xie xingguo d792e8d528 crush: "osd crush class rename" support ... In 076a6abd80 I killed the 'class rename' command and thought it was totally useless but I was wrong. Consider the following user case: (1) randomly choose some OSDs(e.g., from different hosts) and try to make them for private use only, say, by grouping them into 'pool1' (2) ceph osd crush set-device-class pool1 'OSDs from (1)' (3) ceph osd crush rule create-replicated rule_for_pool1 default host pool1 (4) ceph osd pool rename pool1 pool2 (5) ceph osd crush class rename pool1 pool2 From the above user case, we need to safely change a pool name without worrying any risk of data migration. That is why the 'osd crush class rename' command is still needed here. Signed-off-by: xie xingguo <xie.xingguo@zte.com.cn>		2017-08-11 08:32:39 +08:00
