Tahoe storage servers use a large number of subdirectories to store their
|
|
|
|
|
shares on local disk. This format is simple and robust, but depends upon the
|
|
|
|
|
local filesystem to provide fast access to those directories.

For moderate- or large-sized storage servers, you'll want to make sure the
|
|
|
|
|
"directory index" feature is enabled on your ext3 directories, otherwise
|
|
|
|
|
share lookup may be very slow. Recent versions of ext3 enable this

|
|
|
automatically, but older filesystems may not have it enabled::

If "dir_index" is present in the "features:" line, then you're all set. If
|
|
|
|
|
not, you'll need to use tune2fs and e2fsck to enable and build the index. See
