Follow up:
So I have fixed the GPT Table and extended it to fit the new RAID volume. Sadly enough the problem persists.
As the external IT firm did not have any expierence with the CLI interface they set up a test environment for expanding it.
Something goes wrong there and the entire datastore just vanishes in a couple of minutes and cannot be restored.
Ofcourse I do not want this on my replication server, hell to the no on my live server..
Any ideas?
Thanks!
