Mount NTFS ON RAID 0 (Fedora 10)


Hi All
actually i am brand new in linux and want to see my NTFS partitions as i got 2 sata HD and make them raid 0 performance,and i got both OSs on it,i am using fedora 10 and can not mount them by defualt command and i got this error


[root@localhost ~]# mount /dev/sda2 /mnt/windows -t ntfs -r
Error opening '/dev/sda2': No such device or address
Failed to mount '/dev/sda2': No such device or address
Either the device is missing or it's powered down, or you have
SoftRAID hardware and must use an activated, different device under
/dev/mapper/, (e.g. /dev/mapper/nvidia_eahaabcc1) to mount NTFS.
Please see the 'dmraid' documentation for help.

thanks for help and suuupport

Dude. First off, awesome name. !!!!!!

Secondly: welcome to linux in all respects.

Thirdly: Redhat is run by facists. But that's just my personal opinion.

Fourthly: Talk in english if you want help, else we have to translate your geek speak. Sometiems it works, sometimes it doesn't.

Fifthly: post (show us) your /etc/fstab. Then, look at your /dev/ directory. There may be soemthing there that works to mount 'automatically'. I.e., to mount a cdrom, you just type
mount cdrom

There may be a mount md0, or raid0. I'm not as familiar with fedora (mostly because they are RUN BY FACISTS) but I digress. Use it at school, but not happy about it.

Sixth and Lastly: did you read the dmraid documentation? if the above fails, do what is says and try to mount /dev/mapper/WHATEVER(sata, or something).

Wow! hope you respond to this message, else I just wasted about ten minutes of my life.

!!!!! how are your hard drives set-up? Were these partitions originally raided in an unmirrored stripe by windows? I am presuming you are using mdadm for this, can you confirm if the actual partition sda2 exists within /dev/ or not and the other partition on sdb(?) that you are trying to raid this with.

Seriously... all that is being is little more then slightly irritating. These topics are for helping, not preaching.

@r3sistance: apologies. humor: http://www.ubersoft.net/comic/kp/200...dons-aftermath. Also, I was a little drunk.

You have to be root to see /dev/anything. so

$su

or $sudo su

then look in /dev/

then $exit to stop being root.

You should not be using a browser whilst running as root. And to "look at" a directory, use the ls command.

The package "dmraid" must be installed before you can see a motherboard raid. Once installed, as your first post suggested, look in /dev/mapper. Your arrays will end with a number. The device will not. e.g. "/dev/mapper/nvidia_eahaabcc1" is a mountable partition, "/dev/mapper/nvidia_eahaabcc" is not mountable and can be considered the array drive.

Also, I forgot to mention that you need to install the ntfs-3g package if you plan to write to this ntfs partition.

I already Installed the ntfs-3g packages and this is what i saw under /dev/mapper
[root@localhost dev]# control via_cgddjifhah via_cgddjifhahp1 via_cgddjifhahp2 via_cgddjifhahp3 via_cgddjifhahp4 via_cgddjifhahp5 via_cgddjifhahp6

i mean by root that i can su to be root any time but mostly I am using my normal username when i am using the GUI

I didnt thought it so complex to got a command to mount this NTFS while using Raid because most of servers are running on Raid

This is tricky, unless their is a corrosponding partition for this to be raided with your not gunna be able to mount it as a raid anyway, if it's literally raid 0 then you'd need both partitions mounted together as one raided device using say mdadm to declare both devices in raid just because of the way that raid 0 works. You can't read a raid 0 with only one half of the data.

since this is a dual boot system with windows windows (that I am guessing you recieved pre-installed?), is their any raid reported by windows itself? (under disc management section of computer management, can be found under administrative tools in the control panel). Problem is, until it's known what is going on, if their is a raid configuration, and if their is, how it's split over the two hard drives, hard to tell exactly what is needed to be done to mount this in linux.
