LVM passes discards through automatically, assuming the block device under the PV supports them. The issue_discards option tells LVM to issue discards itself when PV space is released (e.g. an LV is removed/reduced). I'm not sure why issue_discards=1 is not the default, but that's a separate issue from this change. -- Chris Adams <[email protected]> _______________________________________________ devel mailing list -- [email protected] To unsubscribe send an email to [email protected]
