ceph-deploy: error: unrecognized arguments: --data

Question

I am trying to install ceph and configure on a mounted disk. I have the disk location, however, I face a problem when I use the --data parameter.

command: ceph-deploy osd create --data /home/ceph-admin/ceph-data/vda node-ip-address

error: ceph-deploy: error: unrecognized arguments: --data

ceph version: ceph version 14.2.8 (2d095e947a02261ce61424021bb43bd3022d35cb) nautilus (stable)

ceph-deploy version: 1.5.38

All the documentations I found uses the --data parameter. is there any workaround?

please help!

Thanks in advance..

You have to upgrade your ceph-deploy to version 2.x to be able to deploy nautilus to your cluster. The sample commands to update ceph-deploy on ubuntu.

$ wget -q -O- 'https://download.ceph.com/keys/release.asc' | sudo apt-key add -
$ echo deb https://download.ceph.com/debian-nautilus/ $(lsb_release -sc) main | sudo tee /etc/apt/sources.list.d/ceph.list
$ sudo apt update
$ sudo apt install ceph-deploy

Hope it can help.

Reviewing https://docs.ceph.com/docs/nautilus/man/8/ceph-deploy/#osd, I believe you need to point directly at a disk, not a filesystem path.

The example in https://docs.ceph.com/docs/nautilus/rados/deployment/ceph-deploy-osd/ also suggests so:

ceph-deploy osd create --data /dev/ssd osd-server1

i.e. unmount /home/ceph-admin/ceph-data/vda and point directly to device location shown by lsblk.
