openSUSE: Fixes for various problems

Unresponsive system

High kernel CPU usage caused by btrfs-balance

Bug reports: 1063638, 1032027 and 1017461

May also be a fragmentation issue.


The system is intermittently unresponsive. When the system is unresponsive, there is often high disk usage and high kernel CPU usage. The system is unresponsive while btrfs-balance, btrfs-trim, or other automated filesystem maintenance is running.


The bug is not present when btrfs quotas are disabled. Snapper's limits must not have ranges when quotas are disabled.

sudo btrfs quota disable / sudo snapper set-config QGROUP= NUMBER_LIMIT=10 NUMBER_LIMIT_IMPORTANT=10
