  2. Thanks bro, i passed my RHCE, you were right the test is not hard at all. now i can go on with RHCA. jaja thanks again.

  3. Hi guys,
    I have a question:
    I took the RHCE exam a couple of days a go and failed with ZERO points. How? Because after running lsblk and fdisk -l I was not seeing any free space other then VDA1/VDA2 on the test.I tried to create a new extended partition under the root partition (i KNOW STUPID) for ISCSI target and the system would not boot. Funny thing though, had I left this question alone and accept the loss of points I know I would have passed as the other questions were straight forward. I expect I should have had an additional partition such as VDB/VDC to partition.
    I still don’t know how and why I could not find any LV or other partition for that !!! I am so sad, disappointed … but, I have hope to future. I have plan to retake the exam soon. So, please let me know where was my problem.
    BTW, I am aware of non-disclosure agreement. And I respect to that. I just ask a friendly help to figure out where was my weakness.

    Thanks,
