LVM PVE GROUP not found at boot

[Wildcat]

Hello (Sorry for my terrible english ;op)
I fix all previous problems on my promox server its working good now.

But one error occur at each boot.

LVM PVE Group not found.

I fix this with :
vgchange -ay
exit
In initramfs each time i reboot the system
and all working good

I would like to fix it for future boot (Im not at home 24days on 30)
And my girlfriend are scared about writing this line each time we loose power ;o)

There is a way to automate it ?

Thx for your patience

you probably need to add "rootdelay=x" (where x is some value between 10 and 30 or so) to your kernel command line. this parameter tells the kernel to pause for x seconds before attempting to find and mount the root file system.

you can try it by hitting "e" in the grub menu on boot and adding it to the end of the line starting with "linux". once you find a suitable x, add it to the GRUB_CMDLINE_LINUX_DEFAULT line in /etc/default/grub and run "update-grub" to regenerate the grub config and make it permanent.

maybe the hardware needs a little longer to initialize.
you can try to edit /etc/default/grub and add "rootdelay=10" at GRUB_CMDLINE_LINUX_DEFAULT (i.e. GRUB_CMDLINE_LINUX_DEFAULT="rootdelay=10 quiet")
and then issue a # update-grub

this waits 10 seconds before trying to mount the root filesystem
