Kind of late response, but I strongly agree with Thomas. I've had my share of truncated files after unclean shutdowns (every single time), some kernel modules being among the victims. If you decide to decide to use ext4, then it's almost mandatory to use the 'nodelalloc' mount option, unless you're positive that unclean shutdowns are unlikely in your setup or you don't care about lost data. -- X.
