Yes, I think Eric is correct. Funny, this is an adjunct to the thread I started entitled "Thoughts on ZFS Pool Backup Strategies". I was going to include this point in that thread but thought better of it.
It would be nice if there were an easy way to extract a pool configuration, with all of the dataset properties, ACLs, etc. so that you could easily reload it into a new pool. I could see this being useful in a disaster recovery sense, and I'm sure people smarter than I can think of other uses. >From my reading of the documentation and man pages, I don't see that any such command currently exists. Something that would allow you dump the config into a file and read it back from a file using typical Unix semantics like STDIN/STDOUT. I was thinking something like: zpool dump <pool> [-o <filename>] zpool load <pool> [-f <filename] Without "-o" or "-f", the output would go to STDOUT or the input would come from STDIN, so you could use this in pipelines. If you have a particularly long lived and stable pool, or one that has been through many upgrades, this might be a nice way to save a configuration that you could restore later (if necessary) with a single command.
