    I'm hitting my head on the wall for this one, I feel really stupid.

    Long story short. I purchased a new disk and wanted to add it to an existing stripe. I created a new volume next to the current volume (not meant to do that) with the diskutility and deleted it ... went too quick to read the warning message that probably said it would delete all volumes when in fact I though only the new highlighted volume would go. Not sure what happened precisely...

    Anyhow. I know the id's of the disk and how they were configured before the disaster, so there must be a way to recreate the array *without loosing the data*.

    Any help appreciated !!!


    Luckily I saved the configuration before doing anything:

    Code:

    Do you have a backup of your data? The easiest thing in my mind is to create the RAID setup and then do a restore.

    I do, but it's remote. So the last solution will indeed be to rebuild-reload from backup.

    But I had a failure on a NAS a while ago and ended up in a similar situation and could re-assign the disks to the volume in a few commands and all my data was available right away. I don't know how to do this on OSX, doing google search in the mean time of course but can't find the right info so far :-(
