BTRFS in laptop-mode

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Welcome,

What are perspectives on BTRFS complying with laptop-mode and stop writing to disk every 30 sec?

The thread was asked several years before (http://mailman.samwel.tk/pipermail/laptop-mode/2012-February/000520.html), but time went by and maybe the situation became a little more on the bright side...? With kernel 3.8.11 I can still see with lm-profiler a lot of "btrfs-transacti" and ""btrfs-submit-1" events, roughly once every 30 sec.

Is there any tunable switch, that can delay such writes to, say, 15 minutes, or better yet: until the disk started spinning anyway?
