Now that Fedora 32 has fstrim.timer enabled by default... how about discards for the things that fstrim doesn't get? Two main things I know of: - swap: Do discard at swapon time by setting "discard=once" in /etc/fstab would be somewhat similar to the periodic fstrim call. I don't know how much impact the "discard=pages" option might have (the man page says it is asynchronous, but it might make low-memory situations worse). - logical volumes: Set "issue_discards = 1" in /etc/lvm/lvm.conf so that removed LVs get discarded. -- Chris Adams <linux@xxxxxxxxxxx> _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx
