XFS install issue
 
I am attempting to implement XFS on a new system.

System:
Supermicro SC846 TQ-R900B - rack-mountable
SUPERMICRO X7DWN+ - motherboard
3ware 9650SE-24M8 - storage controller
10 Hitachi DeskStar 7K1000 - hard drive - 1 TB
8GB Ram
2 Intel Quad-Core Xeon E5420 / 2.5 GHz processor

Installed Centos 5.1 X86 64 from DVD. System on /dev/sda1
? 250GB ext3 (raid 5). /home will be on /dev/sdb1 ? over
7TB XFS.

The problem is that the extras and centosplus items are on hold while
work on CentOS-5.2.


I have not built the centosplus kernel for 2.6.18-53.1.21.el5 as we are
using the builders for 5.2 and kernels take forever to build in the
builders as the debuginfo files are hundreds of MBs in size each.


I also normally build all the extras kmods while I build the centosplus
kernel, so they were also not yet done ... however I did go ahead and
build the new kmods for drbd82, xfs, and kvm for the new
2.6.18-53.1.21.el5 kernel and those have now been pushed to the extras
directory.


They should be synced to the external public mirrors in a couple hours,
and should be on mirror.centos.org now here:


http://mirror.centos.org/centos/5.1/extras/

I dont intend to blame anybody but kmod_xfs was a couple of days late
for previous kernel update and I broke an xfs partition, as recorded
in list archives.

In that thread, I was told to expect such things and test better
because xfs was not in official brunch neither in rhel nor in centos.

Good, because we can not support the extras and centosplus repositories
in the same time frames as the main repositories.

IF you have required kernel modules, then you should probably set the
kernels and the kmods as excluded and NOT update those automatically
(using your yum.conf file).


You can then double check when the updates are available.

I ALWAYS manually upgrade my kernels on machines that require kmods. As
I have said many times, add on repos are supported, but they are not
supported within the same time frames.


I would also not use XFS in production ... but that is just me. If XFS
was production ready, it would be in RHEL. Since it is turned on in
Fedora and since it is purposely turned off in RHEL, one can reasonably
conclude that the upstream people DO NOT THINK it is stable enough to
use in production on RHEL. This is JUST my opinion :D

IIRC, RH's stated reason (stated on the mailing lists in the midst of
folks clamoring for XFS' inclusion) for not having XFS turned on in RHEL
is *not* that it's not production ready. It's that they only have the
resources (read: folks with knowledge in-depth enough to satisfy
enterprise customers) to support 1 FS, and that's ext3.

indeed, when I looked into using XFS for a large scale data store, I had
several XFS 'gurus' (freenode xfs channel) strongly recommend only
deploying it with the help of SGI consulting services, using a SGI
distribution. Since at the time, SGI's long term viability was dubious
(and its not improved any since then, this was about 2 years ago), I
moved on. We are currently using Solaris 10 plus ZFS for this
application, with satisfactory results (except some annoying problems
with marvel88SX sata drivers but thats another issue entirely)

XFS install issue
 
Continuing to get XFS to work


Instaled

# yum instal kmod-xfs.x86_64
# yum install xfsprogs.x86_64
# yum install xfsdump.x86_64
# yum install xfsprogs.x86_64

Rebooted
# fdisk /dev/sdb
Created the partition.

fdisk reported


Disk /dev/sdb: 7731.4 GB, 7731478004224 bytes
255 heads, 63 sectors/track, 939965 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Fdisk will only allowed 267349 (2TB) for the partition.

# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 223G 5.9G 206G 3% /
tmpfs 2.0G 0 2.0G 0% /dev/shm
/dev/sdb1 2.0T 1.1M 2.0T 1% /home

How can I create a partition grater then 2TB.

Also I have noticed that the GUI utilities do not recanisr
the partition at all. Is there anything else that I need
to install?

fdisk can't handle devices that large. You must

1) Use parted
2) mklabel gpt
