How to recombine mirror pair

Sorry, but you are in a state where SoftRAID's driver does not know what the differences are on the two disks.

So as you anticipated, you need to:
delete one of the two volumes
(You must manually decide which to keep, which one to delete - they may be near identical, but make sure recent files were not saved to different volumes)

"Add secondary" and let it rebuild. At least this is in the background, so nothing to worry about. You can use your volume while this rebuild happens.

You may also need to "remove missing secondary disk" at the end of this process, depending on which volume you keep.

Thanks, I've started that process, all gone smoothly I just have to wait now. Looks like it may not take as long as I suspected.
Cheers

I am not sure if I am perhaps in the same situation. My Boot drive, which is not a soft raid drive, failed in my xserve. There are three Drive bays in this xserve. 1 is the boot drive, 2 and 3 are a pair mirrored through soft raid.

I have replaced the boot drive (Drive 1) and reinstalled to OS and Softraid.

The two mirrored drives now seem to think they are each parts of separate SoftRaid volumes (with the same name!) and that each of those separate SoftRaid Volumes are missing a disk.

But when it was set up initially, Drives 2 and 3 were mirrored to create the one SoftRaid Volume.

Is there any way that I can get the system to recognise that the drives 2 and 3 should be mirrored to that one SoftRaid Volume? I have attached the picture. Grateful for any assistance.

I can see this happened on August 23.

You have to do the following:
Open both volumes. Decide which to keep (Note that either volume or both may contain current data, so you need to fix any issues where both volumes have different data)
rename in Finder the superfluous volume
Run SoftRAID
Delete the superfluous volume.
"Add Secondary disk" and let it rebuild.
YOu may need to use "remove missing secondary disks" when done to reset the counter.
The volume is totally usable while the rebuild happens.

I note the volume are unmounted. If they cannot be mounted, then you may need Disk Warrior to repair the directory.

Thank you for this. It solved my problem. I suspect the error arose because time machine did not understand how to deal with the configuration when I restored the boot drive from it.
