Sysadmin

I am sorry if this the wrong community to ask in, while I have been on Lemmy for more than a year now, I am still learning my way around, and this seems like a relatively active community in a relevant area.

Right, on to my questions!

I am planning to build a NAS over the summer, at the moment all of my personal photos are stored on a single mechanical 2TB Seagate drive that is about 4 years old.

I have other media on another drive that is older but larger, all in all I expect that I have about 8TB of data that I care about.

I am working as a 365 admin, and have been the main Linux admin at my last place of work, I am also a hobby photographer in my spare time.

Currently, I am looking at using either the N4, the N3 or the N5 from Jonsbo, the N4 is a beautiful case!

I am thinking of running four 6TB drives in a softraid like this:

Linux > MDAM (raid 5) > LVM > ext4

My thinking is that I will probably need to migrate to new drives every X years or so, and with the LVM, I can just add a new external (larger) drive to the VG, and move the LV from the old drives to the external drive, remove the old raid drives from the VG, put in new drives, setup MDAM, add the raid to the VG and move the LV back to the raid.

Am I overthinking this? this NAS will be my main media machine and will probably see a decent ammount of use over the years.

I have thought about setting up OpenMediaVault or TrueNAS as the OS, but having never run them, I wonder if they will be as flexible as I want them to be.

I am currently considering just running Debian and setting this up from the terminal, but I am not a super fan of SMB settings in the terminal, I did consider using cockpit as a web admin tool once it is setup to monitor the system, can I do the SMB config from that?

I am apprehensive about a manual SMB config, as the last time I did it, it was a weird mess for the team who had to use it...

I am more familiar with AMD hardware over Intel, and I am looking at the old AM4 plattfrom, but what I don't know is how much power a homebuilt NAS will use in standby or when active.

The first email of my day was sent to our head of HR asking what their hiring projections were for the next 6 months-1 year (usually I just get 1-2 months advanced notice) so I can shore up our tech stock

After decades of using the standard mouse cursor in Windows, and loosing track of it more and more as displays and resolutions grew, I have finally changed it to black and increased the size of it one step.

I find it so much easier to locate my cursor across my 1440p monitors, it is just clearer what is going on.

In the office I use a turqoice cursor, and at home I use the black cursor, it is a slight annoyance to get used to it, but wow, it is fantastic!

From a simple KeePass database to enterprise credential management solutions—what’s your setup at work?

Today I announced on the company wide Slack channel that, effectively immediately, we were rolling back to Windows XP. There were cheers! and then a lot of disappointment when I said it was just April fools Lmao

I was gifted a R720xd by work (yay!) and want to install a spare 3060 I have. Does any one know of a power cable and advice? Do I hook the power to the riser, the card, both?

Luckily the RCE only works if the device is domain joined which is against Veeams Best Practices.

Silly question: Having CNAMEs for A records just makes sense, but why can't we have a PTR redirect?

I go to investigate, and they had managed to plug the HDMI cable of one monitor into the other monitor.

I was recently looking for broken links on my websites using ahrefs tool, but it kept asking for money. I realized how easy what they were doing is to implement, so I did it myself.

That's how I made crawlr. It will recursively search all of the urls on your website save them into a csv file with their status code and let you know how many urls are broken.

It is written in go and is extremely fast. It takes a couple of seconds to index a couple hundered of urls.

Give it a ⭐ if you like it

As IT leaders move away from VMware, they face a critical decision: do they stick with traditional storage architectures, or is now the time to finally unlock the full potential of an infrastructure that converges virtualization, storage, and networking technologies?

Early convergence efforts centered on hyperconverged infrastructure (HCI), where storage ran as a virtual machine under the hypervisor, commonly called a vSAN. While adoption has lagged behind traditional three-tier architectures, recent advancements have significantly improved vSAN, making it worth reconsidering by addressing past shortcomings.

Hi all

I have been searching high and low but I think my search game is too weak. I am looking for a tool (similar to Uptime Kuma) that can monitor multiple systems via their own APIs, to centralise the status of these devices. Ex:

a) I have a sensor system that monitors a whole bunch of sensors across multiple locations. This system has an API that uses a secret key + api key for auth, and I can get the status of the sensor via the api. The idea is that the central dashboard shows the status, if offline, the control room personnel can log into the sensors system itself and determine root cause.

b) I also have a system to which a whole bunch of A/V equipment is connected, and via it's API I am able to view the status of multiple devices on the A/V equipment network. I want to also see on the status of these devices on my central monitoring system.

I don't care about doing root cause analysis via the central monitoring system, I just want the statuses which can action a person to check via the control system of that particular service.

All my searches come back with hits of systems that can monitor whether my APIs are up and running, but that is not what I want. Does anyone have any ideas? Preferably opensource, but definitely self-hosted/on-prem hosting. TIA

Please share your tips and tricks with me. I would love to hear them and use them.

Any feedback is welcomed.

I have been self-hosting for a while now with Traefik. It works, but I'd like to give Nginx Proxy Manager a try, it seems easier to manage stuff not in docker.

What are industry best practices for this stuff? Do you want a separate fabric for dev and prod? Just separate zones?

My company doesn't connect any fabrics (1 switch=1fabric) and it seems inefficient and a giant pain in the ass, as we move hosts around like we're getting paid for it. What do all of you do?
