[lustre-discuss] Zfs backend file system level backup

[Yong, Fan]

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.

Subject: [lustre-discuss] Zfs backend file system level backup

Hi,
I wish to perform a zfs backend file system 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.
