Hi,
today I cleaned my NAS PC, after booting the pool called tank disapeard. I tried to import the pool in the GUI, but just got the error message: “[EZFS_IO] Failed to import ‘tank’ pool: cannot import ‘tank’ as ‘tank’: I/O error”.
Under more Info is written:
` Error: concurrent.futures.process._RemoteTraceback:

The above exception was the direct cause of the following exception:

I googled the error and found the way of importing in CLI with zpool. When I tryed to import the following error came up:
I even tried with -fF but still the same error. What could I do to get the pool back online?
