sernet Samba AD progress
by Robert Moskowitz 07 Sep '15

07 Sep '15

Just to let you know that I have made considerable progress with the Centos7-armv7 based server on a cubietruck. There is a LOT of services that are needed for a Samba AD: Time keeping - I am using Chrony DNS - Bind DHCP - dhcpd Samba/ldap/kerberos - sernet cups is installed, but I am going to remove it from the AD. Lots of steps to get all this working. One of the regulars on the Samba list gave me a script to handle the dyndns via dhcp. He had to change what he had to work with Centos. The point here is I am exercising more than just the Sernet code that Nicolas so kindly built for me. I also have cups installed, but I am going to change my smb.conf to remove printing support on the AD; the file server should do that, so that is one less service needed. Right now with it I am seeing: # free total used free shared buff/cache available Mem: 2062396 174948 1647400 24824 240048 1832628 Swap: 999420 0 999420 So it should run on a Cubieboard2 with only 1Gb memory.

So on my Cubieboard2 image I did yum groupinstall "GNOME Desktop" After some 800+ packages installed I rebooted. serial console is working and I am logged into it. But the monitor is showing just a grey screen with a mouse. No login.

System time
by Robert Moskowitz 03 Sep '15

03 Sep '15

How is system time set at boot? Is ntpdate run after the network is ready? How long does it retry waiting for the network to be available? I have seen a number of challenges becuase the system time is back at the epoch start as there is no battery rtc. And I wonder how many armv7 boards have a battery to maintain time across boots? Minimally, a process could right the time, in the proper format, to a file, say /etc/currenttime every 5 min and at shutdown. Then date can be run early in the boot process, piping this file in. It would not be perfect and does not help, much for new installs, but better than epoch start. Plus /etc/currenttime can be at least set to the image build date/time so not even firstboot will be at epoch start. Opinions?

Cubieboard2 Image
by miniNodes Info 02 Sep '15

02 Sep '15

Per the previous thread regarding Test Platforms, I have uploaded the RBF output here: http://www.mininodes.com/uploads/cubieboard2-centos-image.img.tar.gz This file was built with all default options, no modifications whatsoever were made. I simply wrote it to an SD Card, inserted in my Cubieboard2, and it booted right up. Hope this helps. -David

Bananapi / C7
by Nicolas 01 Sep '15

01 Sep '15

Hello I made some others tests for Bananapi and Centos image. Image generated with rbf is 4.3GB. I think we should shrink it to 4GB to allow people use 4GB cards. Maybe on a howto we can tell users to do : - install ntp (no clock on bananapi) - enable led activity - /sys/class/leds/bananapi\:green\:usr/trigger with on the following option : [none] usb-gadget usb-host cpu0 cpu1 mmc0 mmc0 is a good choice. - make eth0 dhcp by default I did a yum update, kernel armv7hl 4.2.0-0.rc2.git0.1.centos.el7 c7pass1 60 k kernel-core armv7hl 4.2.0-0.rc2.git0.1.centos.el7 c7pass1 17 M kernel-modules armv7hl 4.2.0-0.rc2.git0.1.centos.el7 c7pass1 11 M Updating: avahi armv7hl 0.6.31-14.el7 c7pass1 245 k avahi-autoipd armv7hl 0.6.31-14.el7 c7pass1 38 k avahi-libs armv7hl 0.6.31-14.el7 c7pass1 54 k kernel-tools armv7hl 4.2.0-0.rc2.git0.1.centos.el7 c7pass1 110 k kernel-tools-libs armv7hl 4.2.0-0.rc2.git0.1.centos.el7 c7pass1 65 k But I got the error : /usr/lib/kernel/install.d/51-dracut-rescue.install: line 59: /boot/loader/entries/5f978b1f46204461b2d19e876ea201d6-0-rescue.conf: No such file or directory warning: %posttrans(kernel-core-4.2.0-0.rc2.git0.1.centos.el7.armv7hl) scriptlet failed, exit status 1 Non-fatal POSTTRANS scriptlet failure in rpm package kernel-core-4.2.0-0.rc2.git0.1.centos.el7.armv7hl after reboot I'm still in 4.0.0-1.el7.armv7hl. Did someone want I try something on this image on bananapi? Thanks, Nicolas R.

Bind problems
by Robert Moskowitz 01 Sep '15

01 Sep '15

My new test nameserver on the C7-arm code cannot resolve: 0.centos.pool.ntp.org but has not trouble resolving: www.ietf.org My old nameserver on the C6 bind 9.8.2 resolves both with no problems. Both servers have identical conf and zone files (with the necessary SOA changes on the new server). Either: problems with the bind pre-alpha code things have changed between 9.8 and 9.9 such that things are breaking (I have disabled dnssec, for example). Ideas?

maintenance on the plague buildfarm
by Fabian Arrotin 01 Sep '15

01 Sep '15

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, As recently some users wanted to help, we got multiple new builds/repositories/targets on the armv7 build farm. I saw a potential impact on the local filesytem, and so a need to increase it (there was only 5GB+ free). Unfortunately, there is no possibility to "hot add" volumes on the scaleway nodes that we're currently using. So I have to power down the plague server itself, wait for the volume to be returned back to central store, and then add a bigger volume (through nbd) and restart it. I'm busy working on it right now, reason why the plague build farm will be unreachable during the maintenance.

No ethernet since trying to boot with selinux set to enforcing. I just booted with the F22 mSD card that worked just fine. No ethernet. I hope I don't have a dead board now. Help?
