[geeks] recipe for Linux / iSCSI / thin provisioned space

[Patrick Giagnocavo]

 Hi,

Can anyone point me to a blog post or good tutorial about the best way to:

1. have a Linux server which acts as iSCSI target (server) - easy enough
to install CentOS 5.5 and tgtadm on it;

2. then do thin provisioned space of those iSCSI target(s)

I have successfully provisioned a small iSCSI target that is "thick"
(takes up 1GB disk space when provisioned as 1GB of space), but
obviously this is not terribly useful.

This is a few commands in ZFS, not so under Linux it seems.
