PiZero fails to boot after upgrade

[Bruce Rindahl]

Using ClusterHAT-2017-11-29-lite-2-usbboot.zip to boot two zeros over usb. Followed directions,worked perfectly. Later I did sudo apt-get update & upgrade on the controller with no issues. But when I do update & upgrade from the zeros they do not boot. LED flashes but does not stay on or boot. I have done this twice to confirm. Individual zeros work until upgrade.
Ideas?

Hi,

Using ClusterHAT-2017-11-29-lite-2-usbboot.zip to boot two zeros over usb.  Followed directions,worked perfectly.  Later I did sudo apt-get update & upgrade on the controller with no issues.

One of the upgrades is for the kernel so it'll need the initramfs rebuilding otherwise it won't have the kernel modules it needs to continue booting.

On the controller (with power off to the Pi Zeros).

for I in 1 2 3 4 ; do

 for V in `(cd /var/lib/clusterhat/nfs/p$I/lib/modules/;ls|grep -v v7)`; do

  chroot /var/lib/clusterhat/nfs/p$I/ /bin/bash -c "mkinitramfs -o /boot/initramfs.img $V"

 done

done

You should then be able to start them up as normal.

That did the trick.
Thanks!

Hi Chris,

I have the same problem... I try to run the code that you provided in a bash file and show this error :

./commd.sh: line 3: cd: /var/lib/clusterhat/nfs/p1/lib/modules/: No such file or directory

chroot: failed to run command ‘/bin/bash’: No such file or directory

Hi, 

./commd.sh: line 3: cd: /var/lib/clusterhat/nfs/p1/lib/modules/: No such file or directory

chroot: failed to run command ‘/bin/bash’: No such file or directory

If the directory doesn't exist you're not running the usbboot image so this wouldn't apply.

I would advise starting your own thread explaining how you have everything setup and what the problem is.

Chris.
