Systemd-Script to put the node in "maintenance" on shutdown
by Luca Bertoncello 25 Sep '15

25 Sep '15

Hi again, I'm trying to write a systemd-script (for CentOS7) in order to automatically put the host in "maintenance" on shutdown and to activate it after boot. I wrote a python-script that to that and it works so that I can start it and see the host in "maintenance" and having all VMs migrated. Unfortunately I can't call this script on shutdown/reboot and wait until all VMs are migrated and the host is in maintenance. Here my script: [Unit] Description=oVirt interface for managing host After=remote-fs.target vdsmd.service multipathd.service libvirtd.service time-sync.target iscsid.service rpcbind.service supervdsmd.service sanlock.service vdsm-network.service Wants=remote-fs.target vdsmd.service multipathd.service libvirtd.service time-sync.target iscsid.service rpcbind.service supervdsmd.service sanlock.service vdsm-network.service [Service] Type=simple RemainAfterExit=yes ExecStart=/usr/local/bin/ovirt-maintenance.sh active ExecStop=/usr/local/bin/ovirt-maintenance.sh maintenance KillMode=none [Install] WantedBy=multi-user.target Could someone help me and say what I'm doing wrong?

Virtual appliance import question/problem
by Maurice James 25 Sep '15

25 Sep '15

------=_Part_674_1103437547.1442854627811 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit I have a virtual mail security appliance that I am trying to import into oVirt 3.5.4. The appliance was built for kvm. it has a total of 5 scsi disks. I can convert and copy the OS disk only because it expands its self to full size. The first problem that I have is that the disks expand to their full size when I convert the to an oVirt format OS Disk mail.qcow2 (74M) converts to main.img (294M) Storage disks 250.qcow2 (256K) converts to 250.img (250GB) 1024.qcow2 (256K) converts to 1024.img (1TB) 2048.qcow2 (256K) converts to 2048.img (2TB) 4096.qvow2 (256K) converts to 4096.img (4TB) 8192.qcow2 (256K) converts to 8192.img (8TB) The second problem is that these disks are scsi and ti does not seem to work using the virtio-scsi selection. I tried selecting the IDE option, but there is a limit to the number of IDE disks that I can use. Virtualbox has no issues running the appliance that was distributed in the ova format. Any help would be appreciated ------=_Part_674_1103437547.1442854627811 Content-Type: text/html; charset=utf-8 Content-Transfer-Encoding: quoted-printable <html><body><div style=3D"font-family: times new roman, new york, times, se= rif; font-size: 12pt; color: #000000"><div>I have a virtual mail security a= ppliance that I am trying to import into oVirt 3.5.4.

Mounting a gluster volume as NFS is possible (the engine data storage has been mounted). I'm asking here because glusterfs comes from the ovirt3.4 rpm repository. If anyone have a hint to this problem thanks Jean-Michel

Strange disk behaviour within VMs
by Morten A. Middelthon 24 Sep '15

24 Sep '15

Hi, last Sunday I experienced a power outage with one of my two oVirt hypervisors. After power was restored I experienced some weirdness: - on one of the VMs running on this hypervisor the boot disk changed, so it was no longer able to boot. Looking at the console the VM would hang on "Booting from hard disk". After I noticed that the wrong virtual disk was marked as OS/bootable I got it booting again after correcting it to the proper boot disk. This was done from the oVirt management server. - on another VM I tried today to add another virtual disk to expand a LVM volume. In dmesg I can see the new device: [17167560.005768] vdc: unknown partition table However, when I tried to run pvcreate I got an error message saying that this was already marked as an LVM disk, and then running pvs give me the following error: # pvs Couldn't find device with uuid 7dDcyq-TZ6I-96Im-lfjL-cTUv-nff1-B11Mm7. PV VG Fmt Attr PSize PFree /dev/vda5 rit-kvm-ssweb02 lvm2 a-- 59.76g 0 /dev/vdb1 vg_syncshare lvm2 a-- 500.00g 0 /dev/vdc1 VG_SYNCSHARE01 lvm2 a-- 400.00g 0 unknown device VG_SYNCSHARE01 lvm2 a-m 1024.00g 0 As you can see there's already a PV called /dev/vdc1, as well another one named "unknown device". These two PVs belong to a VG that does NOT belong to this VM, VG_SYNCSHARE01. The uuids for these two PVs are: --- Physical volume --- PV Name unknown device VG Name VG_SYNCSHARE01 PV Size 1024.00 GiB / not usable 3.00 MiB Allocatable yes (but full) PE Size 4.00 MiB Total PE 262143 Free PE 0 Allocated PE 262143 PV UUID 7dDcyq-TZ6I-96Im-lfjL-cTUv-nff1-B11Mm7 --- Physical volume --- PV Name /dev/vdc1 VG Name VG_SYNCSHARE01 PV Size 400.00 GiB / not usable 3.00 MiB Allocatable yes (but full) PE Size 4.00 MiB Total PE 102399 Free PE 0 Allocated PE 102399 PV UUID oKSDoo-3pxU-0uue-zQ0H-kv1N-lyPa-P2M2FY The two PVs which doesn't belong on this VM actually belongs to a totally different VM. On VM number two: # pvdisplay --- Physical volume --- PV Name /dev/vdb1 VG Name VG_SYNCSHARE01 PV Size 1024.00 GiB / not usable 3.00 MiB Allocatable yes (but full) PE Size 4.00 MiB Total PE 262143 Free PE 0 Allocated PE 262143 PV UUID 7dDcyq-TZ6I-96Im-lfjL-cTUv-nff1-B11Mm7 --- Physical volume --- PV Name /dev/vdd1 VG Name VG_SYNCSHARE01 PV Size 400.00 GiB / not usable 3.00 MiB Allocatable yes (but full) PE Size 4.00 MiB Total PE 102399 Free PE 0 Allocated PE 102399 PV UUID oKSDoo-3pxU-0uue-zQ0H-kv1N-lyPa-P2M2FY As you can see, same uuid and VG name, but two different VMs. My setup: oVirt manager: oVirt 3.5 running on CentOS 6.7 oVirt hypervisors: two oVirt 3.5 servers running on CentOS 6.7 During the time of the power outage mentioned earlier I was running oVirt 3.4, but I upgraded today and rebooted the manager and both hypervisors, but NOT the VMs. Virtual machines: Debian wheezy 7.9 x86_64 Storage: HP LeftHand iSCSI I have tried to locate error messages in the logs which can be related to this behaviour, but so far no luck :( -- Morten A.
