The redhat-upgrade-tool man page states “the –iso image must be on a filesystem listed in /etc/fstab”, is that true in your case. @cvoltz: not sure if related but could be. But more likely the upgrade tool entered some kind of loop, I suggest canceling it and run it again with the verbose option (-v) so you have a better picture of what it’s doing.
6 as there were a lot of security updates since 6. @mischa: if you don’t know what you’re doing you might end up with a broken desktop environment as documented here under “Know issues when upgrading”: http://wiki. Org/TipsAndTricks/CentOSUpgradeTool
I suggest you don’t perform the upgrade, but you might want to update your system to CentOS 6. Just run ‘yum update’.
But yesterday the values where not only higher, but also even completely missing from our monitoring system, so no data received. We monitor the response time for those services, and average response time is usually < 1sec (with some exceptions, mostly due to network latency also for nodes in other continents). Here is a graph from our monitoring/Zabbix server :.
Stack Exchange network consists of 172 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers.
We have made every effort to preserve the existing end-user experience that is available with YUM 3. YUM 4 provides significant improvements such as fast dependency resolution and a stable, documented API. This is the primary reason for making YUM 4 available for testing now. See the references below for detailed improvements.
As a server administrator, . When your screen freezes, reboot. That is the standard solution that even tech experts often dish out to common users. If your system gets slow, reboot. If you have grown up using Microsoft Windows on your desktop or laptop, you are probably accustomed to the universal solution to most problems: reboot.
In my experiment, I use files instead of hard drives, where the corresponding files live in a network share (mounted via NFS). Typically when we build the ZFS server, the members of the RAID are the hard drives. Since the bottle neck of the I/O will be limited by the network, I include a network bonding to increase the overall bandwidth. The idea is pretty simple.
This generated ISO is the one we will be using on all of the Infiniband systems. We need to rebuild the Mellanox ISO to support our current kernel. This is where the fun begins. We’ve got all the files we need now. We need to mount it up, run the scripts, and move our new ISO into our mlx folder.
Bash is one version of the shell that is very popular with Linux distributions. Linux comes with a very powerful tool built into it. It is called the shell. If you can learn even basic Bash scripting, you can simplify and automate a lot of tasks you would normally have to manually perform on your .

That’s because with the stock kernel I was having issues toggling screen brightness and after some googling around I had found that 3. 2 fixes that and few other issues (while on Stella Linux 6.
In this article we will explain how to easily upgrade to latest Linux kernel version on your CentOS 7 distribution using ELRepo repository.
When it runs for the first time, it tries to automatically select the best performance profile for the system by running a couple of comparisons. Conf is then used as the rulebook to see what matches and what doesn’t. The tuned package is installed and enabled by default. It does this by checking virt-what output, and using the contents of /etc/system-release-cpe. The tuned file /usr/lib/tuned/recommend.
