Hmm, I didn't notice that.
I did a check on the NFS server and I found the "1ed0a635-67ee-4255-aad9-b70822350706" in the exportdom path (/data/exportdom).
This was an old NFS export domain that has been deleted for a while now. I remember finding somewhere an issue with old domains still being active after removal but I cannot find it now.
I unexported the directory on the nfs server and now I have to correct mount and it activates fine.
Thanks!
Still weird that it picks another nfs mount path to mount that has been removed months ago from engine.
This is because vdsm scans for domains by storage i.e. looking up under /rhev/data-center/mnt/* in case of nfs domains [1]
It's not listed in the database on engine:
The table lists the valid domains known to engine, removals/additions of storage domains update this table. If you removed the old nfs domain, but the nfs storage was not available to the time (i.e. not mounted) then storage format could fail silently [2] and yet this table would still be updated for the SD removal. [3] Haven't tested this out, and may need to unmount at a very specific moment to achieve this in [2], but looking around with the kind assistance of +Benny Zlotnik <bzlotnik@redhat.com> on engine side makes this assumption seem possible.

So there still is something weird going on there.
