Re: [zfs-discuss] Missing zpool devices, what are the options
Quoth Mark Ashley on Mon, Nov 12, 2007 at 11:35:57AM +1100: Is it possible to tell ZFS to forget those SE6140 LUNs ever belonged to the zpool? I know that ZFS will have probably put some user data on them, but if there is a possibility of recovering any of those zvols on the zpool it'd really help a lot, to put it mildly. My understanding is all the metadata will be spread around and polluted by now, even after a few days of the SE6140 LUNs being linked, but I thought I'd ask. No. I believe this is 4852783, reduce pool capacity, which hasn't been implemented yet. (I don't know whether it's being worked on.) I think your best bet is to copy off any data you can get to, and recreate the pool.

[zfs-discuss] Missing zpool devices, what are the options
We had a 'windoze' zpool on two internal disks. It had a number of zvols which were ISCSI'd out to a few hosts. This has been in and running for some months. Recently someone added some external SE6140 LUNs to the zpool as well, and last friday those LUNs were deleted from the SE6140 itself, as far as I know they aren't recoverable at all. Is it possible to tell ZFS to forget those SE6140 LUNs ever belonged to the zpool? I know that ZFS will have probably put some user data on them, but if there is a possibility of recovering any of those zvols on the zpool it'd really help a lot, to put it mildly. My understanding is all the metadata will be spread around and polluted by now, even after a few days of the SE6140 LUNs being linked, but I thought I'd ask. Any attempt to remove the devices just produces a zpool unavailable message. The machine is running Sol 11 snv_64a on a T2000. ta, Mark. pool: windoze state: UNAVAIL status: One or more devices could not be opened.
