I always start by asking what type of flash are you using - if you are using 
PCI-e flash devices or S-ATA/SAS flash, there is no real reason to use UBIFS or 
JFFS2 since the parts do wear levelling and so on internally.

For example, Google uses ext4 as their default file system for Android phones 
and tablets.

I don't know of anyone running gluster on raw flash backed file systems (i.e., 
embedded systems) but that might be fun to try :)
