Today I bought 2 3 TB hard drives to use in my new server.
I'm writing this in case other people aren't aware that some of the
traditional hard drive management methods don't work for drives larger than
Specifically, fdisk and MSDOS type partition tables.
Here is how I created a single partition on my 3 TB drives.
#parted -a optimal /dev/sdb
(parted) rm 1 <- this removed the 2TB partition that fdisk made.
NOTE: fdisk has a 2 TB limit, apparently forced by MSDOS style partition
tables. Ever heard the story about how the width of a donkey ultimately
determined the diameter of the space shuttle ?
(parted) mklabel gpt <- this is NOT making a label for the drive. "man
parted" is your friend.
(parted) mkpart primary ext4 1 -1 <- this makes the partition itself, using
the entire drive, which is what I wanted.
# mkfs -text4 /dev/sdb1 <- this formats the partition
#e2label /dev/sdb1 myth <- this gives it a label, as used by mount in
fstab, ie "LABEL=..."
It turns out that the whole process can be done from within gparted, if you
know what you are doing.
The first thing you need to do is create the partition table.
IF you have used fdisk on the drive previously, the partition table type is
going to MSDOS, which has the 2TB limit. If you continue with the MSDOS
partition table, gparted will allow you to select a 3TB partition to make,
but it will give you the following error:
partition length of 5860528002 sectors exceeds the
msdos-partition-table-imposed maximum of 4294967295
To get around this, select Advanced on the partition table options window
and set the partition table type to gpt.
Then you can proceed as you normally would to partition a drive with
gparted. Ie add new partition(s), set the partition type, labels, etc.
At this point you have an ext4 formatted 3TB drive.
However, in F15 KDE at least, it doesn't seem to automount like a drive with
an MSDOS partition table. The drive will not automatically appear in the
Places column in Dolphin, for example. Nor will it appear in the list
created by df.
However, it is available to manually mount. Ie, #mount /dev/sdb1 temp,
just like the old days.* And once you do that, it appears in the df list,
though still not in the Places column in Dolphin.
I hope this helps someone.
*This might be particular to my machine being that the drive is a hot swap
SATA device and I did not remove it and replace it. However, drives with
MSDOS type partition tables auto mounted using the very same command

Behold, they are one people, and this is only the beginning of what they will do. And nothing that they propose to do will now be impossible for them.
According to most recent RFCs IPv6 addresses starting with 0xFD are
considered unique local addresses. This is more or less equivalent to the
IPv4 private addresses.
I have the following IPv6 address configured on eth0
When I run ifconfig eth0 I get:
eth0 Link encap:Ethernet HWaddr 00:18:F8:0E:76:F2
inet addr:10.0.0.65 Bcast:10.0.0.255 Mask:255.255.255.0

Notice that the entry for fd00:1111::41/32 shows its scope as Global. I
would have expected something else. Am I just misunderstanding the concept
of local vs global?

2) how can I make all personal data flushed at

Any experience in library installation
Looks like I'm not going to be much help.

I don't know the full list. The distro install instructions list packages required for each supported OS, suggesting someone has the list you need.

I don't see anything unnecessary in this: http://www.openfoam.org/git.php
>3. Wanting to be compiled in the location it's installed to is bad...
There's still a lot of old-school left in OpenFOAM. Object files go into subdirectories within each library. The #include strategy is particularly stupid - each library requires a directory with shortcuts to all files in its scope. There are scripts that attempt to maintain these, but they don't always work, and the fail mode of name collisions is apparently to destroy both files.
>4. Along those lines, is the entire source tree really needed during use?
The library is broken down into multiple sub-libraries. It shouldn't bee too hard to pull it apart to make large, logically grouped extension packages, like openFOAM-core, openFOAM-chemistry, openFOAM-lagrange, and so on.

Outside my realm of expertise - I don't know much about the third party stuff. Some are pretty standard: openmpi, cmake. But then again, some of them are pretty old too, and I guess we'd have to package these ourselves.
>6. I'm not sure if the built-in wmake tool is acceptable, it seems to

I think wmake is native to OpenFOAM - although openwatcom's description of theirs is identical. The wmake source files have OpenFOAM's standard comment headers. If you have to get rid of it, you are right about FreeFoam. Last I heard, the project is still unfinished, but the guys who manage the OpenFOAM-extend fork are borrowing FreeFoam's cmake solution for their Windows port. I understand the Windows port is a huge struggle, and is also unfinished... so I'm not sure how much of the struggle is associated with the cmake aspect.

I didn't realize how much work would be involved. I'd say we give it a little more time to mature. The community is growing, and there's pressure to modernize the project.

Well done devs!
I have a friend, whose Thai wife has never really used computers. She's
learning it now. He had me dualboot his computer with Windoze and F15;
many people do. We are both used that most people don't give F15 - or
Linux - a moment's thought, as they don't know how to use it. However,
this woman - who knows neither Windoze nor Linux - now prefers to boot
F15. My friend asked her why: "Because it's easier!"
Well done devs; stick it in your cap!

Under Fedora 14 the following procedure worked for discovering the UUID
for a USB device.
Look in /dev/disk/by-label for device
Use file cmd to find device assigned
Look in /dev/disk/by-uuid for the UUID assigned (link to same device)
Alas, that no longer works. Anyone have an up-to-date procedure?
