Plattencrash bei LVM

-P | --partial
              When set, the tools will do their best to provide access to vol‐
              ume groups that are only partially available (one or more physi‐
              cal volumes belonging to the volume group are missing  from  the
              system).   Where part of a logical volume is missing, /dev/ioer‐
              ror will be substituted, and you could use dmsetup  (8)  to  set
              this  up  to  return I/O errors when accessed, or create it as a
              large block device of nulls.  Metadata may not be  changed  with
              this option. To insert a replacement physical volume of the same
              or large size use pvcreate -u to set the uuid to match the orig‐
              inal followed by vgcfgrestore (8).

--removemissing
              Removes all missing physical volumes from the volume group, if there are no log‐
              ical  volumes  allocated  on  those. This resumes normal operation of the volume
              group (new logical volumes may again be created, changed and so on).


              If this is not possible (there are logical volumes referencing the missing phys‐
              ical volumes) and you cannot or do not want to remove them manually, you can run
              this option with --force to have vgreduce remove any partial LVs.


              Any logical volumes and dependent snapshots that  were  partly  on  the  missing
              disks  get  removed completely. This includes those parts that lie on disks that
              are still present.


              If your logical volumes spanned several disks including the ones that are  lost,
              you  might  want to try to salvage data first by activating your logical volumes
              with --partial as described in lvm (8).
