Description Marian Csontos 2014-05-20 15:19:41 UTC

Commit 37502d2733c8ba8bc0d93e6f126534f23111fc3e added support of cache LVs by including dm-cache modules unconditionally.

Additional code is required to make this work with 'hostonly' for cache devices and for all underlying block devices.

This should be mostly identical to thin-pool handling.

Comment 1 Marian Csontos 2014-07-02 12:12:43 UTC

I must have misunderstood how dracut modules work - seems the support is conditional after all.

Now we only need to remind anyone trying to use cache for root FS (among other things) to not forget to call `dracut -f` or will need a LiveCD...
