you can find a pretty good overview over different high-availibility
clustering solutions on www.linux-ha.org
it depends on what you want to accomplish. i recommend drbd rather than
rsync for data replication (real-time replication with standard
hardware, working with databases (mysql,postgres,oracle,..), apache,
samba,...). there are some commercial products too (e.g. steeleye
lifekeeper,..)

Hello,
Does Debian Linux implement true clustering (two or more simultaneously
active servers sharing the same physical disks) ?

AFAIK you need special hardware to do this. What you can do in SW though
is to have two servers, that mirror each other eg. using RSync over a
fast dedicated line.
There are various free shared filesystems out there, if you have
hardware that permits shared access to disks (fibrechannel or
some other SAN kit).
There are also NAS filesystems which give a pretty good simulation of
it (lustre for example, although that's a bit immature).
