	Check my posts to this list... there is some nasty interaction
between soft RAID and ext3 since 2.5.X, already reported by several
people here, at linux-kernel and linux-raid.  Until now these reports
have gone unanswered, presumably because the people In The Know are
busy either trying to reproduce and diagnose it or because there are
even more critical -- or more interesting -- things to do.

	So for now the options are either not using software RAID, not
using 2.6, or not using ext3.  If you can afford it, I'd suggest
hardware RAID, and SCSI if you're really rich.
