Hi, oVirt 3.4.0 alpha will be delayed due to packages dependencies issue. Maintainers are already working on this, alpha will be released just after all dependency issues will have been fixed. Details on dependency missing: on CentOS 6.5: [ovirt-3.4.0-alpha] name=Alpha builds of the oVirt 3.4 project baseurl=http://resources.ovirt.org/releases/3.4.0-alpha/rpm/EL/$releasever/ enabled=1 skip_if_unavailable=1 gpgcheck=0 # repoclosure -r ovirt-3.4.0-alpha -l ovirt-3.3.2 -l base -l epel -l glusterfs-epel -l updates -l extra -l glusterfs-noarch-epel -l ovirt-stable -n Reading in repository metadata - please wait....

Gianluca, as you are using glusterfs, and as I can see on your df output: /dev/mapper/fedora-DATA_GLUSTER 30G 23G 7.8G 75% /gluster/DATA_GLUSTER node01.mydomain:gvdata 30G 26G 4.6G 85% /rhev/data-center/mnt/glusterSD/node01.mydomain:gvdata be careful to gluster cluster.min-free-disk option, that on gluster 3.1 and 3.2 it's default option is 0% (good for you!) http://gluster.org/community/documentation//index.php/Gluster_3.2:_Setting_… but I can't find the same documentation for gluster 3.4, that I suppose you're using this gluster version on ovirt; otherwise on red hat storage documentation cluster.min-free-disk default option is 10% (bad for you): https://access.redhat.com/site/documentation/en-US/Red_Hat_Storage/2.1/html… so you fill your gvdata volume up to 90% and let we know if it's stop I/O (or only write) or we can wait for a clarification from gluster guy :-) best regards a -- Amedeo Salvati RHC{DS,E,VA} - LPIC-3 - UCP - NCLA 11 email: amedeo(a)oscert.net email: amedeo(a)linux.com http://plugcomputing.it/redhatcert.php http://plugcomputing.it/lpicert.php

[Users] virtualized engine / port to self-hosted engine
by Sven Kieske 10 Jan '14

10 Jan '14

Hi, I'm currently planning to setup a libvirt-vm to use as ovirt-engine. OS in the vm would be EL 6.5 Does anybody have any experience with such a setup? I'd also like to know if such a setup could be easily ported to the upcoming self-hosted engine feature or if a physical setup could get ported better? Thanks for any input! -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.

[Users] Creation of preallocated disk with Gluster replication
by gregoire.leroy＠retenodus.net 09 Jan '14

09 Jan '14

Hello, I have a Gluster volume in distributed/replicated mode. I have 2 hosts. When I try to create a VM with a preallocated disk, it uses 100% of the available CPU and bandwidth (I have 1 Gigabit network card). The result is I can't even create a preallocated disk because the engine detects a network failure. I get that kind of messages in /var/log/messages : " Jan 2 14:13:54 localhost sanlock[3811]: 2014-01-02 14:13:54+0100 167737 [3811]: s4 kill 21114 sig 15 count 1 Jan 2 14:13:54 localhost wdmd[3800]: test failed rem 51 now 167737 ping 167718 close 167728 renewal 167657 expire 167737 client 3811 sanlock_ef4978d6-5711-4e01-a0ec-7ffbd9 cdbe5d:1 " And that in the Ovirt Gui : " 2014-janv.-02, 15:35 Operation Add-Disk failed to complete. 2014-janv.-02, 15:35 Storage Pool Manager runs on Host HOST2 (Address: X.X.X.X). 2014-janv.-02, 15:35 Invalid status on Data Center GlusterSewan.

I understand that the creation of a 10 Go disk image generates a lot of traffic, but is there a way to limit it so that it doesn't have an impact on the production ? Furthermore, Why does it use so much CPU ressources ? I can see on my monitoring graph a big peak of CPU usage when I launched the operation (probably until 100%). Thank you, Regards, Grégoire Leroy

Re: [Users] VSDM?s logrotate makes Hosts fill up var, eventually
by Juan Pablo Lorier 09 Jan '14

Hi Dan, If my opinion is worth, I use logs all the time as my setup is evolving all the time and have issues quite often, so I rather use space in logging too much than loose information I need in regular bases. Regards,

So be warned: if you have this hardware check very carefully your network mount points inside Vms If you have already tested this configuration and have this working please let me know. Best regards Alessandro Bianchi
