Well this is a new one Illumos/Openindiana let me add a device as a hot spare that evidently has a different sector alignment than all of the other drives in the array. So now I'm at the point that I /need/ a hot spare and it doesn't look like I have it. And, worse, the other spares I have a

Yeah, I'm having a combination of this and the "resilver constantly restarting" issue. And nothing to free up space. It was recommended to me to replace any expanders I had between the HBA and the drives with extra HBAs, but my array doesn't have expanders. If your's does, you may want to try th

Is there any way to stop a resilver? We gotta stop this thing - at minimum, completion time is 300,000 hours, and maximum is in the millions. Raidz2 array, so it has the redundancy, we just need to get data off. ___ zfs-discuss mailing list zfs-discuss@

What options are there to turn off or reduce the priority of a resilver? This is on a 400TB iSCSI based zpool (8 LUNs per raidz2 vdev, 4 LUNs per shelf, 6 drives per LUN - 16 shelves total) - my client has gotten to the point that they just want to get their data off, but this resilver won't stop.
