Hello,

 

Today I went to update my OS and when I did all of my docker's disappeared completely. So I rolled back to the previous OS and realized the reason the dockers disappeared might be because I have 2 drives that were completely unmounted now (assuming one was the cache drive, I am not sure what the other drive was though). I remounted them but not sure what to do from here. These are my SSD drives. 

 

Is there a way to figure out which drive should go in which slot to re-start the array without losing data? I am worried about trying to put the array back together and it rebuilding and I lose everything. 
 

Logs attached. 

 

Thanks

They appear to be the same filesystem, did you have a pool?

Yes i think so but not 100%. I setup the server like two years ago and havent had to do anything like this to it since setup so problem is I dont remember. I am not 100% they were both cache drives either. Is there a way to see what they were before and then should I reslot them and start the array?

 

Post the output of:

btrfs fi usage -T /mnt/disks/name_of_the_UD_mountpoint

you can see the name by clicking on the + sign

That doesnt seem to tell me if it was a cache drive before it got taken off of the array etc though. Unless I am missing it.

How do I do run that command? I am trying to run it in terminal but it just says no such file or directory. Do i replace "Name of the ud mountpoint" with something else?

Got it : What am I looking for here?  Is this just to see if they were both caches in a pool together?

Yes, they are in a pool, with the array stopped reassigned them both to cache, there can't be any "data on this device will be deleted" warning after the devices, then start array.

You need to unmount from UD first if they are mounted with the array stopped, just need to unmount one of them.

Great that worked! Thanks so much!

 

Now back to the updating question. Did I do something wrong before? I just hit update to update to 6.90 and when it restarted thats when all of this happened. Do I need to do something differenT?

Cache shouldn't be unassigned after updating, but you're not the first to report this, note that it's normal to be unassigned if you downgrade back to v6.8.
