Experience with Centos running off usb-stick(s)
Hi,
I'm trying to build a redundant duo of firewalls/routers/gateways and I'm
thinking about not putting any disks in them and instead using a usb-stick
raid-1 as storage.
Has anyone any experience with this? Since the machines will be running
pretty much only iptables, conntrackd and keepalived there is not going to
be a lot of disk activity going on and the plan is to do all the

Any alternatives for the horrible reposync
Hi,
I'm currently trying to mirror a couple of yum repositories and the only
tool that seems to be available for this is reposync.
Unfortunately reposync for some inexplicable reason seems to use the yum
config of the local system as a basis for its work which makes no sense
and creates all kinds of problems where cache directories and metadata
gets mixed up.
Are there any alternatives? Some

XFS : Taking the plunge
Hi All,
I have been trying out XFS given it is going to be the file system of
choice from upstream in el7. Starting with an Adaptec ASR71605 populated
with sixteen 4TB WD enterprise hard drives. The version of OS is 6.4
x86_64 and has 64G of RAM.
This next part was not well researched as I had a colleague bothering me
late on Xmas Eve that he needed 14 TB immediately to move data to from an

Hi,
today we ran into a strange problem: When performing a regular Windows

Previously the disk drive was using the Red Hat virtio drivers which
worked just fine but after the reboot after the update I just get a blue

VLAN issue
Do you need the whole configuration? On the switch end, we have the
relevant VLAN (VLAN 48) with the assigned IP address of 192.168.48.101 and
the range of ports (Gi1/0/1 - Gi1/0/8) assigned to that VLAN.
Seems - and acts - like a legitimate setup and works fine, except for this
particular instance.
Thanks.
Boris.

VLAN issue
Andrew and Dennis are spot on.
Their conclusions about your server being connected to an access port and
not a trunk port would be my conclusion as well.

RAID controller recommendations that are supported by RHEL/CentOS 8?
Hi,
I'm currently looking for a RAID controller with BBU/CacheVault and
while LSI MegaRaid controllers worked well in the past apparently they
are no longer supported in RHEL 8:
https://access.redhat.com/discussions/3722151
Does anybody have recommendations for for hardware controllers with
cache that should work in both CentOS 7 and 8 out of the box?

Kickstart and volume group with a dash in the name
Hi,
I'm trying to setup the provisioning of new OpenStack hypervisors with
cinder volumes on them. The problem is that kickstart doesn't allow
dashed in volume group names?
I tried this:
volgroup cinder-volumes --pesize=4096 pv.02
and this:
volgroup cinder--volumes --pesize=4096 pv.02
but in both cases I end up with a volume group named "cindervolumes" on
the system. Any

gluster map/reduce performance..
Hi, all,
i try to check the performance of Map/Reduce of Gluster File system.
Mapper side speed is quite good and it is sometimes faster than hadoop's map job.
But in the Reduce Side job is much slower than hadoop.
i analyze the result and i found the primary reason of slow speed is bad performance in Merging stage.
Would you have any suggestion for this issue

Allowing puppet to drop privileges for a manifest

Our environment consists of about 600 Redhat Enterprise Linux 3, 4, 5,

client running every 15 minutes from cron contacting a single cfservd
server. Additionally, our employees start their own cfengine and
