"Requested Operation Is Not Supported" When Trying to Add a Mirror Volume


Please refer to Microsoft Article ID: Q242436 for this question.

I have some win2k systems set up as follows:
- a single, dynamic disk with 3 simple volumes
- file systems are NTFS

I typically use LDM and "Add mirror..." to create duplicates of these drives (then store the mirrors offsite as part of a disaster recovery plan).

However, I just added a 4th simple volume to these production sytems.  And now I am running into the following problem (Microsoft Article ID: Q242436):
"Requested Operation Is Not Supported" When Trying to Add a Mirror Volume

None of their solutions seems to be able to solve the problem I currently have of not being able to mirror my production boxes.  Any thoughts???

Another work around for this is to backup the volumes on your target disk to a network drive; you can then delete all partitions on the target disk, upgrade it to dynamic, repartition & restore from your backups.

Future mirrors to the target disk will no longer experience this problem as the target disk will be considered a "pure" dynamic disk.

WARNING: Be sure to verify your backups before deleting your partitions; backup file failure could cause the loss of important documentation.

Hope this helps!
