interface up when not used
by Fabrice Bacchella
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
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.
Thanks,
Hari

Raid configuration for single instance
by Leo David
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

Deleting master storage
by jin&hitman&Barracuda
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
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!

It appears you have permission issues on your storage.
I see you are using storageType='LOCALFS'
per https://www.ovirt.org/documentation/admin-guide/chap-Storage/
"Ensure that the directory has permissions allowing read/write access to the vdsm user (UID 36) and kvm group (GID 36)."
Can you verify that?

See here https://www.ovirt.org/documentation/admin-guide/chap-Backups_and_Migration/
If you want to avoid the backup/restore you can try reinstalling some of the packages:
yum reinstall ovirt-engine-wildfly
and run engine-setup.

I recommend you do an engine-backup, clean up the os (yum update, ensure proper ovirt repo for you version) and do engine-setup and restore.

Is your engine functioning at all? I'm not sure if you're saying your entire engine doesn't work, or just host deploy doesn't work.
What version of ovirt engine is this?
How did you install -- fresh installation, upgrade? From source or rpm?
Best wishes,
Greg

How to keep VM running when a storage domain is offline
by Matthew B
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
