Symptoms
cpcfg fails with errors similar to:
Getting configuration from HD1.2
info: Copying configuration to HD1.1
info: Applying configuration to HD1.1
info: >++++ result:
info: Extracting manifest: /var/local/ucs/config.ucs
info: /: Not enough free space info: 739487744 bytes required
info: 259965952 bytes available
info: /var/local/ucs/config.ucs: Not enough free disk space to install!
info: Operation aborted.
Impact
You cannot use cpcfg to copy a UCS file to a volume set with a root filesystem that has less free space than the total UCS size
Conditions
Use cpcfg for a UCS that is larger than free space on root filesystem of target volume set.
Workaround
Run the below to fix /etc/mtab on target (HD1.3 is used in this example; substitute the correct target volume) before cpcfg:
- volumeset -f mount HD1.3
- grep HD1.3 /proc/mounts | sed 's_/mnt/HD1.3_/_g;s_//_/_g' > /mnt/HD1.3/etc/mtab
- volumeset -f umount HD1.3
Fix Information
cpcfg could incorrectly calculate the amount of free space required, refusing to do the copy unless the / filesystem on the target volume had sufficient space to do the copy (not taking into account /config, /usr, /var, and other filesystems). This has been resolved and this free space calculation is done correctly.
