Problems with GlusterFS

26 Feb '19

Hi we are seeing a high number of errors / failures within the logs and problems with our ovirt 4.3 cluster. IS there any assumption on a possible fix? The message "E [MSGID: 101191] [event-epoll.c:671:event_dispatch_epoll_worker] 0-epoll: Failed to dispatch handler" repeated 13 times between [2019-02-26 13:53:40.653905] and [2019-02-26 13:54:04.684140] [2019-02-26 13:54:08.684591] I [rpc-clnt.c:2042:rpc_clnt_reconfig] 0-vmstore-client-2: changing port to 49153 (from 0) [2019-02-26 13:54:08.689021] E [MSGID: 101191] [event-epoll.c:671:event_dispatch_epoll_worker] 0-epoll: Failed to dispatch handler ==> /var/log/glusterfs/glustershd.log <== [2019-02-26 13:54:08.783380] I [rpc-clnt.c:2042:rpc_clnt_reconfig] 0-vmstore-client-2: changing port to 49153 (from 0) [2019-02-26 13:54:09.427338] I [rpc-clnt.c:2042:rpc_clnt_reconfig] 0-engine-client-2: changing port to 49152 (from 0) [2019-02-26 13:54:10.785533] I [rpc-clnt.c:2042:rpc_clnt_reconfig] 0-engine-client-2: changing port to 49152 (from 0) [2019-02-26 13:54:12.432411] I [rpc-clnt.c:2042:rpc_clnt_reconfig] 0-vmstore-client-2: changing port to 49153 (from 0) ==> /var/log/glusterfs/rhev-data-center-mnt-glusterSD-ovirt4-stor.creator.local:_engine.log <== [2019-02-26 13:54:12.579095] I [rpc-clnt.c:2042:rpc_clnt_reconfig] 0-engine-client-2: changing port to 49152 (from 0) ==> /var/log/glusterfs/rhev-data-center-mnt-glusterSD-ovirt4-stor.creator.local:vmstore.log <== [2019-02-26 13:54:12.689449] I [rpc-clnt.c:2042:rpc_clnt_reconfig] 0-vmstore-client-2: changing port to 49153 (from 0) ==> /var/log/glusterfs/glustershd.log <== [2019-02-26 13:54:12.790471] I [rpc-clnt.c:2042:rpc_clnt_reconfig] 0-vmstore-client-2: changing port to 49153 (from 0) [2019-02-26 13:54:13.437351] I [rpc-clnt.c:2042:rpc_clnt_reconfig] 0-engine-client-2: changing port to 49152 (from 0)

Local Storage domain to Shared
by Matt Simonsen 26 Feb '19

26 Feb '19

Hello all, I have a few nodes with local storage, and I've considered exporting them via NFS to migrate into shared storage, more than a few times. I have thought of this post on the ovirt-users list many times: https://lists.ovirt.org/pipermail/users/2017-December/085521.html Is this procedure documented & fully supported? Or is it something that just happens to work? The instructions provided by Gianluca seem very clear. If this isn't documented better, ie: a blog for the site, what are the things that I should include to make it of value for going on the site? Thanks, Matt

oVirt-4.2: HE rebooting continuously and 2 hosts non-operatinal
by Parth Dhanjal 26 Feb '19

26 Feb '19

Hey! I'm facing a problem with oVirt-4.2 HE. The HE is rebooting continuously. I tried accessing the VM through the VNC console. But it is not responding. 2 hosts are also Non-Operational. I tried debugging, but couldn't resolve it Though I found a few errors. Error in the agent log for one of the non-operational hosts - http://pastebin.test.redhat.com/721991 Error in the broker log - http://pastebin.test.redhat.com/721990 Also, I couldn't see the brick mounted on the non-op hosts. Even though the volume status seems fine. Anyone knows why is this issue occurring? Regards Parth Dhanjal

AIC JBOD RAID Disks automatically going offline under OVirt?
by nikhilbhalwankar＠yahoo.co.in 26 Feb '19

26 Feb '19

Hi, We are facing weird issue. We have a AIC JBOD with Ovirt Node installed. This Node is added under Ovirt engine. We faced issues related to RAID Disks going offline two times, 1) OVA Import from VMWare ESXi to OVirt 2) Delete existing OVirt VM which is in shutdown state In both these cases, suddenly Disks from RAID array (which we are using as Fiber Channel under OVirt) go offline. Can anybody please help what can be done in this case?

I guess you can log on ovirt2 and run hosted-engine --set-maintenance --mode=local && sleep 30 && hosted-engine --vm-status Then reinstall ovirt2 from the web UI and mark the engine for deployment. Once the reinstall is over - remove maintenance via : hosted-engine --set-maintenance --mode=none Best Regards, Strahil Nikolov

running engine-setup against postgresql running on non-default port
by ivan.kabaivanov＠gmail.com 26 Feb '19

26 Feb '19

Hi, I'm running Linux From Scratch and I'm compiling ovirt from source. It all builds and installs fine. However, since I may sometimes run engine-setup from within a chroot on a host that already runs ovirt-engine and postgresql on port 5432, I would like to be able to start a new instance of postgresql on port 55555 inside the chroot, run engine-setup within the same chroot, tell it to connect to postgresql on port 55555, then once set up, I would like to manually change all config files and change postgresql port from 55555 to 5432, so when I transfer this installation to a different computer postgresql will run on 5432 and ovirt-engine (and all the other components) will know to use port 5432. Trouble is, this is easier said than done. Even when I tell engine-setup to connect to 55555 something insists on connecting to 5432: [ INFO ] Installing PostgreSQL uuid-ossp extension into database [ ERROR ] Failed to execute stage 'Misc configuration': could not connect to server: No such file or directory Is the server running locally and accepting connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"? I've manually changed all the ovirt-engine and ovirt-engine-dwh files that contained 5432, to no avail. Ideas? Thanks, IvanK.

Gluster setup Problem
by Matthew Roth 26 Feb '19

26 Feb '19

I have 3 servers, Node 1 is 3tb /dev/sda, Node 2, 3tb /dev/sdb, node3 3tb /dev/sdb I start the process for gluster deployment. I change node 1 to sda and all the other ones to sdb. I get no errors however, when I get to Creating physical Volume all it does is spin forever . doesnt get any further. I can leave it there for 5 hours and doesn't go anywhere. #gdeploy configuration generated by cockpit-gluster plugin [hosts] cmdnode1.cmd911.com cmdnode2.cmd911.com cmdnode3.cmd911.com

Adding user to internalz with webadmin?
by Juhani Rautiainen 26 Feb '19

26 Feb '19

Hi! How do you add users to internalz with webadmin? I mean there is add a button in Administration->Users which opens 'Add Users and Groups'-window . Windows has 'Add'- and 'Add and close'- buttons in the bottom. Just can't figure out how they work. Pushing either of those Add-buttons just closes the window. -Juhani

Tracking down high writes in GlusterFS volume
by Jayme 26 Feb '19

26 Feb '19

Running an oVirt 4.3 HCI 3-way replica cluster with SSD backed storage. I've noticed that my SSD writes (smart Total_LBAs_Written) are quite high on one particular drive. Specifically I've noticed one volume is much much higher total bytes written than others (despite using less overall space). My volume is writing over 1TB of data per day (by my manual calculation, and with glusterfs profiling) and wearing my SSDs quickly, how can I best determine which VM or process is at fault here? There are 5 low use VMs using the volume in question. I'm attempting to track iostats on each of the vm's individually but so far I'm not seeing anything obvious that would account for 1TB of writes per day that the gluster volume is reporting.

Hi, when I add compute nodes, I do not intend to add compute nodes to the engine controller without connecting to the external network: An error has occurred during installation of Host node5.test.com: Failed to execute stage 'Environment customization': Cannot retrieve metalink for repository: Please verify its path and try again. Do I need to manually download some offline packages in this case?

Hi，I now have a physical machine on which I want to migrate Windows applications to the ovirt management platform. May I ask if virt-p2v can be used for migration? Does ovirt itself have a migration tool to use?

Unrecognized message received error when ISO domain is put in Maintenance
by Wood Peter 26 Feb '19

26 Feb '19

Hi all, We are running oVirt 4.1.1 on engine and nodes. The ISO storage domain is NFS. Everything has been working great for years. Now I need to move the ISO and Export domains to a different storage server. When I put the ISO domain in maintenance the Master domain and the Export domain start flipping active-non active. The Events tab in the Web UI shows this message scrolling every 30 sec. or so: "Datacenter is being initialized. Please wait for initialization to complete" ... but it never completes. It also starts cycling the SPM assignment from one node to another. As soon as I activate back the ISO domain everything calms down and no more errors are recorded in the logs. In engine.log I see this "Unrecognized message received" error: 2019-02-25 19:45:20,467-08 ERROR [org.ovirt.vdsm.jsonrpc.client.reactors.Reactor] (SSL Stomp Reactor) [] Unable to process messages Unrecognized message received 2019-02-25 19:45:20,481-08 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (DefaultQuartzScheduler6) [76363b98] EVENT_ID: IRS_BROKER_COMMAND_FAILURE(10,803), Correlation ID: null, Call Stack: null, Custom E vent ID: -1, Message: VDSM command GetStoragePoolInfoVDS failed: Unrecognized message received 2019-02-25 19:45:20,481-08 ERROR [org.ovirt.engine.core.vdsbroker.irsbroker.IrsBrokerCommand] (DefaultQuartzScheduler6) [76363b98] ERROR, org.ovirt.engine.core.vdsbroker.irsbroker.GetStoragePoolInfoVDSCommand, exception: VDSGenericExce ption: VDSNetworkException: Unrecognized message received , log id: 1635c439 2019-02-25 19:45:20,481-08 ERROR [org.ovirt.engine.core.vdsbroker.irsbroker.IrsBrokerCommand] (DefaultQuartzScheduler6) [76363b98] Exception: org.ovirt.engine.core.vdsbroker.vdsbroker.VDSNetworkException: VDSGenericException: VDSNetwor kException: Unrecognized message received In vdsm.log on the nodes I see this: 2019-02-25 19:45:29,817-0800 ERROR (upgrade/b5b7a10) [storage.StoragePool] Unhandled exception (utils:371) Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/utils.py", line 368, in wrapper return f(*a, **kw) File "/usr/lib/python2.7/site-packages/vdsm/concurrent.py", line 180, in run return func(*args, **kwargs) File "/usr/lib/python2.7/site-packages/vdsm/storage/securable.py", line 79, in wrapper return method(self, *args, **kwargs) File "/usr/share/vdsm/storage/sp.py", line 232, in _upgradePoolDomain self._finalizePoolUpgradeIfNeeded() File "/usr/lib/python2.7/site-packages/vdsm/storage/securable.py", line 77, in wrapper raise SecureError("Secured object is not in safe state") SecureError: Secured object is not in safe state And I believe that after that error it moves the SPM to another host, gets the same error and continues moving it to the next host and so on. I really need to move the ISO and Export domains to a different storage server. Any idea what is causing this or how to fix it? Appreciate any help. Thanks, -- Peter

/boot partition of oVirt node missing after reboot

Stuck completing last step of 4.3 upgrade
by Jayme 25 Feb '19

25 Feb '19

Environment setup: 3 Host HCI GlusterFS setup. Identical hosts, Dell R720s w/ Intel E5-2690 CPUs 1 default data center (4.2 compat) 1 default cluster (4.2 compat) Situation: I recently upgraded my three node HCI cluster from Ovirt 4.2 to 4.3. I did so by first updating the engine to 4.3 then upgrading each ovirt-node host to 4.3 and rebooting. Currently engine and all hosts are running 4.3 and all is working fine. To complete the upgrade I need to update cluster compatibility to 4.3 and then data centre to 4.3. This is where I am stuck. The CPU type on cluster is "Intel SandyBridge IBRS Family". This option is no longer available if I select 4.3 compatibility. Any other option chosen such as SandyBridge IBRS SSBD will not allow me to switch to 4.3 as all hosts must be in maintenance mode (which is not possible w/ self hosted engine). I saw another post about this where someone else followed steps to create a second cluster on 4.3 with new CPU type then move one host to it, start engine on it then perform other steps to eventually get to 4.3 compatibility. I tried to add a 4.3 cluster with gluster service and put one of my hosts in to maintenance mode but could not move it to the new cluster, it gave me an error about the host having gluster service. If I try to import gluster config in cluster add UI it fails in engine log with "SERVER_ALREADY_EXISTS_IN_ANOTHER_CLUSTER" My question is, what is the proper procedure for me to complete upgrading my three node HCI environment to 4.3 cluster compatibility along with changing CPU type? Do I really need to create a second cluster and move host(s) to it? If so how can I move an existing host with running gluster service to a new cluster? Thanks in advance!

Re: Ovirt Glusterfs
by Strahil 25 Feb '19

Hi Sahina, Thanks for your reply. Let me share my test results with gluster v3 . I have a 3-node hyperconverged setup with 1 Gbit/s network and SSD (sata-based) for LVM caching. Testing the bricks showed higher than the network performance. 1. Tested ovirt 4.2.7/4.2.8 with fuse mounts. Using 'dd if=/dev/zero of=/default/gluster/Mount point/from/ovirt bs=1M count=5000'. Results: 56MB/s directly on the mount point, 20+-2 MB/s from a VM. Reads on fuse mount point -> 500+ MB/s Disabling sharing increased performance from the fuse mount point, nothing beneficial from a VM. Converting the bricks of a volume to 'tmpfs' does not bring any performance gain for FUSE mount. 2. Tested ovirt 4.2.7/4.2.8 with gfapi - performance in VM -> approx 30 MB/s 3. Gluster native NFS (now deprecated) on ovirt 4.2.7/4.2.8 -> 120MB/s on mount point, 100+ MB/s in VM My current setup: Storhaug + ctdb + nfs-ganesha (ovirt 4.2.7/4.2.8) -> 80+-2 MB/s in the VM. Reads are around the same speed. Sadly, I didn't have the time to test performance on gluster v5 (ovirt 4.3.0) , but I haven't noticed any performance gain for the engine. My suspicion with FUSE is that when a gluster node is also playing the role of a client -> it still uses network bandwidth to communicate to itself, but I could be wrong. According to some people on the gluster lists, the FUSE performance is expected ,but my tests with disabled sharing shows better performance. Most of the time 'gtop' does not show any spikes and iftop shows that network usage is not going over 500 Mbit/s As I hit some issues with the deployment on 4.2.7 , I decided to stop my tests for now.

HC : JBOD or RAID5/6 for NVME SSD drives?
by Guillaume Pavese 25 Feb '19

25 Feb '19

Hi, We have been evaluating oVirt HyperConverged for 9 month now with a test cluster of 3 DELL Hosts with Hardware RAID5 on PERC card. We were not impressed with the performance... No SSD for LV Cache on these hosts but I tried anyway with LV Cache on a ram device. Perf were almost unchanged. It seems that LV Cache is its own source of bugs and problems anyway, so we are thinking going for full NVME drives when buying the production cluster. What would the recommandation be in that case, JBOD or RAID? Thanks Guillaume Pavese Ingénieur Système et Réseau Interactiv-Group

Gluster - performance.strict-o-direct and other performance tuning in different storage backends
by Leo David 25 Feb '19

25 Feb '19

Hello Everyone, As per some previous posts, this "performance.strict-o-direct=on" setting caused trouble or poor vm iops. I've noticed that this option is still part of default setup or automatically configured with "Optimize for virt. store" button. In the end... is this setting a good or a bad practice for setting the vm storage volume ? Does it depends ( like maybe other gluster performance options ) on the storage backend: - raid type / jbod - raid controller cache size I am usually using jbod disks attached to lsi hba card ( no cache ). Any gluster recommendations regarding this setup ? Is there any documentation for best practices on configurating ovirt's gluster for different types of storage backends ? Thank you very much ! Have a great week, Leo -- Best regards, Leo David

Unable to change cluster and data center compatibility version
by Jonathan Mathews 25 Feb '19

25 Feb '19

Good Day I have been trying to upgrade a clients oVirt from 3.6 to 4.0 but have run into an issue where I am unable to change the cluster and data center compatibility version. I get the following error in the GUI: Ovirt: Some of the hosts still use legacy protocol which is not supported by cluster 3.6 or higher. In order to change it a host needs to be put to maintenance and edited in advanced options section. This error was received with all VM's off and all hosts in maintenance.

Problem with snapshots in illegal status

Hello, We are experiencing some problems with some snapshots in illegal status generated with the python API. I think I'm not the only one, and that is not a relief but I hope someone can help about it. I'm a bit scared because, for what I see, the creation date in the engine for every snapshot is way different from the date when it was really created. The name of the snapshot is in the format backup_snapshot_YYYYMMDD-HHMMSS, but as you can see in the following examples, the stored date is totally random...

VM creation using python api specifying an appropriate timezone
by ckennedy288＠gmail.com 25 Feb '19

25 Feb '19

Hi, I'm looking for a way to accurately specify the timezone of a VM at VM creation time. At the moment all VMs that get created using a simple in-house python script are set with a GMT timezone e.g.: if ( "windows" in OS ): vm_tz="GMT Standard Time" else: vm_tz="Etc/GMT" Is there a better way to choose a more appropriate timezone based on the VMs global location? is there a way to get a list of ovirt supported time zones for Windows and Linux and compare that with the VMs location and OS type and then choose an appropriate timezone?

Info about AD integration and Root CA
by Gianluca Cecchi 25 Feb '19

25 Feb '19

Hello, in docs for 4.2 RHV (I think it applies to oVirt 4.2 too) for attaching to AD there is the statement " To set up secure connection between the LDAP server and the Manager, ensure a PEM- encoded CA certificate has been prepared. See Section D.2, “Setting Up Encrypted Communication between the Manager and an LDAP Server” for more information. " and in Appendix " To set up encrypted communication between the Red Hat Virtualization Manager and an LDAP server, obtain the root CA certificate of the LDAP server. . . " and in readme file referred in the Appendix (/usr/share/doc/ovirt-engine-extension-aaa-ldap-1.3.8/README) there is the command: " Active Directory Windows: > certutil -ca.cert myrootca.der Linux: $ openssl -in myrootca.der -inform DER -out myrootca.pem " In my case on Windows DC (that is a Windows 2012 R2 server with "Domain functional level: Windows Server 2003") I get this error: C:\Users\Administrator.MYDOMAIN>certutil -ca.cert mydomain.der CertUtil: The system cannot find the file specified. C:\Users\Administrator.MYDOMAIN> What does it mean exactly? Thanks in advance, Gianluca

HostedEngine Unreachable

Hi, Our cluster was running fine, until we moved it to the new network. Looking at the agent.log file, it stills pings the old gateway.

Ovirt 4.2.8.. Possible bug?
by matteo fedeli 25 Feb '19

25 Feb '19

Hi considering that the deploy with 4.2.7.8 failed I try to reinstall ovirt to version 4.2.8 and there are appened two strange things. During the volume step if i choose jbod mode in the deploy conf remain raid6 type... Why? To solve I have only tried to editing manually the file at line about volume type and the deploy stuck on creating physical volume... this is my conf file: (I used 3 HDDs 500GB each, node,engine +

I have done some testing and it seems that storhaug + ctdb + nfs-ganesha is showing decent performance in a 3 node hyperconverged setup. Fuse mounts are hitting some kind of limit when mounting gluster -3.12.15 volumes. Best Regards, Strahil Nikolov

Creating new VM
by Yujin Boby 24 Feb '19

24 Feb '19

I installed oVirt, when i try to create a new VM, it says This host is managed by a virtualization manager, so creation of new VM from this host is not possible. https://imgur.com/a/hpqV6ML Any idea why i am getting this error ? Do i need more than 1 server to create Virtual machines ? Like adding a node ?

How to recreate Ovirt CA from scratch
by Giorgio Biacchi 24 Feb '19

24 Feb '19

Hi list, during our datacenter lifetime many things changed. We moved the engine twice on different hosts with, of course, different FQDNs, and many other changes. Now we are stuck with an error when we try to upload an image to a data domain. The error is somehow bound to a failure to validate the ovirt-imageio-proxy certificate and, since the current root CA certificate is still signed with sha1WithRSAEncryption we'd like to regenerate the whole CA. That's the steps we've done.. without success... 1) Make a tar.gz of the /etc/pki/ovirt-engine as backup 2) Create a new CA cert using the same private key: openssl req -key /etc/pki/ovirt-engine/private/ca.pem -new -x509 -days 3650 -sha256 -extensions v3_ca -out newca.cert.pem 3) Put the new CA cert in place mv ca.pem ca.pem.orig.20190219;mv newca.cert.pem ca.pem 4) Resign all the other certs names="engine apache websocket-proxy jboss imageio-proxy" for name in $names; do subject="$( openssl \ x509 \ -in /etc/pki/ovirt-engine/certs/"${name}".cer \ -noout \ -subject \ | sed \ 's;subject= $.*$;\1;' \ )" /usr/share/ovirt-engine/bin/pki-enroll-pkcs12.sh \ --name="${name}" \ --password=mypass \ --subject="${subject}" \ --keep-key done 5) Restart all the services systemctl restart httpd systemctl restart ovirt-engine systemctl restart ovirt-websocket-proxy systemctl restart ovirt-imageio-proxy The following step was to take the backup at 1) and fall back to the initial state because nothing worked as expected. There's any documented procedure about how to recreate Ovirt CA from scratch??

Hi Guys, I am trying to install oVirt node on a physical machine. Once selected the option to install oVirt 4.3 it give a screen "dracut-initqueue time out And then get into emergency mode & gives dracut cmd line. if I exit the command line, it continue boot into the installation window. However it gives a message "Kickstart file /run/install/ks.config is missing" (Pane is dead). Tried the same on vmware, it boot fine & am able to install it. Can someone tell me how could I fix this?

Design question: one big NFS share or several smaller ones?
by Markus Schaufler 22 Feb '19

22 Feb '19

Hi all, I've got a design question: Are there any best practices regarding NFS datastores especially datastore sizing? Should I use one big NFS datastore and expand it on demand or should the size not exceed a certain limit and start with a new NFS datastore? Are there any other configuration considerations (NFS v3 or v4(.1) and mounting options)?
