Package: lvm Version: 2.0
I have a Debian 9 XFCE system on a acer laptop with only 1 hard drive which was encrypted with LVM encryption during installation. After a recent reboot my system is stuck and no longer bootable with following messages: Volume group "acerv3-575t-vg" not found. Cannot process volume group acerv3-575-vg Save up waiting for suspend/resume device Volume group "acerv3-575t-vg" not found. Cannot process volume group acerv3-575-vg save up waiting for root file system device. Common problems: -Boot args (cat /proc/ cmdline) -check rootdelay = (did the system wait long enough?) -missing modules (cat /proc/modules; ls /dev) Alert!! /dev/mapper/acerv3-575t-vg-root does not exist.

Also per recommendation from same LiveCD prompt: root@acerv3-575t:/#update-initramfs -u update-initramfs: Generating /boot/initrd.img-4.19.0-9-amd64 root@acerv3-575t:/# (returns no error, but upon reboot, same original volume group not available message occuring). Any and all assistance is appreciated, I am a total newbie to linux and have been troubleshooting this for 2 days now and am without my main laptop.... I also per a recommendation from the initramfs prompt looked through dmesg log and did not see any errors or failures just the repeat inability to access the volume group. Package: lvm Version: 2.0
