cdo ensmean (Abort): Inconsistent ensemble file, too few time steps

I have 7 files, 5 of them have 240 time steps while the other 2 only have 238 time steps. that's why when I used:
cdo ensmean ifile[1-7] ofile

it said;
cdo ensmean (Abort): Inconsistent ensemble file, too few time steps in ifile1

what should I do to make the time steps 240 for the 2 files?

Thank you!!

I am also having this error. Can anyone post a solution here
Much appreciated.
