Hi,
Anyway, are there other devices out there that you would recommend to use as
a slog device, other than this nvram card, that would present similar
performance gains?
Thanks

Turns out zfs mount -a will pick up the file system.
Fun question is why the OS can't mount the disk by itself.
gnome-mount is what puts up the "Can't access the disk"
and whines to stdout (/dev/null in this case) about:

Ok, this is not a OpenSolaris question, but it is a Solaris and ZFS
question.
I have a pool with three mirrored vdevs. I just got an error message

i removed the files that were corrupted,scrubbed the datatank mirror and the
did status -v datatank and i got this :
pool: datatank
state: DEGRADED
status: One or more devices has experienced an unrecoverable error. An
attempt was made to correct the error. Applications are unaffected

Hi everyone,
i did a nice install of opensolaris and i pulled 2x500 gig sata disk in a zpool
mirror.
Everything went well and i got it so that my mirror called datatank got shared
by using CIFS. I can access it from my macbook and pc.
So with this nice setup i started to put my files on but now

It should, but because of its copy-on-write nature, fragment

Hmmn, you might want to look at Andrew Tridgell's' thesis (yes,
Andrew of Samba fame), as he had to solve this very question
to be able to select an algorithm to use inside rsync.

Disk seeks are the bane of existing storage systems since they come

Just going to make a quick comment here. It's a good point about wanting
backup software to support this, we're a much smaller company but it's already
more difficult to manage the storage needed for backups than our live storage.
However, we're actively planning that over the next 12 months, Z

Hello All,
Is there a way I can remove my old boot environments? Is it as simple as
performing a 'zfs destroy' on the older entries, followed by removing the entry
from the menu.lst?? I have been searching, but have not found anything... Any
help would be much appreciated!!

James,
May I ask what kind of USB enclosures and hubs you are using? I've had some
very bad experiences over the past month with not so cheap enclosures.
Wrt esata, I found the following chipsets on the SHCL. Any others you can
recommend?
Silicon Image 3112A

Not for my customer. Internal accounting means that the storage team gets paid
for each allocated GB on a monthly basis. They have
stacks of IO bandwidth and CPU cycles to spare outside of their daily busy
