upgrade 2.6.0 to 2.7.0 not booting: UFS cannot be mounted anymore (superblock CGSIZE)
-
On FreeBSD Bugzilla someonce commented that the available patch apparently is not yet in pfsense 2.7.0
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=264450But, looking, 14.0-CURRENT@0c59e0b4e581 is from 2023-Mar-30, long predating the fix reported in comment #15 . The issue is a known problem with the old release involved, one that has been fixed. My guess here is that pfsense needs to be based on an updated FreeBSD that has the fix reported in #15 . Time for a 2.7.1 ? -

I think you're out by a year.
That fix was commited in May 2022. It's in pfSense 2.7. Along with numerous more recent fixes.

My mistake this commit: https://github.com/pfsense/FreeBSD-src/commit/800a53b445e7eb113ba193b1ac98631299178529
In June 2022 as shown in the bug.

@dneuhaeuser I encountered this same issue - it's definitely a kernel bug, if I boot the old kernel it can read the FS but there are significant issues that causes it to not be safe (like copy doesn't work). I suspect that if you were to copy a 2.7.2 kernel off and boot that on the 2.7.0 system it would work properly. I went through and upgraded from 2.7.0 to 2.7.2 and it could read everything fine once again. It seems to be some error in how the 2.7.0 UFS is calculating cgsize. After I upgraded by booting the old kernel, lots of files were zero sized because of the failure to copy files (for example all the nginx config files were empty)
I ended up just reinstalling from a 2.7.2 DVD, but I'll probably try the 2.7.2 kernel on 2.7.0 route on the next one I try this on.

You were also upgrading from 2.6 to 2.7 when you hit it?
-
@stephenw10 yes that is correct - I posted a lot of details in slack but the important bits are above.
-
@stephenw10 FYI I had to upgrade another system and the same thing happened. I booted the 2.7.2 install cd and mounted the old root. Copied /boot/kernel to /mnt/boot/kernel.new then booted that. Everything worked fine. Would be nice if the installer could have the kernel updated to one that's not bugged
-
The 2.7.2 installer? It seems like that is good if you're able to mount the old root from it no?
-
@stephenw10 sorry my message was unclear, I meant the kernel in the upgrade that the UI applies. Yes the 2.7.2 installer is good… but you have to go to 2.7.0 first because…. Reasons?
-
Oh, I see so if you have this specific UFS install the 2.7.0 kernel will not boot from it. The 2.7.2 kernel will boot from it but you have to go through 2.7.0 because that was the first version that added dynamic repos. Hmm. Yeah I'm not sure what we can do about that at this point. You can always install 2.7.2 clean and restore the config from 2.6.
