#!/usr/bin/env python3

# The goal of this is to gradually balance a btrfs filesystem which contains DM-SMR drives.
# Such drive are described in detail at https://www.usenix.org/node/188434

# A normal drive should be able to balance a single 1GB chunk in under 30s.
# Such a stripe would normally be written directly to the shingled blocks, but in the case
# it was cached, it would take roughly 100s to clean.

# So our heuristic here is:

#!/bin/sh

# prefer cfq (el7), then bfq (el8), then do nothing

if grep -q cfq /sys/block/sd*/queue/scheduler; then
  # tune SSDs to use cfq scheduler and spinning disks to use cfq also
  for DISK in /sys/block/sd*; do grep -q 0 ${DISK}/queue/rotational && echo cfq > ${DISK}/queue/scheduler; done
  for DISK in /sys/block/sd*; do grep -q 1 ${DISK}/queue/rotational && echo cfq > ${DISK}/queue/scheduler; done

  # tune cfq not to penalize writes when reading heavily
