[BBLISA] iSCSI - opinions / experiences?

[Steve Revilak]

At my workplace, we have several shared filesystems (a combination of
NFS and samba/CIFS).  They're adequate, but not without some level of
headaches and hassles. (Fedora NFS being a particularly bad headache).

I've been starting to look at iSCSI as an alternative.  I guess my
biggest question is whether it's a viable alternative for NFS/CIFS.
I'm also curious as to how well it handles types of work that are
traditionally reserved for `local disks' (eg - applications that need
reliable file locking).

Have any of you had experience with iSCSI?
