We had a zpool setup with raidz2, named sysvol. 2 of the drives needed to be replaced and I thought I replaced the correct disks, but I ended up replacing 2 of the 'Online' disks (mfid4 and mfid5). After I replaced the disks, the zpool status showed sysvol as unavailable and the 2 disks mfid4 and mfid5 then appeared as unavailable. I put the old disks back, thinking it would see the old disks and sysvol would go back to an online state. That didn't happen. I restarted the server, but it still showed sysvol as unavailable. In a panic, I destroyed the zpool then recreated sysvol and restored from a snapshot that was on our backup server. On sysvol, the only volume that has a backup snapshot on our backup server was sysvol/server. We have another volume, sysvol/2016, that was not backed up. Is there anyway to recover the data that was stored on sysvol/2016?
