Self hosted to bare metal engine
by Christophe TREFOIS 25 Jul '18

25 Jul '18

Hi, What would be the process to go from self hosted engine to bare metal engine? (Actually it would move to a VM in a VMware cluster) All user guides I found are from bare metal to self hosted. Thanks for any tips or pointers Christophe Sent from my iPhone

Cannot switch to maintenance, image transfer is in progress
by Randy Bender 25 Jul '18

25 Jul '18

We've just updated our hosted engine to 4.2.4. When trying to place one of the hosts in maintenance mode, we get the error in the subject line. I've found the following that looks to be the issue we are hitting: https://bugzilla.redhat.com/show_bug.cgi?id=1586126 I've looked in the engine database with the following command and results: engine=# select disk_id from image_transfers ; disk_id -------------------------------------- 52966b71-2d01-4a16-9830-65a888717656 c72d64b7-93c9-485b-b031-29c785c5bf9a (2 rows) Full details on these records show that they are indeed old - there are no transfers actually in progress. Can anyone confirm the correct way to remedy this? The bug report notes changing the phase on the record in question. Before I try that, I'd like confirmation if anyone else has seen this issue and resolved it. And if this is the resolution, can you describe the exact psql commands to achieve this? Thanks

Freshly installed ovirt-node-ng 4.2.4 unable to deploy hosted-engine
by Ralf Schenk 25 Jul '18

25 Jul '18

Hello List, after having freshly installed my first ovirt-node-ng 4.2.4 configuring basic networking and preparing NFS Shares on my NFS-Server I would like to deploy hosted engine on this first host and NFS Storage. In Cockpit I set Performance Profile to "virtual host" and mounted an export from my Sotrage as /mnt/engine (Which shouldn't be needed since I expected the engine-setup wizard to ask me...) I'm, already stuck when selecting "Hosted Engine Deploy oVirt hosted engine on storage that has already been provisioned": save image "hosted-engine-setup" on the command-line is not available. Furthermore I've warnings in Node Health Status. I didn't configure discard anywhere. It is used as it was set up by the installer on the logical volumes residing on a SATA Disk. save image save image -- *Ralf Schenk* fon +49 (0) 24 05 / 40 83 70 fax +49 (0) 24 05 / 40 83 759 mail *rs(a)databay.de* <mailto:rs@databay.de> *Databay AG* Jens-Otto-Krag-Straße 11 D-52146 Würselen *www.databay.de* <http://www.databay.de> Sitz/Amtsgericht Aachen • HRB:8437 • USt-IdNr.: DE 210844202 Vorstand: Ralf Schenk, Dipl.-Ing.

interface up when not used
by Fabrice Bacchella 25 Jul '18

25 Jul '18

To monitoring the network interfaces, I have a script that check if ifAdminStatus and ifOperStatus values matches in snmp. But with oVirt it fails on a server with 4 physical interfaces, but only two connected, and return an error: snmptable XXX IF-MIB::ifTable | less SNMP table: IF-MIB::ifTable ifIndex ifDescr ifAdminStatus ifOperStatus 1 lo up up 2 eth0 up up 3 eth1 up up 4 eth2 up down 5 eth3 up down 24 ;vdsmdummy; down down 25 vnet0 up up And indeed on the server: ip link show eth2 4: eth2: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000 link/ether 40:a8:f0:30:81:1a brd ff:ff:ff:ff:ff:ff It's up, but I don't configured it on oVirt, removed ifcg-eth2. Is there a way to disable it ?

Sync LDAP users in Ovirt
by Hari Prasanth Loganathan 25 Jul '18

25 Jul '18

Hi Team, Good Morning. I configured the ovirt with LDAP setup. Is there an *oVirt tool* (or any way) to add all the users from LDAP to Ovirt? *Observation* : 1) I am able to see that when I try to login with the user from LDAP, that user is added in Ovirt database, So Is there a way to sync all the users from LDAP to Ovirt using any oVirt tool or API? Any help is much appreciated.

Raid configuration for single instance
by Leo David 25 Jul '18

25 Jul '18

Hello everyone, Based on your experiance or well know best practices can you provide me with an advice on raid configuration ? I have a single server, that will have a couple of brand new enterprise grade ssds, spinning and one pci nvme card. The server ( Dell PE r630 ) comes wirt Perc h730p raid controller with 2gb cache. I am thinking of creating a raid 1 array with the 2 of ssd's and ne raid10 array woth the rest of for spinning hdds. Then different gluster volume on each, to provide me 2 ( ssd / sata ) storage domains. What do you think on haveing raid1 / raid10 as underlying HA storage for gluster volumes ? At the moment a have some consumer devices ( samsung evo & seagate spinning shingled type ) and about every day the vms get into "VM has been paused due to storage IO errors" - i am thinking because of bad type hdds. Any thoughts on these ? Thank you , Leo -- Best regards, Leo David

Deleting master storage
by jin&hitman&Barracuda 25 Jul '18

25 Jul '18

Hi, Trying to build an ovirt system and i'm stuck with storage problem. I've prepared iscsi storage and seems like my storage had some troubles and now i could not get it online again. That is another story. I just want to delete master storage domain on ovirt manager. Looks like this is not allowed since there is no storage domain candidate to take master role. Also i could not add another storage domain becouse that is not allowed too. It says "can not add because there is no active storage domain" or something similar. Basically i'm stuck and don't know how to delete storage domain (master) without tear down all of them.

Backup Strategies
by Markus Schaufler 25 Jul '18

25 Jul '18

Hi! We use in our test infrastructure a NetApp shared fc storage and wonder how a backup strategie could look like. Full backups aren't the problem - trigger HV Snapshots including guest FS freeze / quiece, trigger NetApp Snapshot, delete HV Snapshots. Currently I'm struggeling on how to recover those Backups. I would provide the Snapshot volume to the hosts and import it as a new data domain, so the hosts have the snapshot disks as logical volumes. But how could I recover respectively move the content of the snapshot volumes onto the currently used vm "disk volumes"? If I have the proof of concept then scripting it to make this process more comfortable wouldn't be a problem. How do you do your backups with shared san? How can I provide incremental Backups? Thanks for any help!
