running engine-setup against postgresql running on non-default port
by ivan.kabaivanov＠gmail.com 26 Feb '19

26 Feb '19

Hi, I'm running Linux From Scratch and I'm compiling ovirt from source. It all builds and installs fine. However, since I may sometimes run engine-setup from within a chroot on a host that already runs ovirt-engine and postgresql on port 5432, I would like to be able to start a new instance of postgresql on port 55555 inside the chroot, run engine-setup within the same chroot, tell it to connect to postgresql on port 55555, then once set up, I would like to manually change all config files and change postgresql port from 55555 to 5432, so when I transfer this installation to a different computer postgresql will run on 5432 and ovirt-engine (and all the other components) will know to use port 5432. Trouble is, this is easier said than done. Even when I tell engine-setup to connect to 55555 something insists on connecting to 5432: [ INFO ] Installing PostgreSQL uuid-ossp extension into database [ ERROR ] Failed to execute stage 'Misc configuration': could not connect to server: No such file or directory Is the server running locally and accepting connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"? I've manually changed all the ovirt-engine and ovirt-engine-dwh files that contained 5432, to no avail. Ideas? Thanks, IvanK.

Gluster setup Problem
by Matthew Roth 26 Feb '19

26 Feb '19

I have 3 servers, Node 1 is 3tb /dev/sda, Node 2, 3tb /dev/sdb, node3 3tb /dev/sdb I start the process for gluster deployment. I change node 1 to sda and all the other ones to sdb. I get no errors however, when I get to Creating physical Volume all it does is spin forever . doesnt get any further. I can leave it there for 5 hours and doesn't go anywhere. #gdeploy configuration generated by cockpit-gluster plugin [hosts] cmdnode1.cmd911.com cmdnode2.cmd911.com cmdnode3.cmd911.com

Adding user to internalz with webadmin?
by Juhani Rautiainen 26 Feb '19

26 Feb '19

Hi! How do you add users to internalz with webadmin? I mean there is add a button in Administration->Users which opens 'Add Users and Groups'-window . Windows has 'Add'- and 'Add and close'- buttons in the bottom. Just can't figure out how they work. Pushing either of those Add-buttons just closes the window. -Juhani

Tracking down high writes in GlusterFS volume
by Jayme 26 Feb '19

26 Feb '19

Running an oVirt 4.3 HCI 3-way replica cluster with SSD backed storage. I've noticed that my SSD writes (smart Total_LBAs_Written) are quite high on one particular drive. Specifically I've noticed one volume is much much higher total bytes written than others (despite using less overall space). My volume is writing over 1TB of data per day (by my manual calculation, and with glusterfs profiling) and wearing my SSDs quickly, how can I best determine which VM or process is at fault here? There are 5 low use VMs using the volume in question. I'm attempting to track iostats on each of the vm's individually but so far I'm not seeing anything obvious that would account for 1TB of writes per day that the gluster volume is reporting.

Add compute nodes offline
by xilazz＠126.com 26 Feb '19

26 Feb '19

Hi, when I add compute nodes, I do not intend to add compute nodes to the engine controller without connecting to the external network: An error has occurred during installation of Host node5.test.com: Failed to execute stage 'Environment customization': Cannot retrieve metalink for repository: Please verify its path and try again. Do I need to manually download some offline packages in this case?

Windows service applications migrated to the ovirt platform
by xilazz＠126.com 26 Feb '19

26 Feb '19

Hi，I now have a physical machine on which I want to migrate Windows applications to the ovirt management platform. May I ask if virt-p2v can be used for migration? Does ovirt itself have a migration tool to use?

Unrecognized message received error when ISO domain is put in Maintenance
by Wood Peter 26 Feb '19

26 Feb '19

Hi all, We are running oVirt 4.1.1 on engine and nodes. The ISO storage domain is NFS. Everything has been working great for years. Now I need to move the ISO and Export domains to a different storage server. When I put the ISO domain in maintenance the Master domain and the Export domain start flipping active-non active. The Events tab in the Web UI shows this message scrolling every 30 sec. or so: "Datacenter is being initialized. Please wait for initialization to complete" ... but it never completes. It also starts cycling the SPM assignment from one node to another. As soon as I activate back the ISO domain everything calms down and no more errors are recorded in the logs. In engine.log I see this "Unrecognized message received" error: 2019-02-25 19:45:20,467-08 ERROR [org.ovirt.vdsm.jsonrpc.client.reactors.Reactor] (SSL Stomp Reactor) [] Unable to process messages Unrecognized message received 2019-02-25 19:45:20,481-08 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (DefaultQuartzScheduler6) [76363b98] EVENT_ID: IRS_BROKER_COMMAND_FAILURE(10,803), Correlation ID: null, Call Stack: null, Custom E vent ID: -1, Message: VDSM command GetStoragePoolInfoVDS failed: Unrecognized message received 2019-02-25 19:45:20,481-08 ERROR [org.ovirt.engine.core.vdsbroker.irsbroker.IrsBrokerCommand] (DefaultQuartzScheduler6) [76363b98] ERROR, org.ovirt.engine.core.vdsbroker.irsbroker.GetStoragePoolInfoVDSCommand, exception: VDSGenericExce ption: VDSNetworkException: Unrecognized message received , log id: 1635c439 2019-02-25 19:45:20,481-08 ERROR [org.ovirt.engine.core.vdsbroker.irsbroker.IrsBrokerCommand] (DefaultQuartzScheduler6) [76363b98] Exception: org.ovirt.engine.core.vdsbroker.vdsbroker.VDSNetworkException: VDSGenericException: VDSNetwor kException: Unrecognized message received In vdsm.log on the nodes I see this: 2019-02-25 19:45:29,817-0800 ERROR (upgrade/b5b7a10) [storage.StoragePool] Unhandled exception (utils:371) Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/utils.py", line 368, in wrapper return f(*a, **kw) File "/usr/lib/python2.7/site-packages/vdsm/concurrent.py", line 180, in run return func(*args, **kwargs) File "/usr/lib/python2.7/site-packages/vdsm/storage/securable.py", line 79, in wrapper return method(self, *args, **kwargs) File "/usr/share/vdsm/storage/sp.py", line 232, in _upgradePoolDomain self._finalizePoolUpgradeIfNeeded() File "/usr/lib/python2.7/site-packages/vdsm/storage/securable.py", line 77, in wrapper raise SecureError("Secured object is not in safe state") SecureError: Secured object is not in safe state And I believe that after that error it moves the SPM to another host, gets the same error and continues moving it to the next host and so on. I really need to move the ISO and Export domains to a different storage server. Any idea what is causing this or how to fix it? Appreciate any help. Thanks, -- Peter
