aufs and tmpfs at 100% Use. No Space Error!

[Chris Young]

I'm trying to finish up a USB flash drive that will allow me to backup and restore. I'm running into some problems with the backup portion.

A portion of my syslinux.cfc file:

label BACKUP
  #MENU DEFAULT
  # MENU HIDE
  MENU LABEL Back up files and settings
  # MENU PASSWD
  #mkdir -p /dev/sdb1/home/partimag/  <--- I have tried it with this line and the next line uncommented.
  #mount /dev/sdb1 /home/partimag/              The results are the same.
  kernel /live/vmlinuz1
  append initrd=/live/initrd1.img boot=live union=aufs    nolocales noprompt ocs_live_run="/opt/drbl/sbin/ocs-sr -q2 -j2 -rm-win-swap-hib -z1 -i 2000000 -p poweroff savedisk "image" "sda"" ocs_live_extra_param="" ocs_live_keymap="NONE" ocs_live_batch="yes" ocs_lang="en_US.UTF-8" vga=788 ip=frommedia

I get an error that /home/partimag is full! No space left on device!

df -a shows me:

aufs mounted on / and tmpfs mounted on /live/cow are both at 100% usage.

Any suggestions on getting this up and working? I'm using an older version of clonezilla (clonezilla-live 1.2.2-31) due to some hardware problems for a particular system I'm working with. Everyone thing works perfectly fine if I manually backup/restore.

I have since changed 2000000 to 2000 but forgot to paste the latest config info.

"mkdir -p /dev/sdb1/home/partimag" can not be put in the syslinux config as the command. You have to use "ocs_prerun" boot parameter to make that:

e.g.
append initrd=/live/initrd1.img boot=live union=aufs nolocales noprompt ocs_live_run="/opt/drbl/sbin/ocs-sr -q2 -j2 -rm-win-swap-hib -z1 -i 2000000 -p poweroff savedisk image sda" ocs_live_extra_param="" ocs_live_keymap="NONE" ocs_live_batch="yes" ocs_lang="en_US.UTF-8" vga=788 ip=frommedia ocs_prerun="mount /dev/sdb1 /home/partimag"
