Avamar: File Level Restore - Failed to Determine the Partition Type

FLR error message

FLR Failed to determine the partition type on Linux VMs with GPT partitioned with mixture of Linux and Logical volumes partitions:

Disk layout evidence

Run the following command on the VM guest: fdisk -lu and blkid:

fdisk -lu
Disk /dev/sda: 70 GiB, 75161927680 bytes, 146800640 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: gpt
Disk identifier: xxxxx-xxxx-xxxx

Device      Start       End   Sectors  Size Type
/dev/sda1    2048      4095      2048    1M BIOS boot
/dev/sda2    4096    980991    976896  477M Linux filesystem
/dev/sda3  980992 146798591 145817600 69.5G Linux LVM

blkid output

Shows partitions sda2 and sda3 are Linux file system and Logical volumes partitions respectively:

blkid
/dev/sda2: UUID="xxxxx-xx-xxx-xxxx-xxxx" TYPE="ext2" PARTUUID="xxxxx-xx-xxx-xxxx-xxxx"
/dev/sda3: UUID="xxxxx-xx-xxx-xxxx-xxxx" TYPE="LVM2_member" PARTUUID="xxxxx-xx-xxx-xxxx-xxxx"
/dev/mapper/vg00-lvroot: UUID="xxxxx-xx-xxx-xxxx-xxxx" TYPE="ext3"
/dev/mapper/vg00-lvopt: UUID="xxxxx-xx-xxx-xxxx-xxxx" TYPE="ext3"
/dev/mapper/vg00-lvvar: UUID="xxxxx-xx-xxx-xxxx-xxxx" TYPE="ext4"
/dev/mapper/vg00-lvwab: UUID="xxxxx-xx-xxx-xxxx-xxxx" TYPE="ext4"
/dev/mapper/swap: UUID="xxxxx-xx-xxx-xxxx-xxxx" TYPE="swap"
/dev/sda1: PARTUUID="xxxxx-xx-xxx-xxxx-xxxx"

Unsupported mixed partition types on GPT disks

• When a disk uses a GPT label, FLR supports only one partition type per disk: either LVMs or Linux file systems.
• FLR does not support disks that contain mixed partition types in this configuration.
• When a disk uses an msdos label, the FLR process ignores any partition with the boot flag and mounts the VM successfully even when the disk contains mixed partition types.
