hi,

iscsi can export devices, but not filesystems. if you want more than one server access the same filesystem, you have to go on gfs2 or ocfs2. it’s not so difficult to setup ;-)

and what about iet vs tgt? what’s the best iscsi target for linux?

many thanks,

ftaurino

xiaolong
iscsi cannot do file sharing. because, unlike nfs, there is no locking.
just like fc san.
you can make a lun into a zone visible to more than 1 server, you can even access the lun from them. but you do not do that because it is just a raw access. not locking.

Great how-to, thanks.

tgt is available on Centos 5.2. (details on the introduction to RHEL 5 is at http://rhn.redhat.com/errata/RHEA-2007-0713.html)

To install:

# yum install scsi-target-utils

Works as detailed above.
