David Teigland	0aa51a2f61	hints: fix recreating hints from pvscan ... When aay was included in the pvscan --cache command, the activation part was complaining about the unusual state of the hint file since it had been recreated just prior.	2019-02-13 15:23:43 -06:00
David Teigland	5f102b3421	hints: invalidate when pvscan --cache sees a new PV ... An idea from Zdenek for better ensuring valid hints by invalidating them when pvscan --cache <device> sees a new PV, which is a case where we know that hints should be invalidated. This is triggered from systemd/udev logic, and there may be some cases where it would invalidate hints that the existing methods wouldn't detect.	2019-01-16 15:34:20 -06:00
David Teigland	7b5abc3fb1	hints: fix hint flock when using lvm shell ... also cmd->use_hints needs to be set for each shell command	2019-01-15 12:23:16 -06:00
David Teigland	6620dc9475	add device hints to reduce scanning ... Save the list of PVs in /run/lvm/hints. These hints are used to reduce scanning in a number of commands to only the PVs on the system, or only the PVs in a requested VG (rather than all devices on the system.)	2019-01-15 10:23:47 -06:00
