No need to keep any config - setup the osds again, moving them is a thing I did not try and seems to be to much of an effort, easier to reinstall. best regards Ralf Am 12/07/2021 um 09:01 schrieb Christoph Weber: > Thanks for your advice, Ralf and Eneko , > > @Ralph >> please read the documentation about removing/replacing a Node carefully >> - you may not reinstall it with the same IP and/or Name as this will crash your >> whole cluster! > This is my bigges fear ... > > Thanks for pointing me to the manual - there is in fact an detailed explanation which files to keep before reinstalling the node under "Re-installing a cluster node". > > This is excactly what I was looking for, with detailed step-by-step walktrough.

I thought it might just relocate the ODSs location in the crush map from node3 to node6 when I shut down the prodve3, remove the disks and reinsert them in node 6?
