This can happen if slice0 is size 0. KISS would say to do:
zpool create marketData raidz2 \
c0t5000C5001A6B9C5Ed0 \
c0t5000C5001A81E100d0 \
c0t5000C500268C0576d0 \
c0t5000C500268C5414d0 \
c0t5000C500268CFA6Bd0
c0t5000C500268D0821d0
This method will create slice0 (s0) as the full disk, on your behalf.
