ntfs

I'm running Ubuntu 8 something and my data is on a mirrored pair of 1TB disks formatted as ext3, and the RAID is via mdadm. I want to move to Windows 7 (yeah yeah I know but Linux aint doing it for me at the moment) and migrate the disks to NTFS. My plan is:

Break the MDADM RAID (by failing one disk logically) Format the 'failed' disk as NTFS Copy data from the RAID array to the NTFS disk (dont care about perms)

Install Windows, (new separate non RAid disk) and my data disk is available.

I've researched this and it seems the easiest way. I dont have another disk to back up to so I think this is my only way. Can anyone see a better/easier way?

Just ran an apt-get update on one of my dedicated servers to be left with a relatively scary warning: Processing triggers for initramfs-tools ... update-initramfs: Generating /boot/initrd.img-2.6.26-2-686-bigmem W: mdadm: the array /dev/md/1 with UUID c622dd79:496607cf:c230666b:5103eba0 W: mdadm:… >>> More
mdadm+zfs vs mdadm+lvm

This may be a naive question since I'm new to this and I cannot find any results about mdadm+zfs, but after some testing it seems it might work: The use case is a server with RAID6 for some data that is backed-up somewhat infrequently. I think I'm well served by any of ZFS or RAID6. Platform is Linux… >>> More
Upon reboot, Linux software raid fails to include one device of a RAID1 array

What tells initramfs or the Ubuntu Server boot process how to assemble RAID arrays?

as seen on Server Fault - Search for 'Server Fault'
The simple question: how does initramfs know how to assemble mdadm RAID arrays at startup? My problem: I boot my server and get: Gave up waiting for root device. ALERT! /dev/disk/by-uuid/[UUID] does not exist. Dropping to a shell! This happens because /dev/md0 (which is /boot, RAID 1) and /dev/md1… >>> More
