Help needed, pve wont reboot after vgrenamed

[windpoint]

I changed vg name from pve to vg1
system wont boot after the change

# cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-4.4.6-1-pve root=/dev/mapper/pve-root ro quiet

under /dev/mapper/
I see VG1-root instead pve-root

Not sure where I can modify this setting.

Hey,

did you change /etc/fstab and /boot/grub/grub.cfg accordingly, for the second file, running grub-mkconfig might work, if not you have to make the changes manually. Why did you want to rename the VG in the first place?

Thank you, Hannes. This works for me.

BTW, the reason I changed it to vg1,vg2, is that pve is so confusing. it can be node or vg . I know it's stupid. But learned a lot...

can be useful if PVE don't boot anymore (wrong user modification update ... ) on the only SSD containing the PVE OS and VM disks.
A new PVE system on a dedicated SSD will boot without error about duplicated "pve" VG name.
