Wrong default multipath configuration for EL6
by Patrick Hurrelmann 29 Jul '14

29 Jul '14

Hi all, after suffering from boot-failures after kernel-updates on my EL6 hosts (the ones that san boot via iscsi), I finally managed to locate the root cause of the problem: the default values as set by vdsm are incorrect for EL6 and prohibit a successful iscsi boot (the faulty multipath.conf gets embedded in the new initrd on a kernel update). Additionally the following errors are repeatedly logged on all my hosts (device ids may vary) with the default vdsm multipath config: device-mapper: table: 253:5: multipath: error getting device device-mapper: ioctl: error adding target to table device-mapper: table: 253:5: multipath: error getting device device-mapper: ioctl: error adding target to table And it all boils down to the default value set for option getuid_callout in multipath.conf. Vdsm sets it to the following: getuid_callout "/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/%n" According to the man-page and other docu the default value on EL6 is "/lib/udev/scsi_id --whitelisted --device=/dev/%n". Although the binary /sbin/scsi_id is a valid link to the target /lib/udev/scsi_id, the link itself (/sbin/scsi_id) is _not_ included in the generated initrd. The binary /lib/udev/scsi_id is indeed included and changing the default config to use /lib/udev/scsi_id instead does make it all work again. iscsi boot (after regenerating the initrd, as the multipath.conf is embedded) is back to good and the previously logged device-mapper errors are gone, too. Can someone please verify this and and apply the easy (attached) patch? --- multipath.py.orig 2014-07-29 15:24:37.643839169 +0200 +++ multipath.py 2014-07-29 15:25:06.823840362 +0200 @@ -88,9 +88,8 @@ log = logging.getLogger("Storage.Multipath") _scsi_id = utils.CommandPath("scsi_id", - "/sbin/scsi_id", # EL6 "/usr/lib/udev/scsi_id", # Fedora - "/lib/udev/scsi_id", # Ubuntu + "/lib/udev/scsi_id", # EL6, Ubuntu ) Thanks a lot and best regards Patrick -- Lobster SCM GmbH, Münchner Straße 15a, D-82319 Starnberg HRB 178831, Amtsgericht München Geschäftsführer: Dr. Martin Fischer, Rolf Henrich

oVirt 3.5 Test day 1 results.
by Alexander Wels 29 Jul '14

29 Jul '14

Sorry for being a lot late with this, but I finally got around to writing the result email. I tested: OVIRT35 - [RFE][host-deploy] support more ciphers for ssh. I did a basic engine install on Fedora 20. And I installed a minimal Fedora 20 for my host. After configuring the engine and starting it, I enabled sshd and configured the only cypher to be one that was not supported before. Then I added the host using webadmin and let it run until completion. I was able to connect to the host just fine and it came up without any issues. So in short PASS Alexander

Test-Day 3.5-2 -> Import Storage Domain
by ybronhei 29 Jul '14

29 Jul '14

Hey all, following the updated wikis - http://www.ovirt.org/Features/ImportUnregisteredEntities and http://www.ovirt.org/Features/ImportStorageDomain which describe in details the steps for import storage domain I successfully created a cluster with 1 hosts and 3 vms. (host and engine run with rhel6.5) Changed some of the details for the vms (ha, system infos, mem, cpus and more), then cleaned up the engine (ran engine-cleanup and rerun engine-setup). On clean environment I created new cluster with new storage domain (its a must currently to create new storage domain before the import - stated in the [1]). After that I imported the original sd that I used, went to import Virtual machines tab and imported all entities I had. All of the vms' details were imported successfully with the same info that I configured before the cleanup. Tried again also with templates and snapshots recovery, also worked as expected seems green to me. anything else you would like me to check in this area?

by Omer Frenkel 29 Jul '14

29 Jul '14

Hi, I was assigned to test this topic, but i don't see any info on how to start, looking at the wiki: http://www.ovirt.org/Node_Hosted_Engine there is no info, nor on the HE how-to wiki: http://www.ovirt.org/Hosted_Engine_Howto should i build the node myself on a fedora, and then run the hosted engine setup as described in the how-to? what is the expected flow for this, for a user that want to start using ovirt with hosted engine and ovirt node? Thanks, Omer.

Whenever applicable, it should focus on the work that needs to be done or the difficulties that haven't yet been solved. Summarizing recent developments is okay but it should not be more than a small portion of the overall talk. END-USER TALKS One of the big challenges as developers is to know what, where and how people actually use our software. We will reserve a few slots for end users talking about their deployment challenges and achievements. If you are using KVM in production you are encouraged submit a speaking proposal. Simply mark it as an end-user talk. As an end user, this is a unique opportunity to get your input to developers. HANDS-ON / BOF SESSIONS We will reserve some time for people to get together and discuss strategic decisions as well as other topics that are best solved within smaller groups. This time can also be used for hands-on hacking sessions if you have concrete code problems to solve. These sessions will be announced during the event. If you are interested in organizing such a session, please add it to the list at http://www.linux-kvm.org/page/KVM_Forum_2014_BOF Let people you think might be interested know about it, and encourage them to add their names to the wiki page as well.
