Hey,

I'm new to Unraid, and I wanted to setup an NAS. The Problem is that my Drives are unmounted. So how do I mount them? I have already Zeroed out all my hard drives, and read a lot of the forum. I dont get it working, can anybody help me?

If you haven't formatted the disks in the array yet then they have no filesystem to mount.

 

Assuming these disks have no data yet, go to Array Operation and format them.

thanks, but unfortunately the option is grayed out.

Perfectly normal. Check the box that acknowledges "Yes, I want to do this" and it will become available.

 

We make it a multi step process to format drives because too often if someone has file system corruption the first thing they want to do is format the drive to make it mountable and then they think parity will restore their files, when the correct thing to do is a file system check. Formatting replaces the table of contents with a blank version, and it effects the parity drive as well, so it makes recovering data much harder or impossible.

 

In your case, you genuinely DON'T have a valid filesystem yet, so check the box and apply the format.

Thank you, its working now!

I have a drive that has already been formatted but its unmountable, using the gui I tried to run xfs repair.

If we use the above example screen shot, I want to try practicing mounting good drives manually. How would I do it ?

In this scenario I want to try and mount disk 2, would this be the correct example ?

>mkdir /tempxfs
>mount /dev/md2 /tempxfs

 

or 

>mkdir /tempxfs

>mount /dev/sdb /tempxfs

I am little lost of how do I know which drive is disk 2

I get these errors when trying to mount using the SDB example

/tempxfs: wrong fs type, bad option, bad superblock on /dev/sdi, missing codepage or helper program, or other error.
       dmesg(1) may have more information after failed mount system call.

I am currently in MAINT mode.

Why do you think you want to do this? You don't want to mount array disks independently or you will invalidate parity.

Could you give us more details? What was the output from xfs repair? Is the disk mountable now? Just start the array in normal mode and all mountable array disks will be mounted.

 

Attach diagnostics to your NEXT post in this thread.

As a heads-up as to why someone might want to do this, there's a Spaceinvader One video where I think people are picking up on this idea: 

 

I've currently got a "dirty log" and when checking the file system on a drive an unsure what to do.

Click the fix log button.

Now the not so proud owner of a 12TB lost+found share, and that's all there is on the drive. Bugger!

That's the only option if the filesystem didn't mount.

Linux 'file' command might be able to tell you what kind of data is in each file so you can try to open it in an appropriate application to identify it.

 

Simpler to restore from backup.
