--- Begin Message ---Package: pm-utils Version: 1.4.1-6 Severity: normal I currently have pm-utils on hold at version 1.3.0-3. Looking ahead in the changelog, I saw: Current hooks when switching to battery: [...] - [harddrive] More aggressive harddrive spindown times [...] - [journal-commit, xfs_buffer] Delay ext[34]/ext journal/metadata writeback - [laptop-mode] Delay hard disk writeback times of dirty caches, to avoid spin ups In general, this seems like a bad idea to do automatically without the user's knowledge; it makes the system far less robust against sudden failures. I haven't worried about losing data due to a system crash (usually self-inflicted due to kernel hacking) in a long time. I don't want to have to start now. But in any case, none of these hooks need to run on a non-rotational device such as an SSD. SSDs can idle very effectively the moment they have no work to do, without a long spin-up/spin-down transition. So, you don't need to make the system less safe to minimize writebacks on such systems. You can detect non-rotational devices by looking at /sys/block/$device/queue/rotational , which will contain a 1 (rotational) or 0 (non-rotational such as an SSD). For instance, on my system: ~$ cat /sys/block/sda/queue/rotational 0 (Note that these files only exist for the top-level devices like sda, not partition devices like sda1.) So, if you see rotational -eq 0 on a device, you shouldn't run the harddrive, journal-commit, xfs_buffer, or laptop-mode hooks for the filesystems on that device. (I'd argue more generally against running those hooks on *any* device, but this seems like the right place to start, and it solves my immediate problem. :) ) Thanks, Josh Triplett
