You create a logical volume with the next command by specifying the new volume's name and size, and the volume group it will reside on: Now we need to create logical volumes on this volume group. After creating the last volume with -l 100%FREE, this can be accomplished by reducing its size with lvreduce -L -256M volume_group/ logical_volume. If a logical volume will be formatted with ext4, leave at least 256 MiB free space in the volume group to allow using e2scrub(8).If you wish to use snapshots, logical volume caching, thin provisioned logical volumes or RAID see LVM#Logical volumes.To list all your devices capable of being used as a physical volume: If you use Master Boot Record partition table, set the partition type ID to 8e (partition type Linux LVM in fdisk). If you use GUID Partition Table, set the partition type GUID to E6D6D379-F507-44C2-A23C-238F2A3DF928 (partition type Linux LVM in fdisk and 8e00 in gdisk).At this point you will diverge and doing all your partitioning with LVM in mind.įirst, partition your disks as required before configuring LVM. You will follow along with the installation guide until you come to Installation guide#Partition the disks. Nevertheless, it requires this separate boot partition. Create the partition /boot for BIOS systems irrespective of the partition table and create a Linux filesystem on it (partition type 8300 in gdisk). While this partition is already necessary for UEFI/GPT it is an additional partition for both BIOS/MBR and BIOS/GPT. Warning: /boot cannot reside in LVM when using a boot loader which does not support LVM you must create a separate /boot partition and format it directly.
