Hi!

Yes! I also see these weird device names, but I don't have a good
explanation for it, so that I'm stupid to think deep into it.
Thanks!!!

So, the broken device path/symbol is only related to udev, lvm just
get the device list from udev DB right?

Do you think such issue can make LVM think the disk is missing?

Thanks! From this, I've learned how import device filter setup is!
