Hello Experts, After updating my FreeBSD 12 workhorse panics on boot. I have updated /usr/src, then make buildworld make buildkernel KERNCONF=MYKERNEL make installkernel KERNCONF=MYKERNEL but after rebooting, kernel panic. Unfortunately, 'boot kernel.old' does not boot either. This system has a single zpool on a 3-way mirror. I have installed an additional hard drive and on that drive installed 12.2-STABLE. Fortunately, I have been able to import the old zpool 'zroot' of the 3-way mirror: # zpool status pool: buffrescue state: ONLINE scan: none requested config: NAME STATE READ WRITE CKSUM buffrescue ONLINE 0 0 0 ada3p3 ONLINE 0 0 0 errors: No known data errors 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: scrub repaired 0 in 0 days 00:36:07 with 0 errors on Wed Sep 18 12:25:53 2019 config: NAME STATE READ WRITE CKSUM zroot ONLINE 0 0 0 mirror-0 ONLINE 0 0 0 ada0p3 ONLINE 0 0 0 ada1p3 ONLINE 0 0 0 ada2p3 ONLINE 0 0 0 Also: # gpart status Name Status Components ada0p1 OK ada0 ada0p2 OK ada0 ada0p3 OK ada0 ada1p1 OK ada1 ada1p2 OK ada1 ada1p3 OK ada1 ada2p1 OK ada2 ada2p2 OK ada2 ada2p3 OK ada2 ada3p1 OK ada3 ada3p2 OK ada3 ada3p3 OK ada3 My question is: Is there any way to repair the kernel on the drives of the 3-way mirror? Please advise... -- Janos Dohanics
