it works well. I have create the lvm partitions like the onode01 and I have added the
bricks from onode02 and onode03.
after that t have add the hosts into ovirt and and it works well to.
but to add the nodes I have to remove the ovirt yum repos from /etc/yum.repo.d because
then he will not try to download a newer version.
but I have now only one open point. the volumes with three bricks are there but only the
hosted engine domain is there. the iso and vmstore domain was not there. strange. I think
it was available on the single note but I try to reinstall all three servers again to be
sure that it's works.

I guess the gluster documentation at https://docs.gluster.org/
If you have a single brick volume of type Distributed, then you can add
2 more bricks and convert the volume to 'replica 3' or 'replica 3
gluster volume add-brick help
gluster volume add-brick <VOLUME-even-Hosted-Engines> replica 3
[arbiter 1] ovirt2:/path/to-brick ovirt3:/path/to-brick
If you remove the square brackets so the type is 'replica 3 arbiter 1'
the second brick will be treated as an arbiter.
WARNING: You need to create your bricks with inode size of at least 512
'mkfs.xfs -i size=512 /dev/vg/lv'. If you wish to use the snapshot
functionality (I use it to snapshot my Engine's volume before
patching), all bricks in the volume must use thin LV (which I think is
not the default by the ansible plays).
Ovirt was quite sensitive with the block device's physical sector size
(lsblk -t shows it as PHY-SEC). If yours is bigger than 512 , you might
(I'm not sure about new version of oVirt) need to use VDO with
Note: For an arbiter brick with XFS file system , it's worth
considering to use an SSD and setting a higher percentage of inodes
(option 'maxpct=' of mkfs.xfs).

where can I find some documents for the conversion to replica? works
this also for the engine brick?

> Hello Gobinda,I know that gluster can easily convert distributed
volume to replica volume, so why it is not possible to first convert to
replica and then add the nodes as HCI ?Best Regards,Strahil NikolovВ
