Recover config file from ISO during (re)install?
-
There was a recent PR to read a recovery config off ISO, it should be possible in Plus 24.03 / CE 2.8.0:
-
Oh I see. Yeah that would be helpful for VMs. Fun!
-
@stephenw10 I want to add to this; I just tried with a FAT32 formatted harddisk file (VHDX) connected to a new VM, but the pfSense installer found nothing. When I manually mount the disk from the recovery shell, and copy the config.xml to /tmp/recovered_config it works. It seems the harddisk isn't mounted automatically.
Anyway, until recovery from ISO works, this would still be faster for us than first install CE, configure VLAN and networking and then recover config using ssh /scp or webgui. Let's hope 2.8 will indeed include this! When disaster hit, being able to quicly recover spares some sweat for other things.Thanks all!

How did that additional disk appear in pfSense? Like adaX?
I expect it to check anything that appears under
sysctl kern.disks:
https://github.com/pfsense/pfsense/blob/master/src/etc/rc.ecl#L57 -
@stephenw10 It appears as da1. (da0 being the disk I'd want to install to). It seems to have two partitions, da1p1 and da1p2, even though I just made a single FAT32 partition on it. Obviously when I run dmesg, the 4GB disk I created with the config file on shows up, but I'm too limited in terms of regular linux commands that are missing is this minimal recovery shell, so I can't see too much. If you need any specific output, just tell me.

You should see the list of devices it checks during boot as the external config locator runs. That should be the same list it tries to recover from at install.
Be careful because if/when this does work it will pull in that config at every boot until you detach the disk!
Otherwise I would try to mount the drive from the recovery prompt and check it:
mount_msdosfs /dev/da1p1 /mnt ls -ls /mnt -
@stephenw10 Yeah that's what I already did manually. However, even after mounting I manually have to copy the config file to /tmp/recovered_config/config.xml for it to work, and then everything works fine. But if after mounting, I exit to the install-menu, and choose recovery config, it still doesn't find it. Doesn't matter if it's in / or /conf of that disk.
-
So what does
ls -ls /mntactually show?What does the ECL show it's checking at first boot if the drive is still attached?
-
If I don't manually mount anything, ie. after a reboot with an empty disk attached as SCSI:0:0, a 4GB disk attached to SCSI:0:1 formatted as FAT32 with the config in it, and a DVD drive with the ISO, /mnt is completely empty. Output of ls -ls /mnt: total 0
Not sure what you mean by your other question?
-
I meant how does that appear after you mount it? And which partition did you mount?
During a normal boot the External Config Locator attempts to pull in a config from an attached drive and it shows the drives it's looking at:
External config loader 1.0 is now starting... da0s1 da0s2 da0s2a da0s3 nda0p1 nda0p2 nda0p4Does it show the attached drive in your VM?
-
I can't properly copy / paste as booting from ISO doesn't give me network, and I don't have serial on Hyper-V. So I'll try like this:
During boot I don't see the ECL logging anything at all, even with verbose enabled. Or it's too quick for me to see. What log file would that be in? I attached /var/log/messages, but after recognizing the disks, I don't see it referenced again. Note that I actually ran the config-recovery option before taking the log file. My apologies if I'm misunderstanding.
-
Ok great. And in the conf directory you have config.xml?
The ECL runs during a normal boot of the installed pfSense not booting the installer. But it looks in the same places as the config recovery that runs in the installer so if it appears there I'd expect it to also recover from there.

yes, config.xml is in /conf.
-
Ok alternative approach!
Drop to the rescue shell from the installer then run the config recovery manually from there like:
/root/recover_configxml.shThat will then show exactly what it's doing and you'll be able to see it.
-
That simply shows:
No suitable disk partitions found
whether I mounted the partition or not.
-
Hmm, Ok I guess that only looks for existing installs. Let me see....
-
Yup. OK try:
/usr/libexec/bsdinstall/copy_configxml_from_usbIt should check anything that shows up as fat32 in
gpart show -pso that should include da1p2. -
It shows as ms-basic-data, I'm not sure what it should say. But it's formatted as FAT32 in Windows, and BSD can surely read it.
-
Ok that's some windows formatting problem then. It's not marking it as fat32. It should show like:

That's a Windows partitioning issue and unfortunately it's not safe to assume anything based on it. Partitions with that type could be NTFS, ExFAT, FAT32, whatever, so we can't just add code to allow that type alongside the current code.
https://en.wikipedia.org/wiki/Microsoft_basic_data_partition
You'll need to find a way to change that partition type. Some googling suggests it can be done but it's not exactly trivial.
