[Users] Bug: adding LocalStorage Data Centers

Mon Nov 11 17:17:04 UTC 2013

Hi Sven,
What is the path of the third local storage domain you can't add.
Could it be the same as the other existing connections (/home/DATA,
/data/images/rhev)?

It could be an issue of this bug https://bugzilla.redhat.com/1023739 - -
Cannot create same Local SD path on different Hosts

Regards,
Maor
