With zfs take df output with a grain of salt -- add more if compression is turned on. ZFS being quite complicated, it seems only an "approximate" free space is reported, which won't be too wrong and would suffice for the purpose. But if you're expecting it to be correct to the last block,it won't be. > 2) If this is normal overhead, then how to you > examine these aspects > of the fs (commands to use, background links to read, > etc. (If you say > RTFM then please supply a page number for > "817-2271.pdf"))? No public mechanism currently exists, afaik. Some black magic with dtrace might be possible to look at the FS data structures OR by reading the code and ZFS on-disk format document one /could/ possibly figure it out. > 3) What's the relationship between pools (zpool) and > filesystems (zfs > command)? / Is there a default fs created hwne the > pool is created? Yes. As soon as you create a pool, it can be used as a FS. Nothing else needed. You can of course, create additional filesystems in the pool, but one is always available to you (you may or may not like it... I keep it unmounted). > 4) BONUS QUESTION: Is Sun currently using / promoting > / shipping hardware that *boots* ZFS? (e.g. last I checked even > stuff like "Thumper" did not use ZFS for the 2 mirror'd boot > drives (UFS?) but used ZFS for the 10,000 other drives (OK, maybe there > aren't 10,000 drive but there sure are a lot)). ZFS boot didn't get integrated into even Nevada until very recently, let alone backported to Solaris 10. I doubt it is ready for production use yet. The new "Opensolaris Dev. preview aka. Project Indiana" by default installs ZFS boot (no UFS needed). So, things are moving but we still need to go a long way before all things are stabilized, documented, corner cases identified, recovery tools & OS install/update applications updated etc etc > 5) BONUS QUESTION #2: How does a frustrated yet > extremely seasoned Mac/ > OS X technician with a terrific Solaris background > find happiness by landing a job at his other favorite company, Sun? (My > "friend" wants to know.) WARNING: Zen mode ON! One has to find happiness within. A more correct question might be: Would it be better for you to switch to working for Sun ? Well I personally admire Sun's engineering. It's one of the *few* places left where you are allowed to dream, and of course, build! If that is what you want to do, you might like working for them very much! > 6) FINAL QUESTION (2 parts): (a) When will we see > default booting to > ZFS? You can see it now... download the "OpenSolaris Developer Preview" live CD and install it to HDD. It's there! > (b) [When] will we see ZFS as the default fs > on OS X? Only when uncle Stevie says so!
