Hi Kristof, it's great to read You! =20 On Mon, Dec 07, 2020 at 09:11:32PM +0100, Kristof Provost wrote: !

No offense meant, but this is not really a good time for that. This is the most horrible upgrade I experienced in 25 years FreeBSD (and it was prepared, 12.2 did run fine on the other machine). I have issue with mem config https://forums.freebsd.org/threads/fun-with-upgrading-sysctl-unknown-oid-vm= -pageout_wakeup_thresh.77955/ I have issue with damaged filesystem, for no apparent reason https://forums.freebsd.org/threads/no-longer-fun-with-upgrading-file-offlin= e.77959/ Then I have this issue here which is now gladly workarounded https://forums.freebsd.org/threads/panic-12-2-does-not-work-with-jails.7796= 2/post-486365 and when I then dare to have a look at my applications, they look like sheer horror, segfaults all over, and I don't even know where to begin with these. Other option: can you make this fix so that I can patch it into 12.2 source and just redeploy? I tried to apply the changes from r368237 into my 12.2 source, that seemed to be quite obvious, but it doesn't work; jails fail to remove entirely: # service jail stop rail Stopping jails: rail. # jexec rail jexec: jail "rail" not found -> it works once. # service jail start rail Starting jails: rail. # service jail stop rail Stopping jails: rail. # jexec rail root@rail:/ # ps ax ps: empty file: Invalid argument -> And here it doesn't work anymore, and leaves a skull of a jail one cannot get rid of. Cheerio, PMc
