Linux server expand disk size

Oracle Cloud - Linux server expand disk size

Extend your disk from the storage server 1st. in this case we are using Oracle Cloud so we have extended in OCI console
fdisk -l

[root@ebs121db1-mylocal-com ~]# fdisk -l
WARNING: fdisk GPT support is currently new, and therefore in an experimental phase. Use at your own discretion.

Disk /dev/sda: 50.0 GB, 50010783744 bytes, 97677312 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 1048576 bytes
Disk label type: gpt
Disk identifier: A21E6499-33C5-401E-9330-8331C0E94D2C

You can see that disk is resized and it's visible in operating system level. next is we need to extend it.
resize2fs /dev/sdb

[root@ebs121db1-mylocal-com ~]# resize2fs /dev/sdb
resize2fs 1.45.4 (23-Sep-2019)
Filesystem at /dev/sdb is mounted on /u01; on-line resizing required
old_desc_blocks = 19, new_desc_blocks = 32
The filesystem on /dev/sdb is now 131072000 (4k) blocks long.

[root@ebs121db1-mylocal-com ~]# df -h /u01
Filesystem      Size  Used Avail Use% Mounted on
/dev/sdb        492G  260G  209G  56% /u01

/u01 mount point size is changed.

htop is not default install and it's not part of default repo so when we try to install htop it throw this message
yum install htop

yum-config-manager --enable ol7_developer_EPEL
yum-config-manager --disable ol7_developer_EPEL
