Best video on internet on how to create a raid 1 on linux by far. Keep that up man. Love from Spain.

[@Tuxattack8094]

Just got done setting up raid 1 as my network drive thanks to this video! Extremely helpful!!

[@avidowlaty2576]

Thank you, sir. This is the most beginner-friendly video I have ever watched on KZbin. Thank you so much.

[@KnowledgeSharingTech]

Glad it was helpful!

[@pigseye2]

You are an amazing teacher! I really appreciate how thoroughly you explain everything. You gained a new subscriber!

[@bobafett2598]

Fantastic! Easy to follow, slow enough to understand and practical example after that. Well done, very helpful!

[@KnowledgeSharingTech]

Glad it was helpful!

[@PMuXeA]

As a rather newcomer to linux this was pure gold. Thank you!

[@mickcrerar559]

One of the best, and I've watched many vids on setting up a Linux RAID. Thank you for taking the time.

[@davekendk89]

Excellent tutorial it was very easy to follow, the only difference i had was that when using fdisk i didn't have "Linux raid autodetect (fd)" I substituted "Linux Raid (29)"

[@KnowledgeSharingTech]

Thanks for sharing

[@blueandgreen1465]

Very clear and efficient! Thanks!

[@Rezendes]

Thank you, just setup a raid 1 of my OS drive using this and rsync with cron (3 copies of the OS).

[@cypherLabs]

Subscribed your channel. You are very kind and explained each and every part of the commands you write. I was searching for a video to create a RAID with 2 dedicated drives and isolate my os drive. This is what i looking for. Thanks a lot, for this video.

[@KnowledgeSharingTech]

Glad I could help

[@rubenbermudez2445]

Excellente vidéo, je l'ai utilisée avec Debian 12 et elle a parfaitement fonctionné. Merci 👍

[@KnowledgeSharingTech]

Welcome

[@UnixGuy32]

Very good teaching,, Thank you very much

[@derMaex]

Very good explanation, thank you.

[@CryptoGearHQ]

Very well-done sir! I learned a ton. I would like to have my Linux boot disk mirrored like you did the aditional 2 hard drives in your system. Is it possible to do this in Linux? I have looked around but find no info on this. Thanks

[@alexxjumiii]

Grande bro,me has salvado la tarea!!

[@nordical6071]

[@saidbakr]

Indeed, Thank you very much!

[@KnowledgeSharingTech]

You're very welcome!

[@ramon1738]

Hello. Congratulations for the video. How do you manage to simulate the disk failure (minute 8:17 of the video)? Thanks.

[@luigitech3169]

thanks what i was looking for! what do you think about BTRFS for mirroring ?

[@aejazawte-m4t]

great video..! but i have one question what if i dont have GUI access, i want to perform all operations by CLI only?

[@fvntn]

Hello! How to transfer my /home folder to this new raid disk? Thanks

[@hystorycal8467]

so say if i wanted 6 8TB HDD in raid 1 i would put raid-devices=6 /dev/hdd0 /dev/hdd1 /dev/hdd2 /dev/hdd3 /dev/hdd4 /dev/hdd5 then everything past /dev/hdd0 would be redundant onto it?

[@Aera223]

@@hystorycal8467 yep, tho 6 drives are a lot for raid 1, maybe have 3 offline and ready, and start with 3 drives in the raid array

[@markusfassbinder8275]

thank you!

[@InnerFire6213]

If you reinstall your OS, will the raid setup be affected? Will the new OS recognise the existing array? In this case the raid array is being used for storage only, not the OS itself

[@melissastroud9238]

A lot of this info was useful until you used the gui to format and mount the raid volume. I am using ubuntu server with only the terminal interface. It would be helpful if you did all of it from the terminal interface.

[@albanliyoshi]

thx, i will try to make raid 1 with 2 HDD 1to... just to know, ne need to put the OS in this volume ? i just want to make a data volume in raid and OS system on another one HDD (linux OS on C, and RAID 1 on D + E)

[@johnny234511]

Thanks for the tutoriel!

[@KnowledgeSharingTech]

You bet!

[@vapon]

Don't we have to "remove" the failed drive from the array? What if the new hdd has different /dev/xxx e.g. based on your video sdd instead of sdc?

[@mrisakson]

what formatting option would you use if you wanted access from both linux and windows?

[@KnowledgeSharingTech]

Windows is more permissive when it comes to recognizing file formats. So go with exFat

[@tienphanalc]

Thanks sir!

[@KnowledgeSharingTech]

Most welcome!

[@ayshad5353]

Hi, thank you for this insightful tutorial. But something happened to me while I was testing this when I removed one of the disks, the name of my logical volume change from /dev/md0 to /dev/machine-name:0 what should be the reason ?

[@frenchytwitch733]

First time with Ubuntu so not sure if I'm missing something but I am only getting half of my 4GB drives partitioned after the "sudo fdisk /dev/sdb" input following all the steps after. Any tips?

[@paulkemna163]

What are the system requirements for mdam in a raid 1 mirror?

[@StefanoZamprogno]

Great video thanks! And what about to INSTALL the full linux system on a RAID1 / RAID10 sistem?

[@KnowledgeSharingTech]

You will need Hardware Raid for that

[@brandonlk98]

when you look at --detail, its gives you major and minor. what does this refer to?

[@Tubularjake]

Does anyone know if you can use a USB drive for the boot drive? I've been watching lots of videos to see where the OS is located. I think with Unraid the OS is located on a USB drive that lives permanently in one of your USB ports.

[@danielpaete6773]

Will you show us how to create a shared folder with multiple users to access to it with password restriction. Thank you very much.

[@5amba]

how to create a raid 1 for the already existing boot drive?

[@EmpInd]

This is something I´ve been looking for a long time, I wonder if this can be applied for an already boot driver too!

[@Chayou-qz3wt]

Hi! What I have to do if fail os hd?

[@aureliuse3469]

hello, may i know how if the PC is broken ? how can i get my file back?

[@vishnurocks5780]

Sir your video is good , But as a novice .... I want to do it .... Sir I connected two physical hdd of 4TB each , and I directly connected to a desktop with a bootable pendrive medium loaded with Ubuntu22 latest server OS , I wanna make it Raid1 with mirroring So I had selected custom install first , So it is showing the hardrives are in brts format Now what to do sir 2)Also after watching this video I got gut feeling that i could have also made like this ..... !! But the problem is after making raid1 mirroring ... can I install Ubuntu22 latest server OS after making RAID1 ? PLEASE advise and Answer 1 & 2

[@marksd2167]

When installing Ubuntu Desktop, can you create a raid1 to install Ubuntu on?

[@KnowledgeSharingTech]

Not in the way I show in this video. You have to create a HW Raid 1 to be able to install an OS on it. I will make a video soon on this. So stay tuned

[@Yousuf4CAVS]

does this persist after reboot. do they need to be added to /etc/fstab?

[@KnowledgeSharingTech]

It's a permanent configuration

[@user-iv2np3nk4k]

Perfect! Thank you.
