I followed this video step-by-step for setting up RAID.

I'm trying to RAID 2 4TB HDD using mdadm.

Everything seems to be going well until I do a reboot. After a reboot it says "Welcome To Emergency Mode" with options to view log files. I'm not exactly sure what I am looking for in these log files because there is a lot of information. One thing I saw that was interesting is in the attached. Basically, stating my RAID drive (/dev/md1) has failed.

I did test with umount and mount -a to make sure the /dev/md1 would mount to /mnt/raid1. In which it did before rebooting.

What am I doing wrong?

Is there any possibility to create the RAID with the installer?


Which Distro are you using?

I did get it to work now.

Thanks for the reply.

I have another issue with a SMB share, not being accessible anymore, that I will post in another tread.

It is considered good etiquette if you post what went wrong in the first place and how you solved it. It is polite for those who answered you and useful for new users having the same problem.

LQ is a community. It means information exchange goes both ways.

I'm not really a Linux guy so I wouldn't be able to explain it all that well. I learn from watching YouTube videos.

Dangerous practice - better to use a text guide like you were directed to in the duplicate post you made on this same subject. That way you can show specifically what you did, and proper advice can be given about particular steps.
I for one am not going to sit through 30 minutes of video on the off-chance there is something I can help with.
