d46c2f1c94 cache: improve creation code
Move code to better locations.
Improve test and remove invalid ones
(i.e. no reason to require cache size to be >= then origin).

Correctly comment where the code is doing actual conversion
of other existing volume - we do already a similar thing with
external origins.

Lots of new command line options and combinations is now supported.
Hopefully older syntax still works as well.

lvcreate --cache --cachepool vg/pool  -l1
lvcreate --type cache --cachepool vg/pool  -l1
lvcreate --type cache-pool vg/pool  -l1
lvcreate --type cache-pool --name pool vg  -l1
... and many many more ...

cb273fe164 pools: move removal of _pmspare
Since _pmspare is internal volume move it to
lv_remove_single -  so it's automatically removed with
last remove thin-pool.

a8497e329b lvconvert: options splitcache, split, uncache
--splitcache
  Splits only cached LV (also pool could be specified).
  Detaches cachepool from cached LV.

  --split
  Should be univerzal command to split various complex targets.
  At this moment it knows cache.

  --uncache
  Opposite command to --cache. Detaches and DELETES cachepool for
  cached LV.

Note: we support thin pool cached metadata device for uncaching.
Also use may specify wither cached LV or association cachepool device
to request split of cache.

487723e0df lvcreate: refactor code
Over the time lvcreate code has accumulated various hacks.
So try to move that code in right places.

Detect all types early in _lvcreate_params() so functions like
_read_size_params() do not need to change volume types.

Also ultimately respect give volume --type, that its shortcut
(-T, H, -m, -s) and after that options which do type estimation.
(i.e. --cachepool, --thinpool)

Avoid repeative tests - if we know all types are decode at once
place we can 'optimize' number of validations.

91615603cd toollib: Rewrite process_each_lv.
Copy the same form as the new process_each_vg.

The failed_lvnames arg is no longer used since the
cmd_vg replicator wrapper was removed.

91198ac13e man: lvmcache better cache mode info and other command variations 2014-10-02 12:01:58 -05:00
David Teigland
17ab39f743 cache: include cache mode in vg metadata and display
The cache mode of a new cache pool is always explicitly
included in the vg metadata.  If a cache mode is not
specified on the command line, the cache mode is taken
from lvm.conf allocation/cache_pool_cachemode, which
defaults to "writethrough".

The cache mode can be displayed with lvs -o+cachemode.

a976226e81 cleanup: remove compiler warning about possible uninitialized variable use

5011cac9cf filters: add cmd->full_filter - composite of cmd->filter and cmd->lvmetad_filter
There are actually three filter chains if lvmetad is used:
  - cmd->lvmetad_filter used when when scanning devices for lvmetad
  - cmd->filter used when processing lvmetad responses
  - cmd->full_fiilter (which is just cmd->lvmetad_filter + cmd->filter chained together) used
    for remaining situations

This patch adds the third one - "cmd->full_filter" - currently this is
used if device processing does not fall into any of the groups before,
for example, devices which does not have the PV label yet and we're just
creating a new one or we're processing the devices where the list of the
devices (PVs) is not returned by lvmetad initially.

Currently, the cmd->full_filter is used exactly in these functions:
  - lvmcache_label_scan
  - _pvcreate_check
  - pvcreate_vol
  - lvmdiskscan
  - pvscan
  - _process_each_label

If lvmetad is used, then simply cmd->full_filter == cmd->filter because
cmd->lvmetad_filter is NULL in this case.
