  • Project changed from Ceph to Orchestrator
  • Subject changed from 15.2.4 and ceohadm - mds not starting to 15.2.4 and cephadm - mds not starting

Here is how I do it:

https://docs.ceph.com/docs/master/cephfs/fs-volumes/#fs-volumes

"This creates a CephFS file system and its data and metadata pools. It also tries to create MDSes for the filesystem using the enabled ceph-mgr orchestrator module (see Orchestrator CLI) , e.g. [cephadm]."

In your case, it looks like you have already created the CephFS file system and its data and metadata pools, and now you want to deploy MDSes in order to be able to use it. The documentation for that is here:

https://docs.ceph.com/docs/master/cephadm/install/#deploy-mdss

"One or more MDS daemons is required to use the CephFS file system. . . . To deploy metadata servers:

ceph orch apply mds *<fs-name>* --placement="*<num-daemons>* [*<host1>* ...]"
