Only one good thing is that this is "backup machine" so I can tranfer all data from "main machine". But it is 3TB so it would take about 40days to fully transfer all data :-( Is there any possible way to (partially) restore some data? (I use rsync syncing data between both machines) -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
