Hi, everyone:
I meet a question when I update ovirt from 4.4.3 to 4.4.4.
First, I update my ovirt engine vm using yum update, the using hosted-engine reconfigure system.
But, then I found that others hosts (including engine vm’s hosts and other KVM hosts) show need update. Then I checked the yum update info, I found these hosts needs to download and install this rpm file:
[root@host1 ~]# yum update

Is this ok [y/N]: n
So, I just download the rpm file and unpack it, I found that it includes two files:
[root@oeng image]# ll
total 838416
-rw-r--r--. 1 root root 858533888 Jan 15 11:23 ovirt-node-ng-image-update-4.4.4-1.el8.squashfs.img
-rw-r--r--. 1 root root 3962 Jan 15 11:23 product.img
Then, I unpack the squashfs.img files, and mount the file, I found it’s a linux rootfs:
[root@oeng rootfs]# ll

But the product.img file cannot be mounted,it raese error:
[root@oeng image]# mount -o loop ./product.img /mnt/product/
mount: /mnt/product: wrong fs type, bad option, bad superblock on /dev/loop1, missing codepage or helper program, or other error.
I feel that this rpm is for making engine vm. But I have updated my engine vm, then should I continue using yum update to update my hosts ?
The product.img rpm is used for ovirt-node iso.
You can update the hosts via UI or using yum update as you described.
Thanks!
