Hi, I'm using the following 'Getting Started' guide to configure simple cluster: http://www.osrg.net/sheepdog/usage.html I have configured cluster on 1 node/box, so the first questions are: Can I configure cluster on single node (1 box) under CentOS 5.5 x86_64 ? Is it required at least 3 nodes/boxes ... ? I have faced with the following issue on my single-node cluster. I have rebooted the box after my first image creation. The following done for that: - corosync is up and running udp 0 0 192.168.128.195:5404 0.0.0.0:* 3541/corosync udp 0 0 192.168.128.195:5405 0.0.0.0:* 3541/corosync udp 0 0 226.94.1.1:5405 0.0.0.0:* 3541/corosync - sheep is up and running tcp 0 0 0.0.0.0:7000 0.0.0.0:* LISTEN 3561/sheep - cluster is formatted with 1 copy only #collie cluster format --copies=1 - the image with prelocated data is created # qemu-img create sheepdog:test0 -o preallocation=data 4G So after such siple steps I got: # collie vdi list name id size used shared creation time vdi id ------------------------------------------------------------------ test0 1 4.0 GB 4.0 GB 0.0 MB 2010-10-15 12:42 fd34af Then I rebooted the box, and no image(s) are available for me after box came back. The vdi list just show nothing: # collie vdi list name id size used shared creation time vdi id ------------------------------------------------------------------ and 'collie vdi list' never ends ... corosync and sheep are still running. Could somebody assist me with that. Thanks --- Yura |
