Udi,

It's hard for me to tell from here, but it looks like your writes are really not 
going in at all, in which case there may be nothing (much) to salvage.

The EBS volume is mounted?  And fast (try listing a bigger dir or doing 
something that involves some non-trivial disk IO)?
No errors anywhere in the log on commit?
How exactly are you invoking the commit?  There is a wait option there...
