--- Comment #1 from Xavier Hernandez <xhernandez at datalab.es> ---
This is not a bug. It's how it works.

If you have a 2 + 1 dispersed volume, and one of the bricks is damaged (brick2
has been manually damaged), another failure on another brick (in this case
brick3) makes the file or directory inaccessible (you see an Input/Output
error).

If you need to support more than one brick failure, you should use a bigger
configuration, like a 4 + 2.

Regarding the healing problem, current version of dispersed volumes do not
automatically heal its files and directories. They must be manually healed. The
recommended way to do a full volume heal is this:

    find <mount point> -d -exec getfattr -h -n trusted.ec.heal {} \;

It's expected that version 3.7 will integrate automatic self-healing for
dispersed volumes.
