[TESTED] Extend and mount new disk (/dev/sdb/) into your folder in dev/sda – Centos 7

My server has a partition and the disk size just 38GB, whereas I need about 20GB more for save my new files. With this condition I think have just two options between extend the partition before or add new disk and mount it into a folder within my partition before. Then I discuss with my friend which way is the best and the faster, finally I choose the second option which is add new disk (new partition, basically it will named as /dev/sdb/, /dev/sdc/, etc) and mount it into my specific folder, let say I will mount it into /opt/lampp/htdocs/aset.

So, how to extend new disk and mount it into our custom folder? here are the steps. This solution was tested successfully in my server Linux Centos 7.

# Check your which one is your new disk
# you can check that with this
sudo parted -l | grep Error

# or this one
# just make sure the free size still 100%

# in my case I got /dev/sdb/
# so I started with this
pvcreate /dev/sdb

vgcreate diskaset /dev/sdb



# Chek these line!
# Alloc PE / Size       12799 / <50.00 GiB
# Free  PE / Size       0 / 0
# 12799 refers to Free PE or Alloc PE
lvcreate -l 12799 lv_diskaset diskaset

# Format the disk into XFS
# for "/disk/diskaset/" name it as you wish
sudo mkfs.xfs /dev/diskaset/
sudo mkfs.xfs /dev/diskaset/lv_diskaset

# Create folder for mount the disk
mkdir /opt/lampp/htdocs/aset/

# Mounting
mount /dev/diskaset/lv_diskaset /opt/lampp/htdocs/aset/

# Edit the "/etc/fstab" file for autostart when server startup
# Save
nano /etc/fstab/

# Add this line in the bottom
/dev/diskaset/lv_diskaset /opt/lampp/htdocs/aset        xfs     defaults        0 0

# Reboot your server

Finish, hope my solution above will help you sometime to extend and mount new disk into your custom folder for expanding storage in Linux Centos 7.

User REVIEW for PostgreSQL

Sometimes we need a database user only for review (read-only) purposes, this user used just for view some data or all data in a database, not for insert, delete and other CRUD activities in a database.

So if you want to create a REVIEW user in PostgreSQL, you have to grant access for SELECT and EXECUTE in a schema or database, and you have to grant access that user into schema itself. These script will help you out to create review user in PostgreSQL :

CREATE USER review WITH PASSWORD 'password_review';

GRANT USAGE ON SCHEMA schema_name TO review;

[SOLVED] Problem : Could not connect to server: connection timed out (0x0000274c/10060)

I have a problem when I tried to remote PostgreSQL Server (in Linux Centos) from my PgAdmin Client (in Windows), there’s an error message displayed on screen said “could not connect to server: connection timed out (0x0000274c/10060) is the server running on host and accepting tcp/ip connections on port 5432?”

I checked my firewall status with :
systemctl status firewalld

Condition : Not Normal

It said that my firewall status was Active: failed. From here I’m sure there’s problem with my firewall process, because if the firewall stopped successfully, the status will be inactive like this image below :

Condition : Normal


After tried many solution, I ended-up with this one :
systemctl unmask firewalld

Next step after run unmask syntax, I tried to restart my firewall and it runs flawlessly :). Hope this thread help you guys.
