Skylake install errors for CentOS-7
by Johnny Hughes 06 Mar '16

06 Mar '16

There were some install issues with some Intel Skylake chipsets/processors for CentOS-7. We have created a newer installer to fix this issue and the ISOs (CentOS-7-x86_64-DVD-1602-99.iso or CentOS-7-x86_64-Minimal-1602-99.iso) are available here: http://buildlogs.centos.org/centos/7/isos/x86_64/CentOS-7-x86_64-DVD-1602-9… http://buildlogs.centos.org/centos/7/isos/x86_64/CentOS-7-x86_64-Minimal-16… sha256sums: CentOS-7-x86_64-DVD-1602-99.iso: c226525cc5b47ffd32d8d082d8b316cb8f51592939f1b12d0dc846ff86d02e32 CentOS-7-x86_64-Minimal-1602-99.iso: 355eea6cc097e5f16805d075f27d2949aa17e8806127e4b361dcb2aef1eafe68 This is based on the latest released kernel (kernel-3.10.0-327.10.1.el7). This ISO set also has all current CentOS-7 updates rolled in including the new glibc. ========================== NOTE: Users who are not having issues what who want the latest ISOs should continue to use our normal ISO sets available here: http://buildlogs.centos.org/rolling/7/isos/x86_64/ Thanks, Johnny Hughes

inotify - triggering scripts based on file events
by michael gordon 06 Mar '16

06 Mar '16

We allow our third party clients to upload files for processing via ftp. Once the file is done a java app is triggered to process the file and move it to a processed folder. How do we know when the file is done writing,the file events we have observed include create, modify. These dont help since the ftp program writes file contents in blocks and then triggers the modified event, there is no finish event. What can you recommend -- *Michael Gordon* *Email: mgordonabc@ <gordonm(a)rada.gov.jm>gmail.com <http://gmail.com>*

[Discuss] Pulp/crane as container repo for CentOS Container Pipeline
by Mohammed Zeeshan 06 Mar '16

06 Mar '16

Hi, I am Mohammed Zeeshan Ahmed, part of Container Tooling Team at Redhat, working on the registry component of the CentOS Container Pipeline. I have been trying to get pulp/crane to work for sometime now to get it to fit into the pipeline. I have setup pulp/crane on a single node (self signed certificates) while a second node acts as a client (pulp-admin and docker) currently stuck at this point http://pastebin.centos.org/40926/ and would appreciate any help in getting things to work. Thanks in advance. -- *Mohammed Zeeshan Ahmed, * +919986458839 Bengaluru, India https://mohammedzee1000.wordpress.com/ <http://mohammed-zeeshan.strikingly.com>

How to build CentOS 7 AMI
by Alan Ivey 04 Mar '16

04 Mar '16

Hi everyone, I'd like to revisit the thread about how the CentOS 7 AMIs are created ( https://lists.centos.org/pipermail/centos-devel/2015-July/013652.html) and see if the process can be published in the https://github.com/CentOS/sig-cloud-instance-build repository or another relevant location. With CentOS 7 AMIs only being available in the Marketplace, all resulting EC2 instances have the Marketplace codes attached to the EBS volumes. A significant restriction of this is that a resulting image cannot be the non-primary volume of an instance unless it is powered down. This presents itself to be a problem in at least the following scenarios: - Unable to attach a CentOS 7 boot volume to another instance for repair without either creating a temporary instance or shutting down an existing one. For example, if you messed up the /etc/sudoers file and logged out, and wanted to repair, you would not be able to repair by mounting to another instance and editing the file without incurring additional (albeit small) cost, or having an existing instance be temporarily unavailable. - The "amazon-chroot" Packer Builder ( https://www.packer.io/docs/builders/amazon-chroot.html) does not work because it starts by mounting a copy of the snapshot tied to the AMI as part of a scripted operation and therefore cannot power off to do so Custom AMIs, snapshots, copied EBS volumes, etc, all have the marketplace codes copied to them and inherit the restrictions. If an org was to use these features for automating environments and was disconnected from the original Marketplace agreement, they may be unaware of this limitation. I would also appreciate being able to have the additional transparency of seeing how an AWS AMI is created as the docker/openstack/etc images from the repository referenced above. This would be useful in environments with regulatory compliance concerns, such as AWS GovCloud, HIPAA, FedRAMP, etc. I understand the benefit that Marketplace registrations allow for the ability to notify users of any changes, and I am not necessarily advocating for switching away from the Marketplace as the primary AMI location. I would like to be provided the opportunity to build a private AMI in the exact same procedure as the official image so as to avert the restrictions provided by the Marketplace. *[Note: I previously posted this question to centos-virt <https://lists.centos.org/pipermail/centos-virt/2016-February/004907.html>, but I did not receive any feedback and I have since noticed that **https://wiki.centos.org/SpecialInterestGroup/Cloud <https://wiki.centos.org/SpecialInterestGroup/Cloud> refers to the CentOS-Devel list for discussion. My apologies to subscribers of both lists.**]* Thank you, Alan

kickstart files for centos 7 cloud images
by Matt Bacchi 03 Mar '16

03 Mar '16

Hello, I'm wondering where I can find the kickstart files used to create the cloud images here: http://cloud.centos.org/centos/7/images/ I've created my own centos 7 image from kickstart but the instance doesn't broadcast dhcp requests (verified using tcpdump.) If I launch an instance using the image you provide (CentOS-7-x86_64-GenericCloud-1511.qcow2 <http://cloud.centos.org/centos/7/images/CentOS-7-x86_64-GenericCloud-1511.q…>) it does broadcast a dhcp request and then comes up on the network. My kickstart file does indicate "network --bootproto=dhcp --onboot=on", but I want to compare it to yours which is working as I would expect. Thanks in advance. -Matt

dm-cache not caching data on 3.18.21-17.el6.x86_64
by Thanos Makatos 02 Mar '16

02 Mar '16

I'm evaluating dm-cache on kernels 3.18.21-17.el6.x86_64 (Xen 4) and 2.6.32-573.7.1.el6.x86_64 (KVM). The test I do is a simple sequential read using dd(1). read_promote_adjustment and sequential_threshold have been set to 1 and 0, respectively. For the 2.6.32 kernel, all seems to be working fine, "#usedcacheblocks" correctly reflects the number of cached blocks based on what I'm reading with dd(1) performance is pretty much native SSD performance. However, the same test on the 3.18.21-17.el6.x86_64 kernel results in "#usedcacheblocks" being stuck to "2" and no performance improvement is observed. Any ideas what could be wrong? How can I further debug this? -- Thanos Makatos
