Re: [ovirt-users] Upgrading from Hosted Engine 3.6 to 4.X

2017-11-22 Thread Cam Wright
Thanks for your response. Good to know that what I've suggested isn't
completely whacky!

> You didn't mention if you can stand downtime for your VMs or not.
We can't afford a lot of downtime on the VMs, probably 1-2 hours early
morning at maximum given business needs, but we'd prefer to not have
any downtime if at all possible.

...on your suggested plan, as that seems the more sane option if we
can get a bigger maintenance window than the aforementioned couple of
hours.
The biggest issue I can see even in step one, however, is that all of
our hosts are hosted-engine hosts, in that all four hosts are capable
of running the engine.. so we'd need to bring both clusters (i.e.: all
hosts) down.

Having said that, it seems like a safer plan... as long as business
requirements can accommodate.

Thanks again.

[ovirt-users] VDSM multipath.conf - prevent automatic management of local devices

2017-11-22 Thread Ben Bradley

Hi All

I have been running ovirt in a lab environment on CentOS 7 for several 
months but have only just got around to really testing things.
I understand that VDSM manages multipath.conf and I understand that I 
can make changes to that file and set it to private to prevent VDSM 
making further changes.


I don't mind VDSM managing the file but is it possible to set to prevent 
local devices being automatically added to multipathd?


Many times I have had to flush local devices from multipath when they 
are added/removed or re-partitioned or the system is rebooted.
It doesn't even look like oVirt does anything with these devices once 
they are setup in multipathd.


I'm assuming it's the VDSM additions to multipath that are causing this. 
Can anyone else confirm this?


Is there a way to prevent new or local devices being added automatically?

Regards
Ben

gluster storage operations are using fuse mount - so every write:
- travel to the kernel
- travel back to the gluster fuse helper process
- travel to all 3 replicas - replication is done on client side
- return to kernel when all writes succeeded
- return to caller

So gluster will never set any speed record.

Additionally, you are copying from raw lv on FC - qemu-img cannot do
anything
smart and avoid copying unused clusters. Instead if copies gigabytes of
zeros
from FC.

However 7.5-10 MiB/s sounds too slow.

I would try to test with dd - how much time it takes to copy
the same image from FC to your gluster storage?

dd
if=/rhev/data-center/2ff6d0ee-a10b-473d-b77c-be9149945f5f/ff3cd56a-1005-4426-8137-8f422c0b47c1/images/ba42cbcc-c068-4df8-af3d-00f2077b1e27/c57acd5f-d6cf-48cc-ad0c-4a7d979c0c1e

bs=8M oflag=direct status=progress

If dd can do this faster, please ask on qemu-discuss mailing list:
https://lists.nongnu.org/mailman/listinfo/qemu-discuss

If both give similar results, I think asking in gluster mailing list
about this can help. Maybe your gluster setup can be optimized.

Basically yes. You might be able to somehow patch it to enforce
this, not sure it's worth it.

Sounds reasonable.

You didn't mention if you can stand downtime for your VMs or not.
If not, or if you need to minimize it, you should design and test carefully.

If you can, something like this should work:

1. Take down all VMs on all hosts that are hosted-engine hosts
2. Move all hosted-engine hosts to maintenance
3. Remove one hosted-engine host from the engine
4. Take a backup
5. Reinstall the host as el7
6. Deploy new hosted-engine on new storage on this host, tell it to
not run engine-setup
7. Inside the new engine vm, restore the backup and engine-setup
8. See that you can start the VMs on the new host
9. Remove the other host on that cluster, reinstall it with el7, add
10. Handle the other cluster

Plan well and test well. You can use VMs and nested-kvm for the testing.
Do not restore a backup of the real engine on a test vm that has access
to your hosts - it will try to manage them. Do the testing in an isolated
network.

Re: [ovirt-users] slow performance with export storage on glusterfs

2017-11-22 Thread Shani Leviim
Hi Jiri,
Sorry for the delay.

Do you experience the same issue for non-gluster domains?

In order to profile your gluster volume while export is in progress, follow
the instructions in this link [1].
(Please execute "gluster volume profile  start " and then "gluster
volume profile  info")

[ovirt-users] Upgrading from Hosted Engine 3.6 to 4.X

2017-11-22 Thread Cam Wright
Hi there,

We're looking to upgrade our hosted engine setup from 3.6 to 4.0 (or 4.1)...

We built the 3.6 setup a couple of years ago with Fedora 22 (we wanted
the newer-at-the-time kernel 4.4) on the hosts and engine, but when we
move to 4.X we'd like to move to EL7 on the engine (as that seems to
be the supported version) and to the oVirt Node ISO installer on the
hypervisors.

We've got only four hosts in our oVirt datacentre, configured in two clusters.

Our current idea is to take a backup of the oVirt database using the
backup-restore tool, and to take a 'dd' of the virtual disk too, for
good measure. Then upgrade the engine to 4.X and confirm that the 3.6
hosts will run, and then finally piecemeal upgrade the hosts to 4.X
using the oVirt Node ISO installer.

Looking at this page -
https://www.ovirt.org/documentation/self-hosted/chap-Maintenance_and_Upgrading_Resources/
- it seems the 'hosted-engine --upgrade-appliance' path is the best
way to do this... but because our hosts are running Fedora instead of
EL, I think that makes this option moot to us.

Is what I've suggested a valid upgrade path, or is there a more sane
way of going about this?

[ovirt-users] New post on oVirt blog: LLDP Information Now Available via the Administration Portal

2017-11-22 Thread John Marks
Hello!

Just a quick heads up that there is a new post on the oVirt blog:

LLDP Information Now Available via the Administration Portal


In a nutshell:

oVirt 4.2 now includes support for the LLDP protocol, for easy management
of network resources. The LLDP protocol simplifies life for administrators
handling complex networks. Read the post.


See you on the oVirt blog!

Best,

John

Re: [ovirt-users] oVirt node and NFS

2017-11-22 Thread Magnus Isaksson
Hi Shani,

I am currently using NFS shares on this oVirt node 4.1.6 host without problem, 
i only have one host at the moment so it is setup with self-hosted-engine.
But it is when I want to access these NFS shares from another host/client that 
I cannot connect.
So when I run “Iptables -L” I can see that the NFS port are not open.
# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source   destination
ACCEPT all  --  anywhere anywhere state

--physdev-is-bridged reject-with icmp-host-prohibited

Chain OUTPUT (policy ACCEPT)
target prot opt source   destination
ACCEPT udp  --  anywhere anywhere udp dpt:6081

My first thought was to check with firewalld, but that is not running, so how 
are these iptables rules set? And how do I add an opening for NFS?
I have checked that troubleshooting guide but it have no info about this.

Hi,

This is probably an easy thing, but I can’t seem to find the solution.

On my oVirt node 4.1 I have some NFS shares that I want other hosts to reach, 
but I noticed that the firewall is not open for that on the host.
So, how to I configure the Nodes firewall?

Hello,

oVirt 4.1.6.2-1.el7.centos

Under the datacenter section, I see no iSCSI multipathing tab.
As I'm building this new DC, could this be because this DC is not yet

Self-replying (sorry, once again), for the record :

Prerequisites

Ensure you have created an iSCSI storage domain and discovered and logged into all the paths to the iSCSI target(s).

Re: [ovirt-users] Failed to open grubx64.efi

2017-11-22 Thread Yuval Turgeman
Hi,

I checked a little more, anaconda uses blivet to detect if the machine is
EFI for its boot partition requirements, and blivet checks if
/sys/firmware/efi exists [1].
The kernel registers /sys/firmware/efi only if EFI_BOOT is enabled [2], and
this is set in on setup, when the kernel searches for an EFI loader
signature
in boot_params [3] (the signatures are defined as "EL32" and "EL64").

You can access boot_params under /sys/kernel/boot_params/data, so if you
want
to understand what's going on with your machine, you can try to use strings
to
see if it's enabled while running anaconda - on my test machine it looks
like this:


[anaconda root@localhost ~]# strings /sys/kernel/boot_params/data

EL64

fHdrS


Hope this helps :)
Yuval.

[ovirt-users] oVirt node and NFS

2017-11-22 Thread Magnus Isaksson
Hi,

This is probably an easy thing, but I can't seem to find the solution.

On my oVirt node 4.1 I have some NFS shares that I want other hosts to reach, 
but I noticed that the firewall is not open for that on the host.
So, how to I configure the Nodes firewall?

Regards
Magnus Isaksson

Hi

if issue is really only NFS blocked by firewalld on host ( so you have
correct permissions, ownerships on storage directory ), solution should be
simple as:

firewall-cmd --permanent --add-service=nfs
firewall-cmd --permanent --add-service=mountd
firewall-cmd --permanent --add-service=rpc-bind
firewall-cmd --reload

But be careful, as availability of such storage is dependable on this host.
