Solution

Today after restoring my snapshot to one of my Alibaba Cloud ECS instance; I was unable to access my website from my browser. I tried a lot of this and that but all in vain. Then finally, after much research, I read that the connection was getting refused by my Web Server, in my case the Apache Web Server.

Once I restarted, the Web Server, the website was accessible now.

Command to restart the Apache Web Server:

For Ubuntu:

 sudo service apache2 restart  

For RHEL/CentOS 7:

 systemctl restart httpd  

[SOLVED] - Fix Corrupt NTFS Parition In Ubuntu Using ntfs-3g, Without Using Windows OR fsck

Since yesterday, I've been trying to backup my hard drive using Clonezilla but without any success. Twice I got the following error, when I tried to backup my full hard drive by using Clonezilla.

ntfsclone-ng.c: NTFS Volume '/dev/sda6/' is scheduled for  a check or it was shutdown uncleanly. Please boot Windows or fix it by fsck

& I know why this issue has cropped up. Few days back I used GParted to expand my main ext4 partition that has Ubuntu installed on it by using a chunk from another NTFS partition.

 >> SOLUTION:

Here's what worked for me. Open your terminal [CTRL+ALT+T]:

1. First list all the partition in your hard drive.

 df -h  

You should be getting a list of parition as shown in the image below. In my case, the NTFS parition is '/dev/sda6.'

 2. Now unmount the NTFS partition using the following command. Please note, the command is 'umount' and not 'unmount.'

 sudo umount /dev/sda6  

3. If you do not have ntfs-3g installed, you can install it using the following command:

 sudo apt-get install ntfs-3g  

4. Now run the ntfs-3g command to check/repair your corrupt/problematic NTFS partition:

 sudo ntfsfix -b -d /dev/sda6  

here,

• b: clear-bad-sectors -- Clear the bad sector list 
• d: clear-dirty -- Clear the volume dirty flag

5. If the CHECK/REPAIR operation is successful, you should be getting a message as shown in the image below:
