[ovirt-users] Re: how to remove host (phisical damaged) on ovirt web panel ??
Hi Tommy, I am not sure about your environment state, but you have an option to confirm that the host 'has bee rebooted'. It should eventually set the VMs as down in your case and set the host in the state that will allow you to remove it. Please see the attached screenshot.

[ovirt-users] Re: [BULK] Re: very very bad iscsi performance
Thank you for the analysis. I have some further comments: First off, filebench pre-writes the files before doing oltp benchmarks, so I dont think the thin provisioning is at play here. I will double check this, but if you dont hear otherwise, please presume that is the case :) Secondly, I am surprised at your recommendation to use virtio instead of virtio-scsi. since the writeup for virtio-scsi claims it has equivalent performance in general, and adds better scaling https://www.ovirt.org/develop/release-management/features/storage/virtio-scsi.html As far as your suggestion for using multiple disks for scaling higher: We are using an SSD. Isnt the whole advantage of using SSD drives, that you can get the IOP/s performance of 10 drives, out of a single drive? We certainly get that using it natively, outside of a VM. SO it would be nice to see performance approaching that within an ovirt VM. - Original Message - From: "Nir Soffer" To: "Philip Brown" Cc: "users" , "qemu-block" , "Stefan Hajnoczi" , "Paolo Bonzini" , "Sergio Lopez Pascual" , "Mordechai Lehrer" , "Kevin Wolf" Sent: Tuesday, July 21, 2020 4:23:36 AM Subject: [BULK] Re: [ovirt-users] very very bad iscsi performance On Tue, Jul 21, 2020 at 2:20 AM Philip Brown wrote: > > yes I am testing small writes.

Known issue with such a disk is possible pausing of the VM when the disk becomes full, if oVirt cannot extend the underlying logical volume fast enough. It can be mitigated by using larger chunks in vdsm. We recommend these settings if you are going to use VMs with heavy I/O with thin disks: # cat /etc/vdsm/vdsm.conf.d/99-local.conf [irs] # Together with volume_utilization_chunk_mb, set the minimal free # space before a thin provisioned block volume is extended. Use lower # values to extend earlier. # default value: # volume_utilization_percent = 50 volume_utilization_percent = 25 # Size of extension chunk in megabytes, and together with # volume_utilization_percent, set the free space limit. Use higher # values to extend in bigger chunks. # default value: # volume_utilization_chunk_mb = 1024 volume_utilization_chunk_mb = 4096 With this configuration, when free space on the disk is 1 GiB, oVirt will extend the disk by 4 GiB. So your disk may be up to 5 GiB larger than the used space, but if the VM is writing data very fast, the chance of pausing is reduced. If you want to reduce the chance of pausing your database in the most busy times to zero, using a preallocated disk is the way. In oVirt 4.4. you can check this option when creating a disk: [x] Enable Incremental Backup With: Allocation Policy: [Preallocated] You will get a preallocated disk in the specified size, using qcow2 format. This gives you both the option to use incremental backup, faster disk operations in oVirt (since qemu-img does not need to read the entire disk), and avoids the pausing issue. It may also defeat thin provisioning, but if your backend storage supports thin provisioning anyway it does not matter. To get best performance for database use case preallocated volume should be better. Please try to benchmark: - raw preallocated disk - using virtio instead of virtio-scsi If your database can use multiple disks, you may get better performance by adding multiple disks and use one
[ovirt-users] Re: Upgrade from 4.3 to 4.4 fails with db or user ovirt_engine_history already exists
Hi Didi, I don't know. We are were running the same oVirt instance since 2017 and updated it a lot of times, including solving some bugs/problems during the years. The user was set on the 'vm_device_history'-table and the 'disk_vm_device_history_seq' sequence. Maybe we did it ourselves, but I couldn't find anything about it in our logs. Since we are new here: After this problem, we ran into some other problems. Do you want me to post an article about it, including the steps we have taken to solve them? We got stuck on the latest problem, and we stopped our upgrade to 4.4 for now, but it could be related to the other thread about Storage Domains. Running the upgrade and accessing the 4.4 GUI before continuing (you can set this option at the beginning), we are unable to update any OVF Disks (automatically or forced), and the active SPM host keeps resetting (also after changing it to the new 4.4 host). It does not matter if we try to update an existing SD, the old hosted engine domain, or add a new one (NFS or Gluster). When we ignore the problem, the installation fails when it checks the health of the new hosted engine domain. Restarting the old HE again, and the problem is (luckily) solved and not permanent - so I guess it is a HE 4.4 specific problem. I analyzed the logs but couldn't find anything that made sense (on the host, HE VM, or another 4.3 host running SPM). The error(s): - Failed to update VMs/Templates OVF data for storage domain XX in Data Center Default - Failed to update OVF disks xGUIDx, xGUIDx, OVF data isn't updated on those OVF stores (Data Center Default, Storage domain XX) The error disappeared on most SDs (except the old HE domain, or any new added one) when we force an OVF update via the 4.3 GUI (before starting the upgrade). The old HE VM was turned off (and the platform set to global maintenance) before we started the upgrade. ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/5EQQTY6QTDRP4RHGFSEM5LS46ZQ4UGO4/

Thanks Strahil and Sandro for your replies and sorry for the delay. @strahil [main] gpgcheck=1 installonly_limit=3 clean_requirements_on_remove=True best=True skip_if_unavailable=False Which it just is the original dnf.conf. To this, we'd apply the proxy settings written above the question. But we reach the SSL error. @sandro Unfortunately we can not use the smart proxy. We cannot install applications. Katello rpm as an example. We have our Foreman in place and we can download the 'katello-ca-consumer-latest.noarch.rpm' using CURL. But, when trying to install it, 'yum localinstall katello-ca-consumer-latest.noarch.rpm', it requires 'subscription-manager' as dependency package, which is not installed/included in CentOS8/RHEL8 and fails. Foreman is for the moment excluded. It could be interesting to fix the SSL/proxy issue, we haven't yet found how to fix it. Maybe you could address us, please?

Do you have NICs that support iSCSI -I guess you can use hardware offloading? MTU size ? Lattency is usually the killer of any performance, what is your round-trip time ?

So you can ssh into the engine VM with that ip and go into /var/log/ovirt-engine/host-deploy/ directory to check logs btw: why 4.3.8 and not 4.3.10?

[ovirt-users]回复: Re: iSCSI multipath with separate subnets... still not possible in 4.4.x?
I saw through their administration panels that in Storage -> iScsi section there are also two targets with different subnets and the command on the host multipath -ll also showed the normal operation of the two targets. That's mean that: multipath can not create a logic LUN which using two subnet as it's concurrent path , and the LUN can not avoid failing of It's only IP path, is it ?? -邮件原件- 发件人: users-boun...@ovirt.org 代表 Patrick Lomakin 发送时间: 2020年7月20日 16:04 收件人: users@ovirt.org 主题: [ovirt-users] Re: iSCSI multipath with separate subnets... still not possible in 4.4.x? I don't quite understand what multipath is, but when I deployed it in my iSCSI repository, only one ip address is specified when installing hosted-engine. However, in order to specify the second subnet, I went to my host portal where I was deploying the engine and added the second subnet in the Storage -> iSCSi targets section. It should be noted that the storage is connected to hosts directly. However, after that when adding subsequent hosts through the engine I saw through their administration panels that in Storage -> iScsi section there are also two targets with different subnets and the command on the host multipath -ll also showed the normal operation of the two targets. I hope this helps you in any way. ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/6XUZLGQVE2DNFD5VYMRN3F6RKELYWK5L/ ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/AFIGPX7ZMWIUHEUFVY5635SAY6WLF5MK/
