General :: What Is The Difference Between El5 And El5pae
Oct 26, 2010
sometimes when I install Centos5 on separate machines, it boots with el5 kernel on one and other with el5PAE. Server models are almost identical to one another. such as identical motherboard, identical cpu, difference in Amount of RAM, different Harddrive manufacturer. I'm assuming this is hardware dependant but what is the difference between these two?
I have two servers that have been running link aggregation and VLAN trunking for years. I've installed larger drives in one and done a fresh minimal install. In spite of configuring as before the network will not come up. I did discover that a minimal install will not install vconfig which was causing one particular error when the VLANs tried to come up and this has been solved by installing vconfig. However, at this point the problem appears to be not bonding eth0 and eth1. /proc/net/bonding/bond0 indicates: "bond bond0 has no active aggregator"
If I put the old drives back in and boot the old OS everything starts up fine. I was even able to get it working with:
modprobe bonding ip link set dev bond0 up ifenslave bond0 eth0 eth1 service network restart
however, it does not survive a reboot. Is the a bug in the 2.6.18-194.11.4.el5PAE kernel or the network scripts? The the previous kernel I am running is 2.6.18-128.1.10.el5PAE For what its worth, these are the configurations:

I created 2 virtual machines with VMware Workstation 7. They have identical hardwares. One guest is CentOS 5.6, another is Mandriva 2011. When I try to mount the cdrom in guest OS, in CentOS, I should execute
mount /dev/hdc /path/to/mount
in Mandriva, I should execute
mount /dev/sr0 /path/to/mount
I also remebered in some other Linux variant, I had to use
mount /dev/cdrom /path/to/mount
What's the difference between hdc, sr0 or cdrom? Is there a consistent way to mount cdrom in all Linux variants?
