here is my unraid 7 unassigned device

 

 

trying to add the same disk as the pool, but I'm having difficulty to do it 

for example

the guid isn't really matching the one from zpool import output

 

Any idea how should i proceed as next step? 

don't want to copy the data out to backup disk and import again, as it will take me several days just copy data out 

 

also when i add a pool with fs auto, i cannot add log or cache disk either, are they required when importing pool?

Please post the output of:

 

zpool status -LP

 

[ytwytw]

Here is the result

 

Do I create a new pool with the identical order?

How does the log and cache gonna work?

No need, make sure the pool has been exported first:

zpool export truepool

Then create a new pool with 9 slots, no subpools, just the main pool, assign all 9 devices, start the array, the pool should correctly imports, including logs and cache, but if it doesn't post the diagnostics.
