Solarflare SFC9000 direct connection

hi guys

I wonder if any of you might be using SFN6122F-R7 SFP+ (SFC9000, same
firmware everywhere, Centos 7.5 too.

I'm trying poor man's setup to get the servers onto 10GbE network.

Setup is such that three Dell R815 are connected to each other, each has
one Solarflare(SFP ports) and each Solarflare is set as net-team(both
ports on a card are net-team device) with runner in broadcast mode. And
it all seems to work, they ping each other, iperf okey.

The problem, big problem is that when traffic start to flow between all
three servers simultaneously, with rsync for example, then!!


hi guys,

shellinabox, do you use it?

I in pretty vanilla setup get selinux denials and cannot login.

Selinux says:

#============= unconfined_service_t ==============

#!!!! The file '/usr/bin/bash' is mislabeled on your system.
#!!!! Fix with $ restorecon -R -v /usr/bin/bash
allow unconfined_service_t unconfined_t:process transition;

but that does not seem right to me, to allow such a transition, right?

many thanks, L.

multipath recipe for an enclosure ?

hi guys,

In hope that some experts roam around I post this one question - how do
you multipath disks(all disks) that sit in one specific SAS enclosure?
Blacklist everything else.

And I'm hoping for something like "globing", so you do not want to go
through it on by single disk/wwin basis.

some experts?(or maybe even not, it could be that I do not get it)

many thanks, L.

CentOS-6.9 Bind-9.8.2 error messages

I am encountering messages similar to this in the system logfile:

Jun 20 13:38:18 inet03 named[3720]: malformed transaction:
last serial 103538 != transaction first serial 103361

I have no idea what this means, what caused it, nor how to fix it.
Any suggestions relevant to any of the above are most welcome.

About the membership issue

Concerning the disabled membership (yesterday). Is there anything that I should do?
Visiting the "re-enable" link shows only a plain site with meta information about
the list but without any feedback like "membership enabled". Albeit some postings are
coming in again now (with "normalized" sender address < ... at centos dot org>). Seems
the work to resolve this issue is in progress ...
