It's easy to install tgtd with ceph support. ubuntu 12.04 for example:
Connect ceph-extras repo:
echo deb http://ceph.com/packages/ceph-extras/debian $(lsb_release
-sc) main | sudo tee /etc/apt/sources.list.d/ceph-extras.list
Install tgtd with rbd support:
apt-get update
apt-get install tgt
It's important to disable the rbd cache on tgtd host. Set in
/etc/ceph/ceph.conf:
[client]
rbd_cache = false
[...]
Hello,
Without cache on the tgtd side, it should be possible to have failover
and load balancing (active/avtive) multipathing.
Have you tested multipath load balancing in this scenario ?
If it's reliable, it opens a new way for me to do HA storage with iSCSI !
