He addressed it theoretically, and only in relation to reiserfs, not ext3. But in fact I disagree with one assertion that Daniel makes: "but writing metadata more frequently does encourage data to be written more frequently as well" In it's default configuration, XFS avoids writing data out to disk until it absolutely has to, or a *significant* amount of time has elapsed. Only by tweaking /proc settings have I gotten it to flush out data in a reasonable amount of time. Are you seriously telling me that in all the years you have run XFS filesystems, you have never seen /var/log/messages get padded with nuls? That is the kind of "corruption" that XFS is well known for. (BTW, I _know_ this is a security feature. But the fact is that ext3 users pretty much _never_ see this kind of data, um, "security"). It may be great at maintaining it's own consistency, but it seems particularly predatory to the files contained within it. I've already mentioned a recent corruption I had with XFS on one of my systems... Besides, every time this discussion has come up here, the majority of particpants have agreed that ext3 is the least likely to corrupt data. Don't get me wrong. I like XFS, and I am running it on my laptop and desktop systems. However I have tweaked the settings so that it behaves like I want, and am very cautious about just hitting the reset/power button when I get a lockup. I have learned that the hard way. And my "bottom line" is: if someone came here and asked "what is the most reliable filesystem", my answer would be ext3. Hands down. -Richard -- gentoo-user@gentoo.org mailing list
