NTFS, dynamic disk, stripe

sanok · 02-12-2004, 08:38 AM

Hello,
I have problem with mounting drives on my PC.
I have gentoo kernel 2.6.2,
disks on SCSI u160
first is basic (SDA) where I have winxp, boot, swap and user (SDA1-SDA4)
second and thirdy is dynamci disk and I have been created stripe set over these disks (SDB and SDC), which
is created in win and formated as NTFS

How can I mount this stripe?

I don't think you can since the dynamic disk is created and manged through Windows. You best bet is to back up a the data and rebuild the drive as a simple (if that is the term to use) volume. If you want to beable to write to that partition it is better if you use a FAT32 file system, since writing to a NTFS partition is still experimental.

Thank you, but this is not solution.
I use WinXP and Linux. I use stripe over two disks, because of speed, use of FAT32 is not possible for stripe.

You could get a Raid card for the PC. Then install Winodws and Linux on it. This is the only solution I know of if you need the speed of a striped set.

In windows is use of software strip very fast. My machine is at work and I cannot change hardware.
I need some help like "mount -t ntfs /dev/ ......" command to mount NTFS stripe.

As I said before. Windows itself controls the raid configuration on the drive. Since the Windows is not controlling the drive, the partition cannot be read (as far as I know). Maybe there is a way, but I have never heard (just got done searching Google).

I have it !!!!!!!!!!!
I must create /etc/raidtab:

raiddev /dev/md0
raid-level 0
nr-raid-disks 2
nr-spare-disks 0
persistent-superblock 0
chunk-size 64k

device /dev/sdb1
raid-disk 0
device /dev/sdc1
raid-disk 1

then I run "raid0run -a"
and "mount -t ntfs -o rw /dev/md0 /mnt/G"
Of course kernel must be compiled with LDM, RAID and NTFS support

But I cannot write to ntfs, I have another ntfs partitions:

mount -t ntfs -o rw /dev/sdd1 /mnt/D

but write not work : permission denied

Can anybody help me?

Gratz on getting it working. On the NTFS write ting, there should be a place in the kernel where it supports writing to NTFS. It is exxperimental though.

I have already ntfs write support turned on in kernel, but it still not work
