Hey, that's nothing, I had one zfs file system, then I cloned it, so I
thought that I had two separate file systems. then I was making snaps
of both of them. Then later on I decided I did not need original file
system with its snaps. So I did recursively remove it, all of a sudden

Yes, i am also interested in this.
We can't afford two super fast setup so we are looking at having a huge pile
sata to act as a real time backup for all our streams.
So what can AVS do and its limitations are?
Would a just using zfs send and receive do or does AVS make it all seamless?

queuing theory should explain this rather nicely. iostat measures
%busy by counting if there is an entry in the queue for the clock
ticks. There are two queues, one in the controller and one on the
disk. As you can clearly see the way ZFS pushes the load is very
different than dd or UFS.

Unless I misunderstand ZFS, you can archive the contents of a

Hello all, I am interested in setting up an HA NFS server with zfs as
the storage filesystem on Solaris 10 + Sun Cluster 3.2. This is an HPC
environment with a 70 node cluster attached. File sizes are 1-200meg
or so, with an average around 10meg.

An example would be if you had a raw snapshot on tape. A single file or subset
of files could be restored from it without needing the space to load the full
snapshot into a zpool. This would be handy if you have a zpool with 500GB of
space and 300GB used. If you had a snapshot that was 250GB
This is probably a good place to start.

What else do you think we should be doing?

I'm not sure what you want that the file system does not already provide.
you can use cp to copy files out, or find(1) to find them based on time or any
other attribute and then cpio to copy them out.

I think it would be handy if a utility could read a full zfs snapshot and
restore subsets of files or directories like using something like tar -xf or
