[Bug 1962061] Re: ZFS Key load error: Failed to open key material file: No such file or directory

[geole0]

The little script that makes ZFS booting impossible.
sudo -i

#1) Montage des partitions contenant le logiciel
rmdir /ZFS
zpool import  -N -R /ZFS rpool && sleep 5 
zfs set canmount=on  rpool && zfs mount -v rpool
for var in $(zfs list | grep ROOT/ubuntu|cut -d" " -f1)
do
     echo $var
     zfs set canmount=on $var && zfs mount -v $var 
     sleep 1
done
  
#2) On récupère la séquence de boot. Mais c'est celle obtenue en mode recovery et pas la dernière !!!
journalctl -b -p err -D /ZFS/var/log/journal >/home/a/boot-ERR.txt
journalctl -b        -D /ZFS/var/log/journal >/home/a/boot-TOT.txt

#3) On démonte le root
for var in $(zfs list | tac | grep ROOT/ubuntu|cut -d" " -f1)
do
     echo $var
     zfs unmount  $var &&  zfs set canmount=off $var &&  sleep 1
done
zfs unmount  rpool && zfs set canmount=off  rpool && sleep 1
umount -v --recursive /ZFS
zpool export rpool
zpool list

Title:
  ZFS Key load error: Failed to open key material file: No such file or
  directory

Status in systemd package in Ubuntu:
  New

Bug description:
  Hello
  The message is

  Key load error: Failed to open key material file: No such file or
  directory

  Command: mount -o zfsutil -t zfs rpool/ROOT/ubuntu_ui69ph /root// Message: filesystem 'rpool/ROOT/ubuntu_ui69ph' can not be mounted: Permission denied
  filesystem 'rpool/ROOT/ubuntu_ui69ph' can not be mounted: Permission denied


  
  Hello
  I recently installed an encrypted ZFS 22.04 version.
  She boots well.
  I can do the updates and reboot except that now the reboot is impossible because of the message above.
  I suspect that access to the encryption keys has become impossible.

  The reason could be a borrowing of these keys by another O.S. with poor quality playback. For example forget to free the key file
  because the incident is systematic

  
  have a good day
