Hi There,
Am a newbee to vertica and following is my setup.

• Win 7 i7 laptop
• 5.1 virtualbox + bridged n/w.
• rhel 7.3 vm is able to connect to internet
• installed vertica CE edition and got multiple errors. fixed all of them except 3. one is ext4 fs error, for which i will create a new VM ( currently its xfs ) and try to fix that later , same with LVM.
• running in to IO - S1051 error, have tried with noop and deadline both with elevator and cmd line, however no luck.

Thank you sarafunes. Yes, i re-created a new Vm with stadard partition with ext4 and set elevator to deadline.
