Hi,
before my ssd crashed, my /home partion was sitting on md raid1 consisting of
partition on disk and iScsi LUN in network, it was created with bitmaps and
iscsi lun was set writemostly.
So when i came to work, i fired up iscsi, added lun to raid and partial resync
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 bitmaps?
Thanks
Libor
