[ovirt-users] Re: Resize partition cause oVirt installation failed

2020-08-04 Thread Lao Dh via Users
 Thank you Strahil and Gianluca,I am using oVirt Node 4.4.1.I just review the 
Document in the official website. It WARN not to change the format type. Some 
partitions must be set to LVM thin and Standard.Confirm changing the partition 
size has no problem.At last. I use the onboard AMD RaidXpert2 to form the 
RAID1. Although AMD said RaidXpert2 can support up to Red Hat 7.3 only.

If you use  custom setup,  you need to have the same partitions/LVs that  are 
used  by default .

Can you give a screenshot of the installer?

In my case it was indeed with the ovirt-node-ng iso, not tested in other way.In 
4.3 you were able, also with the iso of the ovirt-node-ng, to create different 
size partitions customizing the setup page (eg if you have gluster and want 
bigger /var than the default...).So in my opinion is a sort of regression...

2020-08-07 Thread Lao Dh via Users
 Hello Strahil,I follow the guide in "Installing oVirt as a self-hosted engine 
using the Cockpit web interface". Only 1 host and 1 SAS storage. Host and 
storage are direct attached. CentOS 8 was installed in host local disk.Only 1 
SAS cable connected. So I think shouldn't be the issue of Multipath.

 Update for all. The deployment finally detect the SAS collected storage. After 
manual compile the driver for the RAID control PCI card.Nir is correct. FC 
detect anything that is not "NFS, iSCSI". As this time it also detect a local 
connected SATA SSD.

Correct. FC in oVirt means actually not "iSCSI". Any device - including local
devices - that multipath expose, and is not iSCSI is considered as FC.

This is not officially supported and not documented anywhere. I learned
about it only we tried to deploy strict multipath blacklist allowing
only "iscsi"
or "fc" transport, and found that it broke users' setups with sas other esoteric
storage.

Since 4.4 is the last feature release, this will never change even if it is not
documented.

 Thanks all of you. The deployment did running and finished. It take 3+ hours 
to complete. Compare to previously only take less than an hour.Also, I found 
where to check the logs in cockpit. The log default filter to show only 
"Warning or above". I change it to show "Everything".

 I came across this in an environment where the proxy was very slow. The 
downloaded image for the appliance gets deleted every so often (and perhaps 
also via the cleanup script), so when it needs to be reloaded from the 
internet, it can take its time, because its quite large (>1GB).

Another source of trouble can be that PackageKit or simply another instance of 
yum/dnf is already running and that is blocking the download. Check with htop 
or similar.
