Q01: How to add XFS to Linux?
Ans: In recent version of Linux (Redhat, CentOS, etc), XFS is not included in the kernel anymore, but you can always add it as a module. Run "yum install
- kmod-xfs xfsdump xfsprogs", and after these packages installed, you can run mkfs.xfs to format and mount the partition as XFS.
Ans: No. Windows XP X86 is using MBR which cannot recognizes any partition larger than 2TB. However, Windows XP X64 and Windows 2003 server
- support GPT, which can support up to 256TB. But, since Windows XP 32 bit cannot recognizes GPT partition, so any GPT volume is "protected" and cannot
be read / write in Windows 32 bit.
Ans: The is one default setting's problem in the 3U raid controller, follow these steps to solve it:
- Enter password "0000" in the LCD panel.
- When creating the raid, in the option > 2TB, there are three Options: No, For Windows, and LBA 64
- Choose LBA 64
- In the menu, choose "U320 SCSI Target Configuration",
- In "Two TB CDB Sel." by default is "12 Bytes CDB", Must change it to "16 Bytes CDB."
That's it. When connect to the Linux system, and run parted again, it will show all the TBs.
Ans: Areca does not provide any drivers for Debian 3.1, howerver, as their website mentioned:
One of our customer create Debian installation ISO images, it
- supports Areca SATA Raid cards in kernel. you can install Debian directly to our Volumes.
the website address is : http://www.tienhuis.nl/areca/
So download the ISO image from the website, and install Debian to it. After installation, must update the SMP kernel from: http://huge.cajones.org/~dick/debian/kernels/
Ans: First of all you cannot use fdisk to create the partition table, because fdisk supports msdos disk label only, you need to use parted to create the
- partition table. Assume this is the second volume, /dev/sdb. Follow these steps:
p (Press p and it shows the range of the volume, ex: from 0 to 4198881)
mkpart primary ext3 0 4198881
q (Press q to quit, parted automatically saves it to you)
mount /dev/sdb1 /mnt
Ans: Assume the more than 2TB volume is in the second raid controller, the /dev/da1, follow these steps:
gpt create -f /dev/da1
gpt show /dev/da1
gpt add /dev/da1
mount /dev/da1p1 /mnt
Ans: After installation of Fedora Core 5, boot into the text mode, (run level 3) and vi /etc/X11/xorg.conf, and commenting out "Load "dri".
Ans: Once AMD PowerNow is enabled, the driver for powernow-k8 is loaded, and then you can set the cpu frequency. Type "cpufreq-info", it tells you that the
- cpu range is from 1000MHZ to 2.2 GHZ (min to max), and the cpufreq governor is userspace, which use the minimum cpu speed. You need to change the governor to performance in order to get the maximum cpu speed. Type "cpufreq-set -c 0 -g performance" to set it for cpu 0, and type "cpufreq-set -c 1 -g performance" to set it for the second cpu. But next time you reboot the system, this setting will gone, so you need to add these two commands to /etc/rc.local.
You can enter CMOS, Advanced, AMD PowerNow configuration, and disable the PowerNow feature. but these messages will appear in dmesg: powernow-k8: MP systems not supported by PSB BIOS structure.
Ans: To solve ths problem, you need to enter CMOS, under Boot/OS Installation, enable "64 bit Linux 2.6.9", save and exit.
Ans: The Hard disks are fine, the problem is that all the Hard disks are spined up during boot up at the same time. To solve this problem, visit:
