Unmountable: Wrong or no file system

[Alpha.Ars]

 

One of my drives died and I replaced it. The drive rebuilded completely and once it was done I got this error: (Unmountable: Wrong or no file system). I started following the spaceinvader's video and saw I had a strage report in the xfs_repair status: 

Phase 1 - find and verify superblock...
bad primary superblock - bad CRC in superblock !!!

attempting to find secondary superblock...
.found candidate secondary superblock...
verified secondary superblock...
would write modified primary superblock
Primary superblock would have been modified.
Cannot proceed further in no_modify mode.
Exiting now.

 

I'm not sure what I'm supposed to do at this point. Could someone guide me a little ?

Run xfs_repair again without -n or nothing will be done.

[Alpha.Ars]

I runned it again without anything:

ERROR: The filesystem has valuable metadata changes in a log which needs to
be replayed.  Mount the filesystem to replay the log, and unmount it before
re-running xfs_repair.  If you are unable to mount the filesystem, then use
the -L option to destroy the log and attempt a repair.
Note that destroying the log may cause corruption -- please attempt a mount
of the filesystem before doing this.

I will try following the video since this message is similar to the message shown in the video at: 6:56.
I'll update when I have something.

[Alpha.Ars]

I ran the xfs_repair with -L and got verry little files back.

post new diagnostics

Sorry, I did not see I got a reply. 
I went for an old backup I had laying somewhere and thought is was good enough.

Thanks for your help!

I am also having an issue of Unmountable: Wrong or no file system on Disk2 of my array.  Currently, it is being emulated, but regardless of what I have tried it will not mount..  I attaching my diagnostics on here if someone is able to read and understand what is going on I would appreciate it.

Check filesystem on disk2, note that both parity and disk1 appear to be failing.

What do you mean? Disk2 is not disabled in those diagnostics. It is unmountable though. Good thing it isn't being emulated since your other failing disks would be involved with that.

Disk3 doesn't look too good either.

 

Was disk2 disabled and did you perhaps rebuild disk2 using those other failing disks? That could certainly explain why it is unmountable.

 

How did you let yourself get to this point where you have multiple failing disks?

 

Do you have Notifications setup to alert you immediately by email or other agent as soon as a problem is detected?

 

Do you have backups of anything important and irreplaceable?
