Filesystem-specific notes

1. ext3_
|
|
|
|
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.
|
|
|
|
ext3
|
|
====
|
|
|
|
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::
|
|
|
|
$ sudo tune2fs -l /dev/sda1 |grep feature
|
|
Filesystem features: has_journal ext_attr resize_inode dir_index filetype needs_recovery sparse_super large_file
|
|
|
|
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
|
|
`http://wiki2.dovecot.org/MailboxFormat/Maildir`_ for some hints.
