how btrfs uses devid?

Dear all: If a btrfs device is missing, the command tool tells user the devid of the missing devices. I understand that each device (disk) in a btrfs volume has been assigned a uuid (UUID_SUB field in udevadm info output). If the device is missing, it's hard to tell user to input such uuid

Btrfs send / receive freeze system?

Hi everyone. It's a few weeks that I converted my root partition into btrfs with three sub- volumes named boot,root,home. I'm booting with /boot on subvol. I'm using btrfs send and receive to make backup of the three snapshotted subvolumes on a second btrfs formatted drive with three commands

Btrfs send / receive freeze system - Addendum

Sorry, I forgot to mention that this freeze is happening after I converted this backup drive to btrfs, before it was XFS. So sending to XFS drive didn't caused the freeze while sending with the same script to btrfs formatted drive freeze the system. Kernel and btrfs progs were the same.
