Problem with Glusterfs Distributed-Replicated volume almost full but only less than 50% used by files.
by Olivier 22 Jul '24

22 Jul '24

Hi, I have a weird problem with my couple Glusterfs-oVirt: I had two data domain for my VMs on oVirt. The main one (data) is a Distributed-Replicate with 2 x 3 = 6 bricks of ~ 1,4 Tb on 3 servers (2 bricks by server). It was an extend of a previous 1 x 3 = 3 Replicated volume on the same servers. I had one new disk (and one new brick) on each of these 3 servers. My concern is the reported use of this volume (almost 100%). a df -h give me : df -h . Filesystem Size Used Avail Use% Mounted on ovirt1.pmmg.priv:/data 3.4T 3.3T 84G 98% /rhev/data-center/mnt/glusterSD/ovirt1.pmmg.priv:_data but a du of the same partition give me : du -hs /rhev/data-center/mnt/glusterSD/ovirt1.pmmg.priv:_data 1.4T /rhev/data-center/mnt/glusterSD/ovirt1.pmmg.priv:_data and there no hidden folder I could miss in this mount point. The weird point (the second one) is when I delete a VMs and is disks (main disk and snapshot) I doesn't get back some space on these volume. Does anyone have an idea of these problem ? Thank's Here the Info of the gluster volume : gluster volume info data Volume Name: data Type: Distributed-Replicate Volume ID: 22b7942e-2952-40d4-ab92-64636e3ce409 Status: Started Snapshot Count: 0 Number of Bricks: 2 x 3 = 6 Transport-type: tcp Bricks: Brick1: ovirt1.pmmg.priv:/gluster_bricks/data/data Brick2: ovirt2.pmmg.priv:/gluster_bricks/data/data Brick3: ovirt3.pmmg.priv:/gluster_bricks/data/data Brick4: ovirt1.pmmg.priv:/gluster_bricks/data_extend1/data Brick5: ovirt2.pmmg.priv:/gluster_bricks/data_extend1/data Brick6: ovirt3.pmmg.priv:/gluster_bricks/data_extend1/data Options Reconfigured: features.shard-block-size: 128MB cluster.lookup-optimize: off server.keepalive-count: 5 server.keepalive-interval: 2 server.keepalive-time: 10 server.tcp-user-timeout: 20 performance.client-io-threads: on nfs.disable: on storage.fips-mode-rchecksum: on transport.address-family: inet performance.quick-read: off performance.read-ahead: off performance.io-cache: off performance.low-prio-threads: 32 network.remote-dio: disable cluster.eager-lock: enable cluster.quorum-type: auto cluster.server-quorum-type: server cluster.data-self-heal-algorithm: full cluster.locking-scheme: granular cluster.shd-max-threads: 8 cluster.shd-wait-qlength: 10000 features.shard: on user.cifs: off cluster.choose-local: off client.event-threads: 4 server.event-threads: 4 storage.owner-uid: 36 storage.owner-gid: 36 network.ping-timeout: 20 performance.strict-o-direct: on cluster.granular-entry-heal: enable features.trash: off

Hi, Do you have chance to implement the PVLAN functionality with OVN for oVirt newer location?

Yes, I have only the gold crown on the host where the hosted engine is running. On the second host, there is no crown; that field is empty. When I installed it, I deployed the hosted engine on the host where I have the gold crown. After this step, I created the cluster and added the second host. Do I need to perform any additional steps every time I add a new host to the cluster to be able to migrate the hosted engine VM?

The "crown" symbol is on the host where the engine-host vm is running.

Hosted engine deployment fails on Rocky Linux 9
by mpelicci＠cisco.com 18 Jul '24

18 Jul '24

Trying to do a fresh install of ovirt 4.5 on a Rocky Linux 9 host. While running the hosted-engine --deploy --4, I input all of the information. Why is it that the hosted engine is trying to reach out to the CentOS8 repos and is there a way for me to pause the deployment to modify the repo files on the vm? [ INFO ] TASK [ovirt.ovirt.engine_setup : Install oVirt Engine package] [ ERROR ] fatal: [localhost -> 192.168.1.103]: FAILED! => {"changed": false, "msg": "Failed to download metadata for repo 'centos-ceph-pacific': Cannot prepare internal mirrorlist: Curl error (6): Couldn't resolve host name for http://mirrorlist.centos.org/?release=8-stream&arch=x86_64&repo=storage-cep… [Could not resolve host: mirrorlist.centos.org]", "rc": 1, "results": []} [root@lab-node1]# cat /etc/rocky-release Rocky Linux release 9.4 (Blue Onyx)

oVirt 4.5.5 compatibility with CPU
by jakov.jelinic＠adriatic.hr 18 Jul '24

18 Jul '24

Hi, We plan to install ovirt node 4.5.5 (https://resources.ovirt.org/pub/ovirt-4.5/iso/ovirt-node-ng-installer/) on our 2 new servers, but looking at the documentation (https://www.ovirt.org/documentation/installing_ovirt_as_a_self-hosted_engin…) it seems that oVirt is not compatible with our CPU Intel Xeon Silver 4410Y 12C 150 W 2 .0 GHz processor? Can you help us?

fence_rhevm with oVirt >4.5
by justindavis＠mail.utexas.edu 18 Jul '24

18 Jul '24

Hello Folks Is the "fence_rhevm" package compatible with oVirt >4.5? We're converting our legacy RHV cluster to a new install of oVirt latest with NFS backed storage. Everything has been working smoothly with the exception of the RHV-M fencing device on this newly provisioned oVirt 4.5.7 cluster with RHEL 9.4 hosts -- I haven't been able to get authentication working between the fencing device and the manager appliance. The same configuration is working on both the legacy RHV 4.4 cluster (RHV nodes) and a test oVirt 4.5.6 cluster (RHEL 8.9 hosts). The primary difference that comes to mind between my test and new cluster is that the newest one was installed with Keycloak SSO default configs while it was disabled on the older test environment. I suspect it has something to do with dropping basic auth? Assuming this is the case, can Keycloak be removed without having to rebuild the cluster? Are there any significant drawbacks to disabling it? I've found docs for converting from AAA to Keycloak, but not the reverse. I see on the mailing list that the `ovirt-aaa-jdbc-tool` is deprecated and that Keycloak is strongly recommended moving forward -- is it possible to integrate an internal Keycloak implementation with the existing "fence_rhevm" package? The errors I'm seeing are: 401 Unauthorized This server could not verify that you are authorized to access the document requested. Either you supplied the wrong credentials (e.g., bad password), or your browser doesn't understand how to supply the credentials required. I've tried every variation of the <domain> value suggested -- including "admin@internal", "admin@ovirt@internal", "@admin@ovirt@internal-authz" Thanks in advance, Justin
