comment Software RAID 10 not any faster than s/w RAID 5 on Ubuntu 14.04 box, why?
@DavidSchwartz For RAID 10 you still only need to work with two disks, while for RAID 5 you need to work on all disks.

I would expect random writes in RAID 5 to be considerably slower. For RAID 10 you have to write to two disks only. For RAID 5, you have to write the block to one disk, write out the parity to another, but additionally you also have to read out the rest of the data blocks from the same stripe in order to recalculate that parity.

comment Fail2Ban - Iptables - Set does not exist
As you can see, your running kernel (2.6.32-042stab092.2) is not a CentOS 7 kernel. It seems that you are inside a virtualized OpenVZ container. You may want to bring this up with your hosting provider, or also check this for extra information: unix.stackexchange.com/questions/118263/…
