Mirrored Cache Drives Down UNRAID 6.12.4

[daytona235]

Hi all, 

It's been awhile. Server has been working great for so many years with zero issues. 
Looks like somehow both my mirrored SSDs (running BTRFS) for my cache which also holds my docker stuff crashed at the same time. 

Any chance of a recovery? All help is appreciated. 

Thank you in advance. 

Diag info included.

If the log tree is the only issue this may help:

 

btrfs rescue zero-log /dev/sdm1

 

Then re-start the array

Thank you - I also noticed the SSD's were reporting 100 degrees temp. 
I stopped the server to let everything cool down - think my network closet may need some more cooling. 

@JorgeB could you please point me to any primer on BTRFS recovery? 
I am not a linux maven have learned along the way - been using UNRAID for like 25 years now. Love this tech and it makes me learn new stuff. 

Thanks again

If the command above didn't work post new diags after array start.

Totally worked. THANK YOU. 

Any idea what caused this and how do I prevent this? 
also should I execute this commend ever so often? 

Planning to move to 2x NVMI 1TB soon - with ZFS. Any advice? 

Thank you

Difficult to say other than possibly an unlcean shutdown.

No, only if there's a problem with the log tree

It's a good idea.
