Package: btrfs-tools
Version: 3.17-1.1
Severity: normal
File: /sbin/btrfs
Dear Maintainer,
Running 'btrfs check' on a 1TB filesystem brought my system to its knees. top
shows:
17892 root 20 0 4860028 4.237g 528 D 31.2 54.5 9:29.66 btrfs
I'm not sure if this could be due to something peculiar about this
filesystem. I don't think there's anything odd about it, but here's some
output:
# btrfs filesystem show /dev/sdc1

The lowmem mode is there for such machines; it is pretty mature by now.
It got added in 2016 -- your report is from 2015.
Meow!
