@ -41,28 +41,33 @@ of subdirectories in a directory of the filesystem. The currently most used
filesystem on Linux (ext3) supports only 31998 directories. In order to
overcome this limitation another level of directories has been put inbetween
the content directory and the document directory numbered from 1 to
maxDirID. This allows a theorethical maximum of sq(maxDirID) documents. The
path to the document folder consists of the new path id and the document id
(<pathid>/<docid>). The path id is derived from the document id by the
maxDirID. This allows a theorethical maximum of square(maxDirID) documents.
The path to the document folder consists of the new path id and the document
id (<pathid>/<docid>). The path id is derived from the document id by the
formula
floor(docid/maxDirID) + 1
Hence, all documents with an id from 1 to maxDirID have the path '1/<docid>'.
The limiting factor of this schema is the number of document ids. It cannot
be higher than sq(maxDirID).
be higher than square(maxDirID).
If you intend to switch to the new content directory format, you will have
to set maxDirID to a value > 0 (possibly 31998) and create a new directory
with name '1' below the content dir and move all document directories into
it. If you have already a document with id 1, you must choose a different
name for your new sub directory and rename to 1 after all document
directories have been moved. If you want to keep the current content
directory structure set maxDirID to 0. Make sure the maxDirID remains
unchanged for a content directory.
If you intend to switch to the new multi level content directory format, you
will have to set maxDirID to a value > 0 (possibly 31998) and create one or
more new directories starting with name '1' below the content dir and move
all document directories into it. How many new directories are needed
depends on the maximum document id already used. If the maximum document id
is <= maxDirID, then you will only need one directory named '1'. If the
maximum document id is <= 2*maxDirID you will need another directory named
'2'. If you have already a document with id 1 (or 2, 3, 4, ...), you must
choose a different name for your new sub directory and rename to 1 (or 2, 3,
4, ...) after all document directories have been moved.
If you want to keep the current content directory structure set maxDirID to
0. Make sure the maxDirID remains unchanged for a content directory.

Once you are done with the update, log in as administrator and make an
object check in the admin tools. This will fill the new database field
