MicroCeph
Ubuntu 22.04 LTS MicroCeph with Snap
These installation instructions use MicroCeph - Ceph in a snap. MicroCeph is a pure upstream Ceph distribution designed for small scale and edge deployments, which can be installed and maintained with minimal knowledge and effort.
Install Ceph on Ubuntu | Ubuntu https://ubuntu.com/ceph/install
Note: If snap is not installed:
sudo apt install snapd
Install microceph:
sudo snap install microceph
Bootstrap cluster from first node:
sudo microceph cluster bootstrap
From first node add other nodes:
sudo microceph cluster add node[x]
Copy join output onto node[x]:
sudo microceph cluster join [pasted-output-from-node1]
Check status:
sudo microceph.ceph status
Add some disks to each node (as OSDs):
sudo microceph disk add /dev/sd[x] --wipe
Config files are found at:
/var/snap/microceph/current/conf/ /var/snap/microceph/current/conf/ceph.conf /var/snap/microceph/current/conf/metadata.yaml /var/snap/microceph/current/conf/ceph.keyring
ln -s /var/snap/microceph/current/conf/ceph.conf /etc/ceph/ceph.conf
Verify cluster:
sudo microceph.ceph status sudo microceph.ceph osd status
microceph disk list
Create File System
Local Mount
If you are on one of the cluster nodes, and if you look at the ceph.keyring, you will notice the default user was likely 'admin' (client.admin).
Assuming /etc/ceph/ceph.keyring exits:
mount -t ceph :/ /mnt -o name=admin
New style, with the mount.ceph helper, assuming the fs was created as 'mycfs':
mount.ceph admin@.mycfs=/ /mnt
# Or: mount -t ceph admin@.cfs=/ /mnt
Specify it all:
mount -t ceph {device-string}={path-to-mounted} {mount-point} -o {key-value-args} {other-args}
mount -t ceph <name>@<fsid>.<fs_name>=/ /mnt
mount -t ceph cephuser@.cephfs=/ /mnt -o secretfile=/etc/ceph/cephuser.secret
mount -t ceph cephuser@.cephfs=/ /mnt -o secret=AQATSKdNGBnwLhAAnNDKnH65FmVKpXZJVasUeQ==
