Adding new LVM partition

First, assign a new disk to the system.
In our case, i have create a LVM partition called /dev/sdb1 with LVM type.

Show existing and create new Physical Volume

[root@FPXAPPBGID01 ~]# pvs   PV         VG              Fmt  Attr PSize   PFree   /dev/sda3  VolGroup00_ROOT lvm2 a--  133.75g      0 root@ABC ~]# pvcreate /dev/sdb1   dev_is_mpath: failed to get device for 8:17   Physical volume "/dev/sdb1" successfully created

You may use “pvs” or “pvdisplay” or “lvmdiskscan” to show the PVs

[root@ABC ~]# pvdisplay   --- Physical volume ---   PV Name               /dev/sda3   VG Name               VolGroup00_ROOT   PV Size               133.75 GiB / not usable 0   Allocatable           yes (but full)   PE Size               4.00 MiB   Total PE              34241   Free PE               0   Allocated PE          34241   PV UUID               XAf2JX-hFZf-aLGh-sqgt-1bB9-eE1J-WggwUL   "/dev/sdb1" is a new physical volume of "150.00 GiB"   --- NEW Physical volume ---   PV Name               /dev/sdb1   VG Name   PV Size               150.00 GiB   Allocatable           NO   PE Size               0   Total PE              0   Free PE               0   Allocated PE          0   PV UUID               g6QVGr-2zlF-Otqc-o24I-UKsS-yYkd-rOe8Ee

Create Volume Group

[root@ABC ~]# vgcreate VolGroup01_APPL /dev/sdb1   Volume group "VolGroup01_APPL" successfully created [root@ABC ~]# vgdisplay   --- Volume group ---   VG Name               VolGroup01_APPL   System ID   Format                lvm2   Metadata Areas        1   Metadata Sequence No  1   VG Access             read/write   VG Status             resizable   MAX LV                0   Cur LV                0   Open LV               0   Max PV                0   Cur PV                1   Act PV                1   VG Size               150.00 GiB   PE Size               4.00 MiB   Total PE              38399   Alloc PE / Size       0 / 0   Free  PE / Size       38399 / 150.00 GiB   VG UUID               gWatkt-DrJy-TEKI-aHbv-36sr-gXLx-zWt33i   --- Volume group ---   VG Name               VolGroup00_ROOT   System ID   Format                lvm2   Metadata Areas        1   Metadata Sequence No  5   VG Access             read/write   VG Status             resizable   MAX LV                0   Cur LV                4   Open LV               4   Max PV                0   Cur PV                1   Act PV                1   VG Size               133.75 GiB   PE Size               4.00 MiB   Total PE              34241   Alloc PE / Size       34241 / 133.75 GiB   Free  PE / Size       0 / 0   VG UUID               S7DAGH-P2ei-6Hqt-CeXu-lcqT-x71G-Io5KJQ [root@ABC ~]# pvs   PV         VG              Fmt  Attr PSize   PFree   /dev/sda3  VolGroup00_ROOT lvm2 a--  133.75g      0   /dev/sdb1  VolGroup01_APPL lvm2 a--  150.00g 150.00g

Scan and create new Logical Volumes

[root@ABC ~]# lvs   LV            VG              Attr       LSize  Pool Origin Data%  Move Log Cpy%Sync Convert   LogVol00_HOME VolGroup00_ROOT -wi-ao---- 20.00g   LogVol00_ROOT VolGroup00_ROOT -wi-ao---- 83.75g   LogVol00_TMP  VolGroup00_ROOT -wi-ao---- 10.00g   LogVol00_VAR  VolGroup00_ROOT -wi-ao---- 20.00g [root@ABC ~]# lvcreate -L150G -n LogVol01_APPL VolGroup01_APPL   Logical volume " LogVol01_APPL" created

Create file system

[root@ABC ~]# mkfs.ext4 /dev/VolGroup01_APPL/LogVol01_APPL [root@ABC ~]# mkdir /appl [root@ABC ~]# mount /dev/VolGroup01_APPL/LogVol01_APPL /appl [root@ABC ~]# df -h Filesystem                                 Size  Used Avail Use% Mounted on /dev/mapper/VolGroup00_ROOT-LogVol00_ROOT   83G  2.7G   76G   4% / tmpfs                                       12G     0   12G   0% /dev/shm /dev/sda1                                  243M   35M  195M  16% /boot /dev/mapper/VolGroup00_ROOT-LogVol00_HOME   20G  172M   19G   1% /home /dev/mapper/VolGroup00_ROOT-LogVol00_TMP   9.9G  154M  9.2G   2% /tmp /dev/mapper/VolGroup00_ROOT-LogVol00_VAR    20G  250M   19G   2% /var /dev/mapper/VolGroup01_APPL-LogVol01_APPL  147G  188M  140G   1% /appl [root@ABC appl]# lvs   LV            VG              Attr       LSize   Pool Origin Data%  Move Log Cpy%Sync Convert   LogVol00_HOME VolGroup00_ROOT -wi-ao----  20.00g   LogVol00_ROOT VolGroup00_ROOT -wi-ao----  83.75g   LogVol00_TMP  VolGroup00_ROOT -wi-ao----  10.00g   LogVol00_VAR  VolGroup00_ROOT -wi-ao----  20.00g   LogVol01_APPL VolGroup01_APPL -wi-ao---- 149.00g   ß0 means the drive is “open” or in-use

And lastly, make sure you add it to /etc/fstab to make it auto mount across reboots.
