Good morning Q: Is it possible to have a 2nd cephfs_data volume and exposing it to the same openstack environment?
Reason being: Our current profile is configured with erasure code value of k=3,m=1 (rack level) but we looking to buy another +- 6PB of storage w/ controllers and was thinking of moving to an erasure profile of k=2,m=1 since we're not so big on data redundancy but more on disk space + performance. For what I understand you can't change erasure profiles, therefor we need to essentially build a new ceph cluster but we're trying to understand if we can attach it to the existing openstack platform, then gradually move all the data over from the old cluster into the new cluster, destroy the old cluster and integrated it with the new one. If anyone has any recommendations to get more space out + performance at the cost of data redundancy with at least 1 rack please let me know as well.
