Re: [linux-lvm] Another strange setup by a newbie, but strange oops resulted while trying vgextend/vgmerge!



A short parable seems to be in order here.


  There once was a large penguin rookery located on an island that was
  designated as K-2.2.18.  The penguin population that lived there was large
  and plentiful due to the fact that it provided suitable protection and
  sustenance.  Due to this the population had grown large and was starting
  to look for new territory to occupy.  Lo and behold they discovered
  a substantially larger island known as K-2.4.0 which had a wealth of
  untapped resources that would allow the colony to expand in the future.
  Unfortunately, the distance between K-2.2.18 and K-2.4.0 was large and
  full of many unknown dangers (not the least of which were large killer
  whales looking for tasty penguins to snack on).  

  Despite this, many of the penguin population decided that the risk and
  effort necessary to reach K-2.4.0 was acceptable because of the
  opportunities it provided.  This divided the penguins into a number of
  groups:

  o Group #1 was composed of some of the elder penguins, who had made
  successful ocean crossings in the past.  They traveled together in a flock 
so
  as to mitigate their danger.  They arrived successfully with only minor
  injuries.

  o Group #2 was formed from mature and adolescent penguins.  When they
  ventured forth they either swam in groups for protection or as individuals
  who counted on their own strengths (speed and cunning) to insure a
  successful journey.  Despite this they still encountered dangerous schools
  of jellyfish that inflicted damage upon some of them.  These penguins
  required some time to recuperate after completing their journey

  Group #3 was made up of fledging penguins, who having seen others make the 
  journey, decided they could do so as well.  They launched from shore with
  a plan that consisted of nothing more than a dream of Island K-2.4.0 for
  they were unexperienced in such endeavors.  Many of them became lost
  during the journey or were eaten by killer whales hunting for the
  inexperienced.  Of the remaining penguins, the majority turned back to
  K-2.2.18.  A few of the original group did make it K-2.4.0 and spent much
  time recuperating from the exhausting swim and the mental trauma from having
  seen their friends eaten.

  Group #4 was all the other penguins left on K-2.2.18.  These penguins waited
  a number of months till the ocean calmed down and the killer whales migrated
  to warmer waters.  A this point the majority of them departed from K-2.2.18
  for K-2.4.0 with friendly schools of dolphins to guide them (designated
  Pod-RedHat, Pod-SuSe, Pod-Sistina, etc...).  They arrived without incident
  on K-2.4.0.  Those left on K-2.2.18 maintained the rookery and lived happy
  ever after.

The moral of the story -- If you are a Group #3 penguin don't expect
                          much sympathy from your wiser or more cautious
                          brethren when you get eaten.
