If it was me, I would put the thinMetaLV directly on the fast device (because it is small) and I would cache the thinDataLV. Remember that some of what you are doing is pretty cutting edge. I wouldn't yet use caching + thin in production yet. Also, consider making your thin devices redundant (if they are not already via backend storage). brassow On Aug 9, 2014, at 11:26 AM, Oliver Rath wrote: > Hi list, > > what now worked: > > - creating a cached data-lv > - creating a non-cached meta-lv > - converting data-lv to a thinpool-device with meta-lv as metadata > > what not: doing the same thing with a cached meta-lv.
