Using ZFS Case insensitive filesystems with Samba

Here's something I learned when working with the FreeNAS folks :

ZFS can be configured to be case insensitive when
you create the filesystem (NOTE - cannot be altered
*after* the filesystem is created).

zfs create -o casesensitivity=insensitive filesystem

https://www.freebsd.org/cgi/man.cgi?query=zfs&apropos=0&sektion=0&manpath=FreeBSD+8.1-RELEASE&format=html

Once you've done this set the following in the
share definition in your smb.conf :

[ZFSSHARE]
	path = /foo
	case sensitive = true

and Samba will go *much* faster for
directories with large numbers of files
(we don't have to scan the directory on
every cache miss) !

This should also work with ZFS on Linux:
