Upgrade to 2.1.2: Stuck on 2.1

fdisk -a /dev/ad0

I get an Intput/Output error.

This is compact flash card. It was installed as 2.0 and then upgraded to 2.0.3 and later 2.1.

In my case I had pfSense nanobsd v1.2.3 upgraded to v2.0, that one upgraded to v2.1 - all of them upgraded OK. Now when I wanted to upgrade to v2.1.2, It seems corrupted. I'm preparing a fresly flashed CF card with config already put in.

me too

I am having the same issue. Hopefully my situation will help shed some light.

I have upgraded at least two other NanoBSD 4G (ALIX) system without issue.
Today I am upgrading three identical boxes - ALIX boards running 4G CF card
One existing install was already 2.1 and I successfully upgraded to 2.1.2
The other two were at 2.0.3 and I successfully upgraded to 2.1, but they are both now stuck on 2.1 after auto-upgrade and manual upgrade attempts.

robi

Also a side note, I'm not on Alix, but on a Jetway JNF99 with 5 intel nics, Atom CPU and 4GB of RAM, i386 build. The new CF card will carry a 64-bit version this time.

jimp

If you're getting an "i/o error" or "device not configured", reboot and try again. At least for the "i/o error" it seems to lean more toward maybe a bad CF but it's still tough to say for sure.

Also worth a try:

sysctl kern.geom.debugflags=16
fdisk -B -b /boot/boot0 ad0

I'm in the same boat with 40 plus devices scattered across 4 provinces. I actually haven't managed to get a single one to upgrade except the 3 in our local offices that I performed a clean install on, 2G and 4G, current versions 2.03 and 2.1 on all remotes attempting auto upgrade and manual firmware uploads. Not sure what to do, since I don't want to risk chopping them up and losing remote connectivity. I don't own a helicopter to get around that quickly ;D

All Alix boards. Errors in the upgrade log

I have same issue apparently. No answer. Here's my log:

@mjohnson:

I'm in the same boat with 40 plus devices scattered across 4 provinces. I actually haven't managed to get a single one to upgrade except the 3 in our local offices that I performed a clean install on, 2G and 4G, current versions 2.03 and 2.1 on all remotes attempting auto upgrade and manual firmware uploads. Not sure what to do, since I don't want to risk chopping them up and losing remote connectivity. I don't own a helicopter to get around that quickly ;D

All Alix boards. Errors in the upgrade log

fdisk: invalid fdisk partition table found
bsdlabel: /dev/ad0s3: no valid label found
bsdlabel: /dev/ad0s3: no valid label found
bsdlabel: /dev/ad0s3: no valid label found
tar: Failed to set default locale
tar: Failed to set default locale
shutdown: [pid 24752]

I hear ya about all those remote devices and no time to travel there if there is a problem. For me if there is a risk of breaking it at a remote site I would send them another firewall box and tell them to swap it when time permits. This way the new firewall is working at the corporate office with the remote site's configuration file and should work fine when it reaches at the remote site. Then have them send the old one back to redo for another site.

I know it's a PITA. Might be good for critical sites that can't go down for any period of time. Hopefully soon we can get these upgrade issues sorted out.

I have a faulty image in my hands now, hopefully I can track down a solution soon.

Current theory is that it was actually corrupt before the latest update and it just started to show it now, but once I have more time to experiment with the broken CF image I'll know for sure.

I'm certain we can come up with a fix, but it might be something scary like doing a DD of a good partition table to the start of the disk. Not something I'd generally recommend however in theory all NanoBSD images of the same size should have the same partition layout so it may be safe.

In the meantime I'd like to find out if everyone involved here had 4GB NanoBSD images, or both 2GB and 4GB, or even more.

me too

Both 4GB CF for me.

2 and 4GB for me.

Jim,

I have both 2G and 4G nanobsd images displaying this problem.

For those of you that have an issue, show me the output of:

fdisk -p /dev/ad0

And note if it's 2gb or 4gb.

If you have a working system of the same size to compare against, show the output from it also.

Those last two are interesting in that they're nearly identical and one works and the other doesn't. I expect some variation as we have, over time, slightly shrunk the NanoBSD slice sizes, but that is a bit curious.

The .img file I read from the CF with the "corrupt" table appears to be OK, despite the CF showing a damaged table. So I'm left to wonder if there may be some other CF-related factor at play.

The following commands could be dangerous so if you choose to attempt them, proceed with extreme caution. I tested these on my own ALIX with a good MBR and it survived, but there are no guarantees. You need only try one of these methods unless it doesn't help, then proceed to the next one.

Method #1: Rewrite the MBR+Partition table with dd

sysctl kern.geom.debugflags=16
dd if=/dev/ad0 of=/tmp/mbr_part_bkup.img bs=512 count=1
dd of=/dev/ad0 if=/tmp/mbr_part_bkup.img bs=512 count=1

Method #2: Have fdisk reset the partition table:

sysctl kern.geom.debugflags=16
fdisk -p /dev/ad0 > /tmp/fdisk_bkup.txt
fdisk -if /tmp/fdisk_bkup.txt /dev/ad0

Method #3: Take a "working" fdisk output and rewrite using it. I can't stress enough that you must make sure the partition boundaries line up, don't grab the fdisk output from a differently sized card:


# Get the "fdisk -p" output from a similar but working CF, save it in /tmp/fdisk_bkup.txt
sysctl kern.geom.debugflags=16
fdisk -if /tmp/fdisk_bkup.txt /dev/ad0

After any of those, chances are that no commands will work to reboot the unit, so either pull the power or run the following to force a panic+reboot:

sysctl debug.debugger_on_panic=0
sysctl debug.kdb.panic=1

After that has completed, try the upgrade once again.

Obviously that isn't something you'd want to try on a remote unit.

mkomar

All of mine are in remote locations and in production. Can't risk taking them down.

I'll be swapping them out with upgraded (Software) replacements in the next week or so.

Is there value in trying these fixes after that?

It would still help to know if any of the above methods would correct the faulty partition table, so that others can benefit from the knowledge.

mkomar

I should have a couple of those units on hand next week. I'll give it a shot and report back once I've done so.

mkomar

JimP - Should have my hands on one or two of the malfunctioning units in the next few days. I'd be happy to try the various fixes you have proposed, and/or if it would be of more value, I'd be happy to either get you serial access to one or both of them and/or get either CF card(s) and/or dd img dumps out to you.

Would any of the options work better than others as far as getting a 'known good' fix out there?
