Hello, If anyone happens to run into an issue with trying to mount/use image files with libguestfs when ksplice is installed on the host system. This is the workaround. Create file: '/usr/lib64/guestfs/supermin.d/zz-ksplice-workaround' with the following contents: /sbin/depmod.ksplice /sbin/ksplice-depmod /sbin/modprobe.ksplice /sbin/modprobe.ksplice-orig /sbin/depmod.ksplice-orig You may need to...

Hello guys, I saw that a few days back there was a talk about encorporating the ksplice toolchain into CentOS and creating rebootless upgrades to the CentOS kernel. I'm really interested in helping for that. Where/how we can start work ? Best regards, Marian Marinov -------------- next part -------------- A non-text attachment was scrubbed...

...lso, if your researchers can't write code that performs checkpoints, they're going to be awfully unhappy when a bug in their code makes it segfault 199 days into a 200 day run. Scheduled downtime and rolling cluster upgrades is a necessity of HPC cluster administration. I do wish that the ksplice/kpatch stuff was available in CentOS. -- Jonathan Billings <billings at negate.org>

Hello, I always wanted to ask: do you need to reboot after updating packages like kernel, glibc, postgresql? Or do you need to restart the postgresql service after updating it with yum?

Indeed newer features like ksplice can /reduce/ the number of reboots required. jh

Hi all, Is it possible to reload the dom0 / host node's kernel with a newer one, without rebooting the server? I know kexec can do something like this for security patches, but I don't know much about kexec, and I don't want to mess up a production server either. So, has anyone done something like this before? I need to load a new kernel for one of the domU's iptables to work, but

Hi all, I'm curious. If I do yum update (which include kernel update) but don't reboot. Is it OK? I mean apart of the kernel, other things like services, we don't have to reboot if we don't have the chance to do it (postponing to some other date), right? Thank you.

...ngly connected. These things act together to create a situation where bugs are more likely in the core components, where it's harder to update a system without fully rebooting it. But there's hope. There are a number of efforts to produce a system to update the kernel without reboots (ksplice, kgraft, kpatch, and KernelCare). More developers are writing unit tests. Code analysis tools are improving. Both the number of bugs produced and the cost of fixing them are getting better over time, too. > We do not need plug-and-play; or usb hot-swapping; or hibernation; or > screen...

Halo Valeri, let's think about what a hpc cluster is for. Second, one should always ask the question where security is to be applied,then one can come to the following decision: - The firewall is placed in front of the cluster. - After you have found a safe base for this, you freeze it. - We have a rsync of centos and epel on the head node. >From here, we can always reinstall a node
