You can see what your drive supports (and what is active) with "smartctl -c /dev/nvme0n1" (or other if you have more than one) and look at the "Supported LBA Sizes". You can use the nvme command from the nvme-cli package to change it (if your drive supports more than one), and changing it destroys all the contents of the drive. You can't necessarily just restore a filesystem image back to it either; a number of FSes have the underlying raw block size as a basic assumption that cannot be changed after the FS is created. Even if the presented raw sector size is 512, the drive can typically report the "optimal" size as 4096 (and Linux then uses that info). -- Chris Adams <linux@xxxxxxxxxxx> -- _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
