    Re: EXT4 - I just don't get it.

    On Ext4 you WILL have a roughy 99% chance of losing data when the power goes.
    Say what you want, but I doubt the bug is still fixed
    When the power plug goes, so does lots of data.
    The problem is that you lose such a ridicules amount of data in contrast to other filesystems.
    Which in essence makes it a really really poor file system.
    I guess we could add it to the pile of "its broken, but since it only affect the desktop, we will not fix it".
    Xorg is a part of that pile, ATI is starting to get of that pile(doing a quite good job), GIMP and GTK is a part of that pile, and more, schedule in Linux is still a part of that pile.

    I live in California, ergo, I lose power all the time and never once have I lost data on my ext4 partitions over the years on systems both with and without power conditioning. Not even on brown outs which are far more dangerous to electronics than losing power. Take a statistics class.

    EXT4 is fine for the average home user.

    This is true of ANY filesystem. It is not a bug, it is called the disk cache. Writes remain in ram for a while before being written to the disk, and if you lose power before they reach the disk, then you obviously lose that data.

    No, you don't; you lose only what you wrote in the seconds before the power went out.

    You mean a slow fs implemented in userspace that is fundamentally broken ( it fails horribly under load testing )?

    I am sure ZFS it is not THAT utterly broken. Why all that aggression?

    Regardless this thread convinced me to switch back to ext4, my main issue is slower dpkg and databases though I think I deal with it.

    Re: EXT4 - I just don't get it.

    I thought that ZFS on linux was not possible due to licensing reasons?

    EDIT: I mean having ZFS ported directly the Linux.

    Re: EXT4 - I just don't get it.

    This thread has gotten a bit out of control in regards to the topic. I have my answers, I know where I'm headed, so I'm marking the thread as solved.

    I'm going to give EXT4 a try again and see what happens, maybe I messed something up, but I doubt it.

    Anyways, thanks for all your input everyone. I still really like XFS and Reiser4 - although Reiser4 I couldn't make it my / root filesystem, it was still awesome to get transfer rates faster than a Lamborghini driving at 100 mph (160.93 kph)
