I know this question maybe very elementary in nature, so if someone can show me a guide to do it and think this thread is repetitive, please edit it at your convenience. I found out that on my Redhat system, the /home is mounted on a LVM with a xfs file system on /dev/mapper/rhel_home/ partition that is about 200GB in size. The problem is now that I want to separate this partition into 4 50GB large partitions and mount /home on one of them and mount some other directory on the other partitions. How do I go to do that? I can't use gparted, so I'd prefer to do it though the shell. here is the result of the command:[root@localhost ~]# vgdisplay -v    Using volume group(s) on command line.  --- Volume group ---  VG Name               rhel  System ID               Format                lvm2  Metadata Areas        1  Metadata Sequence No  4  VG Access             read/write  VG Status             resizable  MAX LV                0  Cur LV                3  Open LV               3  Max PV                0  Cur PV                1  Act PV                1  VG Size               232.34 GiB  PE Size               4.00 MiB  Total PE              59479  Alloc PE / Size       59463 / 232.28 GiB  Free  PE / Size       16 / 64.00 MiB  VG UUID               400oqQ-ClvP-Vdmi-D8Nh-ib4t-Knhs-fAhPjP  --- Logical volume ---  LV Path                /dev/rhel/swap  LV Name                swap  VG Name                rhel  LV UUID                b9IZNi-zMmG-angt-slI7-WYIg-0pJZ-bOARHT  LV Write Access        read/write  LV Creation host, time localhost.localdomain, 2016-09-21 09:58:47 -0700  LV Status              available  # open                 2  LV Size                15.75 GiB  Current LE             4032  Segments               1  Allocation             inherit  Read ahead sectors     auto  - currently set to     8192  Block device           253:1  --- Logical volume ---  LV Path                /dev/rhel/home  LV Name                home  VG Name                rhel  LV UUID                LoxHKf-atFU-Q246-cfMq-3ToY-o0jX-POnZg0  LV Write Access        read/write  LV Creation host, time localhost.localdomain, 2016-09-21 09:58:48 -0700  LV Status              available  # open                 1  LV Size                166.53 GiB  Current LE             42631  Segments               1  Allocation             inherit  Read ahead sectors     auto  - currently set to     8192  Block device           253:2  --- Logical volume ---  LV Path                /dev/rhel/root  LV Name                root  VG Name                rhel  LV UUID                eQdCo3-fPr0-Nh0y-8HAy-VBEE-uZyr-3qBsSs  LV Write Access        read/write  LV Creation host, time localhost.localdomain, 2016-09-21 09:58:50 -0700  LV Status              available  # open                 1  LV Size                50.00 GiB  Current LE             12800  Segments               1  Allocation             inherit  Read ahead sectors     auto  - currently set to     8192  Block device           253:0  --- Physical volumes ---  PV Name               /dev/sda2       PV UUID               JGq039-2zfz-RJms-UI20-xVM9-R0xZ-LfRQ7S  PV Status             allocatable  Total PE / Free PE    59479 / 16
