There was NEVER a stable package release of sys-fs/clvm.

Correspondingly, you must use the ~arch releases of sys-fs/lvm2 for good
CLVM support.

Additionally, the clvm use flag is use.mask'd for nearly all
architectures, because nobody has tested it.
x86 is the only arch that has it unmasked:
/usr/portage/profiles/arch/x86/use.mask:-clvm

Could you elaborate on how it doesn't work? What is your SAN hardware?

Upstream LVM2 merged device-mapper into LVM2, that's why the dep has a
|| block.
