After a power outage due to a thunder storm my 3 disk raidz1 pool has become
UNAVAILable.
It is a ZFV v13 pool using the whole 3 disks created on FreeBSD current 8 x64

Hi All,
I have a zfs pool setup on one server, the pool is made up of 4 iSCSI
luns, is it possible to migrate the zfs pool to another server? Each
of the iSCSI luns would be available on the other server.
Thanks,

Well I did have a UPS on the machine :-)
but the machine hung and I had to power it off...
(yep it was vertual, but that happens on direct HW too,
and virtualisasion is the happening ting at sun and else where!
I have a version of the data backed up, but will
take ages (10days) to restore).

That's the stuff. I think that is probably your best bet at the moment. I've
not seen even a mention of an actual tool to do that, and I'd be surprised if
we saw one this side of Christmas.

Thanks a lot, Cindy!
Let me know how it goes or if I can provide more info.
Part of the bad luck I've had with that set, is that it reports such errors
about once a month, then everything goes back to normal again. So I'm pretty
sure that I'll be able to try to offline the disk someday.
OK.
So do we have an zpool import --xtg 56574 mypoolname
or help to do it (script?)

I setup a NAS based on EON 0.58.9-b104 (Osol 2008/11) incl. a zfs (raid-z

Just like sid81 i had the same storm destroying 1 of my drives in the pool.

Hello,
I am new to Solaris.
Several PDFs out there suggest any of the following:
a) Solaris comes with 128bit encryption (full filesystem)
b) Solaris supports full root encryption.
Any truth to any of this?
The company I work for tis mandating full root encryption.
Thanks.

That would be nice. Before developers worry about such exotic
features, I would rather that they attend to the gross performance
issues so that zfs performs at least as well as Windows NTFS or Linux
XFS in all common cases.

Ok, so the choice for a MB boils down to:

I found these 4 AM3 motherboard with optional ECC memory support. I don't
