No. The default used to be 64 KiB; in the Octopus / Pacific era code improvements were made that allowed the defaults to change to 4 KiB. This is baked into each OSD, which is why I asked how I did: you can inject or set in central config or ceph.conf a value different from how a given OSD was built, but it doesn’t actually take effect. This is a subtlety often missed, in fact just last week I worked with a vendor doc team to correct their docs. _______________________________________________ ceph-users mailing list -- [email protected] To unsubscribe send an email to [email protected]
