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

[root@oeng rootfs]#

 

 

 

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 ?

 

Thanks!
