The problem is that libvirt (and probably qemu) are built against librbd1. If you remove librbd1, those get removed too. > So, I am curious why libvirt-bin has a depencey on librados2/librbd1 ? qemu needs it for obvious reasons. libvirt needs it to manage it's (rbd) storage pools. > Also, how come we get rid of this issue ? > Ceph-deploy should not remove any package other than ceph's. Purge could skip the libraries that may have other dependencies, but then it's a purge-lite. Honestly I thought it skipped them for that reason but we probably changed it at some point because it (also confusingly) wouldn't remove librados etc... sage -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
