Run setup again, when the problem shows again,
Crtl + Alt + F2 get in console,
Run this cmd,
/usr/sbin/vmkfstools -C vmfs3 -b 1m -S datastore9 /vmfs/devices/disks/naa.6000d7750000e13631b0b536d79c7024:1
after this done, run Ctrl + Alt + F6 back to setup screen ot just reboot run setup again, it shoud work
Give it a try?
