Ok, I found a solution: I deactivate the VG kvm_disk0 with vgchange -an kvm_disk0, after that I set the filter: filter = [ "r|/dev/mapper/data-kvm_disk0|", "r|/dev/kvm_disk0|"] without "a|.*|" !!!! and do a update-initramfs -u -k all Perfect :-) It seems that the allow filter overrules the remove option. Is my filter correct?? ps: lvm version: 2.02.54-1ubuntu4.1ppa5 Regards, Erik ----- Original Message ----- From: "Bryn M.

There is no need to reboot. If pvs/vgchange/vgdisplay etc. still display the nested VG and its PV your filters are wrong or insufficient. Examine the -vvv output from the tools to see the filter decisions that are being made. Since you haven't mentioned any of the versions you are using you may also want to remove the LVM2 cache after editing the filter (current versions clear it automatically but older releases would still show filtered devices if they exist in the cache. > and do a update-initramfs -u -k all You need to know whether this is the correct command for your distribution and that it's affecting whatever kernel/initramfs combination the machine boots by default (and also that it actually works and creates a new initramfs). But for now I would ignore boot problems and focus on the filter. Don't try to solve all the problems at once as that just makes it more confusing. When you have confirmed that your filter settings correctly exclude the nested VG you can move on to making sure those settings are applied at boot.
