[ovirt-users] Re: Backup to tape

2021-08-24 Thread Tony Brian Albers
Hiya,

The API in oVirt engine actually supports creating snapshots etc. for 
backups. Check out github for scripts, i.e.:

https://github.com/luisperezmarin/oVirtVMBackup

And there are others.

There is also a commercial solution, Storware vProtect: 
https://storware.eu/products/vprotect/

And as far as backup systems go, bareos(open source) is an ok solution, 
and it also support oVirt: https://www.bareos.com/

[ovirt-users] Re: oVirt 2021 Spring survey questions

2021-04-29 Thread Tony Brian Albers
Maybe also some questions about what kind of storage people use?

Do they use a dedicated file server or something distributed like gluster?

Storage filesystems that could be used:

XFS
ZFS(FreeBSD/Solaris/Illumos/Linux)
Hammer(DragonflyBSD)
OneFS (EMC Isilon)
GPFS(IBM)
etc.

Oh, I just checked, and Bareos 20 now does agentless oVirt/RHV backups 
too. You should probably have a close look at it. It's quite simple to 
manage and very, very stable.

Hmm.. It seems that NW does not support RHV, I was quite sure though 
-but I must have remembered it wrong. I think what we used to do is use 
an oVirt python backup thing that snapshotted the VM's and then we could 
fetch the snaps via the NetWorker client on the fileserver that stores 
the snapshots.

Using a NetWorker client on all the vm's is also possible of course, and 
quite easy to maintain.


IMO the best option is probably storware, reach out to Pawel Maczka

[ovirt-users] Re: Commvault

2021-03-09 Thread Tony Brian Albers
I agree with Dan, however EMC NetWorker can also backup RHEV.

I'm not that familiar with Storware, but I know that NetWorker can do 
pretty much anything you'd like. That includes handling multiple levels 
of backup, storage tiering, multiple clones on different media, 
archiving and so on...

I'm a EMC NetWorker Implementation Engineer myself, and IMO only two 
other backup systems are real competitors to NW: NetBackup and IBM 
Tivoli(called Spectrum Protect nowadays).

All three mentioned are very expensive, but then again they are designed 
for huge enterprise deployments. They do scale all the way though, so 
they would all be usable in your installation(which is small in my 
perspective, since I was running NetWorker backup of 3500 servers to 21 
NW servers back in 2010). And smaller installations like yours won't 
cost very much.

Oh, stay away from Breakup Exec.. It sucks.

And ScumVault?  I'd never use it. I've heard too many horror stories 
about restores being impossible because the server was dependent on AD, 
which was down and had to be recovered, horrendous backup server 
database issues etc. etc.

That being said, there's also Bareos which I use for backing up one of 
our Hadoop clusters. It's open source and very stable.

Hi,

Read the docs at: https://ovirt.org/documentation/

For installation, in my experience, the most stable solution is to use a 
dedicated VM or physical host for running the oVirt engine(management 
system):
https://ovirt.org/documentation/installing_ovirt_as_a_standalone_manager_with_local_databases/

Read the instructions carefully all the way through before you start.

Have fun!

2020-01-21 Thread Tony Brian Albers
In a small environment I think the easiest way would be to use the
local machine as a host and then run the engine as a vm on a laptop or
an older PC. As long as you have memory enough it runs on pretty much
anything.

Be careful when using local storage, it's got some special 
requirements:

Well, if you can live with a regular engine(not self-hosted), this
works:

Good morning,

Check SELinux just in case.

Here's my config:

NFS server:
/etc/exports:
/data/ovirt
*(rw,sync,no_subtree_check,all_squash,anonuid=36,anongid=36)

Folder:
[root@kst001 ~]# ls -ld /data/ovirt
drwxr-xr-x 3 vdsm kvm 76 Jun  1  2017 /data/ovirt

Subfolders:
[root@kst001 ~]# ls -l /data/ovirt/*
-rwxr-xr-x 1 vdsm kvm  0 Dec 10 06:38 /data/ovirt/__DIRECT_IO_TEST__

/data/ovirt/a597d0aa-bf22-47a3-a8a3-e5cecf3e20e0:
total 4
drwxr-xr-x  2 vdsm kvm  117 Jun  1  2017 dom_md
drwxr-xr-x 56 vdsm kvm 4096 Dec  2 14:51 images
drwxr-xr-x  4 vdsm kvm   42 Jun  1  2017 master
[root@kst001 ~]#


The user:
[root@kst001 ~]# id vdsm
uid=36(vdsm) gid=36(kvm) groups=36(kvm)
[root@kst001 ~]#

And output from 'mount' on a host:
kst001:/data/ovirt on /rhev/data-center/mnt/kst001:_data_ovirt type nfs
(rw,relatime,vers=3,rsize=1048576,wsize=1048576,namlen=255,soft,nolock,

[ovirt-users] Re: Super Low VM disk IO via Shared Storage

2019-09-25 Thread Tony Brian Albers
Guys,

Just for info, this is what I'm getting on a VM that is on shared
storage via NFSv3:

--snip--
[root@proj-000 ~]# time dd if=/dev/zero of=testfile bs=4096
count=100
100+0 records in
100+0 records out
409600 bytes (4.1 GB) copied, 18.0984 s, 226 MB/s

real0m18.171s
user0m1.077s
sys 0m4.303s
[root@proj-000 ~]#
--snip--

my /etc/exports:
/data/ovirt
*(rw,sync,no_subtree_check,all_squash,anonuid=36,anongid=36)

and output from 'mount' on one of the hosts:

sto-001.kac.lokalnet:/data/ovirt on /rhev/data-center/mnt/sto-
001.kac.lokalnet:_data_ovirt type nfs
(rw,relatime,vers=3,rsize=1048576,wsize=1048576,namlen=255,soft,nolock,
nosharecache,proto=tcp,timeo=600,retrans=6,sec=sys,mountaddr=172.16.216
.41,mountvers=3,mountport=20048,mountproto=udp,local_lock=all,addr=172.
16.216.41)

connected via single 10gbit ethernet. Storage on NFS server is 8 x 4TB
SATA disks in RAID10. NFS server is running CentOS 7.6.

Maybe you can get some inspiration from this.

[ovirt-users] Re: user role

2019-09-17 Thread Tony Brian Albers
Godmorgen Kim,

Not sure this is actually doable. IMO you're trying to make a kind of
not-really-admins. 

Others might have better ideas than me, but I'd look into some sort of
provisioning tool where you can use a more fine-grained
access/permissions control.

I'm for it too. I love mailing lists but as others have pointed out
it's a nightmare to search them.

I'm also willing to spend a little time supporting it if it's phpbb

[ovirt-users] Re: Memory usage inclines

2018-12-12 Thread Tony Brian Albers
Screenshots attached

We have 2 hosts and 24 running vms, all vms are pretty small.

As you can see, top and the dashboard does not agree.

An interesting thing is that if I view the host itself in the engine,
it says under "General" that 
Max free Memory for scheduling new VMs: 413360 MB

So maybe it's some sort of caching that's using the memory.

Rebooting a host doesn't help, (I've tried that earlier) the only thing
that works is to stop all vm's, reboot all hosts at the same time and
start vm's again. Then memory usage shown in the dashboard slowly
increases over time again.

It looks like it's only in oVirt-engine that there's an issue. The host
seems happy enough.

[ovirt-users] Memory usage inclines

2018-12-10 Thread Tony Brian Albers
Hi guys,

We have a small test installation here running around 30 vms on 2
hosts.

oVirt 4.2.5.3

The hosts each have 512 GB memory, and the vms are sized with 4-8 GB
each.

I have noticed that over the last months, the memory usage in the
dashboard has been increasing and is now showing 946.8 GB used of
1007.2 GB.

What can be causing this?

TIA,

Good morning,

No, I'm afraid that won't work. oVirt does not pool the resources in 
a way that makes it possible to distribute a workload over severel hosts.

IMO there are two options for you:

1. Set up the machines identicall but let them work on each their own part
of your network, separated by subnets or something similiar.

2. Look into something like python-openvas that might make it possible for you
to automate the distribution of the workload to several hosts.

HTH

Hi Nathanaël,

Yeah, I think I'll have to just use a physical NIC for the ovirtmgmt.
Too bad, it would be nice to be able to separate it from the standard
network.

[ovirt-users] using vlan-tagged nic for ovirtmgmt

2018-11-14 Thread Tony Brian Albers
Is this possible?

I have 3 hosts with each four physical interfaces.

On one of them, I have a vlan defined which I'd like to use for
ovirtmgmt. However, after installing the host, it says that the
ovirtmgmt network is missing on it and if I try to assign ovirtmgmt I
can only do it on the physical NIC's

Any ideas?

Machine1 only has a very limited amount of RAM, so it's not usable as a
node.

And I'd like to keep the engine outside, at least for now.

[ovirt-users] non-ovirt node as gluster node

2018-11-06 Thread Tony Brian Albers
Hi guys,

I have 3 machines that I'd like to test oVirt/gluster on.

The idea is that I want two of them to be oVirt nodes and the third to
run the oVirt engine.

They all have 8 hdd's, and I'd like to use these in gluster for storing
the vm images. (on all 3 machines)

So, 
machine1 is a gluster server with oVirt engine installed
machine2 is a gluster server and oVirt node
machine3 is a gluster server and oVirt node

Is this doable?

TIA,

/tony

What about just using something like SpaceWalk for management and
FreeIPA for user management?

You're not supposed to use a oVirt node as a workstation IIRC.

It looks to me like you're doing it the wrong way around. Let me try to explain 
how I would set it up:

We have the following:

0. (you should consider using this) all hosts are in DNS, you could just use 
the DNS forwarder in your router and map the names to IP's and vice versa and 
then tell all the hosts to use the router as the only DNS server.
1. nas01.groms.local to be used as NFS server for storing virtual machines. 
2. engine01.groms.local as the oVirt engine
3. node01 as the first hypervisor
4. a NFS share on nas01, i.e. /srv/ovirt/vms

Procedure:

1. make sure that nas01 has the user vdsm with uid/gid=36 and that vdsm is 
allowed read/write access on the share(i.e. /srv/ovirt/vms) that you want to 
use for vm's.

2. in engine management, create a new storage domain:
Type: NFS
Host to use: engine01.groms.local
Export path: nas01.groms.local:/srv/ovirt/vms


That should give you a usable storage domain for your vm's.

Have you thought about using glusterfs? If hosts are physically close, 
that would probably be the best solution.

Re: [ovirt-users] Performance Issue

2018-04-18 Thread Tony Brian Albers
You need a lot faster disks to keep up with all that random I/O.

"Storage IO is average on 75 M/s Read Disk and 25 Write Disk. ( SSD
 > Raid )"

Ehm, are you running VM's on a DD box?  Why on earth would you do that?

Re: [ovirt-users] Hardware critique

Also keep in mind that extensive logging in the vm's can seriously 
impact your fs performance, so using a central syslogserver is a really 
good idea.

Re: [ovirt-users] Gluster: VM disk stuck in transfer; georep gone wonky

2018-03-20 Thread Tony Brian Albers
I read somewhere about clearing out wrong stuff from the UI by manually 
editing the database, maybe you can try searching for something like that.

With regards to the VM, I'd probably just delete it, edit the DB and 
remove all sorts of references to it and then recover it from backup.

Is there nothing about all this in the ovirt logs on the engine and the 
host? It might point you in the right direction.
