I used to have a tool from hgst/wd to 'convert' drives to 4Kn, but after a mentally challenging interaction with some wd support, I decided to try and use other solutions mentioned on the internet this seems to produce output similar to the previously used tool sg_format --format --size=4096 /dev/sdd Anyone have experience with this? This is first time the drives are already in the nodes, so I don't have a power cycle on them. _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
