Would it be possible to have a fast, but less-safe mode for lvm2? Right now lvm2 always enumerates every single block device on the system, which is hugely wasteful when one knows exactly which block devices are the PVs that will be affected by the operation. “Less-safe” means that this is intended for use by programs that know what they are doing, and that know that e.g. clustering is not in use. Using this in conjunction with clustering is a bug in the application. Commands that enumerate devices will, in fast mode, only return LVs on the provided list of PVs. Attempts to modify an LV on a different PV would fail as of the LV did not exist. -- Sincerely, Demi Marie Obenour (she/her/hers) Invisible Things Lab
