You may try:

Increase the size of the filesystem holding SPOT directory by say 50 GB , try spot creation again
Else, see if the mksysb image is corrupted by running this command : restore -Tqvf <mksysbfilename>

Incase someone faces such issue.
Make sure you use the mksysb object name while creating spot, Not the Path of the mksysb. (in the install image field while creating Spot)
