[DRBD-user] drbdmanage upgrade to linstor

Hello,

I tried the lost command even when the satellites are stopped, but the

What do you mean with "the command isn't available"?
If you already have added a node to LINSTORs database (you can check with
`linstor node list` ), and the satellite is currently OFFLINE, then you
should be able to use
`linstor node lost $nodeName`.
You might get an error if the node does not exist or if the node is ONLINE.

If any other satellite is ONLINE, deleting a resource will trigger an
update of the DRBD .res file for the specific resource on all affected (and
ONLINE) satellites. That means that the .res files will be updated as if
you have intentionally deleted the peer-resource. I assume you do not want
that during a drbdmanage -> linstor migration.

If you are using LINSTORs default H2 database you can simply stop the
controller, remove the file /var/lib/linstor/linstordb.mv.db and restart
the controller.
If you are using another database, you will most likely have to open a
connection to the database and clear it with SQL statements.

I could run the commands

   linstor node info
That should give you an overview about what layers and storage providers
are supported by which node and also at least a hint why a certain layer or
storage provider is not supported.
(btw - the `linstor node create ...` command should also return you such
info for the just created node)
In your case I'd guess you are missing the package
"thin-provisioning-tools"? or even the whole "lvm2" package? :)
