[clue] btrfs vs ZFS question

[Dennis J Perkins]

Sean, does ZFS let you do these things?

Btrfs lets you do the following without stopping anything:

1. Add or remove partitions.  If you remove a partition, make sure the
remaining drives have enough capacity.
2. Resize a btrfs system.
3. Balance the data.
4. Switch between single disk, RAID 0, RAID 1, or RAID 10 configs.

Shuffling data around as a result of any of these operatins is done in
the background and might take hours.
