/etc/systemd/system/btrfs-balance.d/schedule.conf the interval to something else (eg you comment out OnCalendar=weekly) it enigmatically restores this setting on reboot .. btrfs maintenance is simply production killer .. needs to be removed .. in 10/10 times here it causes on server with mechanical disk to switchover HAed application from active to standby node regards, daniel -- You are receiving
