hmmm... more and more PGs are broken:

:/

at the risk of making a fool of myself, but how do i check what data is in a PG?

https://docs.ceph.com/en/pacific/man/8/ceph-objectstore-tool/


i have already done a backup at the beginning using "cephfs-journal-tool journal export backup.bin", there is only a limited backup of the data itself from the ceph.

With a backup I meant the data outside of Ceph. Journal backup is of course also good to have.

I guess with "ceph health detail" you would get more information about the inconsistent PGs. And with the objectstore tool you can check what objects might be damaged.
