[linux-lvm] LVM complains about /etc/lvm/cache/.cache it created

[linux-lvm] LVM complains about /etc/lvm/cache/.cache it created

[Thomas Deutschmann]

Hi,

while reworking how we activate LVM in Gentoo's genkernel initramfs init
script, I tested some commands at boot in the following order:

# /sbin/lvm vgscan
# /sbin/lvm vgchange -ay --sysinit
# /sbin/lvm vgmknodes --ignorelockingfailure --verbose

The last command (vgmknodes) will output

>     Failed to load existing device cache from /etc/lvm/cache/.cache

I can delete this file (/etc/lvm/cache/.cache), re-run the command twice
and on the second call, after cache file was recreated by LVM, the error
is back.

So this looks like LVM is creating a cache it cannot use by itself?!
