Hi Femi/Sandro, - In Step #2: Fqdns: for a 3 host cluster, are we to add the 2nd & 3rd hosts? Yes, Earlier the addition of 2nd and 3rd hosts was manual,Now we have included along with deployment. - In Step #5: Bricks: What effect does the RAID setting have? So basically If gluster drops in quorum then it will stop file operations until quorum is back to normal. So you need two bricks to write for quorum to be met.To overcome the issue will have raid. Enable Dedupe & Compression is new? Yes it's a new feature and it's optional. Configure LV Cache: what do we enter for SSD? What happens if my disks are already all SSD, do I still benefit from using this? I don't think you need to use LVM Cache if you are already using SSDs or LVMe. LVM Cache is meant for to improve performance over HDDs by combining with SSD as cache device. On Mon, Jul 23, 2018 at 12:41 PM, Sandro Bonazzola <sbonazzo@redhat.com> wrote:

Hi Femi, Yes, the configuration should be based on Hardware you are using. To clarify further about your RAID question: Main usage of RAID in cockpit is to set the alignment values when creating the lvm and filesystem. The settings provided should reflect the hardware RAID configuration on the system, if the disks have been setup with RAID.

Gobinda, thx for the info.

In "Raid Type, Strip size & disk count", should that info supplied be based on the hardware I'm using for the install?

for example, Data Disk Count - do I enter the quantity of disks I have on 1 host? _______________________________________________ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-leave@ovirt.org Privacy Statement: https://www.ovirt.org/site/privacy-policy/ oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/JKUO7C2J4MDKYM...

Hi Femi, So theoretically it should work.Certain things need to be taken care like you need to provide correct MDADM configuration and in "Device" you need to give the correct path. We are not recommending MDADM because of performance issue and it will eat more CPUs. We have not tested with MDADM, but theoretically it should work. Let me know if any issue.I will try to help.

Hi Gobinda,

Thanks for more detail.

What if I use MDADM (instead of hardware RAID), do the settings change? _______________________________________________ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-leave@ovirt.org Privacy Statement: https://www.ovirt.org/site/privacy-policy/ oVirt Code of Conduct: https://www.ovirt.org/community/about/community- guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/ message/75OANWKGOVDZTEFW6JO7KP4WK5C55HFL/

Hi Gobinda, When you say "not recommending MDADM", does that apply to just this version 4.3 of oVirt or all versions of oVirt?
