ceph disk

[gYanis]

Hello,


I would like to install ceph. but after the installation I have an error message

rados_connect failed - No such file or directory (500)

It seems to me that it is a problem with the ceph disk.

How to create it?
It must completely replace the one in LVM?

What size recommended?
I have done lots of tests but I have not found.





Why during a VM migration the disk is not migrated?
Is it a manipulation to do in addition?


cordially

Hello,

missing config file,

pleac check on all your nodes if you have :
/etc/ceph/ceph.conf
/etc/pve/ceph.conf

sym link from /etc/ceph/ceph.conf to -> /etc/pve/ceph.conf

What exactly did you do either in the GUI or on the CLI?

How to create it?

If you have installed and configured it (have a valid ceph.conf file, see the previous answer by @CyberGuy ) you can create OSDs via the GUI or on the CLI with pveceph osd create /dev/sdX. You will need an empty disk for this.
