4:56 p.m.
Greetings:
3 x servers each server has 1 x 512GB ssd 2 x 1TB SSD JBOD
Goal: use HCI disk setup wizard to deploy initial structure
Each server has disk scanning in as different /dev/sd# and so trying to
use more clear /dev/mapper/<disk ID>
As such I set this per table below:
# Select each server and set each drive <<<<<<<<<<Double
Check drive
device ID as they do NOT match up per host
# I transitioned to /dev/mapper object to avoid unclearness of /dev/sd#
thor
/dev/sdc
/dev/mapper/Samsung_SSD_850_PRO_512GB_S250NXAGA15787L
odin
/dev/sdb
/dev/mapper/Micron_1100_MTFDDAV512TBN_17401F699137
medusa
/dev/sdb
/dev/mapper/SAMSUNG_SSD_PM851_mSATA_512GB_S1EWNYAF609306
# Note that drives need to be completely clear of any partition or file
system
[root@thor /]# gdisk /dev/sdc
GPT fdisk (gdisk) version 1.0.3
Partition table scan:
MBR: protective
BSD: not present
APM: not present
GPT: present
Found valid GPT with protective MBR; using GPT.
Command (? for help): x
Expert command (? for help): z
About to wipe out GPT on /dev/sdc. Proceed? (Y/N): y
GPT data structures destroyed! You may now partition the disk using fdisk or
other utilities.
Blank out MBR? (Y/N): y

But deployment fails with Error:

Why is oVirt ignoring when I set (and double check explicite device call
for deployment?
Attached is the ansible file it creates and then one I had to edit to
correct what wizard should have built it as.
