Re: [Users] DL380 G5 - Fails to Activate

[Users] Glusterfs HA doubts
In oVirt 3.1 GlusterFS support was added. It was an easy way to replicate your virtual machine storage without too much hassle. There are two main howtos: * http://www.middleswarth.net/content/installing-ovirt-31-and-glusterfs-using-either-nfs-or-posix-native-file-system-engine (Robert Middleswarth) * http://blog.jebpages.com/archives/ovirt-3-1-glusterized/ (Jason Brooks). 1) What about performance? I've done some tests with rsync backups (even using the suggested --inplace rsync switch) that implies small files. These backups were done into local mounted glusterfs volumes. Backups instead of lasting about 2 hours they lasted like 15 hours long. Is there maybe something that only happens with small files and with big files performance is ok? 2) How to know the current status? In DRBD you know it checking a proc file if I remember it well. I remember too that GlusterFS doesn't have an equivalent thing and there's no evident way to know if all the files are synced. If you have tried it how do you know if both sets of virtual disks images are synced? 3) Mount dns resolution If you check Jason Brooks howto you will see that it uses a hostname for refering to nfs mount. If you want to perform HA you need your storage to be mounted and if the server1 host is down it doesn't help that the nfs mount point associated to the storage is server1:/vms/ and not server2:/vms/. Checking Middleswarth howto I think that he does the same thing. Let's explain a bit more so that understand. My example setup is the one where you have two host machines where you run a set of virtual machines on one and the other one doesn't have any virtual machine running. Where is the virtual machines storage located? It's located at the glusterfs volume. So the first one of the machines mounts the glusterfs volume as nfs (It's an example). If it uses its own hostname for the nfs mount then if itself goes down the second host isn't going to mount it when it's restarted in the HA mode. So the first one of the machines mounts the glusterfs volume as nfs (It's an example). If it uses the second host hostname for the nfs mount then if the second host goes down the virtual machine cannot access its virtual disks. A workaround for this situation which I have thought is to use /etc/hosts on both machines so that: whatever.domain.com resolves in both hosts to the host self's ip. I think that glusterfs has a way of mounting their share through -t glusterfs that somehow can ignore these hostnames problems but I haven't read it too much about it so I'm not too sure. 4) So my doubts basically are: * Has anyone setup a two host glusterfs HA oVirt cluster where storage is shared by a replicated Glusterfs volume that is shared and stored by both of them? * Does HA work when one of the host goes down? * Or does it complain about hostname as I suspect? * Any tips to ensure the best performance?

Re: [Users] Best practice to resize a WM disk image
Hey, I wanted to report that trying to dd from the storage-side always makes the VM´s OS see two itdentically small HDD's. The only work-around I´ve found that works is to create a new, bigger drive, boot the VM from a live-CD and dd from there. When rebooted after completion, the VM´s OS then sees a bigger drive that you can extend your filesystem on. A little slower procedure, having the mirroring go over the network, but works, and that´s what´s important in the end:) /Karli mån 2013-01-14 klockan 08:37 + skrev Karli Sjöberg: ons 2013-01-09 klockan 13:04 -0500 skrev Yeela Kaplan: - Original Message - From: Karli Sjöberg karli.sjob...@slu.semailto:karli.sjob...@slu.se To: Yeela Kaplan ykap...@redhat.commailto:ykap...@redhat.com Cc: Rocky rockyba...@gmail.commailto:rockyba...@gmail.com, Users@ovirt.orgmailto:Users@ovirt.org Sent: Wednesday, January 9, 2013 4:30:35 PM Subject: Re: [Users] Best practice to resize a WM disk image ons 2013-01-09 klockan 09:13 -0500 skrev Yeela Kaplan: - Original Message - From: Karli Sjöberg karli.sjob...@slu.semailto:karli.sjob...@slu.se To: Yeela Kaplan ykap...@redhat.commailto:ykap...@redhat.com Cc: Rocky rockyba...@gmail.commailto:rockyba...@gmail.com , Users@ovirt.orgmailto:Users@ovirt.org Sent: Wednesday, January 9, 2013 1:56:32 PM Subject: Re: [Users] Best practice to resize a WM disk image tis 2013-01-08 klockan 11:03 -0500 skrev Yeela Kaplan: So, first of all, you should know that resizing a disk is not yet supported in oVirt. If you decide that you must use it anyway, you should know in advance that it's not recommended, and that your data is at risk when you perform these kind of actions. There are several ways to perform this. One of them is to create a second (larger) disk for the vm, run the vm from live cd and use dd to copy the first disk contents into the second one, and finally remove the first disk and make sure that the new disk is configured as your system disk. Here you guide for the dd operation to be done from within the guest system, but booted from live. Can this be done directly from the NFS storage itself instead? Karli, it can be done by using dd (or rsync), when your source is the volume of the current disk image and the destination is the volume of the new disk image created. You just have to find the images in the internals of the vdsm host, which is a bit more tricky and can cause more damage if done wrong. You mean since the VM's and disks are called like c3dbfb5f-7b3b-4602-961f-624c69618734 you have to query the api to figure out what´s what, but other than that, you´re saying it´ll just work, so that´s good to know, since I think letting the storage itself do the dd copy locally is going to be much much faster than through the VM, over the network. Thanks! Will it matter if the disks are Thin Provision or Preallocated? As long as it's done on the base volume it doesn't matter. Well, I´ve now tested the suggested procedure and didn´t really go all the way home. 1. Created a new, bigger virtual disk than the original, 40GB. 2. Booted Win2008R2 guest and could see from DiskManager that a new, bigger drive, 80GB, had appeared. 3. Shut guest down and issued a dd from old source to new, bigger destination. 4. When started, DiskManager now sees an offline, equally small drive as the original, 40GB. There is no free space in the new drive to expand with, Windows only sees it as beeing 40GB. Have tried Refresh and Rescan, but Windows just sees two identically small disks. Suggestions? The second, riskier, option is to export the vm to an export domain, resize the image volume size to the new larger size using qemu-img and also modify the vm's metadata in its ovf, as you can see this option is more complicated and requires deeper understanding and altering of the metadata... finally you'll need to import the vm back. - Original Message - From: Rocky rockyba...@gmail.commailto:rockyba...@gmail.com To: Yeela Kaplan ykap...@redhat.commailto:ykap...@redhat.com Cc: Users@ovirt.orgmailto:Users@ovirt.org Sent: Tuesday, January 8, 2013 11:30:00 AM Subject: Re: [Users] Best practice to resize a WM disk image Its just a theoretical question as I think the issue will come for us and other users.

Even declared in python doc that:only the main thread can set a new signal handler, and the main thread will be the only one to receive signals (this is enforced by the Python signal http://docs.python.org/2/library/signal.html#module-signal module, even if the underlying thread implementation supports sending signals to individual threads). (http://docs.python.org/2/library/signal.html) But according to my test script bellow, the child process forker event if it is not the main thread, also got SIGCHILD, Will it be a python BUG or feature? Thanks for sharing your test code. After testing your script and looking into the python signal module, I found that the signal could be received by any thread! Python installs a signal handler wrapper for all user defined signal handler. The wrapper just adds the actual handler to the queue of pending calls, and the main thread check the pending calls and run the actual hander before executing the next instruction. So, the signal interruption can happens to any thread and therefore the wrapper could run in any thread. But the user-defined handler only runs in the main thread. And if the signal occurs in non main thread, the main thread will not be interrupted and the signal will only be handled when the main thread finishes the current instruction. Please correct me if I am wrong. I agree with Mark maybe we should use synchronised way to deal with child process instead of signal handler. import threading import signal import time import os from multiprocessing import Process,Pipe def _zombieReaper(signum, frame): print 'sigchild!!!' def child(): time.sleep(5) def sleepThread(): proc = Process(target=child) proc.start() pip,pop = Pipe() pip.recv()--This line will get IOError.EINTR by SIGCHLD def main(): signal.signal(signal.SIGCHLD, _zombieReaper) servThread = threading.Thread(target = sleepThread) servThread.setDaemon(True) servThread.start() time.sleep(30) if __name__ == '__main__': main() On 01/25/2013 03:20 PM, Mark Wu wrote: Great work! The default action for SIGCHLD is ignore, so there's no problems reported before a signal handler is installed by zombie reaper.

That is because for the first call validateAccess returns normally and leave a child there, when the second validateAccess call arrives and multirprocessing manager is receiving the method message, it is just the time first child exit and SIGCHLD comming, this signal interrupted multiprocessing receive system call, python managers.py should handle INTR and retry recv() like we do in vdsm but it's not, so the second one raise error.

Re: [Users] Community feedback on the new UI-plugin Framework
- Mensaje original - De: Oved Ourfalli ov...@redhat.com Hey all, We had an oVirt workshop this week, which included a few sessions about the new oVirt UI Plugin framework, including a Hackaton and a BOF session. Was there finally any video recorded of this workshop? If you find the feedback above true, or you have other comments that weren't mentioned here, please share it with us! 5. Everything should be a plugin. One trend among platform design is that everything should be a plugin. I'm not sure how it will go with oVirt but the idea is that: * Hosts tab * Virtual machines tab * GlusterFS volumes tab * Disks tab are each one of them a plugin. You should remark that as a side-effect you win two things: * People can check how standard plugins (you could make them not-uninstallable and not-being-able-to-disable) to learn how to build their own plugins * Your plugin system would be better because it would need to be improved to support all the current default plugins capabilities 6. Plugin logs Maybe an standard way of saving plugin logs through standard ovirt-engine logs and specific plugin logs. 7. Wiki Page Is there any wiki page about this UI-plugin framework so that I can add a New ideas or new features requests page link there and add these same ideas? I think that's all. Thank you, Oved P.S: I guess the slides will be uploaded sometime next week (I guess someone would have asked it soon... so now you have your answer :-) I will, for sure, take a look at them. -- -- Adrián Gibanel I.T.

You can use the plugin tooling to install an updated kmod package as long as it's in rpm format. This will ensure that it gets into both the system and the initramfs. It's an offline process that will produce a new iso that you can install or upgrade to. The tool is called edit-node and is available in the ovirt-node-tools rpm (from the ovirt.org repos) 3.

When I run it normally (spice) I almost immediately get the icon to open spice connection and the status of VM becomes Powering Up. And in spice window I can see the boot process, that completes in less than 2 minutes When I select Run once it remains for about 10 minutes in executing phase: see this image for timings comparison: https://docs.google.com/file/d/0BwoPbcrMv8mvb3FIeHExVHFibms/edit and in vm line, the status appears as down, so that I don't get the icon to connect to console.

Ok, managed to solve it. I force removed the datacenter and reinstalled
the host. I added a new local storage to it and re-created the vms (disk
images were moved and renamed from old non working local storage).
So this host is up an running again.

I've gathered some feedback we got from the different participants about the framework, and what they would like to see in the future of it. 1. People liked the fact that it is a simple framework, allowing you to do nice extensions rapidly, without the need to know complex technologies (simple javascript knowledge is all you need to know). 2. People want the framework to provide tools for adding UI components (main/sub tabs, dialogs, etc.) that aren't URL based, but are based on components we currently have in oVirt, such as grids, key-value pairs (such as the general sub-tab), action buttons in these custom tabs and etc. The main reason for that is to easily develop a plugin with an oVirt-like look-and-feel. Chris Morrissey from Netapp showed a very nice plugin he wrote that did have an oVirt-like look-and-feel, but it wasn't easy and it required him to to develop something specific for the plugin to interact with, in the 3rd party application (something similar to the work we did in the oVirt-Foreman UI-plugin). that would be great, i hope some will be contributed by ui plugin developers for others to benefit from. 3. Support adding tasks to the system - plugins may trigger asynchronous tasks behind the scene, both oVirt and external ones. oVirt tasks and their progress will be reflected in the tasks management view, but if the flows contain external tasks as well, then it would be hard to track through the oVirt UI. 4. Plugin management * The ability to see what plugins are installed... install new plugins and remove existing ones. * Change the plugin configuration through webadmin * Distinguish between public plugin configuration entries (entries the user to change), to private ones (entries it can't). showing which plugins are installed is probably easy. deployment of plugins could be a bit more tricky for distro's assuming code is distributed via packages, which are deployed by a root user. I guess that this point will be relevant for engine-plugins as well (once support for such plugins will be available) so we should consider providing a similar solution for both. Also, Chris pointed out that it should be taken into consideration as well when working on supporting HA-oVirt-engine, as plugins are vital part of the oVirt environment. If you find the feedback above true, or you have other comments that weren't mentioned here, please share it with us!

[Users] Fwd: Re: latest vdsm cannot read ib device speeds causing storage attach fail
Hi,
I reproduced this issue, and I believe it's a python bug.
1. How to reproduce:
with the test case attached, put it under /usr/share/vdsm/tests/,
run #./run_tests.sh superVdsmTests.py
and this issue will be reproduced.
2.Log analyse:
We notice a strange pattern in this log: connectStorageServer be
called twice, first supervdsm call succeed, second fails becasue of
validateAccess().
That is because for the first call validateAccess returns normally
and leave a child there, when the second validateAccess call arrives and
multirprocessing manager is receiving the method message, it is just the
time first child exit and SIGCHLD comming, this signal interrupted
multiprocessing receive system call, python managers.py should handle
INTR and retry recv() like we do in vdsm but it's not, so the second one

Re: [Users] default mutipath.conf config for fedora 18 invalid

Even though multipath.conf no longer uses getuid_callout to recognize the device's wwid, it still knows how to deal with the attribute's existence in the conf file when running multipath command (only output is to stdout which we don't use anyway, stderr empty and rc=0). The relevant patch is: http://gerrit.ovirt.org/#/c/10824/ Given your verification, and the fact that this patch is a step forward, I've taken it into vdsm master and acked it for ovirt-3.2. I trust Ben Marzinski to shout at us loudly if keeping the outdated verb is terribly wrong. I'd expect to see a future patch, adding getuid_callout only for multipath versions that actually need it. ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
