Ceph – distributed object storage

http://ceph.com/

What is Ceph?  Ceph is a free software storage platform designed to present object, block, and file storage from a single distributed computer cluster. Ceph’s main goals are to be completely distributed without a single point of failure, scalable to the exabyte level, and freely-available. The data is replicated, making it fault tolerant. (ref)

There was an IBM write up here or you can just ready the cached copy. (l-ceph-pdf)

Linux Bonding RHEL style

This should work on RHEL, Centos, and Fedora alike.

 

bond0 = eth0 and eth1
ifenslave -c bond0 eth1 (will change the currently active slave to eth1)
echo -eth0 > /sys/class/net/bond0/bonding/slaves (will remove eth0 from the bonding interface running)
echo +eth0 > /sys/class/net/bond0/bonding/slaves (will add eth0 to the bonding interface running)
