rebalance speedup

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I see. Another related question. Now if I start a fix-layout rebalance, 
I don't can't see any status update using "gluster volume rebalance 
<vol> status. Is it by design or do I need to use a different command?

Thanks,
