Change compatibility level for data center/cluster during upgrade - what exactly are we changing?
by Patrick Chiang 10 Nov '20

10 Nov '20

Hi all, From the upgrade procedure, when we completed most upgrade tasks, we have to change the compatibility level in cluster and data center, and then restart all guest VM afterwards.It seems no down time expected with these 2 changes from the procedure. I wonder what exactly we are changing (a setting in the database/file??) and most important of all, whether there will be a few seconds down time when we made those changes to "data center"? Because I worried if a data center change could lead to storage domain's down time and eventually force hypervisors, guest VM restart before expected time. (My hosts/guest VM directly use HP 3par's storage as boot disks/data disks...) Hope anyone can share any experience on this. Thank you, Patrick Chiang

[OST] Network suites fails, 6+ days runtime?
by Nir Soffer 09 Nov '20

09 Nov '20

I have a trivial patch: https://gerrit.ovirt.org/c/112068 This should not have any effect on the network tests, but I ran the tests twice, and the network suite fails in both runs: - https://jenkins.ovirt.org/blue/organizations/jenkins/ovirt-system-tests_sta… - https://jenkins.ovirt.org/blue/organizations/jenkins/ovirt-system-tests_sta… The first run waited in the queue, 1 day 12 hours then ran for 11 hours. The second run waited in the queue for 2 days 21 hours and then ran for 19 hours. This is a total of 135 hours waiting for test results! Looks like we don't have the resources to test OST patches. The current way testing 8 suites for every patch is not workable. Can someone look at the network suite failure? Should we remove it from the test matrix? Nir

How to set up a (rh)el8 machine for running OST
by Marcin Sobczyk 09 Nov '20

09 Nov '20

Hi All, there are multiple pieces of information floating around on how to set up a machine for running OST. Some of them outdated (like dealing with el7), some of them more recent, but still a bit messy. Not long ago, in some email conversation, Milan presented an ansible playbook that provided the steps necessary to do that. We've picked up the playbook, tweaked it a bit, made a convenience shell script wrapper that runs it, and pushed that into OST project [1]. This script, along with the playbook, should be our single-source-of-truth, one-stop solution for the job. It's been tested by a couple of persons and proved to be able to set up everything on a bare (rh)el8 machine. If you encounter any problems with the script please either report it on the devel mailing list, directly to me, or simply file a patch. Let's keep it maintained. Regards, Marcin [1] https://gerrit.ovirt.org/#/c/111749/

No idea if it was already fixed by a patch, or is simply a random/env issue. Is it possible to pass LIBGUESTFS_DEBUG=1 LIBGUESTFS_TRACE=1 without patching vdsm? Not sure. In any case, if this does not cause too much excess debug logging, perhaps better always pass it, to help retroactively analyze such failures. Or, patch virt-sparsify/libguestfs/whatever to always log at least enough information on failure even without passing these.

Testing image transfer and backup with OST environment
by Nir Soffer 08 Nov '20

08 Nov '20

I want to share useful info from the OST hackathon we had this week. Image transfer must work with real hostnames to allow server certificate verification. Inside the OST environment, engine and hosts names are resolvable, but on the host (or vm) running OST, the names are not available. This can be fixed by adding the engine and hosts to /etc/hosts like this: $ cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.200.2 engine 192.168.200.3 lago-basic-suite-master-host-0 192.168.200.4 lago-basic-suite-master-host-1 It would be if this was automated by OST. You can get the details using: $ cd src/ovirt-system-tests/deployment-xxx $ lago status OST keeps the deployment directory in the source directory. Be careful if you like to "git clean -dxf' since it will delete all the deployment and you will have to kill the vms manually later. The next thing we need is the engine ca cert. It can be fetched like this: $ curl -k 'https://engine/ovirt-engine/services/pki-resource?resource=ca-certificate&f…' > ca.pem I would expect OST to do this and put the file in the deployment directory. To upload or download images, backup vms or use other modern examples from the sdk, you need to have a configuration file like this: $ cat ~/.config/ovirt.conf [engine] engine_url = https://engine username = admin@internal password = 123 cafile = ca.pem With this uploading from the same directory where ca.pem is located will work. If you want it to work from any directory, use absolute path to the file. I created a test image using qemu-img and qemu-io: $ qemu-img create -f qcow2 test.qcow2 1g To write some data to the test image we can use qemu-io. This writes 64k of data (b"\xf0" * 64 * 1024) to offset 1 MiB. $ qemu-io -f qcow2 -c "write -P 240 1m 64k" test.qcow2 Since this image contains only 64k of data, uploading it should be instant. The last part we need is the imageio client package: $ dnf install ovirt-imageio-client To upload the image, we need at least one host up and storage domains created. I did not find a way to prepare OST, so simply run this after run_tests completed. It took about an hour. To upload the image to raw sparse disk we can use: $ python3 /usr/share/doc/python3-ovirt-engine-sdk4/examples/upload_disk.py -c engine --sd-name nfs --disk-sparse --disk-format raw test.qcow2 [ 0.0 ] Checking image...

[ 44.1 ] Upload completed successfully I uploaded this before I added the hosts to /etc/hosts, so the upload was done via the proxy. Yes, it took 36 seconds to create the disk. To download the disk use: $ python3 /usr/share/doc/python3-ovirt-engine-sdk4/examples/download_disk.py -c engine 5ac63c72-6296-46b1-a068-b1039c8ecbd1 downlaod.qcow2 [ 0.0 ] Connecting...

Here we create a checksum of the remote disk: $ python3 /usr/share/doc/python3-ovirt-engine-sdk4/examples/checksum_disk.py -c engine 26df08cf-3dec-47b9-b776-0e2bc564b6d5 { "algorithm": "blake2b", "block_size": 4194304, "checksum": "a79a1efae73484e0218403e6eb715cdf109c8e99c2200265b779369339cf347b" } And checksum of the downloaded image - they should match: $ python3 /usr/share/doc/python3-ovirt-engine-sdk4/examples/checksum_image.py downlaod.qcow2 { "algorithm": "blake2b", "block_size": 4194304, "checksum": "a79a1efae73484e0218403e6eb715cdf109c8e99c2200265b779369339cf347b" } Same upload to iscsi domain, using qcow2 format: $ python3 /usr/share/doc/python3-ovirt-engine-sdk4/examples/upload_disk.py -c engine --sd-name iscsi --disk-sparse --disk-format qcow2 test.qcow2 [ 0.0 ] Checking image...

[ 100.00% ] 1.00 GiB, 0.31 seconds, 3.28 GiB/s [ 30.3 ] Finalizing image transfer... [ 35.4 ] Upload completed successfully Again, creating the disk is very slow, not sure why. Probably having a storage server on a nested vm is not a good idea. We can compare the checksum with the source image since checksum are computed from the guest content: [nsoffer@ost ~]$ python3 /usr/share/doc/python3-ovirt-engine-sdk4/examples/checksum_disk.py -c engine e7ef253e-7baa-4d4a-a9b2-1a6b7db13f41 { "algorithm": "blake2b", "block_size": 4194304, "checksum": "a79a1efae73484e0218403e6eb715cdf109c8e99c2200265b779369339cf347b" } Finally, we can try real images using virt-builder: $ virt-builder fedora-32 Will create a new Fedora 32 server image in the current directory. See --help for many useful options to create different format, set root password, or install packages. Uploading this image is much slower: $ python3 /usr/share/doc/python3-ovirt-engine-sdk4/examples/upload_disk.py -c engine --sd-name nfs --disk-sparse --disk-format raw fedora-32.img [ 0.0 ] Checking image...

Using backup_vm.py and other examples should work in the same way. I posted this patch to improve nfs performance, please review: https://gerrit.ovirt.org/c/112067/ Nir

Building lago from source

I'm trying to test with ost: https://github.com/lago-project/lago/pull/815 So clone the project on the ost vm and built rpms: make make rpm The result is: lago-1.0.2-1.el8.noarch.rpm python3-lago-1.0.2-1.el8.noarch.rpm But the lago version installed by setup_for_ost.sh is: $ rpm -q lago lago-1.0.11-1.el8.noarch I tried to install lago from master, and then lago_init fail: $ lago_init /usr/share/ost-images/el8-engine-installed.qcow2 -k /usr/share/ost-images/el8_id_rsa Using images ost-images-el8-host-installed-1-202011021248.x86_64, ost-images-el8-engine-installed-1-202011021248.x86_64 containing ovirt-engine-4.4.4-0.0.master.20201031195930.git8f858d6c01d.el8.noarch vdsm-4.40.35.1-1.el8.x86_64 usage: lago [-h] [-l {info,debug,error,warning}] [--logdepth LOGDEPTH] [--version] [--out-format {default,flat,json,yaml}] [--prefix-path PREFIX_PATH] [--workdir-path WORKDIR_PATH] [--prefix-name PREFIX_NAME] [--ssh-user SSH_USER] [--ssh-password SSH_PASSWORD] [--ssh-tries SSH_TRIES] [--ssh-timeout SSH_TIMEOUT] [--libvirt_url LIBVIRT_URL] [--libvirt-user LIBVIRT_USER] [--libvirt-password LIBVIRT_PASSWORD] [--default_vm_type DEFAULT_VM_TYPE] [--default_vm_provider DEFAULT_VM_PROVIDER] [--default_root_password DEFAULT_ROOT_PASSWORD] [--lease_dir LEASE_DIR] [--reposync-dir REPOSYNC_DIR] [--ignore-warnings] VERB ... lago: error: unrecognized arguments: --ssh-key /home/nsoffer/src/ovirt-system-tests/deployment-basic-suite-master /home/nsoffer/src/ovirt-system-tests/basic-suite-master/LagoInitFile Do we use a customized lago version for ost?

Host's status how to change to UP when I execute Management--> Active command
by lifuqiong＠sunyainfo.com 05 Nov '20

05 Nov '20

Hi, I checkout ovirt-engine's code with branch 4.2; When execute Host's Management --> Active command, ovirt engine just set vds's status to "Unassigned" but how the vds's status changed to "UP" in ovirt-engine? The code in ActiveVdsCommand.executeCommand() as follows: protected void executeCommand() { final VDS vds = getVds(); try (EngineLock monitoringLock = acquireMonitorLock("Activate host")) { executionHandler.updateSpecificActionJobCompleted(vds.getId(), ActionType.MaintenanceVds, false); setSucceeded(setVdsStatus(VDSStatus.Unassigned).getSucceeded()); if (getSucceeded()) { TransactionSupport.executeInNewTransaction(() -> { // set network to operational / non-operational List<Network> networks = networkDao.getAllForCluster(vds.getClusterId()); networkClusterHelper.setStatus(vds.getClusterId(), networks); return null; }); // Start glusterd service on the node, which would haven been stopped due to maintenance if (vds.getClusterSupportsGlusterService()) { runVdsCommand(VDSCommandType.ManageGlusterService, new GlusterServiceVDSParameters(vds.getId(), Arrays.asList("glusterd"), "restart")); // starting vdo service GlusterStatus isRunning = glusterUtil.isVDORunning(vds.getId()); switch (isRunning) { case DOWN: log.info("VDO service is down in host : '{}' with id '{}', starting VDO service", vds.getHostName(), vds.getId()); startVDOService(vds); break; case UP: log.info("VDO service is up in host : '{}' with id '{}', skipping starting of VDO service", vds.getHostName(), vds.getId()); break; case UNKNOWN: log.info("VDO service is not installed host : '{}' with id '{}', ignoring to start VDO service", vds.getHostName(), vds.getId()); break; } } } } } Your Sincerely Mark Lee
