I read the document you pointed to, but I do not see anything there that
says what I need to do in OpenRC.

Can you please elaborate?

Thanks,

William

After looking at this a bit further, I believe this new init script
should be part of lvm2 and not directly in OpenRC.

Comment 3 Andreis Vinogradovs ( slepnoga ) 2013-07-10 16:36:41 UTC

This is dm-cache setup script from upstream
https://github.com/mingzhao/dm-cache/blob/master/dmc-setup.pl

robbat2, your opinions ?

You should use it via LVM, or use bcache instead
