Increasing disk space by stopping mirroring
My Os is NT4.0 SP6 and I must upgrade in W2k
System partition C: is 1,5Go on Disk 0, Notes/data partition are agregat partition on Disk 0 and Disk 1. 2,3 G at the end of Disk 1 are free.
Before Upgrading I'd like to have more space on C: and I dont't know if I can do it by changing Raid 0+1 to Raid 0. What will append if I do that ? What will I see in windows, more space in C: or simply free space on disk 0 ?
Thank all in advance

Re: Increasing disk space by stopping mirroring
If you go from 0+1 to 0, you loose all reliability and the failure probability will increase dramatically, because failure of 1 disk out of you 4 disks then will destroy your array.
Perhaps you could use tools such as Partition Magic et.al. to move your partitions to the end using the free 2.3 GB and then expand the C partition. Note: I would recommend a backup before doing this also.

Re: Increasing disk space by stopping mirroring
If it works, you will *not* automatically have more free space on the logical disk for C:. You will rather see free space at the end of the disk array. Next step would be to extend the logical disk. Assuming this works, too, you will *still* won't have free space on C:, because the partition table is not updated.
That's when the partition management that Karl mentions comes into play. I fully agree with his suggestion that you make sure you have a very good backup before you start. This type of work has a high potential to destroy all your data. Good luck!

Re: Increasing disk space by stopping mirroring
So, to maintain reliability, I think it would be better to use the 2,3 Go free space but it is at the end of the other logical disk Disk1.
Is partitionmagic able to do the work between 2 logical disks ? Will NT4.0 start again with C partition at the end ?
And what about W2k upgrading on such partition ?
Thank you again
