have udev to ignore/hide a scsi disk - but how?
by lejeczek 30 Mar '17

30 Mar '17

hi everyone I've been playing and trying to tell udev to ignore and not create symlinks in /dev but I fail. Hoping this is the one: ENV{ID_SERIAL}== I've tried: ENV{SYSTEMD_READY}:="0" OPTIONS+="last_rule" even ENV{UDISKS_IGNORE}="1" but udev tests would still show: ACTION=add and symlinks created. Would share an advice? many thanks, L.

Python 3.x on Centos 7
by Matt 29 Mar '17

29 Mar '17

Is there a way to install Python 3.x on Centos 7.x without breaking anything that depends on an older version of Python? This server is a minimal Centos 7 install that primarily runs a simple LAMP setup.

If you enable the CR repo on your 6.x machine I believe you'll see these updates, and can install them if you want to check things out. My experience is that there will likely be a few updates from the CR when the production set is released. If you go to: http://mirror.centos.org/centos/6.8/cr/<i386|x86_64>/Packages/ you'll see that there are packages for both 32- and 64-bit, so you should be getting 32-bit updates that will take you up to 6.9.

Mixed bonding and vlan on plain adapter possible?
by Gianluca Cecchi 29 Mar '17

29 Mar '17

Hello, I have a CentOS 7.3 + updates server where my configuration arises from the need to connect via iSCSI to a Dell PS Series storage array and Dell not supporting bonding. So that I need to use 2 nics on the same vlan to connect to iSCSI portal IP and then use multipath. Also, the iSCSI lan is on a dedicated vlan I have only these 2 x 10Gbit adapters and I also need to put other vlans on them through bonding. I plan to use active-backup as bonding mode. My first tests were only with iSCSI in place to verify connection is ok I followed these Dell guidelines, for both multipath and sysctl configs for network adapters: http://en.community.dell.com/techcenter/extras/m/white_papers/20442422 iSCSI vlan is 100 so that the configured devices are p1p1.100 and p1p2.100 and my sysctl config is: net.ipv4.conf.p1p1/100.arp_announce=2 net.ipv4.conf.p1p2/100.arp_announce=2 net.ipv4.conf.p1p1/100.arp_ignore=1 net.ipv4.conf.p1p2/100.arp_ignore=1 # net.ipv4.conf.p1p1/100.rp_filter=2 net.ipv4.conf.p1p2/100.rp_filter=2 So far so good and my lun is viewed this way through multipath [root@ov300 etc]# multipath -l 364817197b5dfd0e5538d959702249b1c dm-3 EQLOGIC ,100E-00 size=1.0T features='0' hwhandler='0' wp=rw `-+- policy='round-robin 0' prio=0 status=active |- 7:0:0:0 sde 8:64 active undef running `- 8:0:0:0 sdf 8:80 active undef running I tried a test workload and both paths are used in a balanced way. Now I temporarily stop the iSCSI layer and ifdown the p1p1.100 and p1p2.100 devices and put in place bonding on plain p1p1 and p1p2 interfaces and then vlans over it and bridges (they are for VMs) [root@ov300 ~]# cat /proc/net/bonding/bond1 Ethernet Channel Bonding Driver: v3.7.1 (April 27, 2011) Bonding Mode: fault-tolerance (active-backup) Primary Slave: None Currently Active Slave: p1p1 MII Status: up MII Polling Interval (ms): 100 Up Delay (ms): 0 Down Delay (ms): 0 Slave Interface: p1p1 MII Status: up Speed: 10000 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: a0:36:9f:2e:4d:80 Slave queue ID: 0 Slave Interface: p1p2 MII Status: up Speed: 10000 Mbps Duplex: full Link Failure Count: 1 Permanent HW addr: a0:36:9f:2e:4d:82 Slave queue ID: 0 [root@ov300 ~]# - ifcfg-bond1.65 DEVICE=bond1.65 VLAN=yes BRIDGE=vlan65 ONBOOT=yes MTU=1500 DEFROUTE=no NM_CONTROLLED=no IPV6INIT=no - ifcfg-vlan65 DEVICE=vlan65 TYPE=Bridge DELAY=0 STP=off ONBOOT=yes MTU=1500 DEFROUTE=no NM_CONTROLLED=no IPV6INIT=no [root@ov300 network-scripts]# brctl show vlan65 bridge name bridge id STP enabled interfaces vlan65 8000.a0369f2e4d80 no bond1.65 [root@ov300 network-scripts]# The same for vlans 162, while for vlan 187 I only have the bond1.187 without a bridge on top of it At the end I try to re-start the iSCSI components, but it seems now I have iSCSI connection interrupted and not stable.

Nodejs010 Packages giving unresolved dependency error when building the nodejs packages
by Maheshwari, Shagun 29 Mar '17

29 Mar '17

Hi, I am trying to built an ISO with nodejs010 packages but when I run the command "repoclosure -a x86_64 -r <local-repository-name>" to check its further dependencies, it is giving unresolved dependencies error. Example: package: nodejs010-node-gyp-3.2.0-2.el7.centos.noarch from Harman (it's a local repo name) unresolved deps: npm(minimatch) < 0:4 npm(minimatch) >= 0:3 nodejs(engine) >= 0:0.8.0 In ISO we have nodejs010-nodejs-minimatch-3.0.2-1.el7 but it is giving error that npm(minimatch) < 0.4 or npm(minimatch) >= 0:3 and on mirror.centos.org latest version of this package is 3.0.2-1. It was an example, there are many errors like this. So, Please find the attached nodejs-unresolved-dep-erre.log file. I have also attached the list of nodejs's RPMs which I want to include in my ISO. Steps to reproduce this issue: 1. Built all nodejs packages using mock Mock -r centos-7-x86_64 rebuild -define 'scl nodejs010' nodejs010-x.x.x.src.rpm 2. Copy all nodejs rpms in a folder 3. Make a local repository in /etc/yum.repos.d/ folder e.g. 1. cd /etc/yum.repos.d/ 2. mkdir dep.repo 3. copy following lines in dep.repo file: [harman] name=harman baseurl=file:///path of the folder where you have copied your nodejs rpms/ enabled=1 4. Run the following command in that folder where you have copied your rpms: createrepo . 5. Then run repoclosure -a x86_64 -r harman But when I download all nodejs rpms from http://mirror.centos.org/centos-7/7.3.1611/sclo/x86_64/rh/nodejs010/ site and repeat the same steps then it is not giving any unresolved dependency errors. Why it is happening ? or There is any problem with our rpm building process ? Please response and help. Regards, Shagun Maheshwari

mirror for debug_info repo
by jsl6uy js16uy 28 Mar '17

28 Mar '17

Hello all hope all is well. We pull down via rsync from a Centos mirror for general updates/os/etc. I don't see a mirror for debuginfo.centos.org::centos-debuginfo well debuginfo.centos.org. The banner for the site states you should only use this site if you plan to be a public mirror. I have not checked every site on the centos mirror list, checked 10 to 15 in the US, but the only one I found that even had a folder for a debug_info sync stated: "due to size this has been moved to debuginfo.centos.org" I am only syncing debuginfo.centos.org::centos-debuginfo/7/x86_64 and i386. Should I pull from here? Is there a better place? Just trying to do the right thing net/netizen resource usage wise Any help/guidance appreciated thanks all
