You can edit per host in the cockpit UI if you have non-uniform hosts. If you still run into issues, please paste the generated gdeploy config file to check On Wed, Feb 13, 2019 at 8:54 PM Edward Berger <edwberger@gmail.com> wrote:

I don't believe the wizard followed your wishes if it comes up with 1005gb for the thinpool. 500gb data + 500gb vmstore +5gb metadata = 1005gb

The wizard tries to do the same setup on all three gluster hosts. So if you change anything, you have to "check and edit" the config file it generates in all three locations before deploy..

With only 450gb min-size-disk, I'd start over again, delete the data and vmstore domains during the wizard setup and bump up engine size to fill up the available space on the smallest disk (400gb or so).

The other domains aren't necessary and you might want to give them their own larger disks later.

Hi,

I am currently setting up an Ovirt cluster in a test environment and cannot get the hyperconverged setup to run properly. I have installed 3 nodes on version 4.2.8.

I keep getting the following error -

TASK [Create LVs with specified size for the VGs] ****************************** failed: [node01.ovirt.local] (item={u'lv': u'gluster_thinpool_sdb', u'size': u'1005GB', u'extent': u'100%FREE', u'vg': u'gluster_vg_sdb'}) => {"changed": false, "item": {"extent": "100%FREE", "lv": "gluster_thinpool_sdb", "size": "1005GB", "vg": "gluster_vg_sdb"}, "msg": " WARNING: Pool zeroing and 3.00 MiB large chunk size slows down thin provisioning.\n WARNING: Consider disabling zeroing (-Zn) or using smaller chunk size (<512.00 KiB).\n Volume group \"gluster_vg_sdb\" has insufficient free space (157261 extents): 343040 required.\n", "rc": 5} to retry, use: --limit @/tmp/tmpbXqHhw/lvcreate.retry

All 3 nodes have an /sdb installed which are different sizes but all in excess of 450Gb. I have specified JBOD in the setup.

I have tried reducing the size of the engine, data and vmstore bricks to 50Gb each instead of the default but the installation still fails.

I think it has something to do with the thin provisioning but not sure what.

Any help would be much appreciated.

Thanks Paul. _______________________________________________ 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/BXNOIJCQHCOZCH...
