Is ext4 Stable For Production Systems? 289

dr_dracula writes "Earlier this year, the ext4 filesystem was accepted into the Linux kernel. Shortly thereafter, it was discovered that some applications, such as KDE, were at risk of losing files when used on top of ext4. This was diagnosed as a rift between the design of the ext4 filesystem and the design of applications running on top of ext4. The crux of the problem was that applications were relying on ext3-specific behavior for flushing data to disk, which ext4 was not following. Recent kernel releases include patches to address these issues. My questions to the early adopters of ext4 are about whether the patches have performed as expected. What is your overall feeling about ext4? Do you think is solid enough for most users to trust it with their data? Did you find any significant performance improvements compared to ext3? Is there any incentive to move to ext4, other than sheer curiosity?"
