Hi,
My laptop has a small ext4 /boot partition /dev/sda1 and a large btrfs
partition containing / and /home as a sub volume /dev/sda3
When I run scrub on /dev/sda3 and check status with sudo btrfs scrub
status -d /dev/sda3 I get:
scrub status for 3d52dc93-c89f-453f-965d-8601d11e7710

we are reading an uninitialized device struct and that uninitialized
devid happens to be 0. looks like num_devices count went haywire.
in this config was there any device delete ? or a reduce in # of
devices? and has the system been rebooted after that ?
Thanks, Anand
As device (id 0) is indicated, but I have no idea what it is.
When I run scrub with a script (cron) the same device (id 0) shows up in
a warning:
/etc/cron.daily/btrfs-scrub:
WARNING: device 0 not present
scrub device /dev/sda3 (id 1) done

What is this device (id 0) which never gets scrubbed but always shows up?
I'm running Ubuntu 15.04 with the 3.19.0-16-generic kernel.
P.S. I am not a developer.
