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!

Xen Free Edition migration to oVirt
by Sandro Bonazzola 24 Jul '18

24 Jul '18

Hi, If you were using Xen Free Edition or if you are still using it, after https://xenserver.org/blog/entry/xenserver-7-3-changes-to-the-free-edition.… you may be looking at oVirt as alternative. A community tool to ease the migration exist here: https://github.com/zipurman/oVIRT_Simple_Backup. Did you migrate to oVirt or are you planning it? I was wondering if it may help organizing an hackathon day for helping users doing the migration would make sense, so I'd like to know if there are users looking for assistance in the migration process. Let us know! -- SANDRO BONAZZOLA MANAGER, SOFTWARE ENGINEERING, EMEA R&D RHV Red Hat EMEA <https://www.redhat.com/> sbonazzo(a)redhat.com <https://red.ht/sig>

How to keep VM running when a storage domain is offline
by Matthew B 24 Jul '18

24 Jul '18

Hello, I am trying to understand how I can prevent a VM from being paused when one of it's disks is unavailable due to a problem with the storage domain. The scenario: A VM with 3 disks. OS disk on a highly available domain. And Two large disks each on separate domains. (so a total of 3 domains). The two large disks are mirrored using ZFS - but when one of the storage domains goes down the VM pauses. Is is possible to configure the VM to not pause when certain storage domains are unavailable? So instead of getting Paused due to IO error the disk would just be missing until that domain was brought back online? Thanks, -Matthew
