Re: ReiserFS vs XFS or JFS?

["MBR-2" <user=90@nabble.blu.org>]

 If the raw file containing your database is represented inside the 
structures used by a filesystem and something in the filesystem gets 
trashed, having a journaled database isn't going to help at all because 
the journaling information will be inaccessible, since it's also stored 
in the trashed filesystem. 

So, if you store your database inside a filesystem, double journaling is 
unavoidable if you want your data safe.  The preferable alternative is 
to avoid the structures involved in a filesystem, and allocate an entire 
partition to your database.  Then all you have to worry about is if the 
partition table were to get trashed, so make a backup of block 0 of the 
disk.
