Hello,
I've looked around Google and the zfs-discuss archives but have not been
able to find a good answer to this question (and the related questions
that follow it):
How well does ZFS handle unexpected power failures? (e.g. environmental
power failures, power supply dying, etc.)
Does it c

Hi,
Is there a time frame when L2ARC would be available in Solaris 10. With
the latest U7 release, L2ARC appears to be disabled (operation not
supported on this type of pool).
Thanks,

Hi Patrick,
To answer your original question, yes, you can create your root swap
and dump volumes before you run the lucreate operation. LU won't change
them if they are already created.
Keep in mind that you'll need approximately 10 GBs of disk space for the
ZFS root BE and the swap/dump volume

This can occur if the location of the end of the partition has

Hi,
you have to upgrade your pool:
The pool is formatted using an older on-disk version.
# *zpool upgrade -v*
Then it should works fine.
