A Ceph OSD generally consists of one ceph-osd daemon for one storage drive and its associated journal within a node. If a node has multiple storage drives, then map one ceph-osd daemon for each drive. Red Hat recommends checking the capacity of a cluster regularly to see if it is reaching the upper end of its storage capacity.. The cluster will start rebalancing when osd's are added to the cluster, unless "osd crush initial weight = 0" has been added to the ceph.conf prior to deploying the osd's. " ceph osd df tree" will show pg's being added to the new osd's. Stage.3 will run for a period of time after all of the osd's have been deploy. This is normal.

NOTE: With ceph-volume the charm relies on unified prepare+activate functionality of 'ceph-volume lvm create' (only that command is used in osdize_dev and ceph.start_osds is extraneous for LVM-based setups):. Shared Filesystem (CephFS) This method allows clients to jointly access a shared POSIX compliant filesystem. The client initially contacts the Meta Data Server to obtain the location of the object (s) for a given inode and then communicates directly with an OSD to perform the final IO request.

Run the job: kubectl create -f osd-purge.yaml When the job is completed, review the logs to ensure success: kubectl -n rook-ceph logs -l app=rook-ceph-purge-osd. The default disk path of ceph-base is currently set to: '/dev/sdb'. You have to set it to the path of your disk for the ceph-osd data ('/dev/vdb'): $ juju config ceph-osd osd-devices /dev/sdb $ juju config ceph-osd osd-devices='/dev/vdb' The disk should have no partitions on it when you configure it.

This approach allows Ceph to more effectively leverage the intelligence (CPU and memory) present on each OSD to achieve reliable, highly available object storage with linear scaling. We describe the operationof the Ceph client, metadata. Ceph OSD Daemons write data to the disk and to journals. So you need to provide a disk for the OSD and a path to the journal partition (i.e., this is the most common configuration, but you may configure your system to your own needs).
