Hi Viraj,
Gluster Ver. 3.x supports replication over WAN but currently very
limited. I assume it will expand as time moves on.
As for ISCSI. I doubt Glusterfs will ever support ISCSI. ISCSI
operates at the block level. Gluster only works on the filesystem
level. The only way to have iscsi on Gluster would be to export an
iscsi target that is a file on gluster.
As for snapshot and deduplication in CIFS, I really don't know, I'll
pass that on to the other Gluster-users :)
Hope this helped,
Pat

Hi Pat,
Actually we are looking for product that will do replicated between
server in WAN
but it should also support iscsi as we will be mounting it on windows
server, as we will be replicating data of windows volume
so i thought that if i could create a iscsi lun on linux
system(centos) and mount it on windows server as a volume and then
those iscsi lun can be replicated across the many server. actually we
are preparing for DR.
we will create the DR server in AWS EC2
we tried some products and they are quite expensive so we are doing
some research in open source.
Also does glusterfs support snapshot and deduplication in CIFS?
and when could glusterfs start supporting iSCSI any timeline given.
Thanks,
Viraj

Hi Viraj,
My experience with LVM is quite limited, but I think I can help a
bit. Glusterfs is a file system only. It does not contain the
block level hooks required by LVM, so you will not be able to
directly mount it as a block level device. If you really want to
use glusterfs as the back end for the LVM you would need to mount
glusterfs into a directory and then use a loopback file on the
glusterfs mount point and then use that loopback file for the LVM
mount.
This approach seems like a lot of work. What is your desired end
product? Do you want gluster to serve a filesystem that sits on
top of an iscsi target?
Let me know if I have completely misunderstood what you where asking J
Pat.

*Subject:* iscsi with gluster i want to make it
Hi Patrick,
the gluster community is not replying to my question
can you tell me how to mount the lvm in the gluster fs as i have
made two node in glusterfs
i have added two harddisk to mode the node and made it as a lvm
for iscsi target to work
now i want to mount lvm on the glusterfs as
some what like
**mount -t glusterfs server1:/test-volume /dev/vg1/lvs**
instead of mounting on to a folder
**mount -t glusterfs server1:/test-volume /mnt/glusterfs**
Please assist
Thanks and have a nice day
Viraj
