[check online files and report if VG is complete] pvscan --cache --listlvs [--checkcomplete] <dev> . read only dev . create online file for dev . list VG using dev . list LVs using dev . [check online files and report if VG is complete] . [check online files and report if LVs are complete] [--vgonline] can be used with --checkcomplete, to enable use of a vg online file. This results in only the first pvscan command to see the complete VG to report 'VG complete', and others will report 'VG finished'. This allows the caller to easily run a single activation of the VG. [--udevoutput] can be used with --cache --listvg --checkcomplete, to enable an output mode that prints LVM_VG_NAME_COMPLETE='vgname' that a udev rule can import, and prevents other output from the command (other output causes udev to ignore the command.) The list of complete LVs is meant to be passed to lvchange -aay, or the complete VG used with vgchange -aay. When --checkcomplete is used, lvm assumes that that the output will be used to trigger event-based autoactivation, so the pvscan does nothing if event_activation=0 and --checkcomplete is used. Example of listlvs ------------------ $ lvs -a vg -olvname,devices LV Devices lv_a /dev/loop0(0) lv_ab /dev/loop0(1),/dev/loop1(1) lv_abc /dev/loop0(3),/dev/loop1(3),/dev/loop2(1) lv_b /dev/loop1(0) lv_c /dev/loop2(0) $ pvscan --cache --listlvs --checkcomplete /dev/loop0 pvscan[35680] PV /dev/loop0 online, VG vg incomplete (need 2).
