Re: [Gluster-devel] glusterfs file replication question

[devzero]

oh, that`s a real bandwidth killer / i/o hog then :)
think of 500gig disk with lot`s of large files , connected with 100mbit 
network. 
if many of the files are open at the time of a node going down, that will take 
hours then for resync.

is it planned to adress this to be handled more fficiently? for example just 
like fr1 from enbd ? (http://www.it.uc3m.es/ptb/nbd/#Intelligent_mirroring )

roland
