Old hardware may not be suitable for games, but it is enough to install a host machine and some clients. A pc can meet the following requirements. One dual-core CPU (64-bit) 4 GB memory 80 GB hard drive Boot from CD, DVD, or USB boot One Network Card Note that the CPU must be 64-bit because Debian no longer supports the 32-bi

mdmonitor on Debian, Ubuntu or Linux Mint In Debian or Debian-like systems, mdadm can be installed using aptitude or apt-get: # Aptitude install mdadm In Ubuntu, you are required to configure Postfix MTA to send email notifications. You can jump over. In the Debian system, the installer displays the following explanation to help us determine whether to install the root directory to the RAID array.

. Therefore, the desktop version is duplicated. UNetbootin is not needed for a long time. I forgot how to use it. Finally, I selected Ubuntu, 1004_live, and then selected the desktop ISO file, and selected the U disk I want to use to start. For so long, I did not find that this Tsinghua-like USB flash disk is 4 GB, haha, the bigger the better. Then copy the ISO file of the desktop to the USB flash disk. Then restart the system. This operation was successful. After the startup, select default. Af

0 + 1 as long as one hard disk is damaged, another hard disk of RAID 0 in the same group will also stop operating, with only two hard disks operating, with low reliability. Therefore, RAID 10 is far more commonly used than RAID 01. most retail boards support RAID 0/1/5/10, but RAID 01 is not supported. 2.
