Thanks, Anand
Not sure I understand fully what you are asking, but I deleted a swap partition on the drive a while back and increased the size of the btrfs partition (with gparted). I have rebooted many times since then. That is all the changes I have done to this SSD recently.
Thanks.
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 scrub started at Sat May 2 08:03:46 2015 and finished after 241 seconds total bytes scrubbed: 109.06GiB with 0 errors scrub device (id 0) canceled scrub started at Sat May 2 08:03:46 2015 and was aborted after 0 seconds total bytes scrubbed: 0.00B with 0 errors 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.--
