I've been having good luck with my /boot on a separate 1GB RAID1 btrfs filesystem using grub2 (2 disks only! I wouldn't try it with 3). I should note, however, that I'm NOT using compression on this volume because if I remember correctly it may not play well with grub (maybe that was just lzo thou

Packed small files

Are there any caveats or gotchas around using btrfs to store millions of small (size<64bytes) files? -- To unsubscribe from this list: send the line
