Re: [Moosefs-users] chunks valid copies problem

[jyc <mai...@gm...>]

Hi, thanks for your answer

how can i help you with this problem ?
i can tell that i still have these 5 chunks with one valid copie, and a 
goal of zero.

i just don't know if it's possible, but it would be cool to make request 
to the mfsmaster process, like sql request :

select chunks where file_goal=0 and valid_copies=1; :-)

for exemple.

there must be a way to find it using bash and mfsfileinfo ,but i think 
maybe i would be a killer app for debugging

thanks again for you great job
