FC - Storage domain - space question + direct LUN (FC) SCSI passthrough a good idea ?
by morgan cox
Hi.
Couple of questions regarding Fibre Channel Storage ..
sing fibre channel storage domains - I know when you create storage domains you get 2 files on them 'OVF_STORE' which are less than 1 GB. I am using PREALLOCATED (RAW?) disks - if I were add a (preallocated) disk that fills the entire space would any issues occur ?
e.g the 2 OVF_STORE files are preallocated so I assume they will not grow (or need another one adding in future ?) - I have noticed 'Critical Space Action Blocker:' size - what happens if my disk covers the entire free space in a stoage domain (when using preallocated disks)
Also as a 2nd question : Rather than using a storage domain if I were to create disks using Direct LUN (Fibrechannel LUN) is it a bad idea to enable SCSI-PassThrough ? I ask as the simple FIO benchmarks I did showed improved performance.
Thanks

what happens at vdsm host certificate expiration
by Vinz Vinz
Hi Team,
we are using a custom certificate on the engine apache GUI /etc/pki/ovirt-engine/certs/apache.cer (following https://myhomelab.gr/linux/2020/01/20/replacing_ovirt_ssl.html) and it works fine. The certificate is valid for a very long period.
It seems the vdsm certificate (/etc/pki/vdsm/certs/vdsmcert.pem), on hosts side, has been renewed automatically at that time, but for only one year.
Now we wonder, what will happen when the vdsm certificate will expire? hosts will stop to be in the cluster? if yes what should we do to avoid that? is there a possibility to also apply our custom cert as vdsm cert?
This is for ovirt 4.4 running on rhel8
thx a lot in advance

Hosted-engine update error
by Jason Beard
Greetings! I was updating from ovirt 4.5.3 to ovirt 4.5.4 and my hosted engine has some package errors but the update seems to complete. The errors still exist with dnf. I feel like this is something that needs to be resolved but not sure.
When I query the rpmdb I do see ovirt-*-4.5.4.x packages are installed. When I ran the engine-setup it completed with no errors.
Errors:
# dnf update
Last metadata expiration check: 4:11:16 ago on Tue 20 Dec 2022 04:59:46 AM CST.

OVF_Store In Every Storage Doamin - Can We Remove?
by Matthew J Black
Hi All,
The Subject pretty much sums up the question I want to ask: There are two OVF_Store Disks created in all eight Storage Domains we have, making 16 total. This is cluttering up several of our views in the oVirt Admin Webpages. Is there anything stopping us from deleting some/all of these?
Cheers
