Some users suggest that XFS is not affected by this, but this has not been entirely confirmed. See kernel bug 6242 for updates on this bug. Note: There are also reports that Journaled Filesystems are problematic on all Software-RAID levels. No kernel bugs have been submitted regarding this bug as of yet. A number of the reports involve using cryptoloops which are known to cause corruption. See http://forums.gentoo.org/viewtopic-t-412467.html for more information. This thread should be taken with a grain of salt." Can someone shed some light on this? I have XFS on my raid and *had* problems when unpacking large archives with many small files.
