Re: Importing MYSQL DB Lock?

Being the SA referenced in this question I wanted to point out a few things:

Before dropping the DB the ibdata files were deleted( we use table per idb ) for that DB
The database was then dropped and recreated
Upon import the first table is ad and it seems to already be locked.
To me this would mean that there is still lock information stored in the InnoDB metadata which is held in the shared ibdata file. Last time I had problems with the InnoDB metadata being out of sync with the individual table ibdata files I blew away everything and re imported. When I tried to restart on that occasion MySQL refused as it couldn't find table ibd files which had been removed, but were still in the metadata.

The persistent problem here is removing the ibd files via command line rather than doing a drop database. pebkac.
