Old System
Three servers.. Centos 7 -> Lay down VDO (dedup / compression) add those
VDO volumes as bricks to gluster.
New cluster (remove boot drives and run wipe of all data drives)
Goal: use first 512GB Drives to ignite the cluster and get things on feet
and stage infrastructure things. Then use one of the 1TB drives in each
server for my "production" volume. And second 1TB drive in each server as
staging. I want to be able to "learn" and not loose days / weeks of
data... so disk level rather give up capacity for sake of "oh.. well ..
that messed up.. rebuild.
After minimal install. Setup of network.. run HCI wizard.
It failed various times along build... lack SELInux permissive, .. did not
wipe 1TB drives with hope of importing old Gluster file system / VDO
voluemes to import my five or six custom and important VMs. (OCP cluster
bootstrap environment, Plex servers, DNS / DHCP / Proxy HA cluster nodes
et....)
Gave up on too many HCI failures about disk.. so wiped drives (will use
external NAS to repopulate important VMs back (or so is plan... see other
posting on no import of qcow2 images / xml :P )
Ran into next batch of issues about use of true device ID ... as name too
long... but /dev/sd? makes me nervious as I have seen many systems with
issues when they use this old and should be depricated means to address
disk ID: use UUID or raw ID...
"/dev/disk/by-id/ata-Samsung_SSD_850_PRO_512GB_S250NXAGA15787L
Started getting errors about HCI failing with "excluded by filter" errors.
wiped drives ( gdisk /dev/sd? => x => z => y => y)
filters errors I could not fiture out what they were.. .. error of "filter
exists" to me meant .. you have one.. remove it so I can remove drive.
Did full dd if=/dev/zero of=dev/sd? .. still same issue
filtered in multipath just for grins.... still same issue.
Posted to forums.. nobody had ideas
https://forums.centos.org/viewtopic.php?f=54&t=75687 Posted to slack
gluster channel.. they looked at it and could not figure out...
Wiped systems.. started over. This time the HCI wizard deployed.
My guess... is once I polished setup to make sure wizard did not attempt
before SELinux set to permissive (vs disable) drives all wiped (even
though they SHOULD just be ignored.. I I think VDO scanned and saw VDO
definition on drive so freeked some ansible wizard script out).
Now cluster is up.. but then went to add "production" gluster +VDO and
"staging" gluster + vdo volumes... and having issues.
Sorry for long back story but I think this will add color to issues.
My Thoughts as to root issues
1) HCI wizard has issues just using drives told, and ignoring other data
drives in system ... VDO as example I saw notes about failed attempt ...
but it should not have touched that volume... just used one it needed and
igored rest.
2) HCI wizard bug of ignoring user set /dev/sd? for each server again, was
another failure attempt where clean up may not have run. (noted this in
posting about manual edit .. and apply button :P to ingest)
3) HCI wizard bug of name I was using of device ID vs /sd? which is IMAO
... bad form.. but name too long.. again. another cleanup where things may
not have fully cleaned.. or I forgot to click clean ... where system was
left in non-pristine state
2) HCI wizard does NOT clean itself up properly if it fails ... or when I
ran clean up, maybe it did not complete and I closed wizard which then
created this orphaned state.
3) HCI Setup and post setup needs to add filtering
With a perfect and pristine process .. it ran. But only when all other
learning and requirements to get it just right were setup first. oVirt HCI
is Soooo very close to being a great platform , well thought out and
production class. Just needs some more nerds beating on it to find these
cracks, and get the GUI and setup polished.

This filter is correct for a normal oVirt host. But gluster wants to
use more local disks,
so you should:
1. remove the lvm filter
2. configure gluster
3. create the lvm filter
This will create a filter including all the mounted logical volumes
created by gluster.
Can you explain how do you reproduce this?
The lvm filter is created when you add a host to engine. Did you add the
host
to engine before configuring gluster? Or maybe you are trying to add a
host that
was used previously by oVirt?
In the last case, removing the filter before installing gluster will
fix the issue.
