It can be done anytime before umount the Lustre device, in spite of whether it is new formatted system or live zfs-based system with data, as long as the version supports file-level backup.

The Lustre manual says to to: lctl set_param osd-zfs.${fsname}-${target}.index_backup=1 Does this have to be done right at the start before the file system has been used, or can it be done to a live file system with data already on it? Thanks, Alastair. _______________________________________________ lustre-discuss mailing list [email protected] http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org _______________________________________________ lustre-discuss mailing list [email protected] http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org
