Lanjut ya ...
Kalau sudah extend Logical Volume-nya /home ... langkah selanjutnya ada me-resize File Systemnya, menggunakan command :

Code: 
[root@core ~]# resize2fs /dev/centos_core/home

Lalu cek hasilnya menggunakan :

Code: 
[root@core ~]# df -h

Selesai. Semoga bermanfaat.
 
langkah terakhirnya muncul message gini @GPLHosting :
#
Code: 
[root@core ~]# resize2fs /dev/centos_core/home
resize2fs 1.42.9 (28-Dec-2013)
resize2fs: Bad magic number in super-block while trying to open /dev/centos_core/home
Couldn't find valid filesystem superblock.
# terus df -h tetep gak ada perubahan
Code: 
[root@core ~]# df -h

Kalau dicek yang 100GB udah ada ya :
[root@core ~]# fdisk -l

berarti untuk disatuin ke direktori ... /home nya yang belum berhasil ya @GPLHosting
sambil tetep ngoprek dan cari informasi sana sini :D
saya pakai cloudlinux + disk lvm, apakah perintah resize2fs gak support ya ?
 
GPLHosting said:
Kalau pakai resize2fs muncul error spt itu, maka filesystemnya bukan ext3 atau ext4.

Itu CentOS 7 ya? Kl iya, mgkn pakai xfs, coba dicek dulu pakai command:

Code: 
[root@core ~]# mount | grep centos_core-home
Click to expand...
iya saya coba dulu ..
ini pakai centos 7 diinstalin CloudLinux, jadi nya ya cloudlinux .. hehehe
 
GPLHosting said:
Kalau hasil pengecekan memang benar pakai XFS, maka untuk me-resize XFS nya gunakan command :

Code: 
[root@core ~]# xfs_growfs /dev/mapper/centos_core-home

Lalu kalau sudah selesai, cek lagi pakai df -h

Semoga sukses :D

Terimakasih atas panduannya dan sabar menuntun, hehehee
Tapi .. space yang sebelumya larinya kemana ya ? ko gak kesatuin sama yang 100GB seakan space yang lama dibanti sama space yang baru, apa emang gitu ya ?
