oVirt - Gluster Node Offline but Bricks Active
by Jeremey Wise 24 Sep '20

oVirt engine shows one of the gluster servers having an issue. I did a graceful shutdown of all three nodes over weekend as I have to move around some power connections in prep for UPS. Came back up.. but.... [image: image.png] And this is reflected in 2 bricks online (should be three for each volume) [image: image.png] Command line shows gluster should be happy.

Gluster Name too long
by Jeremey Wise 24 Sep '20

24 Sep '20

Deployment on three node cluster using oVirt HCI wizard. I think this is a bug where it needs to do either a pre-flight name length validation, or increase valid field length. I avoid using /dev/sd# as those can change. And the wizard allows for this change to a more explicit devices Ex: /dev/mapper/Samsung_SSD_850_PRO_512GB_S250NXAGA15787L Error: TASK [gluster.infra/roles/backend_setup : Create a LV thinpool for similar device types] *** task path: /etc/ansible/roles/gluster.infra/roles/backend_setup/tasks/thin_pool_create.yml:239 failed: [thorst.penguinpages.local] (item={'vgname': 'gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L', 'thinpoolname': 'gluster_thinpool_gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L', 'poolmetadatasize': '3G'}) => {"ansible_loop_var": "item", "changed": false, "err": " Full LV name \"gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L/gluster_thinpool_gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L_tdata\" is too long.\n Full LV name \"gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L/gluster_thinpool_gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L_tdata\" is too long.\n Full LV name \"gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L/gluster_thinpool_gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L_tdata\" is too long.\n Full LV name \"gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L/gluster_thinpool_gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L_tdata\" is too long.\n Full LV name \"gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L/gluster_thinpool_gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L_tdata\" is too long.\n Full LV name \"gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L/gluster_thinpool_gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L_tmeta\" is too long.\n Internal error: LV name \"gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L/gluster_thinpool_gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L_tmeta\" length 130 is not supported.\n Internal error: LV name \"gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L/gluster_thinpool_gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L_tdata\" length 130 is not supported.\n Internal error: LV name \"gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L/gluster_thinpool_gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L_tmeta\" length 130 is not supported.\n Internal error: LV name \"gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L/gluster_thinpool_gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L_tdata\" length 130 is not supported.\n", "item": {"poolmetadatasize": "3G", "thinpoolname": "gluster_thinpool_gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L", "vgname": "gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L"}, "msg": "Creating logical volume 'None' failed", "rc": 5} failed: [medusast.penguinpages.local] (item={'vgname': 'gluster_vg_SAMSUNG_SSD_PM851_mSATA_512GB_S1EWNYAF609306', 'thinpoolname': 'gluster_thinpool_gluster_vg_SAMSUNG_SSD_PM851_mSATA_512GB_S1EWNYAF609306', 'poolmetadatasize': '3G'}) => {"ansible_loop_var": "item", "changed": false, "err": " Internal error: LV name \"gluster_vg_SAMSUNG_SSD_PM851_mSATA_512GB_S1EWNYAF609306/gluster_thinpool_gluster_vg_SAMSUNG_SSD_PM851_mSATA_512GB_S1EWNYAF609306\" length 130 is not supported.\n", "item": {"poolmetadatasize": "3G", "thinpoolname": "gluster_thinpool_gluster_vg_SAMSUNG_SSD_PM851_mSATA_512GB_S1EWNYAF609306", "vgname": "gluster_vg_SAMSUNG_SSD_PM851_mSATA_512GB_S1EWNYAF609306"}, "msg": "Creating logical volume 'None' failed", "rc": 5} changed: [odinst.penguinpages.local] => (item={'vgname': 'gluster_vg_Micron_1100_MTFDDAV512TBN_17401F699137', 'thinpoolname': 'gluster_thinpool_gluster_vg_Micron_1100_MTFDDAV512TBN_17401F699137', 'poolmetadatasize': '3G'}) => {"ansible_loop_var": "item", "changed": true, "item": {"poolmetadatasize": "3G", "thinpoolname": "gluster_thinpool_gluster_vg_Micron_1100_MTFDDAV512TBN_17401F699137", "vgname": "gluster_vg_Micron_1100_MTFDDAV512TBN_17401F699137"}, "msg": ""} I will revert back to /dev/sd# for now... but this should be cleaned up.

Host has to be reinstalled
by Jeremey Wise 23 Sep '20

23 Sep '20

Trying to repair / clean up HCI deployment so it is HA and ready for "production". I have gluster now showing three bricks all green Now I just have error on node.. and of course the node which is hosting the ovirt-engine # (as I can not send images to this forum... I will move to a breadcrumb posting) Compute -> Hosts -> "thor" (red exclamation) "Host has to be reinstalled" To fix gluster... i had to reinstall "vdsm-gluster" But what package does this error need to be reviewed / fixed with? -- penguinpages

CLI for HCI setup
by Michael Thomas 23 Sep '20

23 Sep '20

Is there a CLI for setting up a hyperconverged environment with glusterfs? The docs that I've found detail how to do it using the cockpit interface[1], but I'd prefer to use a cli similar to 'hosted-engine --deploy' if it is available. Thanks, --Mike [1]https://www.ovirt.org/documentation/gluster-hyperconverged/chap-Deploying…

info on iSCSI connection setup in oVirt 4.4
by Gianluca Cecchi 23 Sep '20

23 Sep '20

Hello, supposing to have a node that connects to an iSCSI storage domain in oVirt 4.4, is there any particular requirement in the configuration of the network adapter (ifcfg-eno1 file) when I pre-configure the server OS? Eg, do I need to have it managed by NetworkManager in 4.4? Can I instead set NM_CONTROLLED=no for this controller? Thanks in advance, Gianluca

Question on "Memory" column/field in Virtual Machines list/table in ovirt GUI
by KISHOR K 23 Sep '20

23 Sep '20

Hi, Memory field/column for few of VMs in our ovirt (Compute -> Virtual Machines -> Memory column) shows more than 90%. But, when I checked (from free and also other commands) the actual "used" memory by those VMs, it is less than 60%. What I see (from free -h) is that ovirt seems to be considering both "used" + "buff/cache" memory and is reporting the same in GUI. Isn't it the "available" memory that should be considered, because that is the actual memory available and cache memory is something that is adjusted every time? :~> free -h total used free shared buff/cache available Mem: 15Gi 6.8Gi 724Mi 310Mi 8.1Gi 9.2Gi Swap: 0B 0B 0B Can someone help to answer. Thanks ! /Kishore

console breaks with signed SSL certs
by Philip Brown 23 Sep '20

23 Sep '20

Chrome didnt want to talk AT ALL to ovirt with self-signed certs (Because HSTS is enabled) So I installed signed wildcard certs to the engine, and the nodes, following http://187.1.81.65/ovirt-engine/docs/manual/en-US/html/Administration_Guide… and https://cockpit-project.org/guide/172/https.html and chrome is happy now... except that suddenly, consoles refuse to work. and there are no useful errors that I see, other than "Unable to connect to the graphic server" from the remote viewer app. I see someone not too long ago had the exact same problem, in https://www.mail-archive.com/users@ovirt.org/msg58814.html but.. no answer was given to him?

Where is getting this filter. I have done gdisk /dev/sdc ( new 1TB Drive) and shows no partition. I even did a full dd if=/dev/zero and no change. I reloaded OS on system to get through wizard setup. Now that all three nodes are in the HCI cluster.. all six drives (2 x 1TB in each server) are now locked from any use due to this error about filter. Ideas? -- jeremey.wise(a)gmail.com

oVirt - KVM QCow2 Import
by Jeremey Wise 22 Sep '20

22 Sep '20

I rebuilt my lab environment. And their are four or five VMs that really would help if I did not have to rebuild. oVirt as I am now finding when it creates infrastructure, sets it out such that I cannot just use older means of placing .qcow2 files in folders and .xml files in other folders.... and they show up on services restarting. How do I import VMs from files? I found this article but implies VM is running: https://www.ovirt.org/develop/release-management/features/virt/KvmToOvirt.h… https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.1/ht… I need a way to import a file. Even if it means temporarily hosting on "KVM on one of the hosts to then bring in once it is up. Thanks -- penguinpages

Hi everyone, I am writing for support regarding the ovirt upgrade. I am using Ovirt with version 4.2 on CentOS 7.4 operating system. The latest release of the Ovirt engine is 4.4 which is available for CentOS 8.Can I upgrade without upgrading the operating system to centos8? I would not be wrong but it is not possible to switch from Centos7 to Centos8 .....Can anyone give me some advice?Thank you all!!!
