Very much multithreaded just like the rest of the Solaris kernel.

oops, I mean 2 cores.
Anyway I'm having second thoughts about this board now because the northbridge
sounds like a power hog and I was planning a passive cooled system. Also I

How can you disable the auto-snapshot service[s] by default without disabling
the timeslider as well which appears to be the case if you disable the smf
services.
Setting the properly in the root pool is ok except for removable media which I

Chris,
Tim Foster sent out this syntax previously:
zfs set com.sun:auto-snapshot=false dataset
Unless I'm misunderstanding your questions, try this for the dataset
on the removable media device.
Let me know if you have any issues.
I'm tracking the auto snapshot experience...

Not sure I follow - time slider depends on the auto-snapshot service to
take snapshots... (doe
You may want to ask your SAN vendor if they have a setting you can make
to no-op the cache flush. That way you don't have to worry about the
flush behavior if you change/add different arrays.

Yep, it uses "zfs snapshot -r" when it can, degrading to snapshots of
the individual datasets it can't recursively snapshot and recursiv

Yep, time-slider depends on auto-snapshot.

Yep, you can do that. It uses ZFS user properties and respects

Aah I see. That's the complete opposite of what the desktop folk wanted

Hi all,
I've got a lot of video files on a zfs/cifs fileserver running SXCE. A
little while ago the dual onboard NICs died and I had to replace them with a
PCI 10/100 NIC. The system was fine for a couple of weeks but now the
performance when viewing a video file from the cifs share is appauling.
How can I verify the checksums for a specific file?

ZFS doesn't checksum files. So a file does not have a checksum
to verify. Perhaps you want to keep a digest(1) of the files?

If you downloaded a file, enter

For MD5 checksums personally I favour MD5Summer on Windows boxes.
Just watch the formatting of the checksum file if you're checking
downloads - sometimes it can be a bit picky about linebreaks. I think
this file might have been the latest preview release of Netbeans 6.5
