broken patch
here is an untested and partially written patch for this issue. If it is helpful to you, great.
pushed to git https://git.fedorahosted.org/cgit/lvm2.git/commit/?id=17ab39f7431fdad4c8a445bd1e78a288eeb64bc1 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.
