I agree with your opinion that this is a serious issue and that it would be really great if someone would fix it, but I'm not sure if I would call it "critical", since people can and do use the current version of Tahoe-LAFS for backup. I guess the way they work-around this is some combination of (a) don't run a storage server on the computer which has the data that they want to back up, and (b) make sure that enough good storage servers are connected before doing a backup. Pretty kloogey! Note that there is a clump of tickets related to #699. I think my personal favorite way to improve this would be for someone to fix #573. I think it would solve your problem as well as several other people's problems. I also would like to see #778 fixed. #573 and #778 both seem like easier changes to make than #699. If someone like Kevan Carstensen wanted to get a little deeper into Tahoe-LAFS code without getting in *too* deep, I would recommend #573 or #778 but not #699. :-) Regards, Zooko tickets mentioned in this email: http://allmydata.org/trac/tahoe/ticket/699 # optionally rebalance during repair or upload http://allmydata.org/trac/tahoe/ticket/573 # Allow client to control which storage servers receive shares http://allmydata.org/trac/tahoe/ticket/778 # "shares of happiness" is the wrong measure; "servers of happiness" is better _______________________________________________ tahoe-dev mailing list [email protected] http://allmydata.org/cgi-bin/mailman/listinfo/tahoe-dev
