The first is some second-hand quote of Ted T'so who just *happens* to have a bone to pick with other filesystems. All the gentoo article states is some info from the XFS docs about XFS' "aggressive" caching and potential *data* loss (not FS corruption). While it's not well-known that XFS sucks in a power outage, it is well-known that it writes journal before data. This is a design choice that helps ensure that while you may lose data in a power outage, you won't lose your filesystem. I know no one here seriously thinks that they won't lose data in a power outage no matter what FS they use so I'm still unsure how that makes XFS suck. Bottom line is after 5 years of almost nothing but XFS on many, many computers (most of them not on UPS), I've had nothing but good fortune with XFS. OTOH, I've got a corrupted EXT3 system sitting here I'm trying to repair for a customer after someone turned it off, and my one attempt with JFS (when I got my first 64-bit PC) led to almost immediate disaster. Bottom line is that if you lose power you risk losing data. My experience has been that not only does XFS not fair worse than the other filesystems, it appears to fair better.
