I updated Unraid from version 6.12.15 to version 7.3.2 and now my cache pool is failing.

I had some document scans on there that I need but I can not individually mount the disk.
When I start the array it wants to format the disks.

The server is generally performing weird, last night I stopped the array and the GUI was populating and depopulating the MAIN tab with disks.
I am going to attempt rolling back to 6.12.15.

UPDATE: Downgrading back to 6.12.15 fixed my cache pool issue, something is not translating between version 6 and version 7.

Please post the diagnostics after array start (with 7.3.2)

Thanks for the reply.

I am in the middle of fixing a bunch of corrupted databases at the moment, I also lost a bunch of work from last night.

I will stick to 6.12.15 for the time being, might try the update again in a few months I don't have time to play around with this right now.
