I have a three disk raid 5, with 500GB disks.
This is close to being full, and whilst I can just add another disk and rebuild to add another 500GB, I would prefer to replace with 1TB disks. So i have some questions.
Can I replace these disks one by one with bigger disks? I... (1 Reply)
Hello Unix Community:
My task to figure out how to add a 20G volume to an existing EBS Array (RAID0) at AWS.
I haven't been told that growing the existing volumes isn't an option, or adding another larger volume to the existing array is the way to go. The client's existing data-store is... (0 Replies)
Hi All
I have a RAID 5 array consisting of 4 drives that had a partial drive failure in one of the drives.
Rebooting shows the faulty drive as background rebuilding and mdadm /dev/ARRAYID shows three drives as in sync with the fourth drive as spare rebuilding.
However the array won't come... (9 Replies)

Hi guys,
I'm new to RAID although I've had a server running raid5 for a while. It was delivered preinstalled like this and I never really wondered how to monitor and maintain it. This quick introduction just to let you understand why I'm such an idiot asking such a silly question.

color.4th
COLOR.4TH(8) BSD System Manager's Manual COLOR.4TH(8)NAME
color.4th -- FreeBSD color-detection boot module
DESCRIPTION
The file that goes by the name of color.4th is a set of commands designed to simplify color logic. The commands of color.4th by themselves
are not enough for most uses. Please refer to the examples below for the most common situations, and to loader(8) for additional commands.
Before using any of the commands provided in color.4th, it must be included through the command:
include color.4th
This line is present in /boot/loader.4th file, so it is not needed (and should not be re-issued) in a normal setup.
The commands provided by it are:
loader_color? Returns FALSE if the loader_color environment variable is set to ``NO'' (case-insensitive) or ``0''. Otherwise
returns TRUE (unless booting serial).
The environment variables that effect its behavior are:
loader_color
If set to ``NO'' (case-insensitive) or ``0'', causes loader_color? to return FALSE, indicating to many modules that color
should not be used.
FILES
/boot/loader The loader(8).
/boot/color.4th color.4th itself.
/boot/loader.rc loader(8) bootstrapping script.
EXAMPLES
Standard i386 /boot/loader.rc:
Use color where applicable:
loader_color="YES"
SEE ALSO loader.conf(5), loader(8), loader.4th(8)HISTORY
The color.4th set of commands first appeared in FreeBSD 9.0.
