Power out - after reboot, appdata missing. Diagnostics attached

[volcs0]

Found my unRAID without the array started - after a reboot some time today when I wasn't home. I started up the array and found that Docker services weren't starting. Then I found that appdata is missing. The share and folder are just gone.

Diagnostics attached. Any help is appreciated. I have an appdata backup from September 6, so not that current but not nothing...

Thanks for the help.

 

Edit: Seems that my cache drive is no longer. I need to figure out what happened to it. Presumably that's the problem.

Did you have a cache drive before this, or was it always the UD mounted disk (ie: was the Kingston SSD your cache drive)?

Since your appdata and system shares are cache-only you must have had cache. And your docker.cfg specifies cache for docker.img.

^^^ Thanks. (I was being lazy)

 

Which means that you'll need to unmount the drive from Unassigned Devices, stop the array and reassign it as a cache pool.  Will probably fix you right up.

Sorry to not follow up - yes, I took out the cache drive, blew the dust off everything and put it back in. It showed up - I backed everything up this time, and it seems to be working. But I'm wondering if I should replace it (1TB Samsung EVO 870).

 

The only warning I get is about the cache drive being hot - then it goes back down again. This happens during any heavy use.

 

Thanks for your help.

How hot? You can set the warning temperature for a specific disk by clicking on it to get to its page. SSDs are expected to run hotter than HDDs.
