Parent article: Improving ext4: bigalloc, inline data, and metadata checksums

My system was using Linux Software RAID, so there wasn't a cheap RAID controller in the mix. You could be correct about the hard drives doing caching, but it seems odd that I've never seen this with ext3 but did with ext4. I am still hoping it was simply bad luck, bad timing, and writeback caching... but I'm also still pretty nervous.

Ah... reading http://serverfault.com/questions/279571/lvm-dangers-and-caveats makes me think I was a victim of LVM and no write barriers. I've followed the suggestions in that article. So maybe I'll give ext4 another try.
