Why is this idiot constantly losing his data? What's the point of using RAID?
>literally given free cool shit to fuck around with
He aint an idiot bruh. He is an entertainer with a decent knowledge of tech. He knows exactly what he is doing when he makes these videos.
He used literally the stupidest fucking RAID setup possible.
Like, I actually can't fucking believe it's so bad.
Not only that, but all their data is just jammed into fucking user folders instead of a properly organized content management system.
I use a 3-disk raid 5, am i fucked?
No, you're probably fine. As long as you have, y'know, actual backups.
Linus was using three RAID 5 arrays of eight 1TB SSDs.
That in itself is stupid, but it gets worse.
He then used software striping in Windows to pool the three arrays together to form a single 24GB software array.
That means that if any one of the three arrays failed, everything would be lost.
And he had no backups.
What a fucking dumbass.
I enjoyed their (biased) junkyard wars videos which I stumbled on but every other fucking video is "we need to build these machines to render 1500 videos a day".
Yeah, no thanks le gay earring renderman.
>I believe he needed the speed to have up to 10 people editing video at the same time.
A raid 10 would have been safer and faster he just didn't want to spend the extra money on drives. There's no excuse for using hardware raid. there's not excuse for using windows as a file server.
There's no excuse for not teiring your god damn data, I guarantee he doesn't need SSD speeds for everything they are doing, anything that isn't actively being used can sit on platter drives. Ready to use it? okay move or copy it to the fast storage to do your work.
This happend cause he was trying to do both and not spend a lot of money.
You just can't do that.
Oh also there's no excuse for not making real backups, A backup is not something you do AFTER you have a failure. in the video I heard him say "the server was the backup." NO NO NO NO.
The funny thing is I remember when they did the video about that system and I was like yeah that's going to fail, mind you it didn't fail the way I expected but they should really re-build it into something else.
>software RAID 0 on groups of disks set up as a RAID 5
>one of the RAID 5 groups somehow contained only 2 disks
I don't even
- linus fucking up by not having enterprise level storage array where everything is redundant
- three raid 5 into one stripe, retarded
- not being able to just swap failed HW for a new one
- all the false emotions, GEEZUS
Everyone always fails to mention he has since built a proper off-site backup server, he has been backing it up on another server, although at the time of the crash he was in the very early stages of doing the first back up, and most importantly, Linus was able to recover all his data. People act like he lost everything when he didn't lose shit.
He knows full well he should be using more reliable RAID configurations.
But 90% of what he does is "because we can, not because we should"
He put too much faith in hardware reliability and let his obsession for making it as fast as possible get in the way of fault tolerance.
He's not an idiot for losing his data. He'll be an idiot if he does the same thing again.
>He knows full well he should be using more reliable RAID configurations.
I actually doubt this, Linus is Tech Lite. He's like that one kid in the family who's slightly better with computers than the rest of the family. Relative to the average person he knows stuff but relative to someone in his field he's quite amateurish.
Oh I'm quite sure someone in the field of enterprise server grade RAID configurations would look at him as an amateur.
But at the same time I'm sure the thought of something a bit more reliable at least crossed his mind before he decided to build in favor of speed over reliability. He likely figured it would all be upgraded before component reliability came into play given how often he gets new hardware.
Nice vid, i watched it all
why cant we have less retared linus with somone who have personality and is not shilling so hard with ms and games
I am sure that his new multiple gayming ring would be better with kvm xen
And this is why you NEVER use onboard shitty raid.
Either go softraid (or better use something other than standard raid levels if you're going software) or a real hardware raid card.
NEVER use bullshit like 'Intel Matrix RAID'
He had a backup but it was old. Right at the beginning he said "in the middle of making a new backup".
Yes, his backup scheme was inadequate. From what I can determine the setup could have handled effectively losing one drive from each array without loss of data, but loss of multiple drives from a single array was not taken into account.
In the end the drives were not lost, the motherboard shat the bed resulting in bad data being sent to the RAID controllers probably corrupting the file systems before the RAID card shat itself completely and stopped being able to communicate with the drives.
File systems can be restored. That's probably the majority of what the file recovery guys did along with rebuilding the arrays correctly so that data could be taken off them again.
raid1 here, w/o swaps and buckups, how long until everthing fucks up?
How can you hate a guy who keeps an optical drive because it has Lightscribe?
I had both my drives fail once. That was fun, one of them lost its file system which I managed to restore and get most of my data off it, the other was pretty much just dead.
But they were PATA drives.
I should get around to backing up my server. Once I buy a couple of 4TB drives.
>Linus shills so much he's able to build a $30000 pc that has 2 cpus, 7 gpus, and water cooling just to see if it can support 7 different users simultaneously
Except it wouldn't in this case because having three drives with corrupted file systems on a single array would be equivalent to having three lost drives as far as the RAID controllers are concerned.
They wouldn't have been able to rebuild on their own.
Replacing the morbo wouldn't have magically restored everything.
"rendering" is a very common term for exporting the final result in video editors
since you have not just video, but also videos overlapping and other effects (like fading in and out), text elements, graphics elements
>RAID 5 consists of block-level striping with distributed parity. Unlike RAID 4, parity information is distributed among the drives, requiring all drives but one to be present to operate. Upon failure of a single drive, subsequent reads can be calculated from the distributed parity such that no data is lost.
He effectively had three hardware RAIDs and one software RAID going on.
Three RAID 5s, each with eight drives. These would have appeared as three drives to Windows.
These three drives were then assembled in a RAID 0.
Each of the RAID 5s could have lost a single drive without harming the overall array.
the RAID is not about the fucking filesystem, the controllers don't have a clue about file systems,
the controllers sole purpose is to rebuild the RAID array when it fails, if the filesystem fails this is OS / software related
Modern filesystems actually store backups of themselves in different portions of the drive so that if such a thing occurs you can run a utility to locate a backup of the filesystem and restore it.
>this fag spends/gets from shilling partners literally thousands of dollars for fancy storage solutions
>it fails within months
>I use a seagate harddisk I scraped from an old laptop 4 years ago and put into an external case
>it still works
If I did I sure as shit wouldn't use such a fucking atrocious storage configuration.
And I wouldn't put the server into a production environment without setting up an active backup system first.
These guys deal with tens or even hundreds of thousands of dollars of gear passing through their hands each year, and when asked about backups, Linus's response was "THIS SERVER IS THE BACKUP". How is your primary filestore that you work from a fucking backup?
Not the point though. The guy was claiming how his hard drive has lasted years and their server broke in months.
You can't compare the two cases when his HDD is connected every once in a while but their server is running 24/7 and getting smashed most days.
Nah he is still a retard
>no off site backup at all
>have been moved into the new office for MONTHS
that shit is inexcusable in any professional company and if he had a senior he should be fired for that alone.
Using Windows for disk management
Not using ZFS
I find it hard not to think that he does this shit just for the lols. He should know better, but maybe he doesn't. It's a fucking clownfiesta every time he makes a video that's not a review of a GPU/CPU/whatever.
I've actually been told horror stories of RAID cards that lasted years, and when they finally failed my professor who was working at a big company at the time had to search high and low for the same one that had been off the market for years.
I'm pretty sure a second disk is supposed to fail every time you try to rebuild with a new parity disk. It seems to always happen anyway.
Stick to at least double parity and use a proper fs.
>>52243066 Hey OP, This >>52243705
exactly. i would gladly watch him make an ass of himself day after day, the man has no pride and doesn't mind getting filmed for it. he's an actor first and a cable monkey second, and if you can't realize that, re-evaluate your brain.
