ext4 over xfsext4 over xfsPosted Jan 23, 2009 3:07 UTC (Fri) by rfunk (subscriber, #4054)In reply to: Ext4 to be standard for Fedora 11, Btrfs also included (heise online) by giggls Parent article: Ext4 to be standard for Fedora 11, Btrfs also included (heise online)
If ext3 is anywhere near as reliable as ext3, then ext4's big advantage
over xfs is much lower risk of losing your entire filesystem when something goes wrong.

I believe you're referring to mounting ordered mode by default. It's the main reason I use EXT3 nearly everywhere. EXT4 has it, and it's the default just like EXT3.
Found this nugget and others in 2.6.28's "ext4.txt" documentation.
Nope - there are other problems with xfs Posted Jan 23, 2009 10:03 UTC (Fri) by khim (subscriber, #9252) [Link] Actually it all is related to any stress-conditions. Fill the XFS partition with bittorrent-downloaded files (no pre-allocate!) and the only way to save this partition is to backup everything and restore from backup. Yes, it's nasty thing to do with the FS (bittorrent with pre-allocate more- or-less equals to creation of files from pieces in random order and if you fill the FS to 100% there are no way to radically optimize layout - because all files must be sparse or else they'll not fit), but I still expect that any sane filesystem will be slow after that, not dead. XFS failed this test consistently for a few years in row and eventually I've just stopped caring and stopped using it...

Well, I was specifically thinking of the other side, how badly xfs has
screwed up filesystems of mine in the past. And I started out as a fan of xfs, having used it on SGIs. But between losing an entire filesystem on an external drive, and getting strings of zero-bytes strewn without warning throughout files on another filesystem, I'm done with xfs.
