Restart Woes - Parity Disabled, Wrong or no file system

[robr]

Hi Everyone,

I did a rennovation and moved office.  I shut my array down and it has been offline for a couple of months.

Just gone and fired it up...

I was in a world of pain initially as the system wouldn't boot - I was getting a "Kernal Panic" and system shutdown message.

I've since replaced USB key and updated and now its booting but Parity 1 is disabled, Disk 2 is disabled.

There have been no hardware changes - simply shutdown in storage.

I have attached the diagnostic.

Appreciate any help

Cheers

Rob

Disks were already disabled at boot time so we can't see what happened, but start by checking filesystem for disk2.

Hi There,

Thanks for above.  I ran the check and got the following per screen cap.

How do I Mount the filesystem to replay the log?

Thanks
Rob

It's not mounting so use -L.

Hi There Unraid Friends,

So I have run the check with -L... see the log attached.

Am I good to go?

I am nervous about being a noob and killing it....

That log looks good

 

Restart the array in normal mode and the drive should mount so see if you now have a lost+found folder on that disk.  That is where the repair process would put anything it found for which it could not figure out the correct name.   Your report looks very clean so there is a good chance no lost+found folder was created.

Hmmm... not there yet....

 

I still have Parity disabled and Disk 2 disabled and emulated.  Array not protected... not sure what to do next.

Appreciate suggestions!

The drives being disabled at this point is expected as nothing done so far would remove that state.

 

 

Some questions to try and decide what is best as the next steps:

• The repair on the emulated disk2 seemed to complete without anything suggesting corruption being logged but Disk2 is showing as basically being empty - is this expected? 
• Did you at any point try to format disk2?  If so was this while it was disabled or before that?
• Do you have backups of what should be on disk2?
• Is the drive that should be in disk2 showing up under Unassigned Devices?

[robr]

Thanks for helping....

• Disk 2 utilisation should have been very low... I think I just had the shares set up on fill up mode while I populate the array from other sources.  So it could be it was effectively empty.
• No format... ever.
• No backups.
• No, not in unassigned.

You need to re-enable the drives, you can do both at the same time:
