[Moosefs-users] Chunks replication : preference to "rebalance" instead of goaling

[Florent B. <fl...@co...>]

Hi all,

It seems that on my MooseFS installation, the master server prefers to 
rebalance over CS chunks with goal satisfied, instead of taking care of 
chunks in undergoal situation.

I added a CS recently, and after a master restart, some chunks have 
only 1 valid copy (goal 2 or 3), and it stays like that for a few 
minutes (undergoal chunks are decreasing very slowly). During this time, 
some chunks where rebalanced over CS (I see that because some chunks are 
getting overgoal, then deleted, etc...).

Is it possible to set a more important priority on chunks that are 
undergoal ? And only then rebalancing the others. It's very dangerous 
because some files could have only one valid copy during hours...

I'm on 1.6.24, with 4 CS and 1 ML. Debian Squeeze for all, except the 
last added CS on FreeBSD.

My config is the default one except:

CHUNKS_WRITE_REP_LIMIT = 3
CHUNKS_READ_REP_LIMIT = 10

Thank you for help :)
