[Resolved] Amazon EC2 Redhat 7 using 6GB for the root space

I create new server with 10GB of HDD, but when i check on the command line, the root space only show 6GB. I'm using t2.micto and Redhat 7.0, disk type: XFS.


- xvda1: boot partition
- xvda2: root partition

Fix Step:
We have instance A with the volume VA.

1) Stop the current instace A
2) Snapshot the current volume VA of the instance A
3) Start the instance A
4) Create new volume with 25GB by using the snapshot of volume VA then we have new volume VB
5) Attach the new volume VB to the instance A as default (/dev/sdf)
6) From the ssh console, i use the lsblk command to list the disk.
# lsblk
7) Using the xfs_repair to repair the /dev/xvdf2
( yum install xfsprogs)
# xfs_repair /dev/xvdf2


8) Continue as the image below


9) Remove the /dev/xvdf2, remember the start of this disk then we will create the new one with the same.


10) Using XFS command to repair the /dev/xvdf2 again.
# xfs_repair /dev/xvdf2
11) Use the lsblk command to test the disk space again.
12) Stop the instance A again
13) Deattach the volume VA from the instace A
14) Attach the volume VB to the instance A (/dev/sda1)
15) Start the instance then using the command to check the root space.
# df -lTh
# lsblk

CLEANING UP THE ZABBIX DATABASE

My Zabbix database size increased a lot in the last few months and since my disk was running out space, I decided to clean up the old events from the database. Looking at the database tables, the biggest one was  history_uint , which holds the items history data – over 400 millions of records and over 30 Gb of disk space before the clean up. Since deleting the old records from this table directly would be a very slow process, I decided to create a new table and insert the latest records from the  history_uint  table and then just replace the old table with a new one. Since this is not an offical procedure, use it at your own risk. Environment: Zabbix v2.2 MySql 5.1 – InnoDB with  innodb_file_per_table=ON Step 1 – Stop the Zabbix server Step 2 – Open your favourite MySQL client and create a new table CREATE TABLE  history_uint_new  LIKE  history_uint; Step 3 – Insert the latest records from the  history_uint  table to the  history_uint_new table First you need to de

Stuxnet Trojan - Memory Forensics with Volatility | Part I

Hình ảnh
Stuxnet could be the first advanced malware. It is thought that it was developed by the United States and Israel to attack Iran's nuclear facilities. It attacked Windows systems using a zero-day exploit and It was focused on SCADA systems in order to  affect critical infrastructures... Also, it may be spread from USB drivers. It is necessary a squad of highly capable programmers with depth of knowledge of industrial processes and an interest in attacking industrial infrastructure to develop this malware. Kaspersky Lab concluded that the sophisticated attack could only have been conducted "with nation-state support" and a study of the spread of Stuxnet by Symantec says that it was spread to Iran (58.85%), Indonesia (18.22%), India (8.31%), Azerbaijan (2.57%).... Thanks to Malware Cookbook we can download a memory dump from an infected host with this malware in the URL below:  http://www.jonrajewski.com/data/Malware/stuxnet.vmem.zip Ok, let’s go.
