Dear all I have a environment that disk online after switch root, link in /dev/disk/by-id is not generated when 69-dm-lvm.rules is executed, but i set link to filter in lvm.conf, so that pvscan failed to scan physical volumes and set environment variable LVM_VG_NAME_COMPLETE, finally, the logical volume is not activated. 69-dm-lvm.rules IMPORT{program}="(LVM_EXEC)/lvm pvscan --cache --listvg --checkcomplete --vgonline --autoactivation event --udevoutput --journal=output $env{DEVNAME}" ENV{LVM_VG_NAME_COMPLETE}=="?*", RUN+="(SYSTEMDRUN) --no-block --property DefaultDependencies=no --unit lvm-activate-$env{LVM_VG_NAME_COMPLETE} (LVM_EXEC)/lvm vgchange -aay --autoactivation event $env{LVM_VG_NAME_COMPLETE}" There are any ways to activate logical volume in this scenario? Looking forward to your reply, Thanks! _______________________________________________ linux-lvm mailing list linux-lvm@xxxxxxxxxx https://listman.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
