Dr. Ew Posted October 17, 2019 Share Posted October 17, 2019 This happened once before, and I had the capability to restore the cache from a very recent backup, which was faster than potential troubleshooting, so I am unsure of how to correct now. I have 3 HBA's in this particular server. One HBA failed. I replaced the HBA. Once booted again, with the replaced HBA, 4 disks #'s have been re-assigned, so the cache pool shows 4 drives in their correct slots, and 4 slots which have no device. I put the drives back in the correct corresponding order, and unraid informs me it will wipe my drives upon spinning up the array. How do I correct this now? Quote Link to comment
jpowell8672 Posted October 17, 2019 Share Posted October 17, 2019 unRAID identifies the drives by there serial number, you sure you have them assigned correctly? Quote Link to comment

How do I correct this now? Stop the array, 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, re-enable Docker/VMs if needed, start array. Alternatively you can also do a new config and reassign all devices, then check parity is already valid before starting the array. Quote Link to comment
