespective of whether you do it from terminal or nautilus.

There are a some schools of thought around this being harmful to the hdds and people have some good ways of taking care of this
Unmounting external USB drives in Ubuntu 9.04 Sergei’s blog on bugs, penguins and stuff

most scripts will do a sync, unbind drivers and power down (i.e spin down) the drive.
Wonder how many of you feel this is necessary

^^ ok so i tried the script mentioned in the above linkie and it works like a charm (with usb and not firewire). I also modified it (as mentioned in the comments on the link) so that i can pass the mounted disk's name from the command line, as i use a lot of external hdds.
The hdds power down properly now (i.e. park their heads, spin down and led lights go off). Highly recommended to anyone out here who is concerned about unmounting safely :-)

Running Debian Sid (unstable) since past 5 years or more.

Used a basic install from Ubuntu, and then switched to Debian sid straightaway. (not recommended- you may end up trashing your system).

Six months back, found a spare hard disk. Used it to back up my partitions one by one, and converted partitions on my existing sata disk to ext4. All, except /boot/ since I am sticking to older grub. (At least grub2 is required if /boot is on an ext4 partition).

No problems so far.

I rebooted to the arch-linux partition on my PC today and found that the network is not coming up.

I tried starting it with "/etc/rc.d/network start", but I got error saying "eth0 unknown device :no such device".

The rc.conf is untouched since last time. I can see the network device when I run lspci. It is the Intel 82578DM Gigabit Ethernet PCI card.

How can it suddenly stop working?

Does 'dmesg' show some error about initialization?
I assume that you have a dual boot configuration and switched from Windows to Linux after a reboot. If so, did you try a power down and power up - straight to Linux?

Samurai, as lobsterB points out, it could be that the network card is not detected, or is assigned as something else other than eth0 (like eth1).

What are contents of the /proc/net/dev file?
