[Users] Network not sync and problems reconfiguring
by Juan Pablo Lorier 10 Jan '14

10 Jan '14

Hi, Out of the blue some of the hosts got some LNs out of sync (not the same in all of them). If I try to resync the LN, it does not show a resync option, so I took one host and detached the lns and reconfigured them. After that, ovirtmgmt is not created correctly, it does not create the vlan interface on top of the bond and also, it's adding the bond to the bridge instead of the vlan interface. I got it partially running but it's still non operational as the engine complains the host can't mount the gluster domain (it can reach the network of the other brick): [root@ovirt4 network-scripts]# gluster volume status Status of volume: glusterfs Gluster process Port Online Pid ------------------------------------------------------------------------------ Brick 192.168.128.82:/glusterfs 49154 Y 13288 Brick 192.168.128.83:/glusterfs 49154 Y 5961 NFS Server on localhost 2049 Y 4557 Self-heal Daemon on localhost N/A Y 4558 NFS Server on 192.168.128.82 2049 Y 15815 Self-heal Daemon on 192.168.128.82 N/A Y 15819 I'm not synchronizing any other host just in case this happens to the other host too.

[Users] VSDM´s logrotate makes Hosts fill up var eventually
by Karli Sjöberg 10 Jan '14

10 Jan '14

Hi! I just noticed my Hypervisor nodes starting to complain about disks almost being full. I started investigation and noticed that: # du -h /var/log/libvirtd.log 100G /var/log/libvirtd.log And many Hosts system partition had indeed become full:S Why weren´t the file rotated? Well: # ls -lah /var/log/libvirtd.log.* | wc -l 100 And the rotate policy says: /etc/logrotate.d/libvirtd ## beginning of configuration section by vdsm /var/log/libvirt/libvirtd.log { rotate 100 missingok copytruncate size 15M compress compresscmd /usr/bin/xz uncompresscmd /usr/bin/unxz compressext .xz } Now, I just handled it by changing "100" to "1000" but I think that a better default needs to be placed in general, don´t you? # rpm -qa | grep vdsm vdsm-python-4.13.0-11.el6.x86_64 vdsm-python-cpopen-4.13.0-11.el6.x86_64 vdsm-4.13.0-11.el6.x86_64 vdsm-xmlrpc-4.13.0-11.el6.noarch vdsm-cli-4.13.0-11.el6.noarch -- Med Vänliga Hälsningar ------------------------------------------------------------------------------- Karli Sjöberg Swedish University of Agricultural Sciences Box 7079 (Visiting Address Kronåsvägen 8) S-750 07 Uppsala, Sweden Phone: +46-(0)18-67 15 66 karli.sjoberg(a)slu.se

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.
