Here is how I got out of it:
# rm -f foobar/* (with server running! but not accessed by anyone,
its a preprod slave )
mysql> drop database foobar;
mysql> create database foobar;
mysql> source foobardump.sql
I think it was a mismatch in the data dictionary between the database
and its tables.
The 'drop database' failed because the directory was not empty,
and the drop table failed because the tables where not in the data
dictionary.
>>>Everything started with a binary backup of ONE innodb database which
uses ONE file per table.<<<
I think this is a problem with partial ,binary, backups that use innodb
tables, since the data dictionary I think it's anyway the main
tablespace (ibdata1 file)
Q: Is that I am missing something ot it is a tricky situation?
Hope this is helping other people as well
Cheers

rmdir on a nonexisting dir might throw a non-zero exit
* Take your db offline and do an fsck. If you want, you could flush
tables with read lock, then mount -oremount,ro and then fsck - that'll
keep your db up for reads, at least. DON'T let fsck fix things that
way, though - for that you really do need to shut down the db and
unmount the disk.

I am banging my head.
First, is not a file permission problem.
I cant import data on some replication slaves either in binary, or
from a
sql mysqldump.
I use one innodb file per table and I am importing only two
databases on a
dozen.
After a few hours seem that the problem is with the name of the
database,
since I can import on a different database/directory.
I tried to import only the DDL(from the master where the dump
comes from)
to recreate all the tables to 'refresh' the information schema,
then stop the DB, copy the .ibd datafiles in the directory, start
the DB,
and if I do a DESC dummy get:
-------------------------------------------------------------------------------------------
ERROR 1146 (42S02): Table 'foobar.dummy' doesn't exist
-------------------------------------------------------------------------------------------
If I drop the database I get the error in the subject
---------------------------------------------------------------------------------------
ERROR 1010 (HY000): Error dropping database (can't rmdir ./foobar
---------------------------------------------------------------------------------------
If I try to import from the SQL dump:
---------------------------------------------------------------------------------------
ERROR 1005 (HY000) at line 23: Can't create table './foobar/dummy.frm'
(errno: -1)
---------------------------------------------------------------------------------------
I am stuck, any help really really aprreciated!
Cheers
