the background polldaemon is allowed to start. It can be used standalone or in conjunction with --refresh or --available y. Control over when the background polldaemon starts will be particularly important for snapshot-merge of a root filesystem. Dracut will be updated to activate all LVs with: --poll n The lvm2-monitor initscript will start polling with: --poll y NOTE: Because we currently have no way of knowing if a background polldaemon is active for a given LV the following limitations exist and have been deemed acceptable: 1) it is not possible to stop an active polldaemon; so the lvm2-monitor initscript doesn't stop running polldaemon(s) 2) redundant polldaemon instances will be started for all specified LVs if vgchange or lvchange are repeatedly used with '--poll y' Signed-off-by: Mike Snitzer <snitzer@redhat.com>
