Hi folks,
Just wondering if any of you have experience with btrfs file system and SSDs.
What do you recommend by way of fstab settings/other measures, e.g. trim.
I strongly suggest you to accept the defaults on this regard.
Btrfs does check /sys/block/sdX/queue/rotational for hdd / sdd and sets its "ssd" option to default=on if the above gives back "0" (Zero), see: https://btrfs.wiki.kernel.org/index.php/Mount_options For discard / trim, well there are different opinions. For me, using "/usr/sbin/fstrim [options] /mount/point" via cron is the prefered solution, YMMV. Regarding noatime / relatime(default), the discusions where "spirited", but like with trim, there is no universal right or wrong. Keep one thing in mind: Btrfs is not the end all, best for all uses filesystem. Thinking for yourself beforehand is encouraged. - Yamaban.
