Cache pool lost after upgrade to 6.9.2

[shafiq786110]

I have just upgraded to 6.9.2

All devices are recognised but my cache pool devices werent assigned to the Cache 1 and Cache 2 slots. 

When i select them they are now recognised as new devices and i get the warning that all data will be erased on them

What can i do to restore the cache without loosing the data on it?

I remember having this issue before, and ended up having to downgrade, restore all my docker containers and manually pull all the data off the drives before creating a new cache pool. But would rather avoid that if possible! 

Diags and screenshot attached

Thanks!

If Docker/VM services are using the cache pool disable them, unassign all cache devices, start array to make Unraid "forget" current cache config, stop array, reassign all cache devices (there can't be an "All existing data on this device will be OVERWRITTEN when array is Started" warning for any cache device), re-enable Docker/VMs if needed, start array.
