A possibility I just debugged for a non-booting system.
If there is a partition table on the underlying device then that
device is not detected as an LVM1/2 member in at least one version of
udevd, and won't be seen nor turned on automatically by the
systemd-udev code.

I have my ZVOL on my NAS exposed as LUNs. The initiator were switched off
and for unknown reason I found my NAS switched off as well.
It had run for long and I feared the worst (CPU/motherboard/etc). Instead
once powered up everything started to work again but the LUNs that

so it might be that metadata is corrupted somehow and hence the pvs program
doesn't recognize that partition as physical volume?
That may explain why lvmdiskscan reports physical disks (by just looking at
the partition type 8e)

Am I correct?

If you have lvmetad running and in use then the lvm commands ask it
what the system has on it.
I have seen on random boots fairly separated systems (rhel7 versions,
and many years newer fedora systems) at random fail to find one or
more pv.s
I have disabled it at home, and in my day job we have

Hi all,
I sought the web for the error " Failed to find physical volume
"/dev/zd96p5"." but the closest discussion in the LVM archives I found was
one of mine back in 2014
https://listman.redhat.com/archives/linux-lvm/2014-June/msg00016.html
This time though it seems pvs fails to find the
