Dear ZFS-Users,
I am using Solarisx86 10u10, All the devices which are belongs to my zpool
are in available state .
But I am unable to import the zpool.
#zpool import tXstpool
cannot import 'tXstpool': one or more devices is currently unavailable
==
bash-3.2# zpool import
I understand that some participants would prefer to keep their participation
non-public, and so I do not expect the Group to have a home page at this time.
In the absence of a web page, please can we list here the individual and
organisational members who are *happy* for their membership to be

The copies thing is a really only for laptops, where the likelihood of
redundancy is very low

Availability of the DDT is IMHO crucial to a deduped pool, so
I won't be surprised to see it forced to triple copies.
Agreed, although, the DDT is also paramount to performance.

Hi
Try
zpool import -nF tXstpool
To see
If it can roll back to some. Good state
If you can afford some lost data
zpool import -F tXstpool

Personally, I've never been supportive of the whole copies idea. If you need more than
one redundant copy of some data, that's why you have pool redundancy. You're just hurting
performance by using copies. And protecting against

Hello,
I recently rebooted my workstation and the disk names changed causing my
ZFS pool to be unavailable.
I did not make any hardware changes? My first question is the obvious?
Did I loose my data? Can I recover it?
What would cause the names to change? Delay in the order that the HBA

Hi--
If the S10 patch is installed on this system...
Can you remind us if you ran the zpool online -e command after the
LUN is expanded and the autoexpand propery is set?
I hear that some storage that doesn't generate the correct codes
in response to a LUN expansion so you might need to run

Agreed, ARC/L2ARC help in finding the DDT, but whenever you've got a snapshot

Hello,
I have run zpool online -e only.
I have not set autoexpand property, (as it is not set by default.)
(My understanding was that a controlled way of expansion is zpool online -e,
where you decide when to increase actually,
