Late Friday evening into early Saturday there will be some downtime for system maintenance. First probably around 10:30, I will be taking the server that hosts home directories, out of service for up to an hour. The reason for this is I will be adding a pair of 10TB drives to allow us to increase the size of the /home directory partition.
Next I will be moving home directories to this new partition. While this process will take some time, only during the final aspect when I am ready to switch partitions, will additional downtime be required. At that point I will need to reboot the machine.
Then I will need to reboot a number of other machines in order to make a kernel upgrade active.
