You may try recover options(rarely help) from "zpool import" but rebuilding the zpool has huge possibilities.
Thanks. Fred On Fri, Mar 11, 2016 at 5:19 PM -0800, "Bob Ball" <[email protected]<mailto:[email protected]>> wrote: Hi, we have Lustre 2.7.58 in place on our OST and MDT/MGS (combined). Underlying the lustre file system is a raid-z2 zfs pool. A few days ago, we lost 2 disks at once from the raid-z2. I replaced one and a resilver started, that seemed to choke. So, I put back both disks with replacements, and the new re-silver shows the following now.
