I'm trying to create a simple SFTP access /var/www/ Directory.

My problem:

When I log in via FTP, I get access to the /var/www/ -I also have access to the root directory.
I have changed it chroot Option as mentioned below YES but the problem still exists. I can not seem to restrict access just /var/www Folder.

Linux – Centos 6 – Move the folder to another hard disk while preserving the URL path

I have a dedicated server with a 4 x 500 GB hard disk running on Centos 6. My main hard disk became full and the MySQL server was shut down, so I had to temporarily free up space to fix the problem.

Below is the result for executing the following command parted -l

This /home/admin/domains/mydomain.com/public_html/Documents folder is large and I want to move it to another partition. (From "sda" to "sdb")

What is the correct way to keep the URL path to the files on the new partition?
mydomain.com/Documents

Linux – Centos / RHEL 7 – MBR with an extended partition> 2T

When I studied for the RHCSA, I tried to find an answer to a question that stuck in my mind …

To my knowledge, you can have a total of 4 partitions for MBR, which can not be larger than 2 TB … Now tell me what happens if the entire hard disk is 10 TB and the first 3 partitions are 1 TB in total. If your fourth partition is extended. Can it be the remaining 9 TB, as long as the logical partitions are <2 TB? Or is the extended also limited to 2 TiB.

Someone has answered with parted, what worked. However, I'm still looking forward to the limitations of an extended partition with MBR.
