Description Rolf Fokkens 2013-10-15 17:39:09 UTC
Please add bcache support to python-blivet, so users can build storage configurations the include 'bcached block' devices.

rebasing (missed f20 target)

Comment 2 Rolf Fokkens 2014-01-28 15:00:48 UTC
dm-cache was not ready for F20:

http://www.redhat.com/archives/dm-devel/2013-August/msg00138.html

But dm-cache is now progressing well:

http://www.redhat.com/archives/dm-devel/2014-January/msg00063.html

So if dm-cache is also ready for F21, we should consider:
- Are both bcache and dm-cache to be supported in Anaconda/python-blivet?
- If not, which one is the best choice?

Comment 3 Rolf Fokkens 2015-01-04 14:15:41 UTC
Given the fact that serious changes on bcache are planned, I think this change should be postponed until further notice:

Comment 7 Vojtech Trefny 2023-04-27 09:32:33 UTC
We unfortunately won't have capacity to add this feature. Blivet supports cached LVM logical volumes (both with dm-cache and dm-writecache) so that can be used as an alternative. We might consider adding support for bcachefs in the future when it's available in the upstream kernel.
