Hi, we run a 3 node cluster, every node runs a mon and 4 osds. 2 defined pools, one with replication level 2, the second with replication level 3. We now want to relocate one node from one datacenter to another, which means a downtime of about 4 hours for that specific node, which shouldn't hurt the cluster, as 2 nodes are still working. But is there anything special we should consider or do beforehand, besides praying that nothing bad will happen with the remaining two nodes? Thanks for your help, best regards, Kurt -- Kurt Bauer <kurt.bauer@xxxxxxxxxxxx> Vienna University Computer Center - ACOnet - VIX Universitaetsstrasse 7, A-1010 Vienna, Austria, Europe Tel: ++43 1 4277 - 14070 (Fax: - 814070) KB1970-RIPE
