--removemissing flag.

reveals:

vgchange -ay --partial

[gentoo-user] recover from disk crash lvm2 group

Hello,

One of the disks in a 3-disk lvm2 group crashed.  I would like to
continue with the remaining 2 disks.  How to remove the non-functioning
disk from the group and re-create the volume with 2 disks?  I have backups.

# vgremove home_vol

  Couldn't find all physical volumes for volume group home_vol.
