Hi, 

 

I'm having issues after a reboot with my server. Last month I replaced my main cache (called Cache) (which consisted of two 500gb sata SSDs (CT500MX500SSD1_1938E220145B and CT500MX500SSD1_21022C5622B7) with two new NVME 1tb SSDs (WD_Blue_SN570_1TB_224960400406 and WD_Blue_SN570_1TB_224960400170). After doing this I created a new secondary cache (called SecondaryCache) of just my old 500gb sata SSDs. 

 

In order to move the data from the old SSDs to the new ones, I:

 

1. Moved the data on the cache utilising the mover to the array
2. Confirmed no data was left on the old SSDs
3. Stopped Array
4. Removed Old SSDs from Cache
5. Added new SSDs to Cache
6. Added old SSDs to SecondaryCache 
7. Started Array
8. Moved data back from array to Cache utilising the mover (opposite of step 1) 
9. Set shares back to cache only where appropriate. 

 

This was all working fine with no issues, however after a reboot my Cache is showing a device configuration change where it is listing my new drives as incorrect. Can anyone help out? I'm confident all data is still on those drives, however I obviously want to be cautious when it comes to starting up the array again so some advice would be great.

I've uploaded a diagnostics log and an image of the warning.

 

My unraid version is : 6.11.5.

Additional info

Unassign both devices from the cache pool, start array, stop array, re-assign both devices to the cache pool, start array, and you're done.

Great, that worked for me. Thanks for your help.
