[skyyxy]

HI everybody. I have my own freenas 11.1U7 server in the office
CPU : intel g4560
RAM: 16G DDR4 NONE ECC*2
MB: ASROCK C236 WSI
BIOS VER. : P2.60
HDD: 6*HGST 6TB

Since 2days ago something wrong like the pictures when booting. I tried zpool import command but no lucky. So please anything I can do? Thanks advance.

How was your zpool constructed? What are you using as the boot media? If a thumb drive, try reinstalling to a new small SSD, and retrying the import.
