[Users] Why choose glusterfs over iscsi for oVirt storage?

--_000_C79B906B4ECB8E46A3281AC932C805502F49039Aexchangeredfish_ Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable Hi, I'm just setting up some storage for use with oVirt and am wondering why I = might choose glusterfs rather than just exporting a raid array as iscsi. T= he oVirt team seem to be pushing gluster (though that could just be because= it's a Red Hat product). Can anyone answer this one? What I have come up with is as follows. For: - easy to expand - redundancy across storage devices/easy replication - high availablility - performance - it's kind of cool :) - maintenance? Against (these are guesses): - performance? (multiple layers of filesystems everywhere - fs in = vm + image on gluster + gluster + block filesystem) - complexity - maintenance? Any help here is appreciated. Also, does the underlying block level filesy= stem matter here? VMs running under ovirt would be typical business applic= ations - file serving (samba4), email, databases, web servers, etc. Cheers, Justin. --_000_C79B906B4ECB8E46A3281AC932C805502F49039Aexchangeredfish_ Content-Type: text/html; charset="us-ascii" Content-Transfer-Encoding: quoted-printable <html xmlns:v=3D"urn:schemas-microsoft-com:vml" xmlns:o=3D"urn:schemas-micr= osoft-com:office:office" xmlns:w=3D"urn:schemas-microsoft-com:office:word" = xmlns:m=3D"http://schemas.microsoft.com/office/2004/12/omml" xmlns=3D"http:= //www.w3.org/TR/REC-html40"><head><meta http-equiv=3DContent-Type content= =3D"text/html; charset=3Dus-ascii"><meta name=3DGenerator content=3D"Micros= oft Word 15 (filtered medium)"><style></style></head><body lang=3DEN-AU link=3D"#0563C1= " vlink=3D"#954F72"><div class=3DWordSection1>Hi,<o:p>= </o:p><o:p> </o:p>I&= #8217;m just setting up some storage for use with oVirt and am wondering wh= y I might choose glusterfs rather than just exporting a raid array as iscsi= .  The oVirt team seem to be pushing gluster (though that could just b= e because it’s a Red Hat product).  Can anyone answer this one?<= o:p></o:p><o:p> </o:p>What I have come up with is as follows.<o:p></o:p><o:p> </o:p>For:<o:p></o:p><![if= !supportLists]>-          <= /span><![endif]>easy to expand<o:p></o:p><![if !supportLi= sts]>-          </spa= n><![endif]>redundancy across storage devices/easy replication<o:p></o:p></= p><![if !supportLists]>-      &nbsp= ;   <![endif]>high availablility<o:p></o:p><![if !supportLists]>-        =   <![endif]>performance<o:p></o:p><![if !supp= ortLists]>-          = <![endif]>it’s kind of cool J<o:p></o:p><![if !supportLists]>-  &nbsp= ;       <![endif]>maintenance?<= o:p></o:p><o:p> </o:p>Against (these are guesses):<o:p></o:p><![if !supportLists]><s= pan style=3D'mso-list:Ignore'>-          <![en= dif]>performance?

[Users] API read-only access / roles
by Sander Grendelman 20 Feb '14

20 Feb '14

I'm working on (Zabbix) monitoring through the RESTful API. Which role should I assign to the monitoring user? The user only needs read access to the data but it looks like I nead to assign at least an "Admin" role to the user to be able to read data through the API. For this I've created a "AdminLoginOnly" role that only has System->Configure System->Login Permissions access. Is this the way to go for this king of configuration? Or is there a way to further minimize the permissions of this user? Another issue is that a "Login" event is generated every time the user connects through the API. This makes the "Events" pane less useful / readable. Is there a way to disable this for some users/roles?

Ok, after more investigation on agent logs and some code modification it seem that the agent is receiving commands from virtio device. As it should. I have seen commands lock-screen, shutdown, etc... But not the "login" command. Look like engine trouble... I will do more testing tomorrow. Simon

[Users] Help required: Selinux disable for ovirt iso image
by David Smith 19 Feb '14

19 Feb '14

I apologize if this comes off a little brusque, but there's really a lot of random information out there right now, to the point where i've seen it confuse not only myself but other new installers. Based on the problems I still have, I have a suggestion, and I also need some help. Again, some of this may come off as a bit of a TLDR Rant but if ovirt is to become popular, I believe my experience as a hardware engineer, software/hardware QA director/manager/engineer, may be valuable to this project. Two things keep me from getting this system working for me in a useful manner: #1, and the most important blocker: Disabling or fixing selinux, using ovirt-node-iso-3.0.3-1.1.vdsm.fc19.iso. #2, getting raritan pdu support For issue #1: I've had a lot of people say "disable selinux" or "fix selinux" all over this user list and in recent replies. This really isn't fully helpful information. Even stating "edit the /etc/selinux/config" or use the kernel boot command "selinux=0" or read some other doc on the internet. These all apply to full fledged releases, not to the ovirt iso image. The main issue is that SSHD is not being allowed through selinux by default on this image. The right thing to do would be to fix the image and re-release it, and DELETE the broken one that is currently available. However a simple doc explaining how to persist the selinux disable or fix the SSHD problem with selinux would be the easiest solution. Others ran me down the path of "edit the selinux file and persist it" which didn't work, but gave no productive help on how to make it permanent. Equally I've been told to edit the grub config and add selinux=0 to the kernel, however after attempting this, adding it manually at the grub boot causes the system not to boot, and I haven't found the *right* grub.cfg file to edit and persist to keep the changes. For issue #2: I've hacked up some of the fence-agents scripts and am in the process of attempting to figure out how to compile/set up my own local copy to verify the raritan changes. Ideally the fence-agents folks would add a "generic support" portion, which I may actually do myself as well, allowing *any* PDU with at least the usual login/password/command/logout sequence to be used. So you see, I'm not totally useless, I'm helping here. Next suggestions: A) Compatibility list B) Cleanup of old project crap For A) For each release, I suggest there be a spreadsheet or simple document that shows which ovirt ISO images are compatible with which manager versions. There could be a wiki where people can add references to bug #s that have been found and links to their solutions. Right now there are ancient docs all over google searches that send people down paths of days of turmoil to no avail. For B) When iso images or other releases are superseded because of blocking, non-operable bugs, they should either be resolved and re-released or a clear path to making them function be documented. Once a re-release is done, the old images should be wiped out or moved to a clearly marked deprecated folder. Thats my 100 cents worth, I really do appreciate the work and effort that goes into this project, it appears to be a wonderful one, I hope to make good use of it, but the initial learning curve is a real deal breaker I'm sure for many others, especially not those willing and able to spend the time hacking at it like I have for the past week. Thanks!

[Users] Live migration of VM's occasionally fails
by Steve Dainard 19 Feb '14

19 Feb '14

Quick overview: Ovirt 3.3.2 running on CentOS 6.5 Two hosts: ovirt001, ovirt002 Migrating two VM's: puppet-agent1, puppet-agent2 from ovirt002 to ovirt001. The first VM puppet-agent1 migrates successfully. The second VM puppet-agent2 fails with "Migration failed due to Error: Fatal error during migration (VM: puppet-agent2, Source: ovirt002, Destination: ovirt001)." I've attached the logs if anyone can help me track down the issue.
