Just a weird question here. Since swap should ordinarily be encrypted if you encrypt any part of your data at all, I have opted at this point to either put it inside a volume that might end up getting cached, or to disable that cache and put the swap in its place. What I am saying is that in my current scheme there is going to be a small cache drive and one part of the cache drive is going to serve unencrypted data and the other part is going to serve encrypted data. Supposing that, the swap would be in the encrypted part. But using cache (lvmcache) on swap is completely ludicrous right?
Hi Yes, it would be seriously bad idea to use 'swap' on cached LV... There are already unsolved issues with plain devices and swapping :) and you want to put caching logic into this stack.
Alternatively you could put the swap on the SSD (in this case) and not have any cache for the other part of the drive. What do you think? It makes no sense and it makes no difference, right.
