This should work and should be as fast as it can be: wipefs -a /dev/sdX shred /dev/sdX Whether or not that's "GDPR compliant" will depend on external certification, I guess. (The issues might be that you can't guarantee all blocks in an SSD/HDD are actually erased because the device firmware may retire bad blocks and make them inaccessible. It may not be possible for the device to physically destroy those blocks either even with SMART directives. You may be stuck with an industrial shredder to be compliant if the rules are stringent.) -- Patrick Donnelly _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
