<font size="2"><div class="PlainText">Hi, we have Lustre 2.7.58 in place on our OST and MDT/MGS (combined). <br>
Underlying the lustre file system is a raid-z2 zfs pool.<br>
<br>
A few days ago, we lost 2 disks at once from the raid-z2. I replaced <br>
one and a resilver started, that seemed to choke. So, I put back both <br>
disks with replacements, and the new re-silver shows the following now.<br>
<br>
[root@umdist03 ~]# zpool status -v ost-007<br>
pool: ost-007<br>
state: DEGRADED<br>
status: One or more devices has experienced an error resulting in data<br>
corruption. Applications may be affected.<br>
action: Restore the file in question if possible. Otherwise restore the<br>
entire pool from backup.<br>

<br>
what are my options here? If I don't care about the file, can I <br>
identify it and then just delete it? Or is my only real option to drain <br>
the pool and rebuild it cleanly?<br>
<br>
Thanks for any help/advice.<br>
