Re: [Bacula-users] restore on solaris unexpected free inode / problems with doors

Well, about the only other thing I can think of is that these are some sort of
*special* Solaris file that Bacula doesn't know how to properly restore or
should not be restoring (sockets?) or there are some sort of access control
lists that are interferring with their creation, or they are files in some
special system directory that probably should not be restored (e.g. /sys
or /proc if it were a Linux system).
Taking a careful look at the same files on a running system will probably give
you a clue. If they are sockets, you can safely ignore the error messages.
Version 1.39.x will not try to restore sockets if I am not mistaken.
A good test of whether or not the restore worked is trying to boot up the
system and run some programs on it -- e.g. a Window system, and build Bacula.
Just the same, I would not be comfortable until I understood the nature of
those errors ...
