Hi All,
Recently I had to update a host that uses raid1 for /boot and /boot/efi and I
noticed that my resync service is failing with "mdadm: --update=resync not
understood for 1.x metadata”.
Does anyone know why 'mdadm-4.2-rc2.el8.x86_64.rpm’ supports it but
'mdadm-4.2-13.el8.x86_64’ not ?
Or just try:echo PASS | your_script.sh
If it needs to answer multie prompts:echo -e 'USER\nPASS' | your_script.sh

XFS is suitable for parallel workload, so I would pick ext4 for this case.
Here is a quote from https://access.redhat.com/articles/3129891 :
Another way to characterize this is that the Ext4 file system variants tend to
perform better on systems that have limited I/O capability. Ext3 and Ext4
I have never played with Infinibad, but I think that those cards most

Have you explored in that direction and test with checksum in ofloaded

If you decide to go with Stream, you will need to test carefully each
version and use some kind of repository management - as there will be
no older
Verify that:
1. Autofs is not running
2. Systemd has created '.mount' and '.automount' units

3. Verify that there are no errors in local-fs.target

and the peculiar thing is it STILL does not automount. and yes, I did do

do I need to reboot (or something simpler, maybe) to fully disable the

If you picked the systemd automounter as an option, you will have to

If anyone is considering to fork CentOS 8 (I'm not talking about that

Otherwise I will switch to openSUSE Leap. At least they are not pushing

Have you tried with Network Manager , after all this is the thing that manages
all networks:
[root@system ~]# nmcli connection add con-name dummy0 ifname dummy0 type dummy
Connection 'dummy0' (9fdd74fa-c143-4991-9bac-0e542704ac89) successfully added.

I had similar issue on 7.6 - the LVM timeouts were too short and it was timing
out as we had a lot of multipath devices. Once those were up , you could just
continue.

Hi Alessandro,
Compared to Microsoft , both RH and SuSE are awesome.
You always need a patch management strategy with locked repos
(spacewalk/pulp) which can be tested on less important systems, prior
deployment on Prod.
Keep in mind that Secureboot is hard to deploy in Virtual

Don't forget that EL 7 (non-UEFI systems) & 8 support booting from LVM snapshot
(a.k.a BOOM Boot Manager) , so revert is 2 steps away:
- boot from the snapshot (grub menu)
- revert from the lvm snapshot
- reboot and wait for the revert to complete

I got 5 CentOS 8.1 VMs minimal install.
When I did the update I got 1 that had dnf issues and corrupted rpm DB and
another 1 that didn't boot.
Restore from snapshot and again update -> no issues. For me it looks more like
a random issue.
