<snip from stefan> I give that a try ... as I set up a fresh new btrfs-subvolume to do a fresh new build based on my <at> world only yesterday I will see if I can do it with gcc 4.9 while I am at it.
Let's see if things work out and if it gets any better. <end/snip> Hello Stefan, Well. OK. I'm working on a fresh install of gentoo with btrfs. Subvolumes have me a bit mystified still. I mostly followed this doc for a basic (raid 1) configuration with btrfs: http://wiki.gentoo.org/wiki/Btrfs_native_system_root If you would be so cool as to post your subvolume setup; I'd be very grateful: My disks look like this: (livecd)# fdisk -l Disk /dev/sda: 1.8 TiB, 2000398934016 bytes, 3907029168 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disklabel type: gpt Disk identifier: A278FD71-0AFC-448C-817F-BAA52F97F6E1 Device Start End Size Type /dev/sda1 2048 8191 3M BIOS boot partition /dev/sda2 8192 1024000 496M Linux filesystem /dev/sda3 1026048 3907029134 1.8T Linux filesystem Disk /dev/sdb: 1.8 TiB, 2000398934016 bytes, 3907029168 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: gpt Disk identifier: 08A52E74-1A4D-4681-9BF6-0F3A436251E0 Device Start End Size Type /dev/sdb1 2048 8191 3M BIOS boot partition /dev/sdb2 8192 1024000 496M Linux filesystem /dev/sdb3 1026048 3907029134 1.8T Linux filesystem (livecd) # gdisk /dev/sda GPT fdisk (gdisk) version 0.8.10 Partition table scan: MBR: protective BSD: not present APM: not present GPT: present Found valid GPT with protective MBR; using GPT.

I'm just "dense" I guess because the aforementioned doc, I think derived from some of "Duncan's" postings just does not click for me. I've botched a few runs at btrfs (raid1) one on fresh gentoo installs, just so you know.... Your guidance is keenly appreciated. James
