= Proposed Self Contained Change: Anaconda Using LVM DBus API = https://fedoraproject.org/wiki/Changes/Anaconda_Using_LVM_DBus_API Change owner(s): * Vratislav Podzimek <vpodzime AT redhat DOT com> * Jonathan Brassow <jbrassow AT redhat DOT com > A new DBus API for LVM is being created so let's make the installation process use it for setting up LVM storage. == Detailed Description == For quite a long time there has been a request for a better API for LVM than what the current CLI tools provide. After a quite long discussion between the interested groups it has been decided that a DBus API should be the best choice. The LVM team has thus been working on a prototype implementation of such DBus API, but we ended up in a circle between "there's not enough time spent on the LVM DBus API because nobody's using it and thus it's not high priority" and "nobody's using the LVM DBus API because there's not enough time spent on it". To break this circle and get from the deadlock, we would like to make the installation process use the LVM DBus API and thus pioneer its usage for others and make sure it is maintained, improved and considered a high-enough priority by the LVM team due to a real usage in an important component of the system/distribution. The reasons for why the installation process could be the first one to use the new API are the following facts: * anaconda+blivet are written in Python so the performance of the LVM DBus daemon prototype also written in Python shouldn't be an issue * anaconda+blivet only do basic operations with LVM in the installation process so we could start with this limitted scope * blivet uses libblockdev as its backend and libblockdev is modular having the LVM functionality as a plugin which can be replaced with a new plugin using the DBus API where possible while keeping the old/current plugin as a backup solution if it turns out the LVM DBus API is * not production ready even for the installation use case. This results in a wonderful Contingency plan (see below). == Scope == * Proposal owners: implement the LVMDBus libblockdev plugin (vpodzime), make sure the LVM DBus daemon is packaged for Fedora and production ready for the installation use case (jbrassow) * Other developers: N/A (not a System Wide Change) * Release engineering: N/A (not a System Wide Change) * Policies and guidelines: N/A (not a System Wide Change) * Trademark approval: N/A (not needed for this Change) -- Jan Kuřík Platform & Fedora Program Manager Red Hat Czech s.r.o., Purkynova 99/71, 612 45 Brno, Czech Republic _______________________________________________ devel-announce mailing list devel-announce@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel-announce -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
