However, we weren't sure if that would capture all the internal Lustre data. Specifically the note in 18.3.1 about index backups made us think it wouldn't for version 2.10.X. Also the fact that ldiskfs backups and LVM snapshots are detailed in the manual but ZFS snapshots are not caused us to think they wouldn't work, at least with our older lustre version. Maybe we were taking things too literally. Would a ZFS snapshot contain all the Lustre data?<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, Sep 16, 2022 at 7:45 AM Mohr, Rick <<a href="mailto:mohrrf@ornl.gov">mohrrf@ornl.gov</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Liam,<br>

If you have another zpool configured somewhere, you could always take a snapshot of your mdt and then used send/received to copy that snapshot to another zpool. I helped someone do this one time in order to move the mdt to new hardware.<br>
