Blue config recovery.. crashes on boot

I have a crashed Blue that keeps rebooting after 30 seconds on startup. It just acquires an IP address but then dies. I would like to recover the HA configuration if possible. Stupidly it’s stored on the Blue only.

So I can flick the switch inside Blue and boot into petitboot and I can see the volumes. Is there a way to copy the HA configuration off of the Blue so I can wipe the EMMC with a fresh install and then reload the old configuration? Mounting one of the volumes on a PC by USB perhaps? Or maybe I can repair the EMMC so it boots and retain the configuration backups ?

If it is useful this is displayed about 10 secs before it reboots.

FAT-fs (mmcblk0p1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck.

I have lots of these volumes suffixed …p0 to p9. Are these each Docker related ? As the OS doesn’t stay up long enough I’m fairly stuck re what I can do. Only petitboot stays up.

I am also wondering if the storage could have filled up ? Is so how to free some space.

Did you solve this? I think the same thing has happened to me. it keeps rebooting.

I did a totally new install
