ea0463791d man: lvmlockd steps for changing lock type
were not quite correct

bbaaf4f1d3 lvmlockd: override unknown lock manager error numbers
When sanlock or dlm lock managers return an error number
that we don't recognize, replace it with a generic -ELMERR
which is defined in the set of special lvmlockd error
numbers.  Otherwise, an unknown lock manager error number
could be misinterpreted for something else if it happened
to overlap another set of error numbers (which they have
not thus far.)

e52d2e3bd8 lvmlockd: retry on other sanlock errors
These less common errors returned from sanlock should
also cause sanlock to retry the lock acquire:

- i/o timeout occurs during sanlock_acquire().
  other i/o on the same disk as the leases can cause
  sanlock i/o timeouts.

- low level disk paxos contention between hosts naturally
  causes one host to not acquire the lease.  There are a
  couple special error numbers associated with these cases
  that should just be recognized as a normal failure to
  acquire the lease.

838592a171 activate_lvs: use exclusive activation
There is no need to differentiation between clustered VG and normal VG.
As the activation depends on locking type.

Use unconditionally locally exclusive activation for pvmove.

9e2a68a981 activation: check subLV before skipping resume

c820b43fc0 activate_lvs: deactivate on uniterate

TODO: possibly remember which LVs where already activate and only those
take down - devices which are already in-use will stay active.

b5f62a143d metadata: Eliminate redundant nested VG metadata
Only lv_committed() now uses vg->vg_committed and it appears redundant
if its contents match the enclosing VG so don't waste cycles creating it
when that's known to be true when no write lock is held so the struct
won't get modified.

9958c41927 raid: reject message for 2-legged raid4/5 -> striped
Commit 763db8aab0 rejects 2-legged
conversions to striped/raid0 but different messages are displayed

763db8aab0 raid: reject conversion request to striped/raid0 on 2-legged raid4/5
raid4/5 LVs may only be converted to striped or raid0/raid0_meta
in case they have at least 3 legs. 2-legged raid4/5 are a result
of either converting a raid1 to raid4/5 (takeover) or converting
a raid4/5 with more than 2 legs to raid1 with 2 legs (reshape).

The raid4/5 personalities map those as raid1,
thus reject conversion to striped/raid0.
