I've got a RAID1 on two 1TB partitions, /dev/sda3 and /dev/sdb3 I'm adding two new disks, they will have bigger partitions /dev/sdc3 and /dev/sdd3 I'd like the BtrFs to migrate from the old partitions to the new ones as safely and quickly as possible and if it is reasonable to do so, keeping it online throughout the migration. Should I do the following: btrfs device add /dev/sdc3 /dev/sdd3 /mnt/btrfs0 btrfs device delete /dev/sda3 /dev/sdb3 /mnt/btrfs0 or should I do it this way: btrfs device add /dev/sdc3 /mnt/btrfs0 btrfs device delete /dev/sda3 /mnt/btrfs0 btrfs device add /dev/sdd3 /mnt/btrfs0 btrfs device delete /dev/sdb3 /mnt/btrfs0 or is there some other way to go about it? -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
