There have been many reports of extensive ext4 filesystem corruption
during the current 2.6.32-rc kernel series (see for example
http://bugzilla.kernel.org/show_bug.cgi?id=14354), after unclean
I personally experienced this twice on a desktop and lost hundreds of
files (looked like roughly the last half-hour of activity) each time.
In my case this didn't touch anything too critical (although I had
mild corruption of an openafs git clone), but having this happen on a
/vicepx partition would not be pleasant. It definitely needs to
mature before being considered for use as a server data store.
