Subject: Is SATA ALPM safe with btrfs now (no more corruption)?
Date: Thu, 28 May 2020 21:26:15 -0700 [thread overview]
Message-ID: <20200529042615.GA32752@merlins.org> (raw)
TLP allows SATA power management: SATA_LINKPWR_ON_BAT=max_performance
There are some old posts that talk about corruption if you enable this
with btrfs:
https://wiki.archlinux.org/index.php/TLP#Btrfs
says not to enable it
https://forum.manjaro.org/t/btrfs-corruption-with-tlp/25158
https://github.com/linrunner/TLP/issues/128
says it may not be safe
https://www.reddit.com/r/archlinux/comments/5tm5uh/btrfs_and_tlp/
also talks about corruption
https://www.reddit.com/r/archlinux/comments/4f5xvh/saving_power_is_the_btrfs_dataloss_warning_still/
say it's probably ok
My feeling is that it's probably ok nowadays with a 5.6+ kernel.
Would anyone disagree?
Thanks,
Marc
