btrfsmaintenance

automate btrfs maintenance tasks on mountpoints or directories

Description

This is a set of scripts for the btrfs filesystem that automates the following maintenance tasks: scrub, balance, trim, and defragment.

Tasks are enabled, disabled, scheduled, and customised from a single text file. The default configuration assumes an installation profile where '/' is a btrfs filesystem.

The default values have been chosen as an even compromise between time to complete maintenance, improvement in filesystem performance, and minimisation of resources taken from other processes. Please note that I/O priority scheduling requires the use of BFQ or CFQ, and not noop, deadline, anticipatory, nor the new mq-deadline which uses blk-mq.
