David Teigland	f5a669f314	pvck: repair should clear hints ... repairing a pv can cause the hint file to become incorrect	2020-09-02 14:21:17 -05:00
David Teigland	b400353c71	tests hints: update check for io count ... Running a reporting command on a VG now includes one additional read to check the mda_header for any change to the vg between scan and lock.	2019-11-26 16:52:28 -06:00
David Teigland	99ca06ca46	tests: hints check if strace exists ... avoid test failure if test system does not have strace	2019-05-21 14:24:57 -05:00
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	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
