[zfs-discuss] Re: Is there an idiot's guide to creating network access for users?
Warning: You are now entering The Bad Joke Zone!!! Well, I'm actually leaning more towards Linedance... Thank you. You are now exiting The Bad Joke Zone. Sorry, just had to get that one off my chest...sort of to conceal that I haven't got the foggiest idea. I didn't even know that there were different methods. I have downloaded the DVD image and I'm going to start installing tomorrow morning. I suppose I can say with confidence that I would prefer to use the easiest method available! :-) The thing is I don't really need anything more fancy than to be able to have user groups where the groups can either only read, both read and write or none of the above. Certain movies should only be accessible from the bedroom, for instance... ;-) But then this is very basic, I suppose. So what method would you recommend for this? I know absolutely nothing about *Nix (isn't that the correct lingo?) yet, but I'm pretty good at learning as I go. I have an 80 gig drive that I'm gonna use as a root drive (I think that's what it's called), and I think my first ZFS experiments will be with a partition on that, without risking my DVD/HD collection in the beginning. If possible I will do the install with the drive connected to the PCI IDE card since the first drive on that shows up as the first drive on the computer (don't know why, all other motherboards I used had this on before has put the mobo IDE ports first). I'm so stupid I don't yet know if I'm gonna see a GUI when OpenSolaris is installed or only a command line. But what I see doesn't really matter, I will see and conquer! :-) Tor This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] Are media files compressable with ZFS?

But is there any point in using compression on my media file server, that will store ripped DVD's (which are compressed in their default state), our digital photos (JPEG - also compressed) and HD files (mostly .ts (transport stream) - also a form of compressionI). In other words can ZFS compress compressed files? Or should I just forget about having compression enabled? You can't compress encrypted files -- being able to would indicate that the crypto is broken. You can't compress already-compressed data. Not all data can be compressed by a given algorithm. Turning on compression for some ZFS filesystem and then writing pre-compresed or encrypted data to that filesystem will only waste CPU cycles though -- ZFS will try to compress the data, fail to get a good enough compression ratio, and then store the data without compression.

[zfs-discuss] .zfs snapshot directory in all directories
Since I have been unable to find the answer online, I thought I would ask here. Is there a knob to turn to on a zfs filesystem put the .zfs snapshot directory into all of the children directories of the filesystem, like the .snapshot directories of NetApp systems, instead of just the root of the filesystem?

[zfs-discuss] Efficiency when reading the same file blocks
if you have N processes reading the same file sequentially (where file size is much greater than physical memory) from the same starting position, should I expect that all N processes finish in the same time as if it were a single process? In other words, if you have one process that reads blocks from a file, is it free (meaning no additional total I/O cost) to have another process read the same blocks from the same file at the same time?

Yes I would expect them to finish the same time. There should be no additional reads because the data will be in the ZFS cache (ARC). Given your question are you about to come back with a case where you are not seeing this?

If you are not super-user, why do you care? If you're not the super-user there's no way you can use it locally (as a non-superuser) that I can think of. -frank ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

I mean in case my admin is not using that can i test it locally. df(1M) and mount(1M) show the types of mounted filesystems (e.g., df -n . shows the type of filesystem that contains the shell's current directory.) As Dudekula points out, fstyp(1M) shows the type of filesystem contained in a device (or file), sortof like a file(1) command specifically geared to know only about filesystem types (and to look in devices). As Frank points out, unless the administrator delegates some power to you you won't be able to play with ZFS.
