This happend to me around 2 weeks ago. For some reason, I decied to post this now.

I won the lottery, yey! I mean, bot really, but I am <19yo student, "less than junior dev" in my office, but sonce I am the only one who is capable of working with hardware, I was working month back as a sysadmin for a few days. Our last sysadmin was really good working but really, really toxic guy, so he got fired on a spot after argument with some manager or whatever, no big deal, we could have another guy hired in a week. But, our backup server literally was on fire, all data probably dead because bad capacitor or whatever. This was our only backup of everything at the time. Everyone in full fucking panic mode, we had literally no other working HW we could use for backup, but then comes me, intern employed on his first dev job for 3 months. That day I bought some HW for my own personal server at home (Intel NUC with some Celeron, 4GB DDR4 RAM and two 240GB SSDs for RAID 1. My manager asked everyone in the office for sollution how to survive next 4 days before new server arrives. People there had no idea what tk do and no knowedgle about HW, I just came from a break and offered my components for a week, since there was noone else who can work with HW, servers and stuff like this, manager offered me $500+HW cost if I, random intern, can make it work. I installed Debian on that little PC, created RAID1 from both SSDs, installed MySQL server and mirrored GIT server from our last standing server (we had two before one of them went lit 🔥), made simple Python script to copy all data on that RAID, with some help of our database guy copied whole DB from production to this little computer and edited some PHP so every SQL request made on our server will run on that NUC too. Everything after ±2 hours worked perfectly. Untill a fucking PSU burned in our server and took RAID controller with him in sillicon heaven next night, so we could not access any data unltill we got a new one. Thanks to every god out there, I was able to create software RAID from survived HDDs on our production server and copy all data from that NUC on the servers software RAID and make it working at 3 AM in the night before an exam 😂. Without this, we would be next ±40 hours without aerver running and we might loose soke of our data and customers. So my little skill with Linux, Python, MySQL and most importantly my NUC hardware I got that day running as a backup server saved maybe whole company 😂.
Btw, guess who is now employee of the year with $2500 bonus? 😀
Sorry for bragging and log post, but I was so lucky an so happy when everything worked out, good luck to all sysadmins out there! 👍

TL:DR: Random intern saved company and made some money 😂

Finally, I can play around with a proper server.
HP ProLiant DL380 G6 = dual 8-core Xenons @ 2.4GHz with 32GB RAM and 12TB / RAID1-0 of WD Purples (we happened to have them for some reason).
Already pissed at HP because they don't support JBOD and already pissed at myself for using CentOS, but other than that, enjoying the hell out of it!

And it's ALL MINE! ... Well, technically it's the org's, but it won't go into production for half a year and I'm the only one with the root access so, for now, it's MINE! 😅

Linux software RAID and LVM are pretty powerful.

Bought a new server case for my home file server / VM host. 3U with 16 hotswap bays. Had 2x software RAID1 mirrors already with everything on them. Inserted 2 new disks with system running. Created new RAID10 array using these, with their mirrors as "missing".

Created new physical volume. Extended volume group into it, then used pvmove to transfer every logical volume across. Shrunk volume group to no longer use the old RAID1 array, disassembled that array, added its disks to the new array... Now just waiting for the mirror disks to sync up.

All this, with the system and several VMs still running.

And with a backup, of course ;)

By far the stupidest thing I've done while drunk is setting up a layered LVM-over-RAID1 + striped LVM storage system *and* managing not to lose any data.

Next time I ran `lsblk` and realized how that structure came to be I kinda turned white.

Rant on me myself.

After being a professional coder (ie having a bachelor degree) for 11 years now, I finally have a decent and reasonable backup.

I use borg to backup to my raid 1, which is local, in my corridor near the ceiling. I use a Intel NUC with two external USB3 HDDs attatched. As I already had data on them, I went for a btrfs raid 1.

The second level of my backup solution is my brother. It's 50km to his flat. He's got a banana pi with my third HDD attached. I connect to his pi via VPN. The VPN is done via an AVM Fritz! Box. No ads, I just like those boxes (modem and router).
The backup is encrypted, of course.

Now, after ten years, I finally got a decent backup solution. Wow. This feels great! 😎

No actual data loss here, but the feeling of data loss.

After having my data scattered across several devices i decided to get a grip on it use a cloud. I'm too paranoid for a real cloud so i used a local nextcloud installation. That was done via docker and with a 2TB raid1-array.
I noticed that after restarting the server the cloud was somehow reset and pointed me to the setup-page, afterwards my files were already there. It did strike me as odd but i figured "maybe don't restart the server in the next time".
But i did restart it. And this time i had to setup the cloud again, but my files were gone. I got close to a heart attack, even though all those files weren't that valuable. I ripped one disk from the usb hub, connected it to my laptop and tried to mount it, but raid array. Instead i started photorec and recovered a bunch of files, even though their names were some random hex and i knew i'd spend my next weeks sorting my files. While photorec ran i inspected the docker container and saw that there were only 10GB of space available. After a while and one final df i found the culprit: the raid. For some reason the raid wasn't mounted at boot and docker created the volumes on the servers hard disk, same goes for the container data. After re-adding the disk to the hub i mounted the raid and inspected everything again. All my files were still there.

At no point did i lose my data, but the thought was shocking enough. It'd be best not to fiddle with this server in the next time.

To all devs that aren't allowed to BYOD, what Specs has the PC/Laptop your company provided?

Mine:
i7 3rd gen
IGP
16GB of RAM
500GB HDD in RAID1
and two 27" FullHD Screens

Aaayoo issya boi the OG rapper straight outta Compton, wassup?!

Nah, for real, though.: How are y'all doing? It has been a long time. I hope y'all are having a great time (can sense some peoples' incoming negative comments due to corona).

I built my completely new first gaming rig like a few weeks ago after my school laptop stopped showing any signals.

The specifications are the following.:
- Mobo: MSI B450 TOMAHAWK MAX
- CPU: AMD Ryzen 5 3600 (no iGPU)
- dGPU: KFA2 RTX 2070 SUPER OC
- 2nd dGPU: GTX 550 TI (this one gets a new rant/post)
- RAM: 2x G.SKILL Ripjaws V 8 GB 3600 MHz
- PSU: Be quiet 650 W (It was the platinum edition afaik. I originally bought the 600 Watt Gold edition, but somehow they sent me the 650 Watt for no additional charge... which is great for me haha)
- HDD: 2x 4TB NAS HDD in RAID1 configuration (to load all of my games around 2 TB right now. Got the two HDDs for 110 Euro including the SATA Data cables)
- SSD: One Intenso 240 GB SSD and a reused Samsung 256 GB SSD from my old broken Lenovo laptop
- Case: Be quiet Pure Base 500 black with a glass panel on the side

While building my first PC, it was one hell of a challenge. I knew how it all was working in theory, but to put it all together, practically, was a bit of a challenge, but it was a nice challenge. I learned a lot and have a performance gain I could only ever dream of.

I used to play my games first on a Toshiba satellite l750d laptop (around 40 fps in cs:go with the lowest gfx settings) and then on a Lenovo e51-80 laptop (around 30 fps max minecraft with no shaders and texture packs).

Now I play cs:go on Kubuntu with 400 fps at peak with ultra high graphics. It is unbelievable.

I couldn't trust the system when I turned on the fps display the first time I saw it.

FUCKING STACKOVERFLOW ASSHOLES.

This guy answered my question on security.stackexchange.com with an answer showing he clearly doesn’t understand that I’m asking if my RAID1 setup constitutes an appropriate backup. (I know that sounds stupid, I can post a link if anyone wants to see the specific circumstances).

I FUCKING KNOW RAID ISNT A BACKUP BUT THIS GUY IS LIKE “RAID 1, or mirroring, is definately [sic] considered a backup in corp IT”

Go suck a dick.
