Re: OVirt Gluster Fail

Hi Andrea, The cluster volumes might have sharding enabled and thus files larger than shard size can be recovered only via cluster. You can try to restart gluster on all nodes and force heal: 1. Kill gluster processes: systemctl stop glusterd /usr/share/glusterfs/scripts/stop-all-gluster-processes.sh 2. Start gluster: systemctl start glusterd 3. Force heal: for i in $(gluster volume list); do gluster volume heal $i full ; done sleep 300 for i in $(gluster volume list); do gluster volume heal $i info summary ; done Best Regards, Strahil NikolovOn Mar 23, 2019 13:51, commramius(a)tiscali.it wrote: > > During maintenance of a machine the hosted engine crashed. > At that point there was no more chance of managing anything. > > The VMs have paused, and were no longer manageable. > I restarted the machine, but one point all the bricks were no longer reachable. > > Now I am in a situation where the engine support is no longer loaded. > > The gluster sees the peers connected and the services turned on for the various bricks, but fails to heal the messages that I find for each machine are the following > > # gluster volume heal engine info > Brick 192.170.254.3:/bricks/engine/brick > > . > . > . > > Status: Connected Number of entries: 190 > > Brick 192.170.254.4:/bricks/engine/brick > Status: Il socket di destinazione non è connesso > Number of entries: - > > Brick 192.170.254.6:/bricks/engine/brick > Status: Il socket di destinazione non è connesso > Number of entries: - > > this for all the bricks (some have no heal to do because the machines inside were turned off). > > In practice all the bricks see only localhost as connected. > > How can I restore the machines? > Is there a way to read data from the physical machine and export it so that it can be reused? > Unfortunately we need to access that data. > > Someone can help me. > > Thanks Andrea > _______________________________________________ > Users mailing list -- users(a)ovirt.org > To unsubscribe send an email to users-leave(a)ovirt.org > Privacy Statement: https://www.ovirt.org/site/privacy-policy/ > oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ > List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/EOIY7ZU4GOEMR…

How to create a template from VM Portal
by Wood Peter 26 Mar '19

26 Mar '19

Hi, How do I create a template from a VM in "VM Portal"? I'm using version 4.2.8.2 and I don't see the option to convert a VM to a template anywhere. The documentation refers to the Administration Portal interface. Is it possible to create a template from the "VM Portal" or one must login to "Administration Portal"? Any help would be appreciated. Thank you, -- Peter

API POST ovf file instead of libvirt KVM regular xml
by Nathanaël Blanchet 25 Mar '19

25 Mar '19

Hi all, I've got a ovf file where I need to reuse nic defintions. I want to post them to the REST API, but in API documentation, I'm only able to find examples with libvirt definition. So my question is : does ovf file are supported to be directly posted or is there a way to convert ovf file to libvirtxml so as to post them to the API? Thank you.

Gluster event logging
by Ron Jerome 25 Mar '19

25 Mar '19

I'm running oVirt 4.3.2, and just upgraded gluster to 5.5. I see that the gluster event daemon now works, however the events are not being processed by the ovirt engine. On the engine side I'm seeing: "engine.log:2019-03-25 17:14:04,707-04 ERROR [org.ovirt.engine.core.services.GlusterEventsWebHookServlet] (default task-198) [] Error processing event data" in the engine log. On the gluster servers in event.log, I'm seeing: "[2019-03-25 17:14:04,704] WARNING [utils - 272:publish_to_webhook] - Event push failed to URL: http://ovirt-engine:80/ovirt-engine/services/glusterevents, Event: {"event": "CLIENT_CONNECT", "message": {"brick_path": "/gluster_bricks/ISO/ISO", "client_identifier": "10.10.15.12:49120", "client_uid": "CTX_ID:d988b64d-2996-44c4-88ed-ee768c9e0c21-GRAPH_ID:0-PID:43711-HOST:ovirt2-PC_NAME:ISO-client-2-RECON_NO:-0", "server_identifier": "10.10.15.12:49155", "subdir_mount": "(null)"}, "nodeid": "9a6ea54e-c692-45bd-889b-ed20c6fb1145", "ts": 1553548444}, Status Code: 500" How can I determine why these events are not getting processed? Thanks,

Hosted Engine Storage migration
by joel+ovirt＠robisons.us 25 Mar '19

25 Mar '19

Hello listmembers! I'm in search of some steps to use to migrate my Hosted-Engine from one NFS storage domain to another different NFS storage domain. One of the possible ways to accomplish this task may already be a feature with oVirt 4.1, I'm using 4.2 https://lists.ovirt.org/pipermail/users/2017-January/078739.html (New feature in 4.1?) Will someone elaborate the steps to use this new feature and how I could use it to accomplish this task? the bug link in the email linked above has a comment (https://bugzilla.redhat.com/show_bug.cgi?id=1409112#c12) - does this mean I need to redeploy the hosted-engine? I'm not able to follow as I'm new to oVirt and still learning the ins and outs and design if I'm on the wrong path here please correct me. Thank you, -Joel

Hosts not coming back into oVirt
by Arif Ali 25 Mar '19

25 Mar '19

Hi all, Recently deployed oVirt version 4.3.1 It's in a self-hosted engine environment Used the steps via cockpit to install the engine, and was able to add the rest of the oVirt nodes without any specific problems We tested the HA of the hosted-engine without a problem, and then at one point of turn off the machine that was hosting the engine, to mimic failure to see how it goes; the vm was able to move over successfully, but some of the oVirt started to go into Unassigned. From a total of 6 oVirt hosts, I have 4 of them in this state. Clicking on the host, I see the following message in the events. I can get to the hosts via the engine, and ping the machine, so not sure what it's doing that it's no longer working VDSM <snip> command Get Host Capabilities failed: Message timeout which can be caused by communication issues Mind you, I have been trying to resolve this issue since Monday, and have tried various things, like rebooting and re-installing the oVirt hosts, without having much luck So any assistance on this would be grateful, maybe I've missed something really simple, and I am overlooking it -- regards, Arif Ali
