How can I replace failed drive on software raid?

If the drive fails in a redundant raid array (Raid 1, 5 or 6) just go under Software Raid - Raid Info and select option repair and follow the wizzard.

Alternatevly you can replace it by defining the replacement drive as hot spare in the software raid management. Rebuild will then start automatically.

Guest users are unable to log in


User guest has been assigned to a share (under access control) – still the guests are unable to login to the share.


Windows users are automatically trying to log in with their own local user and password and not with account guest therefore the login attempt will be rejected.

If the share is mapped with user guest - no password then the user will be able to log in.

The easiest way is to enable guest account under network - domain and workgroup when joining the workgroup or domain. In this case all users that are not known to euroNAS will be treated as guests. In guest is assigned to a certain share this users will be able to log in automatically.
