Media Server Storage Hardware Reconfiguration

Our media server has reached 89% utilization and needs storage expansion. The storage makeup on the server uses Logical Volume Manager (LVM) and software RAID called mdadm. I can expand the storage by swapping out the hard drives with the least capacity with new hard drives with a larger capacity like I have previously done.

I thought I try something different this time around. I would like to switch from LVM to ZFS, an LVM alternative that is very popular with modern mass storage systems, especially with TrueNAS.

All filled with 8 drives

Before I can attempt the conversion, I will first need to backup all of the content from the media server. The second issue is that I needed more physical expansion space on the server to house more hard drives. The existing housings are all filled except for a single slot, which is going to be insufficient.

A related issue is that I no longer have any free SATA slots available for the new hard drives, so I purchased GLOTRENDS SA3116J PCIe SATA Adapter Card with 16 SATA Ports. Once this is installed, I have more than enough SATA ports for additional storage.

PCIe SATA Card Installed

One downside of the SATA card is that it is limited to PCIe 3.0 x1 speed. This means data transfer is limited to a theoretical maximum of 1GB/s. Given that the physical hard drives top out at 200MB/s, I don’t think we need to be too concerned about this bottleneck. We will see in terms of practical usage in the future.

I am so lucky to have extra SATA power cables and extension cables laying around and my 850W existing power supply has ample power for the additional hard drives.

How do we store the additional hard drives with a full cabinet? I went to Amazon again and purchased a hard drive cage, Jaquiain 3.5 Inch HDD Hard Drive Cage 8X3.5 Inch HDD Cage. I did not have to buy any new hard drives yet, because I had plenty of old hard drives laying around. After I put together the cage with 8 really old and used hard drives, it looks something like this:

With this new additional storage, I am now able to backup the media content from my media server. However, before I do that there is one last thing that I need to do, and that is to experiment with an optimal ZFS pool configuration that will work with my content and usage. I will perform this experimentation with the additional storage before reconfiguring the old storage with ZFS. Please stay tuned for my findings.

After booting the system with 16 hard drives, I measured the power usage and it was hovering around 180W. This is not too bad, less than 2 traditional incandescent light bulbs.


Addendum:

During my setup, I had to spend hours deciphering an issue. My system did not recognize my old hard drives. After many trials, I finally narrowed down that the GLOTRENDS card is not compatible with an old 2TB Western Digital Enterprise Drive. This is the first time that I came across SATA incompatibilities.

There is another possibility that these drives were damaged by the usage of an incorrect modular power cable. I found that these drives also do not work with my USB3.0 HDD external dock as well. This gives additional credence that the physical drive has been damaged.

The troubled drive with the SATA card

All my other drives worked fine with the card.

Another discovery is that not all modular power cables will work with my ASUS ROG STRIX 850W power supply. Initially, I thought I would use an 8-pin PCIe to 6-pin adapter along with a 6-pin to SATA power cable designed for Corsair power supplies.

PCIe Power Adapter from Amazon
OwlTree PCI-e 6 Pin Male to 4 SATA 1 to 4 SATA Female Power Supply Splitter Supply Cable for Corsair Modular RM650X RM750X RM850X RM1000X

Using the above cables will cause the power supply not to start. I had to hunt for the original cables that came with the STRIX power supply.

Learned a lot from rejigging this media server. My reward is to see my server boot up with 16 hard drives and 2 NVMe SSD drives recognized. I have never built a system with so many drives and storage before.

What is the Chinese Government?

Recently I have been faced with questions and accusations on how corrupt and dictatorial the Chinese government is to its population. Most of these comments come from people who have not visited and experienced China. Their conclusion largely stems from the feeding of Western mainstream media.

I provide this post as a source of “alternative” information so that anyone can get a quick introduction of what is the Chinese government and how is it being run?

Take a look at this TED talk by Eric Li. He quickly summarizes the differences between the Chinese government that are based on merit versus one that is based on votes practiced by the West.

Don’t people in China wish to live in a democratic country?

Answered by YN Chen on Quora on Nov 5, 2023

I am a Chinese, have studied in the UK and traveled to many countries.

For me, China is democratic – probably even more democratic than western countries.

Of course, I am referring to the original meaning of the word democracy – the power of the state belongs to the people and the people have the right to rule the government.

Nowadays, democracy in the west often refers to multi-party competition, where the ruling party are elected by universal suffrage.

But this approach has some significant problems. As voters are ordinary people who has no specialized knowledge on managing the country, the core competitiveness of the election process becomes the ability to publicize public opinion, personal affinity, and persuasion, which have little to do with whether they can actually formulate and implement policies well, but are more relevant to the resources of the society and the media operation behind them.

In the west, the rule of the people is in a single choice question of political preference, and the frequency of being able to make a choice is once every four years. If you are the minority voter, you will not be able to get a satisfactory result in those four years.

In contrast, China’s “democracy” works like this:

  1. A huge system of officials that everyone can enter by studying and taking exams – from the smallest local township government to the central government, all within the same pyramid-tested promotion system. For Chinese graduates, it is a very common career selection to pick an official position related to their major from an open government list, take a test on logic and issue processing skills, and become a government official. All newcomers need to start from the basic positions and get enough practical results before they are internally elected with promotion.
  2. The criterion value of the government affairs is “people first”. The most important judgment dimension is whether they can improve the life of the majority and satisfy the people.
  3. Public opinion monitoring and feedback mechanism. All levels of government have set up channels to receive public opinion, such as emails, petitions reception, or social media. For every actual problem, the government must give feedback or specific plans within a period of time; and after a period of time, they must do regular follow-up visits to ensure that the problem has been solved satisfactorily. All this is counted in the KPIs of government staff. If the people are not satisfied with this government’s response, they can complain to a higher level of government, which has absolute power over the next level of government, and the government department complained against will be penalized and monitored.

In China, the rule of the people is in the government’s “people first” evaluation criteria, and in the mechanism of feedback and resolution of specific issues that are highly valued. However, if your opinion is detrimental to the interests of the underprivileged, or if you are not looking for a solution, but simply venting your negative feelings and trying to get more people to share your negative feelings, then your opinion might be refused or ignored, or be deferred in to future considerations.

I think this is why people say: in the west, you can change the government, but you can’t change the policies; however in China, you can’t change the government, but you can change the policies.

Of course, both mechanisms have their own drawbacks. For example, since the core competence of universal suffrage is the ability of influencing public opinion, so having control of the media and enough money is almost equivalent to having a high probability of obtaining the highest power in the country; in China, it is very difficult to make the complex internal promotion completely transparent, and it is not easy for the people to monitor inefficiencies and corruption inside the system.

But for me and at least 80%+ Chinese people, the current one party Chinese government is still very satisfactory.

As for the so-called “Communist Party is not the same as government”: in fact, the CCP is not the same as the Soviet Union type of “communism”, for example, China has its market economy system and is running well. Actually when there is only one political party, the notion of party advocacy would be extremely weakened. In the case of China, people would tend to feel that the Chinese system is more like a parliamentary system even within the government. China is a country with a secular culture, and ideology discussion is not really that important, what matters to this government council is simply about insisting with the people-oriented value, and making people living in better lives.

To be honest, I think that the vast majority of the world’s people don’t care about politics.

People care more about their own lives – whether they can live healthy and happy lives with the people they love, whether the society is fair, safe and free, whether they can enjoy their civil rights as a human being, whether their problems can be solved and whether their dreams can be realized.

Also, I agree that China is better for ordinary people, small and medium-sized entrepreneurs to live in, but not for the extremely rich guys. If you are a rich tycoon or celebrity and has no interest in benefiting ordinary people, then the Chinese government might supervising you with very strict rules, you will have more freedom and power in the West.

But as for me, China is not bad.
