It works, but the performance is very poor. 100MB/s or less
Which are your performance experience?

Hi all,
I have installed the v0.37 of tgt.
To test this feature i follow the
http://ceph.com/dev-notes/adding-support-for-rbd-to-stgt/ guide
When i launch the command:
tgtadm --lld iscsi --mode logicalunit --op new --tid 1 --lun 0
--backing-store iscsi-image --bstype rbd
fails
First i think that lun cannot be 0 because lun 0 is used by the
controller (previous command)
This worked when I first wrote the backend, but tgt may have
changed; I'll investigate and change the blog entry if so. Thanks.
If i launch the correct command with lun 1 i have this error:
tgtadm: invalid request
In syslog:
Jul 10 12:54:03 datastore-lnx001 tgtd: device_mgmt(245) sz:28
params:path=iscsi-image,bstype=rbd
Jul 10 12:54:03 datastore-lnx001 tgtd: tgt_device_create(532)
failed to
find bstype, rbd
What's wrong? not supported?
Where did you get your tgtd? Was it built with rbd support
(CEPH_RBD defined
in the environment for make)?
sudo ./tgtadm --lld iscsi --op show --mode system
should tell you.
How did you set up access to ceph.conf?
