I think “ceph pg dump” is what you’re after, look for the “UP” and “ACTIVE” fields to map a PG to an OSD. From there it’s just a matter of verifying your PG placement matches the CRUSH rule. From: Christopher Durham <caduceus42@xxxxxxx> Date: Wednesday, January 11, 2023 at 3:56 PM To: ceph-users@xxxxxxx <ceph-users@xxxxxxx> Subject: [EXTERNAL] pg mapping verification Hi, For a given crush rule and pool that uses it, how can I verify hat the pgs in that pool folllow the rule? I have a requirement to 'prove' that the pgs are mapping correctly. I see: https://pypi.org/project/crush/ This allows me to read in a crushmap file that I could then use to verify a pg with some scripting, but this pypi is very old and seems not to be maintained or updatedsince 2017. I am sure there is a way, using osdmaptool or something else, but it is not obvious. Before i spend alot of time searching, I thought I would ask here. Basically, having a list of pgs like this: [[1,2,3,4,5],[2,3,4,5,6],...] Given a read-in crushmap and a specific rule therein, I want to verify that all pgs in my list are consistent with the rule specified. Let me know if there is a proper way to do this, and thanks. -Chris _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
