How to extend logical volume disk on linux centos 7
Check the disk size
[root@localhost ~]# df -h

devtmpfs 3.9G 0 3.9G 0% /dev

Check the volume group size
[root@localhost ~]# vgs
VG #PV #LV #SN Attr VSize VFree
centos 1 2 0 wz--n- 48.00g 0
vgdata 1 1 0 wz--n- <1024.00g <124.00g
[root@localhost ~]#
Check the volume group vgdata size
[root@localhost ~]# vgdislpay vgdata
-bash: vgdislpay: command not found
[root@localhost ~]# lsvg vgdata
-bash: lsvg: command not found
[root@localhost ~]# vgdisplay vgdata

Check the logical volume size
[root@localhost ~]# lvs
LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert
root centos -wi-ao---- 43.00g
swap centos -wi-ao---- 5.00g

[root@localhost ~]#
Extend the logical volume (data lv)
[root@localhost ~]# lvextend -l +31743 /dev/vgdata/data
Size of logical volume vgdata/data changed from 900.00 GiB (230400 extents) to <1024.00 GiB (262143 extents).
Logical volume vgdata/data successfully resized.
[root@localhost ~]#
Resize the disk / logical volume
[root@localhost ~]# resize2fs /dev/vgdata/data
resize2fs 1.42.9 (28-Dec-2013)
Filesystem at /dev/vgdata/data is mounted on /data; on-line resizing required
old_desc_blocks = 113, new_desc_blocks = 128
The filesystem on /dev/vgdata/data is now 268434432 blocks long.
