I had (4) platter disks and (1) SSD in a VG lvm. LV's were either on platters or the SSD, none were across both. Long story short, booted without SSD plugged in, and didn't need access to the LV's on the SSD. Needed to create a temporary LV on the platters, and got an error about not being able to create a LV while the VG was incomplete, with the SSD missing. Stupidly ran its advise of something like vgreduce --removemissing without reading vgreduce's man page. Thinking this would either be temporary for that boot, or I could just easily re-add it later. Still couldn't create the LV on the platter disks, so powered off and installed the SSD. I never added any LV's or made any other changes, so I just need to revert the metadata change, don't need to merge any changes in. pvs does show the SSD partition, with attribute missing. vgs does shows all 5 pv's, attribute partial. lvs dhows SSD thin pool, partial. Does NOT show the single thin volume that is within the SSD thin pool. Assuming that makes sense since the thin pool isn't activated. How do I permanently re-add the SSD PV to the VG, so the thin pool activates, and the thin volume is accessible? Is there an easy way I can compare the contents of metadata 315 and 319, verify 315 is exactly what I want, and reload 315 to be the current metadata on all PVs? Or is there a different way to go? I'm thinking "vgextend --restoremissing" might not be the way to go, since there's inconsistent metadata, but maybe that would be OK and it would just write a v320 to all 5 PVs. Should I manually dump the metadata based on offsets shown by pvck, find 315, assuming that has the correct information, and run vgcfgrestore on that file? Would that write like a new version 320 metadata to all 5 PVs? My system volume's etc doesn't have a backup of metadata 315. That etc backup was written on an ISO CD tmpfs and is now gone. I'm thinking the journalctl messages below mentioning "vgreduce --removemissing" and "--activationmode partial" are not at all what I want at this point.
