Don't forget to have a maintenance program - run a scrub regularly once a week or so - I have enough btrfs drives (22 qemu files, 4 WD Greens att) to see about one or two scrub fixable errors a week with no obvious cause, sometimes serious (in a critical file). My experience is that if you ignore these errors they seem to increase over time resulting in a crash and burn. Keep an eye on your logs as btrfs will list the errors there as well ("grep -i btrfs /var/log/messages"). For the ones scrub cant fix, delete the file and restore from backup. Errors that require off-line fixing (btrfsck) are the ones where I have lost file systems - though I have not seen this in the last 6 months. I am quite practised in restoring from backups because of btrfs :) BillK
