I'm currently using sheepdog v0.3.0 (2 copies) with qemu 1.0 (fedora 17 backported to centos 6.2) on my pre-production cluster running on 4 machines. The current status seems to be fine with some rarely qemu segfault mentioned earlier by 'David Douard'. The performance is impressive and the cluster recovery process seems working properly when i got storage problem last week on one node.<div>
<div><br></div><div><div>Now I'm testing the recent sheepdog on git with my test cluster (running in 3 VMs with 2 copies) and found that the storage backend has been changed from 'simple' to 'farm'. I still haven't test the upgrade procedure from v0.3.0 yet since my test cluster have some task to do so may I ask if there's any 'ONLINE' upgrade procedure to upgrade sheepdog from v0.3.0 to current master version on git? The process I planned to use is by following:</div>
<div><br></div><div>- kill 1 node and remove from cluster</div><div>- upgrade to the recent sheepdog version.</div><div>- clear all the target backend folder used by old sheepdog. (rm -rf /var/sheepdog ?)</div><div>- start sheepdog again and wait until cluster recovery process done.</div>
<div>- then do the above process with each other machines until complete.</div><div><br></div><div>Is there anything I should take care of?</div><div><br></div><div>Best Regards,</div><div><br></div><div><br></div><div><br>
