This is usually a flash drive problem, try a different one if possible or redoing it manually, this can also help in some cases.
It will work but it will be very slow, even the GUI will likely lag, dual core with 4GB RAM is the minimum I would use for v6, also looks like you have a SASLP or SAS2LP, those are also not recommended for v6 due to multiple known issues, it should be replaced by an LSI HBA.
