What happened:
I had two LVM volume groups. I thought that I removed one specific LVM volume group with blivet-gui. But after doing this both LVM volume groups are not showing up any more. Maybe I made a mistake, maybe something else went wrong.
Current state:
I did not reboot my computer yet, and everything still works. But blivet-gui does not show any LVM volume groups any more.
Questions:
- How can I recover the LVM volume group and the LVM logical volumes?
- Will I not be able to start the computer any more after reboot if I do not recover them?

Note how fedora-home and fedora-root are still mounted.
I still see the three LVM pysical volumes with pvs, but only with the -A option:
# pvs -A
PV VG Fmt Attr PSize PFree
/dev/mapper/luks-23d92739-0aa1-4ffc-af64-18fc524bad5b fedora lvm2 a-- <487.85g 0

/dev/mapper/luks-f29fc668-9a4c-4b15-87f2-c6981be1e840 fedora lvm2 a-- <232.88g 0
As you can see above, also the VG fedora is still mentioned.
But vgs does not show the fedora VG:
# vgs fedora
Volume group "fedora" not found
Cannot process volume group fedora
# vgs -a
#
The command vgcfgrestore gives me quite some output:
# vgcfgrestore -l fedora

If I try to use vgcfgrestore, I get:
# vgcfgrestore fedora
Volume group fedora has active volume: home.
Volume group fedora has active volume: root.
Volume group fedora has active volume: swap.
WARNING: Found 3 active volume(s) in volume group "fedora".
Restoring VG with active LVs, may cause mismatch with its metadata.
Do you really want to proceed with restore of volume group "fedora", while 3 volume(s) are active? [y/n]: n
Restore aborted.
I answered the question Do you really want to proceed with restore of volume group "fedora", while 3 volume(s) are active? with n.
So it seems that I have to make the volumes inactive. But I guess that I will not be able to use my system when I do that. How would you recommend to proceed?
