mixed hyperconverged?
by Philip Brown 16 Jul '20

16 Jul '20

I'm thinking of doing an SSD based hyperconverged setup (for 4.3), but am wondering about certain design issues. seems like the optimal number is 3 nodes for the glusterfs. but.. I want 5 host nodes, not 3 and I want the main storage for VMs to be separate iSCSI NAS boxes. Is it possible to have 3 nodes be the hyperconverged stuff.. but then add in 2 "regular" nodes, that dont store anything and arent part of the cluster? is it required to be part of the gluster cluster, to also be part of the ovirt cluster, if thats where the hosted-engine lives? or can I just have the hosted engine be switchable between the 3 nodes, and the other 2 be VM-only hosts? Any recommendations here? I dont what 5 way replication going on. Nor do I want to have to pay for large SSDs on all my host nodes. (Im planning to run them with the ovirt 3.4 node image) -- Philip Brown| Sr. Linux System Administrator | Medata, Inc. 5 Peters Canyon Rd Suite 250 Irvine CA 92606 Office 714.918.1310| Fax 714.918.1325 pbrown(a)medata.com| www.medata.com

Ovirt 4.4.1 Install failure at OVF_Store check
by farkey_2000＠yahoo.com 16 Jul '20

16 Jul '20

I am trying to freshly install oVirt 4.4.1 with HCI on CentOS 8.2. I am using the "hosted-engine --deploy" script and the installation fails at "Check the OVF Store" consistently. I did try to apply the fix loaded on Jenkins (https://jenkins.ovirt.org/job/ovirt-hosted-engine-setup_standard-check-patc…) which produced the same result. Any help is appreciated and I ma working to attached the install log. Thanks Andy

This vanishes completey with virtio-vga. using which client? remote-viewer? on which platform? qxl needs drivers, not sure if Arch has that…it should have, but for Windows you definitely need to install them.

What permission do I need to get API access
by miguel.garcia＠toshibagcs.com 15 Jul '20

15 Jul '20

We use LDAP authentication to login to ovirt cluster, actually, admin and another user account have to access API with no problem. My account does cannot access to API despite that had SuperUser privileges than those accounts that already access API. Every time I tried to access API I get next message: Error during SSO authentication access_denied: Cannot authenticate user 'diagsbuilder(a)ralntdom.rtptgcs.com': No valid profile found in credentials.. The account does exist and permissions to enter to portal vms What do need to do to grant access to API?

Backups are expected to disappear, they are temporary objects used to manage the backup process. Once the backup process was finished you can do nothing with the backup object, and you cannot fetch the same backup data again. > and I couldn't try incremental. > The fact that the backup disappeared should not prevent the next backup. After you create a backup, you need to poll backup status until the backup is ready. while backup.phase != BackupPhase.READY: time.sleep(1) backup = backup_service.get()# to_checkpoint_id will be used as If the backup does not end in ready state, it failed, and you cannot do anything with this backup. When the backup is ready, you can fetch the to_checkpoint_id created for this backup. checkpoint_id = backup.to_checkpoint_id At this point you need to persist the checkpoint id. This will be used to create the incremental backup.

Please check the event log to understand the failure. Eyal, can you show how to get the error from the backup using the SDK, in a way that can be used by a program? e.g. a public error code that can be used to decide on the next step, and an error message that can be used for displaying error to users of the backup application. This should be added to the backup_vm.py example. Nir

[OT] Major and minor numbers assigned to /dev/vdx virtio devices
by Gianluca Cecchi 14 Jul '20

14 Jul '20

Hello, isn't there an official major/minor numbering scheme for virtio disks? Sometimes I see 251 major or 252 or so... what is the udev assignment logic? Reading here: https://www.kernel.org/doc/Documentation/admin-guide/devices.txt 240-254 block LOCAL/EXPERIMENTAL USE Allocated for local/experimental use. For devices not assigned official numbers, these ranges should be used in order to avoid conflicting with future assignments. it seems they are in the range of experimental ones, while for example Xen /dev/xvdx devices have their own static assignment (202 major) Thanks, Gianluca
