Hi Mosharaf - I will check it but I can assure that this error is a CLI error and the command has not impacted the system or the data. I have no clue what happened - I am sure I tested this scenario. The command syntax is ceph osd rm-pg-upmap-primary <PGID> the error you get is because you did not specify the pg id. Run this command in a loop for all pgs in a pool to return the pool to its original state, Regards, Josh On Thu, Sep 14, 2023 at 4:24 PM Mosharaf Hossain < mosharaf.hossain@xxxxxxxxxxxxxx> wrote: > Hello Josh > Thank you your for reply to us. > > After giving the command in the cluster I got the following error.
