I had to install at least 2.6.37 to have a kernel with an advanced enough balance feature to actually reclaim the free space and report it correctly too. Still, I had so much kernel crashes during this balance operation that even after numerous retries I still hadn't once completed it (on a FS of merely 300GB). Fortunately Zheng Yan coded a patch, which I applied to 2.6.38-rc2, so that I could finally run - and finish - the balance operation. Additionally this version of btrfs is more clever in not wasting the free space to begin with, hence making future rebalances for reclaiming free space no longer necessary. That patch is released on this list on january 26th, called "Fix balance panic". If you experience the same, you could try applying this patch too. There is no (pre-built) kernel yet with this patch already applied. - Erik. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
