Unable to put Host into Maintenance mode
by Mark Steele 16 Feb '18

16 Feb '18

I have a host that is currently reporting down with NO VM's on it or associated with it. However when I attempt to put it into maintenance mode, I get the following error: Host hv-01 cannot change into maintenance mode - not all Vms have been migrated successfully. Consider manual intervention: stopping/migrating Vms: <UNKNOWN> (User: admin) I am running oVirt Engine Version: 3.5.0.1-1.el6 *** *Mark Steele* CIO / VP Technical Operations | TelVue Corporation TelVue - We Share Your Vision 16000 Horizon Way, Suite 100 | Mt.

Username / password for ovirt-shell
by Mark Steele 16 Feb '18

16 Feb '18

Hello, I'm not the original system architect of our Cluster and I'm not able to locate any documentation regarding the username and password for our ovirt-shell CLI. Is there a config file on the HostedEngine that would point me in the right direction?

Requirements for basic host
by Mark Steele 16 Feb '18

16 Feb '18

Hello again, I'm building a new host for my cluster and have a quick question about required software for joining the host to my cluster. In my notes from a previous colleague, I am instructed to do the following: yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release35.rpm yum install ovirt-hosted-engine-setup hosted-engine --deploy We already have a HostedEngine running on another server in the cluster - so do I need to install ovirt-hosted-engine-setup and then deploy it for this server to join the cluster and operate properly? As always - thank you for your time. *** *Mark Steele* CIO / VP Technical Operations | TelVue Corporation TelVue - We Share Your Vision 16000 Horizon Way, Suite 100 | Mt.

ERROR - some other host already uses IP ###.###.###.###
by Mark Steele 16 Feb '18

16 Feb '18

Good morning, We had a storage crash early this morning that messed up a couple of our ovirt hosts. Networking seemed to be the biggest issue. I have decided to remove the bridge information in /etc/sysconfig/network-scripts and ip the nics in order to re-import them into my ovirt installation (I have already removed the hosts). One of the NIC's refuses to come up and is generating the following error: ERROR : [/etc/sysconfig/network-scripts/ifup-eth] Error, some other host (0C:C4:7A:5B:11:5C) already uses address ###.###.###.###. When I ARP on this server, I do not see that Mac address - and none of my other hosts are using it either. I'm not sure where to go next other than completely reinstalling Centos on this server and starting over. Ovirt version is oVirt Engine Version: 3.5.0.1-1.el6 OS version is CentOS Linux release 7.4.1708 (Core) Thank you *** *Mark Steele* CIO / VP Technical Operations | TelVue Corporation TelVue - We Share Your Vision 16000 Horizon Way, Suite 100 | Mt.

Partition Trouble on oVirt Node
by Matt Simonsen 16 Feb '18

16 Feb '18

Hello all, This may not be oVirt specific (but it may be) so thank you in advance for any assistance. I have a system installed with oVirt Node Next 4.1.9 that was installed to /dev/sda I had a seperate RAID Volume /dev/sdb that should not have been used, but now that the operating system is loaded I'm struggling to get the device partitioned. I've tried mkfs.ext4 on the device and also pvcreate, with the errors below. I've also rebooted a couple times and tried to disable multipathd. Is multipathd even safe to disable on Node Next? Below are the errors I've received, and thank you again for any tips. [root@node1-g6-h3 ~]# mkfs.ext4 /dev/sdb mke2fs 1.42.9 (28-Dec-2013) /dev/sdb is entire device, not just one partition! Proceed anyway? (y,n) y /dev/sdb is apparently in use by the system; will not make a filesystem here! [root@node1-g6-h3 ~]# gdisk GPT fdisk (gdisk) version 0.8.6 Type device filename, or press <Enter> to exit: /dev/sdb Caution: invalid main GPT header, but valid backup; regenerating main header from backup! Caution! After loading partitions, the CRC doesn't check out! Warning! Main partition table CRC mismatch! Loaded backup partition table instead of main partition table! Warning! One or more CRCs don't match. You should repair the disk! Partition table scan: MBR: not present BSD: not present APM: not present GPT: damaged Found invalid MBR and corrupt GPT. What do you want to do? (Using the GPT MAY permit recovery of GPT data.) 1 - Use current GPT 2 - Create blank GPT Your answer: 2 Command (? for help): n Partition number (1-128, default 1): First sector (34-16952264590, default = 2048) or {+-}size{KMGTP}: Last sector (2048-16952264590, default = 16952264590) or {+-}size{KMGTP}: Current type is 'Linux filesystem' Hex code or GUID (L to show codes, Enter = 8300): 8e00 Changed type of partition to 'Linux LVM' Command (? for help): w Final checks complete. About to write GPT data. THIS WILL OVERWRITE EXISTING PARTITIONS!! Do you want to proceed? (Y/N): y OK; writing new GUID partition table (GPT) to /dev/sdb. The operation has completed successfully. [root@node1-g6-h3 ~]# pvcreate /dev/sdb1 Device /dev/sdb1 not found (or ignored by filtering).

Virtual networks in oVirt 4.2 and MTU 1500
by Dmitry Semenov 15 Feb '18

15 Feb '18

I have a not big cluster on oVirt 4.2. Each node has a bond, that has several vlans in its turn. I use virtual networks OVN (External Provider -> ovirt-provider-ovn). While testing I have noticed that in virtual network MTU must be less 1500, so my question is may I change something in network or in bond in order everything in virtual network works correctly with MTU 1500? Below link with my settings: https://pastebin.com/F7ssCVFa -- Best regards

hosted-engine deploy 4.2.1 fails when ovirtmgmt is defined on vlan subinterface
by Kuko Armas 15 Feb '18

15 Feb '18

I'm not sure if I should submit a bug report about this, so I ask around here first... I've found a bug that "seems" related but I think it's not (https://bugzilla.redhat.com/show_bug.cgi?id=1523661) This is the problem: - I'm trying to do a clean HE deploy with oVirt 4.2.1 on a clean CentOS 7.4 host - I have a LACP bond (bond0) and I need my management network to be on vlan 1005, si I have created interface bond0.1005 on the host and everything works - I run hosted-engine deploy, and it always fails with [ ERROR ] fatal: [localhost]: FAILED! => {"attempts": 50, "changed": true, "cmd": "ip rule list | grep ovirtmgmt | sed s/\\\\[.*\\\\]\\ //g | awk '{ print $9 }'", "delta": "0:00:00.006473", "end": "2018-02-15 13:57:11.132359", "rc": 0, "start": "2018-02-15 13:57:11.125886", "stderr": "", "stderr_lines": [], "stdout": "", "stdout_lines": []} [ ERROR ] Failed to execute stage 'Closing up': Failed executing ansible-playbook - Looking at the ansible playbook, I see it's trying to look for an ip rule using a custom routing table, but I have no such rule [root@ovirt1 ~]# ip rule 0: from all lookup local 32766: from all lookup main 32767: from all lookup default - I also find that I have no "ovirtmgmt" bridge bridge name bridge id STP enabled interfaces ;vdsmdummy; 8000.000000000000 no virbr0 8000.525400e6ca97 yes virbr0-nic vnet0 - But I haven't found any reference in the ansible playbook to this network creation. - The HE VM gets created and I can connect with SSH, so I tried to find out if the ovirtmgmt network is created via vdsm from the engine - Looking at the engine.log I found this: 2018-02-15 13:49:26,850Z INFO [org.ovirt.engine.core.bll.host.HostConnectivityChecker] (EE-ManagedThreadFactory-engine-Thread-1) [15c7e33a] Engine managed to communicate wi th VDSM agent on host 'ovirt1' with address 'ovirt1' ('06651b32-4ef8-4b5d-ab2d-c38e84c2d790') 2018-02-15 13:49:30,302Z ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (EE-ManagedThreadFactory-engine-Thread-1) [15c7e33a] EVENT_ID: VLAN_ID_ MISMATCH_FOR_MANAGEMENT_NETWORK_CONFIGURATION(1,119), Failed to configure management network on host ovirt1.

Is there a way I can tell the datacenter that the management network is on vlan 1005? Should I file a bug report? Is there a workaround?
