Proxmox / PVE working with partitions and storage ( parted , lvm , mkfs , mount )

Assumptions:
Default installation of PROXMOX
4TB of storage Recommended : either 4x 2TB raid 10 , 2 x 4TB raid 1 or 3 x 2TB raid5 as /dev/sda
Unmounted /var/lib/vz
Partition 4 should be storage for the vm;s mounted as /var/lib/vz
show partitions including free space

Shell

parted /dev/sda print free

1	parted /dev/sda print free

remove partition 4

Shell

parted /dev/sda rm4

1	parted /dev/sda rm4

create partition aligned (optimal sectors) start at 1% and end at 100%

Shell

parted -a optimal /dev/sda mkpart primary 1% 100%

1	parted -a optimal /dev/sda mkpart primary 1% 100%

flag partition 4 as LVM

Shell

parted /dev/sda toggle 4 lvm

1	parted /dev/sda toggle 4 lvm

remove an existing logical volume called pve

Shell

vgremove pve

1	vgremove pve

create a LVM physical volume on the partition, with 2 metadata copies to increase fault tolerance of the metadata

Shell

pvcreate --metadatacopies 2 /dev/sda4

1	pvcreate --metadatacopies 2 /dev/sda4

create a logical volume group called hdd

Shell

vgcreate hdd /dev/sda4

1	vgcreate hdd /dev/sda4

Create the 3 logical volumes of 931.25 GByte volume called hdd1,hdd2,hdd3 on lvm group hdd

Shell

lvcreate -L931.25G -n hdd1 hdd lvcreate -L931.25G -n hdd2 hdd lvcreate -L931.25G -n hdd3 hdd

1 2 3

lvcreate -L931.25G -n hdd1 hdd lvcreate -L931.25G -n hdd2 hdd lvcreate -L931.25G -n hdd3 hdd

create a logical volume with the rest of the space, called datastore

Shell

lvcreate -l100%FREE -n datastore hdd <strong>Format the Logical Volumes to ext4</strong> we will use a 4K block size, since most modern drives use 4K sectors. [crayon-58a0d33c6350c963579198 lang="bash" title=""] mkfs.ext4 -b 4096 -L datastore /dev/hdd/datastore mkfs.ext4 -b 4096 -L hdd1 /dev/hdd/hdd1 mkfs.ext4 -b 4096 -L hdd2 /dev/hdd/hdd2 mkfs.ext4 -b 4096 -L hdd3 /dev/hdd/hdd3

Create a mount point and mount the Logical Volumes

Shell

mkdir /datastore mount -t ext4 /dev/hdd/datastore /datastore mkdir /hdd1 mount -t ext4 /dev/hdd/hdd1 /hdd1 mkdir /hdd2 mount -t ext4 /dev/hdd/hdd2 /hdd2 mkdir /hdd3 mount -t ext4 /dev/hdd/hdd3 /hdd3

Create media and backup folders on /datastore

Shell

mkdir -p /datastore/media mkdir -p /datastore/backup

1 2	mkdir -p /datastore/media mkdir -p /datastore/backup

Setup “fstab” to automatically mount

File: /etc/fstab

Shell
