Hi,
before my ssd crashed, my /home partion was sitting on md raid1 consisting =
of=20
partition on disk and iScsi LUN in network, it was created with bitmaps and=
=20
iscsi lun was set writemostly.
So when i came to work, i fired up iscsi, added lun to raid and partial res=
ync=20
went ahead.
Before leaving work, i failed iscsci disk and kicked it from raid.
I would like to use something like this with btrfs, without mdraid below it.

Is it somehow posible?
1) I can't go below 2 devices.
2) Does btrfs support resync only of changed blocks like mdraid with bitmap=
s?

Thanks
Libor
