I have two testing clusters and now working on inter-cluster failover<br>
with stacked drbd and booth.<br></blockquote></div><br>Luster looks very cool and stability, but it doesn't provide scalable block device (Ceph allow it throw RDB), require patched kernel (i doesn't find more modern patched kernels for ubuntu lucid), so i think that it doesn't acceptable for my use case<br>
