Created attachment 217522 [details] zpool doesnt boot Hi there, I have a FreeBSD 12.1-STABLE running on VMWARE with one disk. Then I added two more disks to expand my pool. BTW I already did it many time with no issues. I ran: # zpool status pool: zroot state: ONLINE status: Some supported features are not enabled on the pool. The pool can still be used, but some features are unavailable. action: Enable all features using 'zpool upgrade'. Once this is done, the pool may no longer be accessible by software that does not support the features. See zpool-features(7) for details. scan: none requested config: NAME STATE READ WRITE CKSUM zroot ONLINE 0 0 0 gpt/disk0 ONLINE 0 0 0 errors: No known data errors # zpool add -f zroot da1 # zpool add -f zroot da2 # zpool status pool: zroot state: ONLINE scan: none requested config: NAME STATE READ WRITE CKSUM zroot ONLINE 0 0 0 gpt/disk0 ONLINE 0 0 0 da1 ONLINE 0 0 0 da2 ONLINE 0 0 0 errors: No known data errors # reboot Then my system doesn’t boot anymore, i got the following error: See errors in my attachment I can import my pool with no problems using the lived, but I could not fix it. Seems a bug after 12.1-STABLE. Please, anyone can take a look ok that? Thanks.
