How to fix “Disk ‘lvmid’ Not Found” Error in Ubuntu

If you have been having trouble with the GRUB error “cannot find lvmid” in Ubuntu, our experts have your back.

This error message lets us know there is an issue with the Logical Volume Manager (LVM) setup.

LVM lets us manage storage across multiple physical disks, but the system may struggle to locate a specific logical volume identified by its UUID.

Common Causes and Solutions

Today, we will explore common causes and their solutions.

Missing or Corrupted LVM Metadata

The metadata describing logical volumes, volume groups, and physical volumes may be missing or corrupted.

Solution: Use LVM commands to check and repair the metadata.

sudo vgscan
sudo vgchange -ay


Incorrect LVM Configuration

The system may be looking for an LVM volume that no longer exists or has been renamed.

Solution: Verify the LVM configuration and update any references to the missing LVMID.

sudo lvdisplay
sudo vgdisplay
sudo pvdisplay


Disks Not Properly Recognized

Sometimes, disks are not recognized correctly, especially in complex storage setups or RAID arrays.

Solution: Make sure that all disks are properly connected and recognized by the system.

sudo fdisk -l
sudo lsblk

UUID Mismatch

If the UUIDs of disks or partitions have changed, the system might not find the correct volumes.

Solution: Update the `/etc/fstab` file and any other configuration files to reflect the correct UUIDs.

sudo blkid
sudo nano /etc/fstab

Kernel or Driver Issues

Issues with the kernel or storage drivers will prevent the system from recognizing LVM volumes.

Solution: So, update the system and ensure all drivers are up-to-date.

sudo apt update
sudo apt upgrade

Troubleshooting Tips

1. List all physical volumes, volume groups, and logical volumes as seen here:

   sudo pvs
sudo vgs
sudo lvs
2. Then, scan for all LVM volumes and activate them:

   sudo vgscan
sudo vgchange -ay
3. Now, list all disks and partitions to ensure they are recognized by the system.

   sudo fdisk -l
sudo lsblk
4. Also, list the UUIDs of all partitions and update the `/etc/fstab` file if necessary.

   sudo blkid
sudo nano /etc/fstab
sudo vgchange -ay
5. Finally, check system logs for any related errors or warnings.

   < sudo journalctl -xe
