Extended/Logical partition with parted

Question

I have already partition/installed server and its partition is like following

# parted -l Model: ATA TOSHIBA THNSNJ51 (scsi) Disk /dev/sda: 512GB Sector size (logical/physical): 512B/512B Partition Table: msdos Disk Flags: Number Start End Size Type File system Flags 1 1049kB 324GB 324GB primary 2 324GB 405GB 80.5GB primary lvm 3 405GB 406GB 1074MB primary xfs boot 4 406GB 512GB 106GB extended 5 406GB 512GB 106GB logical lvm 

Following is output of lsblk

# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 477G 0 disk ├─sda1 8:1 0 302G 0 part ├─sda2 8:2 0 75G 0 part ├─sda3 8:3 0 1G 0 part /boot ├─sda4 8:4 0 1K 0 part └─sda5 8:5 0 99G 0 part ├─cl_m1-root 253:0 0 89G 0 lvm / └─cl_m1-swap 253:1 0 10G 0 lvm [SWAP] 

blkid command is saying this /dev/sda5 as Type LVM2_member, which i couldnt understand

# blkid /dev/sdb1: UUID="2019-03-18-19-33-14-00" LABEL="my" TYPE="udf" PTTYPE="dos" /dev/sda3: UUID="eaf7cef9-4107-4d30-ac51-80e678897888" TYPE="xfs" /dev/sda5: UUID="7x2wp0-KTva-jJ7y-copN-brui-jzJC-6gVqJc" TYPE="LVM2_member" 

Now i want to create same partition with parted command but i dont know how to partition last part sda4 and sda5(/ and swap), I tried below

# setup partition table on disk parted -s /dev/sda mklabel msdos parted -s /dev/sda mkpart primary 1049k 324G parted -s /dev/sda mkpart primary 324G 405G parted -s /dev/sda mkpart primary 405G 406G parted -s /dev/sda mkpart extended 406G 512G parted -s set 2 lvm on parted -s set 3 boot on parted -s set 4 lvm on 

I am new to sys admin stuff, excuse if i missed some obvious point

Answer 1

Read Logical Volume Manager documentation. The partitions flagged as lvm are physical volumes, containing logical volumes.

Partitioning is not needed for most LVM using systems. Let the installer carve out a /boot partition, then create and extend volume groups with entire disks.

Answer 2

I run following to achieve it

part /boot --fstype=xfs --onpart=/dev/sda3 part pv.192 --onpart=/dev/sda5 --size 1 --grow volgroup centos pv.192 logvol / --fstype="xfs" --name=root --vgname=centos --percent=90 --grow logvol swap --fstype="swap" --name=swap --vgname=centos --size=2048 --grow TOTAL=`parted -s /dev/sda unit GB print free | grep Free | awk '{print $3}'` parted -s /dev/sda mkpart primary xfs 1049k 324GB parted -s /dev/sda mkpart primary xfs 324GB 405GB parted -s /dev/sda mkpart primary xfs 405GB 406GB parted -s /dev/sda mkpart extended 406GB ${TOTAL^^} parted -s /dev/sda mkpart logical xfs 406GB ${TOTAL^^} parted -s set 2 lvm on parted -s set 3 boot on
