vdsm high mem usage
by Michael Kleinpaste 11 Sep '15

11 Sep '15

Hi everybody. So I ran into that high mem usage thing. The problem I have with patching is that this is a live system so I can't do it mid day. Can anybody tell me if it is possible to just restart the vdsm service or does the host have to be in "maintenance mode" before restarting it? It is using gluster storage, if that makes a difference as well.

strange iscsi issue

------=_Part_1904412_191957680.1441657611396 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit Hi All, I have to create a test environment for testing purposes, because we need to testing our new 10gbe infrastructure. One server that have a 10gbe nic - this is the vdsm host and ovirt portal. One server that have a 10gbe nic - this is the storage. Its connected to each other throught a dlink 10gbe switch. Everything good and nice, the server can connect to storage, I can make and run VMs, but the storage performance from inside VM seems to be 1Gb/sec only. I did try the iperf command for testing connections beetwen servers, and it was 9.40 GB/sec. I have try to use hdparm -tT /dev/mapper/iscsidevice and also it was 400-450 MB/sec. I've got same result on storage server. So: - hdparm test on local storage ~ 400 mb/sec - hdparm test on ovirt node server through attached iscsi device ~ 400 Mb/sec - hdparm test from inside vm on local virtual disk - 93-102 Mb /sec The question is : Why? ps. I Have only one ovirtmgmt device, so there are no other networks. The router is only 1gbe/sec, but i've tested and the traffic does not going through this.

Question about upgrading ovirt 3.5.3 to 3.5.4
by Jason Keltz 09 Sep '15

09 Sep '15

Hi. I have a system consisting of an engine + several hosts running 3.5.3, and I want to upgrade everything to 3.5.4. According to the release notes, all I should do is: > # yum update "ovirt-engine-setup*" > # engine-setup I did this with engine, and it seemed to upgrade okay. I'm puzzled whether this applies to the hosts as well? The release notes aren't clear to me in that respect. Thanks for any assistance! Jason.

urgent issue
by Chris Liebman 09 Sep '15

09 Sep '15

In attempting to put an ovirt cluster in production I'm running into some off errors with gluster it looks like. Its 12 hosts each with one brick in distributed-replicate. (actually 2 bricks but they are separate volumes) [root@ovirt-node268 glusterfs]# rpm -qa | grep vdsm vdsm-jsonrpc-4.16.20-0.el6.noarch vdsm-gluster-4.16.20-0.el6.noarch vdsm-xmlrpc-4.16.20-0.el6.noarch vdsm-yajsonrpc-4.16.20-0.el6.noarch vdsm-4.16.20-0.el6.x86_64 vdsm-python-zombiereaper-4.16.20-0.el6.noarch vdsm-python-4.16.20-0.el6.noarch vdsm-cli-4.16.20-0.el6.noarch Everything was fine last week, however, today various clients in the gluster cluster seem get "client quorum not met" periodically - when they get this they take one of the bricks offline - this causes VM's to be attempted to move - sometimes 20 at a time. That takes a long time :-(. I've tried disabling automatic migration and teh VM's get paused when this happens - resuming gets nothing at that point as the volumes mount on the server hosting the VM is not connected: from rhev-data-center-mnt-glusterSD-ovirt-node268.la.taboolasyndication.com: _LADC-TBX-V02.log: [2015-09-08 21:18:42.920771] W [MSGID: 108001] [afr-common.c:4043:afr_notify] 2-LADC-TBX-V02-replicate-2: Client-quorum is not met [2015-09-08 21:18:42.931751] I [fuse-bridge.c:4900:fuse_thread_proc] 0-fuse: unmounting /rhev/data-center/mnt/glusterSD/ovirt-node268.la.taboolasyndication.com: _LADC-TBX-V02 [2015-09-08 21:18:42.931836] W [glusterfsd.c:1219:cleanup_and_exit] (-->/lib64/libpthread.so.0(+0x7a51) [0x7f1bebc84a51] -->/usr/sbin/glusterfs(glusterfs_sigwaiter+0xcd) [0x405e4d] -->/usr/sbin/glusterfs(cleanup_and_exit+0x 65) [0x4059b5] ) 0-: received signum (15), shutting down [2015-09-08 21:18:42.931858] I [fuse-bridge.c:5595:fini] 0-fuse: Unmounting '/rhev/data-center/mnt/glusterSD/ovirt-node268.la.taboolasyndication.com: _LADC-TBX-V02'.

But all VM's need to be migrated or stopped for that to work. I'm not seeing any obvious network or disk errors...... Are their configuration options I'm missing?

Host loses all network configuration on update to oVirt 3.5.4
by Patrick Hurrelmann 09 Sep '15

09 Sep '15

Hi all, I just updated my existing oVirt 3.5.3 installation (iSCSI hosted-engine on CentOS 7.1). The engine update went fine. Updating the hosts succeeds until the first reboot. After a reboot the host does not come up again. It is missing all network configuration. All network cfgs in /etc/sysconfig/network-scripts are missing except ifcfg-lo. The host boots up without working networking. Using IPMI and config backups, I was able to restore the lost network configs. Once these are restored and the host is rebooted again all seems to be back to good. This has now happend to 2 updated hosts (this installation has a total of 4 hosts, so 2 more to debug/try). I'm happy to assist in furter debugging. Before updating the second host, I gathered some information. All these hosts have 3 physical nics. One is used for the ovirtmgmt bridge and the other 2 are used for iSCSI storage vlans. ifcfgs before update: /etc/sysconfig/network-scripts/ifcfg-em1 # Generated by VDSM version 4.16.20-0.el7.centos DEVICE=em1 HWADDR=d0:67:e5:f0:e5:c6 BRIDGE=ovirtmgmt ONBOOT=yes NM_CONTROLLED=no DEVICE=lo IPADDR=127.0.0.1 NETMASK=255.0.0.0 NETWORK=127.0.0.0 # If you're having problems with gated making 127.0.0.0/8 a martian, # you can change this to something else (255.255.255.255, for example) BROADCAST=127.255.255.255 ONBOOT=yes NAME=loopback /etc/sysconfig/network-scripts/ifcfg-ovirtmgmt # Generated by VDSM version 4.16.20-0.el7.centos DEVICE=ovirtmgmt TYPE=Bridge DELAY=0 STP=off ONBOOT=yes IPADDR=1.2.3.16 NETMASK=255.255.255.0 GATEWAY=1.2.3.11 BOOTPROTO=none DEFROUTE=yes NM_CONTROLLED=no HOTPLUG=no /etc/sysconfig/network-scripts/ifcfg-p4p1 # Generated by VDSM version 4.16.20-0.el7.centos DEVICE=p4p1 HWADDR=68:05:ca:01:bc:0c ONBOOT=no IPADDR=4.5.7.102 NETMASK=255.255.255.0 BOOTPROTO=none MTU=9000 DEFROUTE=no NM_CONTROLLED=no /etc/sysconfig/network-scripts/ifcfg-p3p1 # Generated by VDSM version 4.16.20-0.el7.centos DEVICE=p3p1 HWADDR=68:05:ca:18:86:45 ONBOOT=no IPADDR=4.5.6.102 NETMASK=255.255.255.0 BOOTPROTO=none MTU=9000 DEFROUTE=no NM_CONTROLLED=no /etc/sysconfig/network-scripts/ifcfg-lo ip link before update: 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: bond0: <BROADCAST,MULTICAST,MASTER> mtu 1500 qdisc noop state DOWN mode DEFAULT link/ether 46:50:22:7a:f3:9d brd ff:ff:ff:ff:ff:ff 3: em1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq master ovirtmgmt state UP mode DEFAULT qlen 1000 link/ether d0:67:e5:f0:e5:c6 brd ff:ff:ff:ff:ff:ff 4: p3p1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9000 qdisc pfifo_fast state UP mode DEFAULT qlen 1000 link/ether 68:05:ca:18:86:45 brd ff:ff:ff:ff:ff:ff 5: p4p1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9000 qdisc pfifo_fast state UP mode DEFAULT qlen 1000 link/ether 68:05:ca:01:bc:0c brd ff:ff:ff:ff:ff:ff 7: ovirtmgmt: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DEFAULT link/ether d0:67:e5:f0:e5:c6 brd ff:ff:ff:ff:ff:ff 8: ;vdsmdummy;: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT link/ether ce:0f:16:49:a7:da brd ff:ff:ff:ff:ff:ff vdsm files before update: /var/lib/vdsm /var/lib/vdsm/bonding-defaults.json /var/lib/vdsm/netconfback /var/lib/vdsm/netconfback/ifcfg-ovirtmgmt /var/lib/vdsm/netconfback/ifcfg-em1 /var/lib/vdsm/netconfback/route-ovirtmgmt /var/lib/vdsm/netconfback/rule-ovirtmgmt /var/lib/vdsm/netconfback/ifcfg-p4p1 /var/lib/vdsm/netconfback/ifcfg-p3p1 /var/lib/vdsm/persistence /var/lib/vdsm/persistence/netconf /var/lib/vdsm/persistence/netconf.1416666697752319079 /var/lib/vdsm/persistence/netconf.1416666697752319079/nets /var/lib/vdsm/persistence/netconf.1416666697752319079/nets/san1 /var/lib/vdsm/persistence/netconf.1416666697752319079/nets/san2 /var/lib/vdsm/persistence/netconf.1416666697752319079/nets/ovirtmgmt /var/lib/vdsm/upgrade /var/lib/vdsm/upgrade/upgrade-unified-persistence /var/lib/vdsm/transient File in /var/lib/vdsm/netconfback each only contained a comment: # original file did not exist /var/lib/vdsm/persistence/netconf.1416666697752319079/nets/ovirtmgmt {"nic": "em1", "netmask": "255.255.255.0", "bootproto": "none", "ipaddr": "1.2.3.16", "gateway": "1.2.3.11"} /var/lib/vdsm/persistence/netconf.1416666697752319079/nets/san1 {"nic": "p3p1", "netmask": "255.255.255.0", "ipaddr": "4.5.6.102", "bridged": "false", "mtu": "9000"} /var/lib/vdsm/persistence/netconf.1416666697752319079/nets/san2 {"nic": "p4p1", "netmask": "255.255.255.0", "ipaddr": "4.5.7.102", "bridged": "false", "mtu": "9000"} After update and reboot, no ifcfg scripts are left.

How to use ovirt-guest-agent without VDSM?
by Nick Xiao 09 Sep '15

09 Sep '15

In my environment i want to use ovirt-ga replace qemu-ga. Hypervisor is Ubuntu 14.04 (OpenStack Icehouse) and the virtual machine is Ubuntu 14.04 cloudimage. In Hypervisor launch a instance and attach a chardev, like: # ps -ef | grep guest_agent libvirt+ 2649 1 1 Sep08 ? 00:15:36 /usr/bin/qemu-system-x86_64 ... -chardev socket,id=charchannel0,path=/var/lib/libvirt/qemu/org.qemu.guest_agent.0.instance-00000210.sock,server,nowait -device virtserialport,bus=virtio-serial0.0,nr=1,chardev=charchannel0,id=channel0,name=org.qemu.guest_agent.0 ... In virtual machine was installed ovirt-guest-agent 1.0.11-1.1 and service running OK. But i don't know how to get memory usage and other information in hypervisor(OpenStack compute node)? I have failed when i try to use linux command 'socat' and python socket. I need some sample or link. Thanks a lot! Nick Xiao

why replica 3
by Richard Neuboeck 09 Sep '15

This is an OpenPGP/MIME signed message (RFC 4880 and 3156) --DtNOHPq0pvAdvxKNIida56NVOQMQS9co0 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: quoted-printable Hi oVirt group, I'm currently trying to set up an oVirt 3.6 self hosed engine on a replica 2 gluster volume. As you can imagine it fails since it expects a replica 3 volume. Since this part is hard coded during the installation this could be easily remedied but on the other hand I'm not familiar with the oVirt setup so I'm not sure if I would be disturbing something far a head that again is puzzled by the lack of a replica 3 volume. Is there a reason why it has to be exactly replica 3? Shouldn't the redundancy of the storage back end be the responsibility of the admin and therefore the option to choose (at least replicated and distributed replicated) open? I'm asking because the storage back and I'm using is kind of a 'big' thing and it's hardware is put together to facilitate the use of replica 2. Sure I could create multiple bricks on those two machines but other than a negative performance impact I would gain nothing. Since the price tag of one of those servers is quite high the likelihood of getting another one is exactly 0. So I'm sure it makes sens to you that I would rather choose my own replication level than having one predetermined.
