Hello everybody,
I have a Raid-1 btrfs filesystem with 5 devices and I was running
btrfs scrub once a week. Unfortunately, one disk (4TB) failed.
I added two new (6TB each) disks in the array and now I get:

Hello,
I have kubuntu 14.10 with 3.17.1 kernel and 3.17 tools
the setup of data pool was btrfs raid1, 3x6TB + 1x3TB. Time has come
to replace old 3TB with new 3TB.
As usual I added new device and deleted the old one, system started
relocating chunks and I went to bed...

This isn't a btrfs-send or a btrfs-receive question:

How were you planning on providing credentials to sudo?
