Can I Move a Fiber Channel Domain between different environments?
by Jacob Green 13 Nov '18

13 Nov '18

We have two Ovirt environments, our existing environment is Ovirt 4.1 And we want to migrate to our 4.2 environment, we chose this path because upgrading had a lot of issues for us, also we are migrating our cluster environment to a new IP scheme. So this made the most sense to us. The question we have now is can we simply move an existing Fiber Channel domain from our Ovirt 4.1 environment to our 4.2 environment. I see information here that suggests we can, https://ovirt.org/documentation/admin-guide/chap-Storage/ however there is information further down in the document that seems conflicting or I am confused, I am willing to accept that. *Near the top of the page I linked it says the following* "Note:The export storage domain is deprecated. Storage data domains can be unattached from a data center and imported to another data center in the same environment, or in a different environment. Virtual machines, floating virtual disk images, and templates can then be uploaded from the imported storage domain to the attached data center. SeeImporting Existing Storage Domains <https://ovirt.org/documentation/admin-guide/chap-Storage/sect-Importing_Exi…>for information on importing storage domains." **Ok cool so I should be able to import the storage domain into a new environment? According to that information it would seem so.* * *However further down it says the following,* "Reusing LUNs LUNs cannot be reused, as is, to create a storage domain or virtual disk. If you try to reuse the LUNs, the Administration Portal displays the following error message:" So I do not want to make a mistake, and remove my storage domain from my original ovirt environment just to find I cannot re add it to the new ovirt environment, and if I do that will I be able to import the VMs? Thank you for any guidance on this topic, It would be much appreciated. I guess the TLDR would be is the part pasted below of the linked documentation accurate for fiber channel? "Data Importing an existing data storage domain allows you to access all of the virtual machines and templates that the data storage domain contains. After you import the storage domain, you must manually import virtual machines, floating disk images, and templates into the destination data center. The process for importing the virtual machines and templates that a data storage domain contains is similar to that for an export storage domain. However, because data storage domains contain all the virtual machines and templates in a given data center, importing data storage domains is recommended for data recovery or large-scale migration of virtual machines between data centers or environments. Important: You can import existing data storage domains that were attached to data centers with a compatibility level of 3.5 or higher." Please forgive my confusion. -- Jacob Green Systems Admin American Alloy Steel 713-300-5690

Networking - How to pass all vlan (trunk) to a guest VM?
by Jonathan Greg 13 Nov '18

13 Nov '18

Hi, I didn't find the documentation about it... How I can pass all the vlan (trunk) to a guest VM (without SR-IOV)? My switch is configured to trunk all vlans. I do have configured a logical network with the "Enable VLAN tagging" box uncheck and assign it to a VM. My understanding with this setting is that tagged and untagged packet should be forwarded to the VM guest. Unfortunately it doesn't work at all, if I run a tcpdump on the VM nic attached to this logical network, I don't see anything... I would really like to run a virtual router or firewall on my setup without having to shutdown my VM and having attach a new vnic each time I want to add a new vlan. Any idea? Jonathan

Re: storage healing question

Hi, Can you restart the self-heal daemon by doing a `gluster volume start bgl-vms-gfs force` and then launch the heal again? If you are seeing different entries and counts each time you run heal info, there is likely a network issue (disconnect) between the (gluster fuse?) mount and the bricks of the volume leading to pending heals. Also, there was a bug in arbiter volumes[1] that got fixed in glusterfs 3.12.15. It can cause VMs to pause when you reboot the arbiter node, so it is recommended to upgrade to this gluster version.

New disks cloned from template get wrong quota-id, when quota is disabled on DC
by Florian Schmid 12 Nov '18

12 Nov '18

Hi, we have recently upgraded our ovirt environment from 4.1.6 to 4.1.9 and then to 4.2.5. I don't know exactly when this issue was happened the first time, because on the affected DCs, we haven't created new VMs for some time ago. To our setup: We have several DCs configured and only the former default one has quota enabled. We have separate templates for each DC and they haven't been cloned or anything else from a template in default DC When I now create a VM on DC from a template (disks are cloned), where quota is not enabled, the new disks are getting quotas assigned, which are not available in that DC! The template disks all have the correct quota ID assigned! Example from engine DB: select * from image_storage_domain_map where storage_domain_id = '73caedd0-6ef3-46e0-a705-fe268f04f9cc'; -> ... a50b46ce-e350-40a4-8f00-968529777446 | 73caedd0-6ef3-46e0-a705-fe268f04f9cc | 58ab004a-0315-00d0-02b8-00000000011d | 4a7a0fea-9bc4-4c3a-b3f4-0e8444641ea3 1cd8f9d9-e2b5-4dec-aa3b-ade2612ed3e7 | 73caedd0-6ef3-46e0-a705-fe268f04f9cc | 58ab004a-009a-00ea-031c-000000000182 | 4a7a0fea-9bc4-4c3a-b3f4-0e8444641ea3 2f982856-7afa-4f18-a676-fe2cc44b14d6 | 73caedd0-6ef3-46e0-a705-fe268f04f9cc | 58ab004a-009a-00ea-031c-000000000182 | 4a7a0fea-9bc4-4c3a-b3f4-0e8444641ea3 ... -> ll ./6d979004-cb4c-468e-b89a-a292407abafb/ insgesamt 1420 -rw-rw----. 1 vdsm kvm 1073741824 Nov 6 15:46 a50b46ce-e350-40a4-8f00-968529777446 -rw-rw----. 1 vdsm kvm 1048576 Nov 6 15:46 a50b46ce-e350-40a4-8f00-968529777446.lease -rw-r--r--. 1 vdsm kvm 271 Nov 6 15:46 a50b46ce-e350-40a4-8f00-968529777446.meta As you see, the disk a50b46ce-e350-40a4-8f00-968529777446 was created some minutes ago, but it has a different default quota ID assigned as the other disks above. 58ab004a-0315-00d0-02b8-00000000011d instead of 58ab004a-009a-00ea-031c-000000000182 select * from quota; id | storage_pool_id | quota_name | description | _create_date | _update_date | threshold_cluster_percent age | threshold_storage_percentage | grace_cluster_percentage | grace_storage_percentage | is_default --------------------------------------+--------------------------------------+------------+-------------------------+-------------------------------+-------------------------------+-------------------------- ----+------------------------------+--------------------------+--------------------------+------------ 58ab004a-0315-00d0-02b8-00000000011d | 00000001-0001-0001-0001-000000000089 | Default | Default unlimited quota | 2017-02-20 14:42:18.967236+00 | | 80 | 80 | 20 | 20 | t 58ab004a-009a-00ea-031c-000000000182 | 5507b0a6-9170-4f42-90a7-80d22d4238c6 | Default | Default unlimited quota | 2017-02-20 14:42:18.967236+00 | | 80 | 80 | 20 | 20 | t As you see here, both quota IDs are default IDs and therefore can't be on the same DC or storage domain. As soon I enable quota on that DC, new disks created by VM creation via template, will get the correct quota ID. The problem with wrong IDs is, that you can't edit the disks anymore! I can repeat that error every time and I can give all the information you need to debug this. Pleas inform me, what data do you need... Best Regards Florian

storage healing question
by Dev Ops 12 Nov '18

12 Nov '18

The switches above our environment had some VPC issues and the port channels went offline. The ports that had issues belonged to 2 of the gfs nodes in our environment. We have 3 storage nodes total with the 3rd being the arbiter. I wound up rebooting the first 2 nodes and everything came back happy. After a few hours I noticed that the storage was up but complaining about being out of sync and needing healing. Within the hour I noticed a VM had paused itself due to storage issues. This is a small environment, for now, with only 30 VM's. I am new to Ovirt so this is uncharted territory for me. I am tailing some logs and things look sort of normal and google is sending me down a wormhole. If I run "gluster volume heal cps-vms-gfs info" this number seems to be changing pretty regularly. Logs are showing lots of entries like this: [2018-11-08 21:55:05.996675] I [MSGID: 114047] [client-handshake.c:1242:client_setvolume_cbk] 0-cps-vms-gfs-client-1: Server and Client lk-version numbers are not same, reopening the fds [2018-11-08 21:55:05.997693] I [MSGID: 108002] [afr-common.c:5312:afr_notify] 0-cps-vms-gfs-replicate-0: Client-quorum is met [2018-11-08 21:55:05.997717] I [MSGID: 114035] [client-handshake.c:202:client_set_lk_version_cbk] 0-cps-vms-gfs-client-1: Server lk version = 1 I guess I am curious what else should I be looking for? Is this just taking forever to heal? Is there something else I can run or I should do to verify things are actually getting better? I ran an actual heal command and it cleared everything for a few seconds and then the entries started to populate again when I did the info command.

Network/Storage design

Hi, I am new to oVirt and trying to deploy a cluster to see whether we can move from VMWare to oVirt, but my first stopper is how to do a proper design for the infrastructure, how many networks do I need?, I have 2x10Gb SFP+ and 4x1Gb ethernet. For storage we have NFS coming from Netapp and ceph. Could someone point me in the right direction? Thanks.
